1. Introduction
Ehlers-Danlos syndrome (EDS) is an umbrella term for
various hereditary connective tissue disorders (HCTDs)
mainly characterized by congenital joint hypermobility, skin
hyperextensibility,andtissuefragility.Amongthesixmajor
forms [], the classic and the hypermobility (EDS-HT) types
areconsideredthemostcommon.EDS-HTtypicallyfeatures
joint laxity and related complications, chronic/recurrent limb
pain, and minor skin involvement [], although its extended
clinical spectrum covers a wide variety of functional somatic
syndromes []. An international panel of experts now con-
siders EDS-HT one and the same as joint hypermobility
syndrome (JHS) [], and this overlap is particularly evident
in adulthood. e diagnosis of JHS/EDS-HT still remains
unsupported by molecular testing, with the exception of a
very few cases purportedly mutated in COL3A1 and TNXB
[]. More recently, the relevance of previous molecular
ndings has been further reduced by the separation of
patients mutated in TNXB, who are now grouped under a
distinct EDS subtype (i.e., TNXB-decient EDS) []. At the
moment, recognition of JHS/EDS-HI is uniquely based on
clinical diagnostic criteria [,], which needs urgent revision
[].
Pain and fatigue are considered relevant determinants
of disability in JHS/EDS-HT []. However, their manifes-
tations and pathophysiology remain poorly characterized.
Accumulated data demonstrate that pain is oen chronic
BioMed Research International
and widespread in EDS [] and associates positively with
residual joint hypermobility, dislocations, previous surgery,
and low nocturnal sleep quality []. Limb pain, though
considered originating mostly from primary joint damage,
shows some neuropathic features in / patients []. Such
preliminary ndings anticipate a complex pathophysiology
for pain in JHS/EDS-HT, in which cognitive aspects are likely
tostronglyaectqualityoflife.Accordingly,Rombautetal.
[] commonly encountered fear of falling among women
with JHS/EDS-HT.
Chronic musculoskeletal conditions, predominantly
characterized by chronic pain, are oen associated with fear
[]. Fear is the emotional reaction to a specic, identiable,
and immediate threat, such as a dangerous animal or injury
[]. Pain-related fear can be dened as the fear that emerges
when stimuli that are related to pain are perceived as a
main threat []. Fear in relation to pain is described in
three constructs: pain-related fear, fear of movement, and
kinesiophobia []. Kinesiophobia is the most extreme
form of fear of movement, and is dened as an excessive,
irrational and debilitating fear of physical movement and
activity resulting from a feeling of vulnerability to painful
injury or reinjury, and it has been reported as a common
feature of patients with CFS [], bromyalgia, and chronic
low back pain []. Fear-avoidance is said to play a role in
the so-called deconditioning syndrome which can either
be expressed in a weakened muscle strength, or disordered
muscle coordination, during physical activity [].
In this study, we carried out a questionnaire on 
JHS/EDS-HT patients in order to evaluate the presence and
severity of kinesiophobia and to analyze its relationship with
pain, fatigue, and quality of life (QoL). Implications of the
results in the treatment of JHS/EDS-HT are discussed below.
2. Patients and Methods
2.1. Patient Selection. All patients studied have attended
a multidisciplinary service dedicated to HCTDs and were
followed into the “joint hypermobility” outpatient clinic in
the Division of Physical Medicine and Rehabilitation of the
Umberto I University Hospital (Rome, Italy) and into the
clinical genetics outpatient clinic at the Medical Genetics of
the San Camillo-Forlanini Hospital (Rome, Italy). Diagnosis
was based on published diagnostic criteria including the
Brighton criteria for JHS [] and the Villefranche criteria
for EDS-HT []. Patients were included if they met at least
oneofthesetwosets.Inourclinicalpractice,theBrighton
criteria are the most stringent for young-adult, adult, and
elderly patients, while the Villefranche criteria are the best
for individuals in the pediatric age group. For this study,
JHM was mainly assessed applying the Beighton score [].
Further joint or group of joints were equally evaluated
although, at the moment, their status do not inuence

evaluation with attribution of one point in the presence of any
ofthefollowingfeatures:(a)passiveappositionofthethumb

(b) passive dorsiexion of the V nger beyond (one point

assessed qualitatively on the basis of accumulated experience
by palpation and gentle stretching of the skin at the volar
aspect of the palm (at the IV metacarpal) and/or of the
forearm. Other HCTDs were excluded clinically. Patients
were also evaluated to search other secondary symptoms of
the pathology that are showed in Tab l e  .Individualswith
incomplete diagnosis were equally excluded. us, a group
of patients with insucient features of JHS for a rm clinical
diagnosis based on the available diagnostic criteria, but likely
to be liable to develop full-blown JHS, were not included
in this study. Pregnant women and patients older than ,
or younger than , were not included in order to better
homogenize the sample.
2.2. Evaluation Tools. In order to evaluate kinesiophobia,
pain, and fatigue, all patients were asked to ll in a series
of questionnaires including the Tampa Scale Italian version
(TSK-I) [], the Fatigue Severity Scale (FSS) [], the
Multidimensional Fatigue Inventory Scale (MFI-) [], and
the Numeric Rating Scale (NRS-) for pain []. Data were
also compared with quality of life, which was evaluated by the
Medical Outcome Study Short Form- (SF-) [].
BioMed Research International
2.2.1. Kinesiophobia. TSK-I is the most widely used question-
naire to assess pain and pain-related fear of movement in
subjects with musculoskeletal complaints [,], and this
hasbeentranslatedintoandvalidatedindierentlanguages
including Italian []. TSK-I is divided into two sub-scales:
evaluating activity avoidance (TSK-AA: a belief that activities
causingpainshouldbeavoided)andharm (TSK-H: a belief
that pain is a sign of bodily damage), respectively. TSK-I is
able to distinguish the fear of movement domain from other
conceptual domains such as pain and functional alteration.
e original version of the TSK-I questionnaire comprises 
items to assess the subjective rating of kinesiophobia [].
Each item has a four-point Likert scale with scoring alter-
natives ranging from “strongly disagree” to “strongly agree.
A total sum is calculated aer inversion of the individual
scores of items , , , and . e total score ranges between
 and . A high TSK-I value indicates a high degree of
kinesiophobia. In the Italian version [],items,,,and
wereexcludedwithatotalscoreofandamaximumscore
for activity avoidance and harm of  and , respectively.
2.2.2. Fatigue. FSS is a scale quantifying fatigue intensity,
which has been used in dierent chronic conditions, such as
multiple sclerosis and systemic lupus erythematosus [], and
shows high internal consistency and validity. FSS comprises
 items with a -point response format that indicates the
degree of agreement with each statement []. MFI- is a -
item self-reporting instrument designed to measure fatigue
[]. It covers the following dimensions: general fatigue (GF),
physical fatigue (PF), mental fatigue (MF), reduced motiva-
tion (RM), and reduced activity (RA). e questionnaire is
constructed with an equal number of questions for each of the
ve suggested dimensions. It has been demonstrated that it is
reliable and valid and has been tested in various conditions,
such as cancer or chronic fatigued patients [].
2.2.3. Pain. NRS is a rapid-to-administrate -point numeric
scale used to roughly measure any kind of pain with a score
ranging from  (no pain) to  (acute pain).
2.2.4. Quality of Life. e Medical Outcome Study -item
Short-Form Health Survey (SF-) is a multipurpose, short
form health survey to evaluate aspects of health most closely
related to quality of life with  questions that measure 
conceptual domains: physical functioning, physical limita-
tion, bodily pain, general health, vitality, social functioning,
emotional limitation, and mental health. e raw scores in
each domain are transformed into  to  scale with higher
scores indicating better quality of life []. e questionnaire
has been translated into Italian and thoroughly validated in
the Italian context [].

with the SPSS soware package for Windows, version ..
e Kolmogorov-Smirnov probability test was used to assess

e Spearman bivariation analysis was conducted in
order to test independent variables related to dependent
ones. Variables assumed as independent included age, sex,
Beighton scores, FSS mean scores, the four subscores of MFI-
, the NRS mean scores, and the SF- in all subforms,
while TSK-I, TSK-AA, and TSK-H scores were considered
dependent variables. Subsequently, a separate multivariate
linear regression analysis was performed for TSK-I, TSK-
AA, and TSK-H as dependent variables, using the Backward
elimination stepwise method and including only indepen-
dent variables that show 𝑃 < 0.250 at the univariate analyses.
e signicance level was set at 𝑃 < 0.05.

4. Discussion
Pain-related fear is a particular characteristic of patients with
musculoskeletal disorders []andplaysanimportantrolein
explaining disability and in transition from acute to chronic
musculoskeletal pain []. From this perspective, kinesio-
phobia (i.e., cognitive fear of movement or reinjury) can
lead to the stopping/reduction of various activities thought

to generate pain with progressive limitation of mobility in
some individuals. e consequent disuse and deconditioning
generatefurtherlossofmuscletone,exibility,andaerobic
capacity, which may explain (bearing in mind the population
under consideration) the transition to the third disease
phase in JHS/EDS-HT [,]symptomprogression.In
this phase, psychological and physical disability is marked
with many patients suering from anxiety, depression, and
somatosensory amplication [] and some obliged to use a
wheelchair.
Overall, the present study, conducted through a ques-
tionnaire-based investigation into  patients, in which there
is a preponderance of females described as characteris-
tic in JHS/EDS-HT even if the mechanism underlying is
unknown [], conrmed the hypothesis that kinesiophobia
is a common symptom in JHS/EDS-HT. We also conrmed
global deterioration of the QoL, moderate/severe bodily pain
and marked fatigue in our patient cohort. Since pain and
fatigue have previously been proposed as relevant factors
determining disability in JHS/EDS-HT [], we tried to
compare the severity of kinesiophobia with the QoL, intensity
of pain and fatigue. Although the bivariate analysis identied
a series of possible correlations (Ta b l e  ), further rening by
multivariate linear regression analysis (Ta b l e  )conrmed
correlation with only general severity of fatigue (i.e., FSS).
Lack of correlation with intensity of pain suggests an intrigu-
ing relationship between kinesiophobia and pathophysiology
of chronic pain in JHS/EDS-HT. In fact, one could expect
that the impact of pain-avoiding strategies is directly linked
to the intensity of perceived pain. is does not hold true in
our sample, where the onset of kinesiophobia is inuenced
by the presence of pain, but not by its severity. erefore, in
JHS/EDS-HT, it is plausible that individual coping strategies
are more relevant than the intensity and/or frequency of the
pain stimulus in generating the psychological and physical
disability related to pain-avoiding behaviours.
BioMed Research International
Conversely, kinesiophobia strongly relates with severity
of fatigue, but not its single components in our sample.
Such a result suggests a direct link between adoption of
pain-avoiding strategies and chronic fatigue. Accordingly, it
could be hypothesized that kinesiophobia may contribute to
the progression and, perhaps, onset of fatigue by bodily disuse
secondary to decreased physical eort. erefore, a three-
phase model of pain-kinesiophobia-fatiguecanbeproposed
by which, in predisposed individuals, repeated musculoskele-
tal traumatism exacerbated by joint hypermobility generates
pain-avoiding strategies, which, in turn, cause/aggravate
fatigue. is mechanism, which may be considered acting in
many chronic pain conditions, appears more pronounced in
JHS/EDS-HT, as hypotonia and hypermobility are primary
features of the disease, and the eects of pain-avoiding
strategies are likely to appear more rapidly and to be more
severe. Recent nding that muscle weakness is associated
with fatigue in EDS is in line with this assumption [].
However, this model of pain-kinesiophobia-fatigue cannot
explain the entire spectrum of clinical variability in JHS/EDS-
HT. In fact, by tracing its natural history, the onset of fatigue
could be independent of joint instability complications and

is study demonstrates once more the urgent need
for evaluating and treating JHS/EDS-HT patients within
multidisciplinary teams comprising a variety of specialists
(who can focus on pain and fatigue) including physiatrists,
physical and occupational therapists, clinical psychologists,
neuropsychologists, pain specialists, and rheumatologists. In
fact, the classic approach of treating JHS/EDS-HT-related
pain based on a combination of physical therapy and adjuvant
pharmacologic support should be associated with and, hope-
fully, substituted, at least in terms of prevention, by regular
physical exercise and cognitive therapies. Various studies
have demonstrated that exercise and tness are benecial in
a biomedical sense of maturation, strengthening, and healing
of bones, tendons, and muscle, while deconditioning refers to
a progressive process of worsening physical tness as reduced
muscular activity []. In JHS/EDS-HT, in particular, doing
moderate and continuous physical activity seems to be useful
in order to keep joint hypermobility and muscle tone, and to
reduce pain, fatigue, and fear of movement.
An individualized, modied, and therapeutic programme
involving a multidisciplinary team is recommended to pre-
vent chronic pain and deconditioning and thereby reduce
suering in JHS/EDS-HT patients.

... Pain catastrophizing and fear-avoidance beliefs have been reported in individuals with hallmark hypermobility and pain [20]. Studies have shown that kinesiophobia is high in this population [37,38], ranging from 75% to 93% in research samples [39,40]. Fear of injury and pain, along with pain catastrophizing, have been reported as barriers to physical activity in patients with hEDS/HSD [33,[40][41][42]. ...
... Studies in other chronic pain populations have reported moderate-to-strong relationships between kinesiophobia and disability [29,81,102], which was not observed in the current study. These results were similar to that of Celletti and colleagues' [39], where scores on the TSK did not relate to measures of quality of life in their hEDS sample. A more recent study also found that TSK scores did not correlate to physical disability scores in hEDS participants [42].These findings may be explained by the nuanced perspective of kinesiophobia in HSD, as described in Schmidt and colleagues' qualitative study [103]. ...
... The finding that fear of falling accounts for significantly more disability than kinesiophobia in this patient population is preliminary and must be replicated. However, these results suggest that issues with joint instability [16], proprioception [39,104], and decreased gait and balance [48] are more strongly related to disability (i.e., increased avoidance of daily activities) than kinesiophobia, and may work in tandem with fear of falling to limit functionality in those with hEDS/HSD. Research has shown that many people who fall, regardless of the resulting level of injury or number of falls, become afraid of falling again, which results in activity avoidance and decreased movement [105]. ...

Purpose: Hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD) are understudied conditions characterized by hallmark hypermobility and chronic pain. Disease manifestations lead to significant disability. Understanding predictors of disability, over and above the univariate construct of pain severity, is necessary to tailor treatment. Thus, the current study examined the impact of the Fear-Avoidance Model [FAM] on disability in hEDS/HSD. Fear of falling was included as a novel fear-avoidance factor impacting disability. Methods: A total of 168 individuals with hEDS/HSD answered a cross-sectional online survey regarding FAM constructs, fear of falling, disability, and clinical-demographic factors. A hierarchical regression analysis was used to assess whether FAM constructs and fear of falling significantly predicted disability, over and above pain severity and age. Results: Pain catastrophizing, anxiety, and fear of falling contributed significant unique predictive relations, above age and average pain severity. Pain severity and fear of falling were the strongest unique predictors of disability. Conclusions: This is the first study to assess the relations among FAM constructs, pain severity, and disability in hEDS/HSD, and introduces fear of falling as a novel fear-avoidance factor specific to this population. Future research should apply these findings towards individualized interventions to improve disability in hEDS/HSD.
... [3][4][5] Pain avoidance strategies can lead to kinesiophobia and reduced physical capacity. 6 Patients also experience a wide range of symptoms, like dysautonomia, gastrointestinal disorders, or breathing difficulties. [7][8][9][10] These symptoms are the cause of a diminished quality of life and have significant psychosocial effect that can lead to anxiety or depression. ...
... One aim of the RP for hEDS patients is the return to a higher level of functional capacity in patients who are often deconditioned due to kinesiophobia for fear of injury. 6,14 In a disease with several manifestations, with one-third of patients experiencing 15-25 symptoms, 40 and with recommendations for global management, 2 an RP (supposed to be global) therefore seems particularly appropriate for the management of these patients. ...
... Rehabilitation for hEDS patients and injury. 6 An increase in fatigue could have been expected at the end of the RP related to the increase in physical activity during the 9 weeks of the RP. On the contrary, there was a significant improvement in fatigue as represented by the total MFI score. ...

Objective: To evaluate the effects of a 9 -week rehabilitation program (RP) for patients with hypermobile Ehlers-Danlos syndrome (hEDS) in the short- and medium-term. Design: Nonrandomized controlled trial with 6 months follow-up SETTING: Outpatient rehabilitation program PARTICIPANTS: A referred sample of 36 hEDS patients were assessed for eligibility, 25 were included, 22 completed the RP and 19 completed the follow-up. Interventions: A 9 -week control period without intervention followed by a 9 week rehabilitation program (RP). Main outcome measure: Functional exercise capacity was used as a primary outcome measure. Balance, kinesiophobia, fatigue, pain, quality of life, anxiety, depression, and hyperventilation were measured as secondary outcomes. Results: No significant change was observed during the 9 -week control period before the RP. There was a significant improvement immediately after the RP for the functional exercise capacity, balance with eyes closed, fatigue and quality of life (P<.05). Even more improvements were found 6 weeks after the end of the RP, and there was still an improvement after 6 months in functional exercise capacity, kinesiophobia, depression, hyperventilation, and some components of the quality of life. Conclusion: This study supports the effectiveness of an RP as a useful management tool for hEDS patients.
... Pediatric Rheumatology (2023) 21:121 by a broad set of symptoms (e.g., heart rate and blood pressure fluctuations) which may mimic anxiety and/or panic attacks. Similarly, poor sleep and/or high levels of fatigue (with 86% of patients endorsing chronic asthenia/ fatigue, [54]) patients with hEDS could be attributed to depression. ...
... These changes are proposed to be linked to heightened interoceptive sensitivity [55,57], which may be tied to the high frequency of anxiety seen in individuals with hEDS [58]. Anxiety has been tied to increased somatosensory amplification, catastrophizing, reduced function, poor sleep [59], and somatic complaints in hEDS, including kinesiophobia [54] and hyperalgesia [60]. This is consistent with existing theories of emotion, which posit that we come to recognize our emotional state by first identifying our internal physical sensations (i.e., James-Lang Theory of Emotion; [61,62]. ...

Background Hypermobile Ehlers-Danlos syndrome (hEDS) is characterized by joint and skin laxity, and often accompanied by chronic pain, dysautonomia, increased distress and, functional limitations. The journey to accurate diagnosis is often prolonged due to unclear etiology of symptoms. This manuscript is a narrative review of the literature on illness uncertainty (IU) in hEDS, highlighting the unique facets of IU in this population, as compared to the broader chronic pain population (given symptom overlap between these two disease groups), that warrant additional investigation. Additionally, we considered the unique challenges associated with IU in the context of the developmental nuances of pediatric populations. Specifically, we aimed to (1) map the extant literature of the IU experience in chronic pain conditions broadly including the pediatric and adult research to identify key concepts related to IU and incorporate potential developmental considerations in IU; (2) delineate and describe the IU experience specifically in patients with hEDS, with the goal of identifying gaps in the literature based on aspects of presentation in hEDS that do and do not differ from the broader chronic pain population; and (3) elucidate the potential areas of adverse impact of IU in both general chronic pain populations, and those with hEDS specifically, to provide actionable areas for future research and clinical care of individuals with hEDS. Results of this review indicate that IU has been well-studied in chronic pain generally, but inadequately evaluated in hEDS specifically. Specific features of hEDS (complexity of the disorder, involvement of multiple bodily systems, contribution of organic pathology) may uniquely contribute to IU in this population. This review suggests that ambiguities surrounding the diagnosis of hEDS, symptom course, and treatment recommendations, along with misdiagnosis, perceived dismissal of symptoms, or attribution of symptoms to mental health concerns might increase risk for IU and related distress in patients. Conclusion Findings from the present review suggest that distinct features of hEDS yield a set of driving factors for IU that may be somewhat different than those faced by patients with chronic pain or other medical conditions. The development of a validated measure of IU to appropriately assess this construct in patients with hEDS is a research priority. In the clinical setting, providers should be attentive to the potentially aversive diagnostic and treatment experiences reported by patients and attempt to provide clear explanations based on the extant knowledge of hEDS, and implement best-practice recommendations for multidisciplinary treatment.
... 2,20 Even simple daily activities can cause shoulder instability, 21,22 leading to further limitations in physical activity. 11,20,23 Despite the high prevalence of shoulder symptoms in hEDS/HSD, there is a lack of consensus on best clinical practices for treatment. Physiotherapists play a crucial role in managing joint instability in this population, 24 but clinical confidence in treating hEDS/HSD is limited. ...

Objective To synthesize the evidence on conservative interventions for shoulder symptoms in hypermobile Ehlers-Danlos Syndrome (hEDS) and hypermobility spectrum disorder (HSD). Data Sources A literature search was conducted using data sources Medline, PEDro, CINAHL, AMED, Elsevier Scopus, and the Cochrane Library from January 1998 to June 2023. Study Selection The review included primary empirical research on adults diagnosed with hEDS or HSD who experienced pain and/or mechanical shoulder symptoms and underwent conservative interventions. Initially, 17,565 studies were identified, which decreased to 9668 after duplicate removal. After title and abstract screening by 2 independent authors, 9630 studies were excluded. The full texts of the remaining 38 were assessed and 34 were excluded, leaving 4 articles for examination. Data Extraction Two authors independently extracted data using a predefined extraction table. Quality assessment used the Joanna Briggs Institute checklists and the Template for Intervention Description and Replication. Data Synthesis The review covered 4 studies with a total of 7 conservative interventions, including exercise programs, kinesiology taping, and elasticized compression orthoses. Standardized mean differences were calculated to determine intervention effects over time. The duration of interventions ranged from 48 hours to 24 weeks, showing positive effect sizes over time in the Western Ontario Shoulder Instability Index, pain levels, improved function in activities of daily living, and isometric and isokinetic strength. Small to negligible effect sizes were found for kinesiophobia during completion of exercise programs. Conclusions Shoulder symptoms in hEDS/HSD are common, yet significant gaps in knowledge remain regarding conservative interventions, preventing optimal evidence-based application for clinicians. Further research is necessary to explore the most effective intervention types, frequencies, dosages, and delivery methods tailored to the specific requirements of this patient population.
... According to Celletti et al., distress, fear of movement and an individuals' coping strategies and behavioral responses to the disease are more likely to predict impairment and quality of life (QoL) rather than intensity of pain [7]. Studies published on HSD/ hEDs indicate that there are no validated outcomes assessment tools that are used for these syndromes. ...

Background: Hypermobile Ehlers-Danlos, (hEDs), and Hypermobile Spectrum Disorder (HSD) are connective tissue diseases that are often clinically indistinguishable. The purpose of this study was to assess 3 outcomes for utility for persons with these diseases in terms of intrarater, interrater reliability and intertrial reliability as well as, the Health Assessment Questionnaire Disability Index (HAQ-DI) an assessment of participants perception of pain and quality of life. To assess change in vital signs and cortisol saliva measures before and after testing. Lastly, compare participants to normal. Methods: Participants attended 3 sessions within 2 weeks. Two trained examiners assessed the reliability of the two-minute walk test, (2MWT), five times sit to stand (5XSTS), grip strength on five participants. There were 10 participants, each completed the self-report, (HAQ-DI). 10 trained assessors evaluated between 1-10 of the participants for the stability of the scores between three trials. Vital signs and rate of perceived exertion (RPE) were assessed pre and post 2MWT; saliva samples were taken. Statistics: For 5 subjects the ICC (2,3) was computed for intra and interrater reliability. For 10 subjects (ICC3,3) intertrial consistency was done. Paired t tests assessed grip strength, change after 2MWT for vital signs, changes in cortisol, and assess the HAQ-DI between administrations. Pearson correlations were completed on HAQ-DI variables, RPE, saliva, and vital signs. Results: All intra and interrater reliability, intertrial agreement was found to be good to excellent. Paired t tests indicated that the HAQ-DI was stable and indicated a moderate perception of pain and reductions in quality of life. These participants showed evidence of impairments relative to normal. There were no differences in saliva cortisol levels. Conclusion: These tests appear to have utility in identification of impairments in bodily systems, activity levels and participation in these participants. Further investigation is necessary in order to establish the optimal management.
... on other hand, making disease assessment is even more difficult and treatment response to a certain treatment modality may be different for each manifestation [31]. physical sequelae experienced by people with ehlers-Danlos Syndrome and Behçet's Syndrome is, in part, amplified with psychological distress and behavioral responses, such as kinesiophobia, a fear of physical movement and activity that collectively contribute to poor Quality of Life (QoL) and further low activity and participation in daily life [32][33][34]. to date, the concurrently presence and management of these two disorders is rare and no cases are reported in literature. ...

Purpose: Narrative Medicine complements the clinically centered approach, which focuses on the analytical and sanitary aspects, with the illness- and disorder- centered models, which deal respectively, with personal coping and social perception of a condition. Hypermobile Ehlers- Danlos Syndrome and Behçet's Disease are two rare multisystemic chronic disease experienced a myriad of clinical symptoms, psychological distress, and poor quality of life. The purpose of this report is to describe application of a multidisclipinary rehabilitation intervention according to the narrative medicine. Case description and intervention: a 35-year-old woman with a 23-year history of Hypermobile Ehlers-Danlos Syndrome and Behçet's Disease was admitted. A multimodal rehabilitation approach was implemented and described through the patient's feelings and expected short-, medium-, and long- terms goals. Moreover, she reported her feeling with periodical interview by her therapist. History patient: The patient was seen for 32 weeks. A decreased pain, as well as improved function was recorded immediately post-intervention. Conclusion: Narration is not just an interpretation of the illness experience, but the result of reshaping the interpretations of the story that both patient and health professional. This discipline provides enrichment of care, especially when combined with rehabilitation in chronic disease, by paying attention to and using even in the therapeutic phase the stories of patients, family and health care personnel, giving the opportunity to define a tailored effectiveness rehabilitation approach at the light of the different points of view of the subjects.
... Different papers have analyzed chronic pain in hEDS and HSD (in the literature before 2017, the diagnosis of hEDS or Joint Hypermobility Syndrome was obtained in many patients that are now expected to receive a diagnosis of hEDS or HSD, using the current criteria and nosology) trying to explain its pathogenesis in order to better address an effective treatment [8][9][10][11][12]. Pain in hEDS and HSD is considered multifactorial, partly related to hypermobility, joint instability, trauma, and previous surgery, and associated with moderate to severe impairment in daily functioning [8,13]. ...

Ehlers–Danlos syndromes are a heterogeneous group of Heritable Connective Tissue Disorders characterized by joint hypermobility, skin hyperextensibility, and tissue fragility. Among the different types, the hypermobile Ehlers–Danlos syndrome is the most frequent and includes generalized joint hypermobility as the major diagnostic criterion. Joint hypermobility in hypermobile Ehlers–Danlos syndrome is often associated with pain that does not always allow the use of effective pain-reducing treatments. Patients with hEDS constantly describe their pain in detail. Eighty-nine patients with hEDS diagnoses were recruited and evaluated. They were asked to describe their pain in writing. The texts were examined through Linguistic Inquiry and Word Count. Correlational analyses were conducted between pain perception and language. A comparison of high/low pain perception and the quality of metaphors was carried out. The results showed that language quality varies depending on how much pain is perceived. The greater the pain is perceived, the lesser the positive effects and the greater the negative effects and dehumanizing metaphors are being used. Moreover, a greater pain seems to be related to a verbal experience of greater isolation and less self-care. In conclusion, the use of metaphors is a useful tool for examining illness experience and may help clinicians in the rehabilitation program.

Ehlers-Danlos syndrome (EDS) can be understood as a heterogeneous group of hereditary disorders of the con-nective tissue, with an abnormal synthesis of collagen, associated with a genetic mutation, leading to alterations in tissues such as skin, ligaments, joints, blood vessels. and other organs. Among the limitations for the physio-therapeutic approach to EDS, the scientific literature to date is small and limited, and the exact clinical manage-ment that can be provided is unknown. The objective for this research was to identify the physiotherapeutic exa-mination, diagnosis and treatment techniques in EDS and the quality of the evidence, through a systematic review 2010-2020. Thirty-three scientific articles were reviewed in which methods and techniques for examination, diag-nosis and treatment were identified, evidencing clinical reasoning for each phase of the approach. In addition, it was found that 15.2% of the articles presented quality of 1++, 6.0% with quality of 1+, another 6.0% with quality of 1-, 12.1% with quality 2++, 21.2% with quality 2+, 3.0% with quality 2-, 27.3% with quality 3 and 9.1% with quality 4 under the criteria of the Scottish Intercollegiate Guidelines Network. In conclusion, regarding the level of evidence of the selected articles, there is a low and high level, since the majority are between 2++ and 3 according to these criteria.

Introduction Kinesiophobia and lymphedema appear to be related conditions, and it is important to understand this relationship, as many of the symptoms and comorbidities presented by individuals with lower limb lymphedema are prevented and treated through movement, thus constituting kinesiophobia as a barrier to intervention. The objective of this study is, therefore, to evaluate and analyze the kinesiophobic beliefs reported by individuals with and without lower limb lymphedema, regarding the agreement, severity and differences found, and to establish levels of kinesiophobia. Methods A case-control study with a total sample of 80 participants (40 with lower limb lymphedema and 40 without) was performed. Both groups (with and without lymphedema) were characterized anthropologically, sociodemographically, and clinically. In the case group, lymphedema was evaluated. Participants in both groups completed the Tampa Scale for Kinesiophobia - 13 items (TSK-13). Results Individuals with lower limb lymphedema had higher TSK-13 scores than their matched group without lymphedema. The items belonging to the activity avoidance subscale had the highest agreement and score in both groups. Differences between groups were mainly established for items belonging to the somatic focus subscale, showing that individuals with lower limb lymphedema have kinesiophobic beliefs related to the perceived severity of their lymphedema. The prevalence of kinesiophobia was increased in both groups, but the severity was mild. Conclusions Considering the apparent tendency of people with lower limb lymphedema to present kinesiophobia and movement-limiting beliefs regarding the condition, greater attention should be paid to its assessment, prevention and treatment from a multidisciplinary and multimodal perspective, which takes into account the multiplicity of factors inherent to kinesiophobia and lymphedema and thus reduce their impact on the management of lymphedema.

Background: Ehlers-Danlos Syndrome (EDS) is a serious chronic condition that leads to diminished quality of life and psychological problems. The current study aimed to systematically reviewed the existing literature on EDS patients' health-related quality of life (HRQoL), calculate mean HRQoL value, and determine the association between demographical and publication-related characteristics with HRQoL. Methods: Four electronic databases were used to identify papers on HRQOL in adults with EDS (Scopus, Medline (by Pubmed), Epistemonikos, and Web of Science). A random-effects meta-analysis was also performed on the 36-item Short Form Survey (SF-36) measure. Results: We contained 37 studies that fulfilled the inclusion criteria. According to the SF-36 meta-analysis, EDS patients and the general population had significant differences in all HRQoL components (p0.01). In EDS patients, the Physical Component Summary (35.34/100) was more seriously impacted than the Mental Component Summary (45.21/100) in these patients. Conclusion: Individuals with EDS have significantly lower HRQoL in all aspects compared to the general population, with the physical component of wellbeing being the most pronounced disparity. Future research should look into the impact of different patient characteristics, evaluate the complications of EDS and their effects on wellbeing, and develop multiple intervention strategies to improve HRQoL.

A 36-item short-form (SF-36) was constructed to survey health status in the Medical Outcomes Study. The SF-36 was designed for use in clinical practice and research, health policy evaluations, and general population surveys. The SF-36 includes one multi-item scale that assesses eight health concepts: 1) limitations in physical activities because of health problems; 2) limitations in social activities because of physical or emotional problems; 3) limitations in usual role activities because of physical health problems; 4) bodily pain; 5) general mental health (psychological distress and well-being); 6) limitations in usual role activities because of emotional problems; 7) vitality (energy and fatigue); and 8) general health perceptions. The survey was constructed for self-administration by persons 14 years of age and older, and for administration by a trained interviewer in person or by telephone. The history of the development of the SF-36, the origin of specific items, and the logic underlying their selection are summarized. The content and features of the SF-36 are compared with the 20-item Medical Outcomes Study short-form.

Hypermobility type Ehlers–Danlos syndrome (HT-EDS) is a relatively frequent, although commonly misdiagnosed variant of Ehlers–Danlos syndrome, mainly characterized by marked joint instability and mild cutaneous involvement. Chronic pain, asthenia, and gastrointestinal and pelvic dysfunction are characteristic additional manifestations. We report on 21 HT-EDS patients selected from a group of 40 subjects with suspected mild hereditary connective tissue disorder. General, mucocutaneous, musculoskeletal, cardiovascular, neurologic, gastrointestinal, urogynecological, and ear–nose–throat abnormalities are investigated systematically and tabulated. Six distinct clinical presentations of HT-EDS are outlined, whose tabulation is a mnemonic for the practicing clinical geneticist in an attempt to diagnose this condition accurately. With detailed clinical records and phenotype comparison among patients of different ages, the natural history of the disorder is defined. Three phases (namely, hypermobility, pain, and stiffness) are delineated based on distinguishing manifestations. A constellation of additional, apparently uncommon abnormalities is also identified, including dolichocolon, dysphonia, and Arnold–Chiari type I malformation. Their further investigation may contribute to an understanding of the pathogenesis of the protean manifestations of HT-EDS, and a more effective approach to the evaluation and management of affected individuals. © 2010 Wiley-Liss, Inc.

To evaluate progression of symptoms and joint mobility in the joint hypermobility syndrome (JHS) in order to identify specific disease pictures by age at presentation. Fifty JHS patients (44 females, 6 males) were evaluated by Beighton score (BS) calculation, and presence/absence and age at onset of 20 key symptoms. Incidence and prevalence rates by age at onset and sex were calculated and compared by chi-square, Fisher's exact test and Mann-Whitney U-test. Relationship between BS and age at examination was evaluated by the Spearman rho correlation. The existence of an age cut-off separating patients with or without a positive BS was analysed by the receiver operating characteristic analysis. Influence of age on the single components of the BS was also investigated. Except for isolated features, the overall clinical presentation was the same between sexes. In the whole sample, statistically significant differences by age at presentation were registered for fatigue, myalgias, muscle cramps, strains/sprains, dislocations, tendon ruptures, tendonitis, gastroesophageal reflux, chronic gastritis, constipation/diarrhoea and abdominal hernias. A clear inverse correlation between age at examination and BS was demonstrated with an age cut-off fixed at 33 years. Among the components of the BS, spine and elbow joints were not significantly influenced by age. This study confirmed the existence of a protean clinical history of JHS which may be exemplified in different phases with distinguishable presentations. The knowledge of the peculiarities of each of them will help the practitioner in recognising and, hopefully, treating this condition.

This article reports on the development and validation of the Italian SF-36 Health Survey using data from seven studies in which an Italian version of the SF-36 was administered to more than 7000 subjects between 1991 and 1995. Empirical findings from a wide array of studies and diseases indicate that the performance of the questionnaire improved as the Italian translation was revised and that it met the standards suggested by the literature in terms of feasibility, psychometric tests, and interpretability. This generally satisfactory picture strengthens the idea that the Italian SF-36 is as valid and reliable as the original instrument and applicable and valid across age, gender, and disease. Empirical evidence from a cross-sectional survey carried out to norm the final version in a representative sample of 2031 individuals confirms the questionnaire’s characteristics in terms of hypothesized constructs and psychometric behavior and gives a better picture of its external validity (i.e., robustness and generalizability) when administered in settings that are very close to real world.

The Ehlers-Danlos syndrome (EDS) is a clinically and genetically heterogeneous group of inherited connective tissue disorders. The six major, well-defined, subtypes are classified according to diagnostic criteria, formalized in the Villefranche revised nosology. Shortly after the publication of these criteria in 1998, a further distinct type of EDS, the tenascin-X (TNX)-deficient type EDS, was reported. The phenotype of this largely unknown type of EDS resembles the phenotype of the classical type of EDS, but its inheritance is autosomal recessive and wound healing is normal; hence, no atrophic scars are present. The clinical diagnosis can be confirmed by the absence of TNX in the serum and by mutation analysis of the TNXB gene. Because the TNX-deficient type EDS is rare and not included in the current diagnostic criteria, this diagnosis is often delayed or even overlooked. Here, we describe four cases which improve the clinical recognition of this type of EDS.

To investigate balance, gait, falls, and fear of falling in patients with the hypermobility type of Ehlers-Danlos syndrome (EDS-HT). Twenty-two women with EDS-HT and 22 sex- and age-matched healthy control subjects participated in the study. Each subject performed the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) and the Tandem Stance test (TS) on an AccuGait force platform to assess balance by center of pressure-based postural sway measures. The GAITRite walkway system was used to record spatial-temporal gait variables during 3 walking conditions (single task, cognitive task, and functional task). Data about fall frequency and circumstances were collected by retrospective recall, and fear of falling was assessed by the modified Falls Efficacy Scale. Compared with healthy subjects, EDS-HT subjects showed significantly impaired balance, reflected by increased sway velocity, mediolateral and anteroposterior sway excursion, and sway area during mCTSIB and TS. Gait velocity, step length, and stride length were significantly smaller during all walking conditions, and a significant dual-task-related decrement was found for gait velocity, step and stride length, and cadence in the EDS-HT subjects compared to the control group. Ninety-five percent of the patients fell during the past year, and some fear of falling was measured. To our knowledge, this study is the first to establish that EDS-HT is associated with balance and gait impairments, increased fall frequency, and poorer balance confidence, implying a decrease in the safety of standing in everyday life situations. Whether these deficits can be improved by appropriate exercise programs needs to be addressed in future research.

Ehlers-Danlos syndrome (EDS) is a clinically and genetically heterogeneous group of inherited connective tissue disorders characterised by joint hypermobility, skin hyperextensibility and tissue fragility. It has recently been shown that muscle weakness occurs frequently in EDS, and that fatigue is a common and clinically important symptom. The aim of this study was to investigate the relationship between fatigue severity and subjective and objective measures of muscle weakness. Furthermore, the predictive value of muscle weakness for fatigue severity was determined, together with that of pain and physical activity. An explorative, cross-sectional, observational study. Thirty EDS patients, recruited from the Dutch patient association, were investigated at the neuromuscular outpatient department of a tertiary referral centre in The Netherlands. Muscle strength measured with manual muscle strength testing and hand-held dynamometry. Self-reported muscle weakness, pain, physical activity levels and fatigue were assessed with standardised questionnaires. Fatigue severity in EDS was significantly correlated with measured and self-reported muscle weakness (r=-0.408 for manual muscle strength, r=0.461 for hand-held dynamometry and r=0.603 for self-reported muscle weakness). Both muscle weakness and pain severity were significant predictors of fatigue severity in a multiple regression analysis. The results suggest a positive and direct relationship between fatigue severity and muscle weakness in EDS. Future research should focus on the relationship between fatigue, muscle weakness and objectively measured physical activity, preferably in a larger cohort of EDS patients.
