introduction
Flexibility is the ability to move a joint through its full range of motion (ROM)
with control. A lack of mobility in one joint can lead to injuries and pain along the
kinetic chain [1]. By increasing ROM, we may be able to enhance performance
and reduce the risk of injury, and athletes should possess a level of exibility
that is appropriate for their chosen activities [2]. Moreover, increased ROM
leads to improvements in vertical jumps [3]. Currently, there are many methods
available to acutely increase ROM, one of which is medical ossing, also
known as voodoo ossing [4]. It is assumed that the possible mechanisms of
improvements in ankle ROM due to ossing are connected with fascial shearing
and blood-ow restriction. Perhaps, this is a similar process to that of blood-ow
restriction training through which increased amounts of growth hormones and
catecholamine responses arise, increasing muscle forces and contractility and
the eiciency of excitation-contraction coupling in the muscles [5, 6]. Fascia
is a tough connective tissue that is present throughout the body in a three-
dimensional web from head to toe. Fasciae are ubiquitous, surrounding every
muscle, bone, nerve, blood vessel and organ at the cellular level. Generally, the
fascial system provides support, stability and cushioning. It is also important
for locomotion and dynamic exibility due to muscle involvement, and it is
considered the main contributor to proprioception in the body [7, 8]. Fasciae play
the main role in movement coordination and muscle interaction. An insuicient
amount of exible fasciae can lead to weakened muscles and poor muscular
biomechanics, which lead to a decreased ROM, altered structural alignment
and reduced endurance and motor coordination [9, 10]. Shearing caused by
rubber bands might decrease the stiness of the fascia, the main eect of which
is an increase in ROM.
As mentioned above, ossing may have similar mechanisms to ischemic
preconditioning/blood-ow occlusion/restriction training. In addition to the
hormonal response it yields, ischemic preconditioning has been shown to
improve muscle contraction eiciency, possibly by increasing muscle forces
and contractility [11], and/or to improve the quality of excitation-contraction
coupling [12]. Flossing can be applied to any joint or muscle in the body. However,
because the ankle joint is important for walking, jumping and landing, most of
the previous studies have focused on the ankle. The ankle is a complex part of
the human body [13]. Proper biomechanical function of the ankle is required
for the lower extremities to function normally [14]. Changes in ROM can lead
to many dysfunctions, both in normal daily living, as ankle dorsiexion (DF) is
required during walking [15], and during sport activities, as DF is an important
strategy used to absorb shock when landing after a jump [16, 17]; limitations
in the movement of the ankle lead to restricted knee exion displacement
and knee valgus displacement during landing and squatting. All these issues
may contribute to increased anterior cruciate ligament (ACL) injury risk,
patellofemoral pain and other lower-limb injuries [1722].
There is a limited amount of research on ossing, and no review articles have
been conducted. Kiefer et al. [23] assessed the eect of ossing on glenohumeral
exion in child’s posture. The results showed that there were no signicant
dierences between the ossing and control groups; however, participants
indicated more signicantly perceived benets from the intervention in terms
of mobility. Moreover, the glenohumeral joint is considered diicult to wrap with
tape, unlike the ankle, which is the main point of interest in this eld.

Although an eect of ossing has been documented, it has not been determi-
ned how large impact can be expected with this method; therefore, the aim of
this study was to conduct a meta-analysis on the eects of ossing on aspects
of performance.
material and methods
search strategies
The review included studies that examined the eects of ossing on the ankle
range of motion. The articles in the Scopus, PubMed, PEDro and Google Scholar
databases were searched. The search took place in November 2019, and the
results were not restricted by dates. The databases were searched by using
the following keywords: range of motion, ossband, mobility bands, vascular
occlusion, ossing bands, compression, voodoo oss, and tack oss. These key
words were used individually and/or in combination.
stu dy selection
The inclusion criteria for the studies in this review were as follows: the study
contained a research question regarding the inuence of ossing on the ankle
range of motion; the ROM test was performed with the standard methodology,
with the results reported in cm; and the study was published in English. The
exclusion criteria were the text not in English, poor methodological design
or measured parameters.
quali tative comparison
Qualitative analyses were performed using RevMan version 5.3 (Copenhagen).
Weighted means was used to calculate the ossing eect among dierent
studies and e. Hedges’ g was consequently chosen for eect size. I2 was used
to assess heterogeneity.
results
The search process is presented in Figure 1. In total, 5503 records were
identied with search keywords in the Scopus database, and 132 records were
identied from other sources. After the duplicate articles were removed, a
total of 5600 articles remained. After the abstracts were screened, 28 articles
remained, and 22 articles were excluded because they were not suitable for
a systematic review. The full texts of six articles were used to determine their
eligibility (Supplementary material 1), and two of them were not suitable for
qualitative comparison with other studies. In total, 4 records were included in
the meta-analysis. In total, those 4 documents involved 145 participants, where
all studies used weight-bearing lunge test (WLBT). One article was missing a
control group because it used a crossover design. The remaining study [24]
used the contralateral leg, which did not undergo the ossing treatment, for
comparison, or the participants attended another session to obtain control
group results.
Table 1 and Figure 2 show the main results of the included studies, where
all authors of these studies concluded that ossing increases the ankle range
of motion. Table 2 and Figure 3 show the reported changes in the included
studies. The weighted mean dierence in ROM after treatment was 1.20 cm

(Hedge’s g = 0.31, CI [0.086, 0.529], Z = 2.719, p < 0.01, I2 = 89%). The
control groups did not show any dierences between pre and post treatment.
The same result was conrmed in the two other studies, where one was a
single case and the other reported the increased ROM in degrees [25, 26]. The
jump performance increase has been reported in two studies performed by
Driller and one study performed by Mills [24, 27, 28]. In his rst study Driller
measured jump height and velocity which makes it incomparable with the
other two studies, where peak force was measured during Counter Movement
Jump (CMJ). Results have shown 4 cm improvement in the jump height and
0.15 (m.s-1) jump velocity improvement [24]. In another Driller study, the
ossing impact on CMJ peak force was measured after application. Results
have shown increasing of the peak force in the following order: 69 ± 67N after
5 minutes (d = 0.16), 56 ± 70N after 15 minutes (d = 0.13), 135 ± 148N after
30 minutes (d = 0.32) and 89 ± 101N after 45 minutes (d = 0.21) [27]. Mills
also compared CMJ peak force pre and post values after 5 and 30 minutes,
which resulted in 90 ±117N (d = 0.28 ±0.45) improvement after 5 minutes
after oss application, and -37 ±77N (d =- 0.12 ±0.30). Overall, those results
showed a benecial impact of ossing application on the jump performance.

discussion
In the rst quantitative systematic review of the ossing eect on the ankle
range of motion, the evidence shows a small benecial eect of ossing.
Some of those papers reported few indicators; for instance, Driller and Mills
assessed countermovement jumps (CMJs) after ossing, and in both studies,
the outcomes yielded positive results. Based on these results, it can be assumed
that ossing improves jump performance; however, more research needs to
be conducted. Moreover, ossing can be applied to any part of the body that
has fascia, but for now, most of the articles have focused on the ankle. This
focus should be broadened, and new parts of the body should be explored to
discover the potential of ossing. A study made by Hodeaux was assessed the
impact of ossing application on the elbow ROM [29], and in another study
ossing was applied to the glenohumeral joint to assess its eiciency [23].
Since improvement in the ankle ROM at the 0.6 cm level was considered large
[30], the change in dorsiexion measured with WBT at the 1.2 cm level can
be considered a large increase in ankle mobility. On the other hand, the most
signicant limitation of this study is the dierences in studies participants:
in two studies, they were recreational athletes; in another study, they were
professional athletes; and in the last study, the participants were individuals
free from lower extremity injuries for 3 months. However, we can assume that
ossing is benecial to participants at dierent performance levels.
Driller et al. suggested the benecial inuence of ossing on the ankle ROM and
jump performance. In his rst article, he assessed 52 recreational athletes by
using the WLBT, measuring ankle DF and plantar exion (PF) with a goniometer
and measuring single vertical jump height and velocity with a Gymaware
device. The results showed a signicant improvement in all test measures pre-
to postintervention (p < 0.01) [24]. In his second study, 69 recreational athletes
performed the WBLT, countermovement jump (CMJ) and a 15 m sprint test
(SPRINT) before and up to 45 minutes after the application of the ossband to
both ankles (n = 38), and the control group did not receive ossing (n = 31). There
were signicant dierences (p > 0.05) between the FLOSS and CON groups in
the results for the WBLT, CMJ and 15 m sprint [27]. Stevenson et al. measured
the inuence of ossing in 5 male recreational athletes. They used a goniometer
and the WBLT to obtain the results, which showed that DF signicantly improved
in the ossing group compared with the control group [26].
A group of scientists from New Zealand determined the eect of ossing
in 14 professional male rugby union athletes (mean ± SD: age; 23.9 ± 2.7)
[28]. They applied ossing for two minutes to both ankles and performed the
same measurements without ossing on a separate day for the control data.
The WBLT, CMJ and 20-meter sprint were performed, and the outcomes were
assessed 5 minutes after and 30 minutes after application. The results showed
a small but non-signicant (p > 0.05) benet in the FLOSS group compared
with the CON group for the CMJ at 5 minutes post-intervention (d = 0.28)
and for sprinting for 10 meters (d = -0.45) and 15 meters (d = -0.24) at 30
minutes after the intervention [28]. Therefore, the results of ossing on jump
performance should be more clearly evaluated.
In a study performed by Reid et al. [30], improvement in the ankle ROM was
measured by the mobilization-with-movement (MWM) technique on talocrural
joints. Dorsiexion was assessed using a weight-bearing lunge test. They used

a crossover design with randomized allocation to either a sham mobilization
group or the MWM technique group. The results showed that the change in
dorsiexion following the MWM technique (0.63 ± 0.89 cm) was signicantly
larger (p = 0.02) than the change following the sham technique (0.18 ± 0.35
cm). Vicenzino et al. [31] measured the changes in the posterior talar glide and
dorsiexion of the ankle after mobilization with movement (MWM) in individuals
with recurrent ankle sprains. The results showed that both the weight-bearing
and non-weight-bearing MWMs signicantly improved dorsiexion by 26%
(p < 0.17) in a WBLT test. Dorsiexion before treatment was 4.2 ± 1.6 cm for
weight-bearing WMWs and 4.3 ± 1.9 cm for non-weight-bearing MWMs, and
those after treatment were 4.8 ± 1.5 cm for WB_MWMs and 4.8 ± 1.5 cm for
NWB_MWMs, which yielded 0.6 cm of improvement for WB WMWs and 0.5 cm
of improvement for NWB_WMWs.
Weight Bearing Lunge Test (WBLT) is a very reliable test to measure the
dorsiexion (DF) range of movement in the ankle joint [32]. It does not require
any tools, and the methodology is not complicated; therefore, it is a popular
choice among researchers to assess the ankle ROM.
conclusions
After analyzing all the results and comparing ossing to other methods, it
can be assumed that ossing is a useful method to acutely increase ROM.
It can be used by physiotherapists during rehabilitation for individuals with
ankle ROM limitations and athletes as a part of warm-up, especially before
exercises that require a full ankle ROM, i.e., squats, CMJ. Moreover, it seems
to be a good technique for individuals who participate in sports that involve
jumping, e.g., volleyball and basketball; two studies proved that ossing could
improve jump performance.

Flossing eect on ankle ROM and jump performance
Balt J Health Phys Act. 2020;12(2):19-26
... While there have been several review papers published about the effects of the more common techniques such as stretching or foam rolling on, for example, the range of motion (Behm et al., 2016;Wilke et al., 2020) or performance parameters (Behm and Wilke, 2019;Konrad et al., 2021), no such overview exists for the effects of flossing. To date, two reviews with similar specific research questions have been published, i.e., if flossing of the ankle or calf can increase the dorsiflexion range of motion (Kielur and Powden, 2020;Pisz et al., 2020) or jump performance (Pisz et al., 2020). Although these reviews investigated the range of motion of one joint (ankle), other effects of flossing, e.g., an increase in strength, increased recovery, or decrease in pain caused by various diseases or injuries, were not covered by these reviews. ...

There is a belief that tissue flossing can improve range of motion or performance, speed up recovery, and decrease pain caused by various diseases or injuries. As a result, many therapists, patients, and athletes are now using this technique. Consequently, in the last five years, a number of studies have addressed these assumptions. The purpose of this scoping review is to introduce the application of a floss band and to summarize the existing evidence for the effect of floss band treatment on range of motion, performance, recovery, and pain (due to disease or injuries). A further goal is to suggest what needs to be addressed in future studies. The online search was performed in the PubMed, Scopus, and Web of Science databases. Any studies dealing with the effects of a floss band treatment on range of motion, performance, recovery, or pain parameters in any population (e.g. patients, athletes) were included in this review. Twenty-four studies met the inclusion criteria, with a total of 513 participants. The included studies revealed that there is evidence that a single floss band treatment is able to increase the range of motion of the related joint and can positively affect jumping and strength performance. However, these findings show only small to moderate effect sizes. Although not yet clearly understood, a possible mechanism for such changes in range of motion or performance is likely due to changed neuromuscular function, rather than changed mechanical properties of the muscle (e.g. stiffness). All in all, there is a need to conduct long-term studies about the effects of flossing treatment on range of motion and performance (e.g. strength or jumping parameters) and its related mechanism (e.g. pain tolerance). There is weak evidence that flossing can be of value for pain relief in the treatment of certain diseases, and for speeding up recovery after exercise. Moreover, there is weak evidence that flossing might have a superior conditioning (warm-up) effect compared to stretching when the goal is to improve range of motion or certain aspects of muscle strength, while no such superior effect has been reported when compared to foam rolling.
... To date, two reviews have been published on the effectiveness of using ankle flossing to improve dorsiflexion amplitude (Kielur & Powden, 2020;Pisz et al., 2020) or jump performance (Pisz et al., 2020). Therefore, although there is research on the range of motion in the ankle joint after using medical flossing, there are no publications on other effects of flossing, such as increased muscle strength, improved recovery time or decreased pain caused by various pathologies. ...

Although there are multiple published reviews about the effects of the most common techniques, such as stretching or the use of foam roller on the range of motion (Behm et al., 2016; Wilke et al., 2020) or performance parameters (Behm & Wilke, 2019; Konrad et al., 2021), there is no analysis on the effects of medical flossing. To date, two reviews have been publishedabout effectiveness of using ankle flossing to improve dorsiflexion amplitude or jump performance (Pisz et al., 2020; Kielur & Powden, 2020). This study aimed to investigate the effectiveness of medical flossing added to routine treatment in patients with epicondylitis, compared to conventional physiotherapy treatment. The study included 6 subjects who showed localized pain in the area of the lateral epicondyle exacerbated with the Cozen test. The other criteria for selecting patients were the duration of the symptoms, less than 3 months from the onset of the disease and pain intensity more than 5 on the Visual Analog scale.To monitor the evolution of the subjects involved, we used a visual analog pain scale to assess the intensity of pain at different times during the application of therapy, before and after the end of the treatment. Another tool used to measure the degree of pain and dysfunction was the PRTEE Questionnaire (Patient-Rated Tennis Elbow Evaluation). The rehabilitation program took place between August and September 2021, for 30 days, with afrequency of 3 times per week. 6 patients with lateral epicondylitis were included and medical flossing was used only in the case of 3 patients at each therapy session. The differences between groups at the time of the initial assessment, in terms of pain intensity were statistically insignificant (p=0.288, p>0.05). The results obtained in terms of decreasing pain were in favor of the use of medical flossing as an adjuvant method in specific pain existing in lateral epicondylitis. Although in both groups there was a decrease in pain after 4 weeks of treatment, the intervention group recorded significant reduced values compared to the control group (p=0.024; p<0.05). Regarding PRTEE Functional Score, at the final assesment there was a decrease in both groups, which means the functional condition of the patients has improved.
... However, there was a significant difference of DFROM between the pre-and post-tests in the flossband group [15,20]. Systematic evidence showed that flossband treatment is a useful method to acutely increase the effects of ankle ROM, compared to other methods [30]. Only one out of 19 individual studies wrapped flossband on the upper arm, and the results showed that shoulder flexion was significantly improved [20]. ...

Flossband, as a novel and effective tissue flossing technique, is becoming increasingly popular in the field of athletic training, sports injury prevention, and rehabilitation. The purpose of this literature review is to summarize updated evidence about the effects of flossband application on joint range of motion (ROM), pain, muscle tightness, strength, and physical functional performance as well as identify research gaps for future study. Google Scholar, PubMed, EBSCO, and Web of Science were used to search related articles. The keywords of floss bands, flossbands, floss band, tissue flossing, flossing band, voodoo floss band, voodoo floss bands, track floss, rock floss, life floss band, and Rogue voodoo floss were used to extract target articles. English journal articles, full-text available, and content related to outcome measures were included. Conference abstracts, books, case studies, guideline reviews were omitted. 23 full-text journal articles were included for further qualitative analysis after removing duplicates and deleting articles that violate the screening criterion. Flossband application on limbs, soft tissue, or joints with about 50% flossing tension or 150 mmHg wrapping pressure could have small to medium effects on the parameters of ROM, muscle stiffness, muscle strength, and physical function performance, and large effects on pain management. Most previous studies were mainly focused on the acute effect of flossband application on peripheral joints or soft tissues in healthy and active participants or well-trained athletes. Therefore, for future studies, more evidence is needed on the benefits of long-term flossband trunk application and concerning patients with various diseases.

Context: Given the relatively novel technique of tissue flossing is currently lacking in the research literature despite some positive findings in preliminary studies, the modality clearly requires further research. Current evidence suggests that band flossing results in performance improvements and may also be an effective method in injury prevention. Objective: Previous research has shown that tissue flossing may result in increased ankle range of motion, jump, and sprinting performance in recreational athletes. The present study aims to extend on this research, within an elite athlete sample. Design: Counterbalanced, cross-over design with experimental and control trials, separated by 1 week. Setting: University laboratory. Participants: Fourteen professional male rugby union athletes (mean [SD]: age 23.9 [2.7] y). Intervention: Application of a floss band to both ankles (FLOSS) for 2 minutes or without flossing of the ankle joints (CON) on 2 separate occasions. Main Outcome Measures: A weight-bearing lunge test, a countermovement jump test, and a 20-m sprint test at pre and at 5 and 30 minutes post application of the floss band or control. Results: There were no statistically significant interactions between treatment (FLOSS/CON) and time for any of the measured variables (P > .05). Effect size analysis revealed small benefits for FLOSS in comparison with CON for countermovement performance 5 minutes post (d = 0.28) and for 10-m (d = -0.45) and 15-m (d = -0.24) sprint time 30 minutes post. Conclusion: Findings from the current study suggest minimal benefits of tissue flossing when applied to the ankle joint in elite athletes for up to 30 minutes following their application.

Background: The frequent and intensive training and performance of pre-professional ballet dancers and sportspersons is offered at a time when young ballet dancers and young athletes may be vulnerable to injury due to the progress through adolescence and growth spurts. Hypothesis: There are changes in range of motion during the progress through adolescence and growth periods in dancers and sportspersons. These changes in ROM can be linked to the increase of injury. Objectives: The primary aim of this systematic review is to determine whether there are changes in ROM during the progress through adolescence and growth spurts in dancers and sportspersons. The secondary aim is to determine whether these changes can predict the risk of injuries for adolescent dancers and sportspersons. Search strategy: Pubmed, Cochrane Register of Controlled Trails (CENTRAL), Cochrane Database of Systematic Reviews (CDSR), EBSCO Host databases: CINAHL Plus, MEDLINE, SPORTDiscus, Embase were searched using MeSH terms. Manual search in the Journal of Dance Medicine and Science and screening of the reference lists of identified studies and reviews was conducted. Selection criteria: Studies included adolescent dancers and sportspersons, aged 8–18, both sexes, growth spurt related to changes in ROM and injury incidence. Data collection and analysis: Search strategy was performed in the flow diagram of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two reviewers independently appraised each included study using Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) for methodological quality of the included studies. For data extraction, the following information was systematically extracted: first author and year of publication, study design, participants (sample size of mean age), age, maturation (if assessed), intervention, outcome(s), and some notes of each study. For evaluation of the risk of bias and precision the Research Triangle Institute Item Bank (RTI-IB) is included. Main results: Seven observational studies met the inclusion criteria of this current review. The results of this review suggest that there are changes in ROM during the progress through adolescence and growth spurts in dancers and sportspersons. These changes may lead to an increase in injury incidence. Conclusion: There is evidence linking to changes in ROM during the progress through adolescence and growth spurts in dancers and sportspersons. These changes in ROM may be related to injury incidence.

Injuries to the ankle are common in children. We investigated whether decreased dorsiflexion predisposes to such fractures and sprains. Passive dorsiflexion in children with ankle injuries was compared with that in a control group of patients with a normal ankle. The uninjured side was examined to determine flexibility in those patients with ankle injuries. In 82, the mean dorsiflexion was 5.7° with the knee extended and 11.2° with the knee flexed. In 85 controls, the mean dorsiflexion was 12.8° with the knee extended and 21.5° with the knee flexed (p < 0.001, Student’s t-test). There was a strong association between decreased ankle dorsiflexion and injury in children. A flexible triceps surae appeared to absorb energy and protect the bone and ligaments, while stiffness predisposed to injury. We suggest that children with tight calf muscles should undergo a regimen of stretching exercises to improve their flexibility.

Objectives: Previous results from our laboratory suggest that band flossing results in increased ankle range of motion (ROM) and jump performance 5-min following application. However, the time-course of such benefits is yet to be examined. Design: Parallel group design. Setting: University laboratory. Participants: 69 recreational athletes (32 male/37 female). Main outcome measures: Participants performed a weight-bearing lunge test (WBLT), a counter-movement jump (CMJ) and a 15 m sprint test (SPRINT) pre and up to 45-min post application of a floss band to both ankles (FLOSS) or without flossing of the ankle joints (CON). Results: There was a significant intervention × time interaction in favour of FLOSS when compared to CON for the WBLT (p < 0.05). These results were associated with trivial to small effect sizes at all time points. Small, but non-significant (p > 0.05) benefits were seen for FLOSS when compared to CON for CMJ force (mean ± 90%CI: 89 ± 101 N) and 15 m SPRINT times (-0.06 ± 0.04 s) at 45-min post. Conclusion: There is a trend towards a benefit for the use of floss bands applied to the ankle joint to improve ROM, jump and sprint performance in recreational athletes for up to 45-min following their application.

Even though adaption of the Voodoo Floss Band is gaining momentum, evidence based literature on its effectiveness remains sparse. The purpose of this quantitative observational design study was to investigate the effects of the Voodoo Floss Band on soft-tissue flexibility and perception of movement. A repeated measures ANOVA with between subjects factor demonstrated both groups significantly improved GH flexion range of motion from pretest to posttest but there was not a statistically significant difference between the groups. Perceptions of flexibility increased more for the Voodoo Floss Band group demonstrating a psychological increase in GH flexion, but not a physical increase.

Objectives: Tissue compression and partial vascular occlusion using band flossing results in re-perfusion of blood to the muscle tissue that may ultimately increase range of motion (ROM) and reduce risk of injury. However, the effect of band flossing on ankle ROM and jump performance is yet to be evaluated. Design: In a crossover design, participants performed a number of tests pre and post the application of a floss band to one ankle (FLOSS), with the contralateral ankle acting as the control (CON). Setting: University laboratory. Participants: 52 recreational athletes (29 male/23 female). Main outcome measures: Pre and post measures included a weight-bearing lunge test (WLBT), ankle dorsiflexion (DF) and plantarflexion (PF) ROM, and single leg vertical jump height and velocity. Results: FLOSS resulted in significant enhancements in all test measures pre to post (p < 0.01), with no significant changes pre to post for CON (p > 0.05). All pre to post changes were associated with small effect sizes for FLOSS compared to CON. Conclusion: Floss bands applied to the ankle increase dorsiflexion and plantarflexion ROM and improve single-leg jump performance in recreational athletes. The results from this study suggest that floss bands may be used for injury prevention and athletic performance.

Background: Achilles tendinopathy is an overuse injury that often affects individuals engaged in recreational or competitive level activity. Although most patients experience satisfactory results with therapy, a substantial portion fail to respond to traditional treatment. The purpose of this case study is to describe the successful use of compression tack and flossing (CTF) with lacrosse ball massage (LBM) in the treatment of an adolescent athlete with Achilles tendinopathy who had failed to respond to traditional treatment. Case description: The patient was a 14-year old female diagnosed with chronic Achilles tendinopathy. She presented with 8/10 left posterior ankle pain during activity and scored 66/80 on the Lower Extremity Functional Scale (LEFS). After six weeks of PT consisting of eccentric exercise, proprioceptive training, and iontophoresis, the patient continued to report pain during sport and no significant improvements on the LEFS. With traditional PT failing to resolve symptoms, the patient was treated with CTF and LBM. Outcomes: The outcomes of interest were the LEFS and the ability to participate in sport without pain. After only two sessions focusing on CTF and LBM, she had 0/10 pain during sport and scored a 79/80 on the LEFS. Patient was discharged to continue with a home exercise program consisting of CTF and LBM, and eccentric exercise. Discussion: The patient's outcomes significantly improved after CTF and LBM was added to eccentric exercise. These results suggest that this intervention may be a viable adjunct treatment for Achilles tendinopathy; however further research, including controlled clinical trials and long-term outcome data, are warranted.

Flexibility is a component of fitness that must be assessed in the context of the demands imposed by a chosen physical activity. Furthermore, clinicians should recognize that flexibility demands are sometimes position or event specific (e.g., the multievent track athlete). As evidence-based practitioners, we must continually seek to improve the utility of the methods used to assess flexibility and the effectiveness of the methods used to improve it.
