Introduction
Stroke persists as a leading cause of hospitalization
due to central nervous system disorders across the
world, posing significant healthcare challenges.
Although advancements in medical practice have
reportedly diminished both fatality and incidence rates
of stroke (Brown J. A., 2006), its prevalence,
associated mortality, and the profound risk of lasting
disability in survivors render it a considerable concern

at the turn of the millennium. The World Health
Organization delineates stroke as the rapid onset of a
focal or global neurological deficit of presumable
vascular origin, which endures for no less than 24
hours or culminates in death. This definition
encompasses spontaneous subarachnoid
hemorrhages but excludes transient ischemic attacks
and other forms of hematomas.
For individuals who have weathered the immediate
consequences of a stroke, their prospective recovery
and the prospect of sustained independence become
paramount. These concerns extend to their families
and healthcare providers, especially physiotherapists,
who are directly involved in their care. The significance
of outcome studies is accentuated in the
contemporary context of cost-managed healthcare
systems where such data critically inform treatment
guidelines and policymaking.
Studies concerning the functional outcomes of
ischemic and hemorrhagic strokes highlight that
survival, impairment, disability, and quality of life are
key variables in patient recovery. Research by Frank &
Silver, (1984) has underscored the importance of
analyzing early mortality, pointing to a bimodal
distribution with peaks in the first week due to brain
herniation and in subsequent weeks due to
complications from immobility. Factors such as age,
hypertension, comorbidities, blood glucose levels,
hemorrhage size, and ventricular spread have been
repeatedly identified as predictors of mortality.
Notably, early mortality is especially high for
hemorrhagic stroke patients.
Long-term survival analyses suggest better outcomes
for those who survive beyond the acute phase of a
hemorrhagic stroke, warranting strong advocacy for
intensive rehabilitation efforts. Studies like those of
Wei et al. (2024) have demonstrated positive
rehabilitation outcomes, particularly for subarachnoid
hemorrhage patients, with a significant portion
achieving sufficient independence to return home.
Despite the serious and often immediate implications
of stroke, certain studies indicate no significant
difference in long-term functional independence
between ischemic and hemorrhagic stroke survivors,
while others suggest a somewhat faster functional
gain in hemorrhagic stroke patients. The
heterogeneous nature of stroke outcomes indicates
that while some recovery predictors are well-
established, the individual patient's trajectory can be
difficult to predict, necessitating a personalized
approach to rehabilitation planning.
Existing literature presents a spectrum of findings.
Ikramuddin and colleagues (2019) found no significant
correlation between age, blood pressure at the time of
admission, and the interval between stroke onset and
hospital admission with functional improvement post-
stroke. Conversely, Kuriakose & Xiao (2020) reported
superior discharge outcomes for men with left-sided
cerebrovascular events compared to those affected
on the right side. Novack and colleagues (1984)
highlighted the temporal relationship between the
onset of stroke and admission to a rehabilitation
facility as an influential factor in patient outcomes.
Petty et al. (2000) identified discrepancies in
recurrence rates and post-stroke functionality among
different ischemic stroke subtypes, particularly noting
the lower survival rates for strokes originating from
cardiac embolism.
Other investigations (Salvadori et al., 2020), have
explored the potential variance in functional recovery
contingent on the nature of the strokehemorrhagic
versus ischemicyielding mixed outcomes. Kelly
(2003) observed admission Functional Independence
Measure (FIM) score discrepancies between patients
with cerebral infarction and those with intracranial
hemorrhage. Kojic and colleagues (2009) underlined
the role of hematoma size and ventricular rupture in
determining mortality in hemorrhagic stroke cases,
advocating for assertive rehabilitation to foster
independence in survivors.
Considering these divergent findings, the precise
measurement of functional outcomes is crucial. The
Motor Assessment Scale (MAS) is an established tools
that have been widely utilized to gauge rehabilitation
progress. It’s recognized for its reliability in providing
objective results without the necessity of costly
equipment (Carr & Shepherd, 1985).
The disparities in stroke outcomes necessitate further
investigation. Therefore, this study is designed to
explore the functional outcomes of ischemic versus
hemorrhagic stroke during the acute phase, utilizing
the MAS and FIM as evaluative instruments. Through
this research, we aim to contribute to a more
discerning understanding of post-stroke recovery,
thereby justifying the need for a differentiated
approach in physiotherapy treatment strategies and
healthcare policies.

Methodology
This research employed a comparative cohort design
to examine and contrast the functional outcomes of
physiotherapy in patients with ischemic versus
hemorrhagic stroke. The participants were randomly
differentiated into two groups according to the nature
of their strokes as confirmed by computed
tomography (CT): Ischemic Stroke Group (ISG) and
Hemorrhagic Stroke Group (HSG).
The study's participant pool was carefully curated.
Individuals were included if they had experienced their
first stroke, evidenced by CT scans indicative of
ischemic or hemorrhagic pathology. Candidates were
required to be over the age of 35, with a minimal
Glasgow Coma Scale score of 5 to ensure
consciousness and potential for participation.
Neurological impairment was a necessity for
inclusion, specifically the presence of hemiplegia, and
candidates had to be accessible for enrollment within
one week following their stroke. Exclusion criteria were
put in place to ensure the homogeneity of the study
sample and the reliability of the outcome measures.
Individuals with hemorrhage due to trauma or tumor,
strokes impacting the cerebellum, brainstem, or
causing subarachnoid hemorrhage, were not
considered. Furthermore, severe cognitive
impairments or the presence of severe pre-existing
disabilities that could influence the rehabilitation
outcomes led to exclusion from the study.
All study participants underwent a standardized four-
week physiotherapy regimen based on the Motor
Relearning Programme (MRP). The MRP is a
comprehensive rehabilitation approach tailored to
stroke recovery, advocating for the relearning of motor
skills through repetitive, functional tasks that mimic
daily activities. It is a patient-centered protocol that
involves goal setting, task breakdown, and practice of
movements, such as transfers, walking, and upper
limb function, within a real-life context. The MRP was
delivered by skilled physiotherapists who were trained
in the method.
The study utilized the Motor Assessment Scale (MAS)
and the Functional Independence Measure (FIM) to
gauge recovery progress. The MAS, developed by Carr
and Shepherd (1985), is a brief, reliable scale that
evaluates essential motor functions without the need
for costly equipment. Studies by Poole et al. (1988)
established its concurrent validity with the Fugl-Meyer
scale, while Dean and Mackey (1992), recognized its
utility in documenting rehabilitation outcomes. The
FIM, widely used since 1987, addresses the need for
standardized disability and rehabilitation outcome
data. Research by Dodds et al. (1993), Donaghy &
Wass (1998) and Beninato et al. (2006) highlighted
FIM’s value as a prognostic indicator and functional
measure in stroke rehabilitation, respectively.
Comparisons with other indices like the Barthel Index
confirmed FIM’s superior reliability and validity, with a
study by Kidd et al. (1995) rating it as more valid for
disability assessment and found FIM to possess high
interrater reliability, especially in motor tasks. The FIM
was selected for this study due to its extensive
adoption, ease of scoring, and proven reliability and
validity, enhancing communication between
healthcare settings and contributing to ongoing efforts
to improve treatment outcomes for this significantly
disabling condition.
Following the acquisition of written informed consent,
baseline data including medical history, demographic
details, presence of hypertension, and the date of
stroke onset were meticulously recorded for each
subject. Initial evaluations using the MAS and FIM
scales were conducted to establish a starting point for
subsequent comparisons. Progress assessments
were then scheduled at the end of each week for the
entire duration of the physiotherapy program, resulting
in a comprehensive set of data points across the four
weeks of intervention.
Result
This research investigated the recovery patterns of two
cohorts of stroke patients by tracking the outcome
scores after a four-week MRP programme. Descriptive
statistics were used to describe the demographic data
of participants, offering a fundamental
comprehension of the sample. Following that, paired
and independent t-tests were used to detect
differences within each patient group over time and
between the two groups, respectively. This facilitated
the measurement of the impact of the MRP on patient
outcomes.
This research aimed to examine the functional results
during the acute stage of two types of strokes:
ischemic and hemorrhagic. It comprised 38
participants, 19 in each group. In the Ischemic Stroke
Group, there were fourteen men (73.7%) and five
females (26.3%); in the Hemorrhagic Stroke Group,
there were twelve men (63.2%) and seven females
(36.6%). Among the subjects, 57.9% had a right-sided

the participants, 18 had diabetes and 28 had
hypertension. Patients were evenly distributed across
the two groups.

a more substantial increase to 33.58 (SD = 6.842) after
the intervention period. An independent samples t-test
indicated a statistically significant difference in the
change of MAS scores between the two stroke types
after 4 weeks (t(36) = -2.929, p = .006), with a large
effect size (Cohen's d = .95). The mean difference
between the groups was -6.474, favoring the
hemorrhagic stroke group. Furthermore, a paired

(r = .658, p = .002) demonstrated a strong positive
relationship between initial and subsequent MAS
scores, suggesting consistent improvement.

The mean FIM score at admission for ischemic stroke
patients was 55.21 (SD = 11.712), improving to 79.11
(SD = 18.275) after 4 weeks. Similarly, hemorrhagic
stroke patients' mean FIM score improved from 54.58
(SD = 11.815) at admission to 90.11 (SD = 14.059) after
4 weeks (Table 1). The change in FIM scores was also
statistically significant (t(36) = -2.08, p = .045) with a
notable effect size (Cohen's d = 16.31), with the mean
difference of -11 indicating greater functional gains for
the hemorrhagic stroke group. Correlation analyses
revealed a significant relationship between initial and
final FIM scores for hemorrhagic stroke patients (r =
.513, p = .025), denoting a positive therapeutic effect.
These results underscore the significant
improvements in the functional outcomes observed in
both ischemic and hemorrhagic stroke patients
following physical therapy, with hemorrhagic stroke
patients showing more substantial gains in both MAS
and FIM scores. The high effect sizes suggest that
these improvements are both statistically and
clinically meaningful, indicating the efficacy of the
physical therapy interventions implemented in the
study.

Discussion
The purpose of our research was to evaluate the
effects of the Motor Relearning Programme (MRP) on
the functional outcomes of individuals with acute
ischemic and hemorrhagic strokes. By doing thorough
analysis, we were able to identify important
observations on the impact of stroke type on the
progress and results of early rehabilitation. Both the
ischemic and hemorrhagic stroke groups showed
improvements in their motor skills and functional
independence, as measured by the Motor Assessment
Scale (MAS) and Functional Independence Measure
(FIM). The group of patients with hemorrhagic stroke
showed statistically significant improvements in both
MAS and FIM ratings, revealing a unique pattern of
recovery. The diverging path taken by hemorrhagic and
ischemic stroke patients may be due to a fundamental
difference in how they respond to early physical
therapy therapies. Despite not all differences achieved
statistical significance for tests, hemorrhagic stroke
patients showed quick improvement, sometimes
surpassing the ischemic group in functional recovery,
despite beginning from comparable baselines.
Previous research by Paolucci et al. (2003) has shown
that hemorrhagic stroke patients have a more
favorable improvement in mobility and neurological
outcomes compared to individuals with ischemic
strokes. The results of our study support these
observations and indicate that tailoring rehabilitation
regimens to the specific kind of stroke may play a
crucial role in maximizing recovery outcomes. Given
the rapid progress in treating hemorrhagic stroke
patients, it may be advantageous to enhance
rehabilitation programmes by adjusting the intensity
and timing of therapies to take full advantage of this
period of accelerated recovery.
The findings of Salvadori et al. (2020) align with our
results since they also identified specific difficulties in
the recovery process for patients with hemorrhagic
and ischemic strokes. Notably, the former group saw a
higher occurrence of complications. Our study
emphasizes the need for a proactive treatment plan in
these patients, which may include comprehensive
surveillance and integrated care that treats problems
with the administration of physical therapy. In line with
the principles stated by Wei et al. (2024), our study
emphasizes the need of starting rehabilitation as soon
as medically possible after a stroke. Prompt
intervention is crucial, as our findings demonstrate
that significant improvements in functionality may be
achieved from the beginning of treatment. This
discovery is very important for clinical practice,
supporting the development of recommendations that
emphasize the need of prompt rehabilitation efforts.
Furthermore, the lack of noticeable disparities in
certain functional activities across the groups may
suggest that although overall improvements are
evident, the detailed and individualized nature of
functional enhancement requires more complex and
personalized therapy approaches. This is supported by
the personalized therapy requirements described by
Kartashev et al. (2020).
The continuous improvement seen in both groups over
the four-week intervention highlights the potential
benefits of long-lasting and perhaps extended
rehabilitation programmes. This is consistent with the
perspective of Nas et al. (2015), who suggest that long-
term rehabilitation may help support continuous
healing. The findings of our research suggest that
providing rehabilitative treatment beyond the acute
period might enhance functional independence and
quality of life, especially in stroke patients with
significant initial impairments.
The current research highlights the ability of
hemorrhagic stroke patients to positively respond to
early and intensive rehabilitation. This challenges us to
improve our methods to take full advantage of this
responsiveness. Although therapies are beneficial for
ischemic stroke patients, the research suggests that
customized tactics are necessary to optimize the
therapeutic effectiveness for each kind of stroke,
thereby enhancing overall patient outcomes.
Conclusion
Our study contributes to a nuanced understanding of
stroke rehabilitation, emphasizing that while both
ischemic and hemorrhagic stroke patients
significantly benefit from structured physical therapy
interventions like MRP, the specifics of their recovery
processes vary. This variation underscores the
necessity for personalized rehabilitation strategies
that consider the unique physiological and recovery
needs of each stroke subtype. Moving forward, it is
crucial for future research to not only refine these
strategies but also to explore the integration of novel
therapeutic modalities that could complement
traditional physical therapy to optimize recovery
outcomes for all stroke patients.

Introduction At present, stroke has become the first cause of death and disability among Chinese adults. With the coming of the aging population in China, the disease burden brought by stroke will be increasingly aggravated. And stroke is a leading cause of disability. There is a golden plastic period after stroke, during which timely and safe intervention and rehabilitation therapy can effectively improve the disability status. However, there is still controversy about the duration of interventional rehabilitation after stroke. This study conducted a meta-analysis on the influence of intervention in early and late ischemic stroke rehabilitation. Method Chinese language databases such as CNKI, Wanfang, and VIP, and English language databases such as Embase, PubMed, Web of Science, and The Cochrane Library were searched, and RCT related to early and late rehabilitation of ischemic stroke from the establishment of the database to October 2023 was collected. Review Manager 5.4.1 was used for relevant analysis. The main outcomes were Barthel Index or Modified Barthel Index, Fugl-Meyer Assessment scale, NIHSS, China Stroke Scale. Standardized Mean Difference (SMD) was used as an effective indicator of continuity variables, and the estimated interval was expressed by 95% confidence interval (CI). Results A total of 1908 patients were included in 16 studies. The results showed that, compared with late rehabilitation, early rehabilitation improved clinical efficacy. Barthel Index or Modified Barthel Index score was [SMD = 1.40, 95%CI(1.16,1.63), p < 0.001]; the score of Fugl-Meyer Assessment Scale was [SMD = 1.18, 95%Cl (0.85, 1.52), P < 0.001]; the score of NIHSS was [SMD= -0.44, 95% CI(-0.65, -0.24), P < 0.001]; the result of China Stroke Scale score was [SMD= -0.37, 95%CI(-0.56, -0.18), P < 0.001]. Conclusion In comparison with late rehabilitation, early rehabilitation can significantly improve self-care abilities, daily activities, and neurological functions of ischemic stroke patients. Trial registration This meta-analysis has been registered with Prospero, and the registration number is CRD42022309911. The registration period is March 22, 2022.

The high prevalence of ischemic stroke and high mortality from it with increasing disability of such patients currently makes the problem of vascular diseases of the brain one of the most socially significant and requiring additional research. Conducting physical rehabilitation in post-stroke patients according to the author's scheme had a pronounced positive effect on their hematological parameters, regardless of their initial state. Wellness measures ensured in all patients who had an ischemic stroke a gradual optimization of the number of red blood cells, white blood cells and platelets in the blood. The upcoming changes created conditions for improving trophic tissue of patients, increased their overall reactivity and minimized the risk of repeated ischemic damage to brain tissue. The results suggest that the author's option of rehabilitation of post-stroke patients is highly promising in terms of ensuring adequate activation of the bone marrow regardless of the initial level of erythropoiesis, leukopoiesis and thrombocytopoiesis. This prevents anemia, weakening of resistance and thrombophilia in such patients, optimizing the general condition and significantly improving the prognosis for the disease and for life.

Comparison studies on recovery outcomes in ischemic (IS) and hemorrhagic strokes (HS) have yielded mixed results. In this retrospective observational study of consecutive IS and HS patients, we aimed at evaluating functional outcomes at discharge from an intensive rehabilitation hospital, comparing IS vs. HS, analyzing possible predictors. Modified Rankin Scale (mRS) at discharge was the main outcome. Out of the 229 patients included (mean age 72.9 ± 13.9 years, 48% males), 81 had HS (35%). Compared with IS (n = 148), HS patients were significantly younger (75 ± 12.5 vs. 68.8 ± 15.4 years, p = 0.002), required longer hospitalizations both in acute (23.9 ± 36.7 vs. 35.2 ± 29.9 days, p = 0.019) and rehabilitation hospitals (41.5 ± 31.8 vs. 77.2 ± 51.6 days, p = 0.001), and had more severe initial clinical deficit (mean number of neurological impairments: 2.0 ± 1.1 vs. 2.6 ± 1.4, p = 0.001) and mRS scores at admission (p = 0.046). At discharge, functional status change, expressed as mRS, was not significantly different between IS and HS (F = 0.01, p = 0.902), nor was the discharge destination (p = 0.428). Age and clinical severity were predictors of functional outcome in both stroke types. On admission in an intensive rehabilitation hospital, HS patients presented a worse functional and clinical status compared to IS. Despite this initial gap, the two stroke types showed an overlapped trajectory of functional recovery, with age and initial stroke severity as the main prognostic factors.

Stroke is the second leading cause of death and a major contributor to disability worldwide. The prevalence of stroke is highest in developing countries, with ischemic stroke being the most common type. Considerable progress has been made in our understanding of the pathophysiology of stroke and the underlying mechanisms leading to ischemic insult. Stroke therapy primarily focuses on restoring blood flow to the brain and treating stroke-induced neurological damage. Lack of success in recent clinical trials has led to significant refinement of animal models, focus-driven study design and use of new technologies in stroke research. Simultaneously, despite progress in stroke management, post-stroke care exerts a substantial impact on families, the healthcare system and the economy. Improvements in pre-clinical and clinical care are likely to underpin successful stroke treatment, recovery, rehabilitation and prevention. In this review, we focus on the pathophysiology of stroke, major advances in the identification of therapeutic targets and recent trends in stroke research.

Objectives: This study aims to evaluate the effects of blood pressure (BP) on functional recovery and length of stay (LOS) in post-stroke patients in an acute rehabilitation facility (ARF). Patients and methods: A total of 116 ischemic stroke patients (60 males, 56 females; mean age 70.0±12.8 years; range, 37 to 93 years) who were admitted to the ARF between January 2012 and September 2012 were included. Daily BP measurements with mean systolic and diastolic BP values and Functional Independent Measure (FIM) scores at the time of admission and discharge were measured. The LOS and systolic and diastolic BP ranges were also recorded. Results: There was no significant correlation between the BP and FIM scores. The mean diastolic BP was positively correlated with admission (rs=0.316, p=0.01) and discharge (rs=0.287, p=0.002), FIM scores, and FIM effectiveness (rs=0.185, p=0.047) and negatively correlated with age (r=-0.449, p<0.001) and LOS (rs=-0.189, p=0.042). The LOS in hospital was negatively correlated with FIM scores at admission (rs=-0.585, p<0.001) and discharge (rs=-0.352, p<0.001) and positively correlated with FIM score changes (rs=0.414, p<0.001). Conclusion: Our study results show that diastolic BP in the subacute phase of stroke does not have a major impact on the functional recovery and LOS in post-stroke patients. However, there is a significant correlation between diastolic BP values and FIM efficiency.

The purpose of this study was to investigate the outcome of rehabilitation following cerebrovascular accident (CVA) in one Sydney unit. This unit has implemented a philosophy of training based on a motor learning model for rehabilitation proposed by Carr and Shepherd (1987a and b). The proposed motor learning model stresses the need for task and context specific training of everyday actions. Data, including patient characteristics and Motor Assessment Scale (MAS) scores, were collected through a retrospective audit of all patients diagnosed as having a CVA and discharged from the unit during 1989. The major finding of this study was that, following rehabilitation within a multi-disciplinary program, patients were able to improve their motor performance as demonstrated by changes in MAS scores. The measurement of outcome of rehabilitation for this unit has contributed to quality assurance by identifying motor tasks that warrant further emphasis in training in order to improve upon the reported outcome of rehabilitation.

This study was conducted to establish the concurrent validity and interrater reliability of the Motor Assessment Scale (MAS) for stroke patients. Thirty hemiplegic subjects were tested with the MAS and the Fugl-Meyer Assessment (FMA), a reliable and validated test of motor function in stroke patients. The high correlations obtained between the total scores on the MAS and the FMA (r = .88) and between specific item scores (except sitting balance) (r = .28 to .92) provide support for the concurrent validity of the MAS. Interrater reliability coefficients for the total MAS score and individual items on the MAS (except tone) were also high and significant.

The purpose of this paper is to present and describe a motor assessment scale (MAS) for stroke patients and to report on the investigation of two aspects of its reliability. The MAS is a brief and easily administered assessment of eight areas of motor function and one item related to muscle tone. Each item is scored on a scale from 0 to 6. To check interrater reliability, we videotaped five stroke patients while they were being assessed with the MAS. These scores were used as the criterion ratings. Twenty raters then assessed these patients, and their results were correlated with the criterion ratings. We determined test-retest reliability by assessing on two occasions, separated by a four-week interval, 14 stroke patients whose recovery was considered to be stable and by correlating these scores. The MAS was found to be highly reliable with an average interrater correlation of .95 and an average test-retest correlation of .98.

Analysis of early deaths after stroke is important, since some deaths may be preventable. Previous studies have relied on retrospective and often incomplete clinical data, for comparison with pathological findings. The present study is based on 1073 consecutive stroke patients admitted to an intensive care stroke unit from a well-defined population. There were 212 deaths within the first 30 days, yielding a mortality rate of 20%. Clinical, radiological, and laboratory data were collected prospectively according to a standardized protocol. Autopsies were performed on 90 of the 212 patients, and CT scanning on a further 27. Early mortality after stroke exhibits a bimodal distribution. One peak occurs during the first week, and a second during the second and third weeks. The majority of deaths in the first week are due to transtentorial herniation. Of these, deaths due to hemorrhage usually occur within the first three days, whilst deaths due to infarction peak between the third and sixth day post ictus. After the first week, deaths due to relative immobility (pneumonia, pulmonary embolism and sepsis) predominate, peaking towards the end of the second week. Cardiac deaths occur throughout the first month, and unfortunately account for many deaths in patients with small functional deficits.
