Stroke rehabilitation outcome: the Turkish experience

An investigation of the factors that influence functional improvement in stroke rehabilitation

Background/aim

The purpose of this study was to determine effect of age, sex, affected extremity, disability severity, treatment type, cerebrovascular accident (CVA) etiology, number of treatment sessions, and CVA duration on the functional improvement of the stroke patients who participated in a physical medicine and rehabilitation program.

Materials and methods

The research sample consisted of 322 stroke patients. Clinical and demographic features including age, sex, affected extremity, disability severity, treatment type, CVA etiology, number of treatment sessions, and CVA duration were recorded. Functional status was evaluated retrospectively by using the functional independence measure (FIM) at admission and discharge.

Results

It was detected that discharge FIM score of the patients exhibited an increase of significance level (p < 0.05). It was found that age, number of treatment sessions, CVA duration and FIM admission score were determinative parameters in FIM gain level (p < 0.05) while sex, affected extremity, and CVA etiology were not effective in FIM gain level (p > 0.05).

Conclusion

Results show that functional improvement after rehabilitation was better in the younger ages, shorter CVA durations and moderate functional disturbances. The findings obtained may be useful for stroke rehabilitation triage.

Investigating Muscle Function After Stroke Rehabilitation with 31P-MRS: A Preliminary Study

BACKGROUND New evidence reveals significant metabolic changes in skeletal muscle after stroke. However, it is unknown if 31P magnetic resonance spectroscopy (31P-MRS) can evaluate these metabolic changes. Our objective here was to investigate: (a) if muscle energy metabolism changes in the affected side; (b) if muscle energy metabolism changes after rehabilitation; and (c) if energy metabolism measured by 31P-MRS can reflect changes in the Modified Modified Ashworth Scale (MMAS) and Fugl-Meyer assessment-lower extremity (FMA-LE) scores after rehabilitation. MATERIAL AND METHODS We enrolled 13 patients with stroke symptoms and hemiplegia. Lower-limb motor status on the affected side was evaluated by FMA-LE and MMAS. The 31P-MRS measures included phosphocreatine (PCr), inorganic phosphate (Pi), PCr/Pi, and pH. We statistically compared these measures in the affected and unaffected lower leg muscles before rehabilitation and after rehabilitation on the affected side. Spearman correlational analyses was performed to determine correlations between change in energy metabolism and change in FMA-LE score and MMAS score after rehabilitation. RESULTS PCr and PCr/Pi were significantly lower in the affected muscle compared to the unaffected muscle; however, there were no significant differences in Pi or pH. After rehabilitation, PCr, Pi, PCr/Pi, and pH did not significantly change. However, FMA-LE and MMAS score improved significantly after rehabilitation. Changes in energy metabolism measured by 31P-MRS had no correlation with FMA-LE change after rehabilitation. However, changes in PCr and PCr/Pi were correlated with change in MMAS score after rehabilitation. CONCLUSIONS 31P-MRS can evaluate changes in muscle energy metabolism in patients with stroke. PCr measured by 31P-MRS can reflect changes in MMAS after rehabilitation.

Comorbidity and intercurrent diseases in geriatric stroke rehabilitation: a multicentre observational study in skilled nursing facilities

Background

Older patients often have multiple comorbidities and are susceptible to develop intercurrent diseases during rehabilitation. This study investigates intercurrent diseases and associated factors in patients undergoing geriatric stroke rehabilitation, focussing on pre-existing comorbid conditions, overall comorbidity and baseline functional status.

Materials and methods

This multicentre prospective cohort study included 15 skilled nursing facilities. Data were collected at baseline and at discharge. The primary outcome measures were presence and number of intercurrent diseases. Furthermore, their impact on change in rehabilitation goals or length of stay was examined. Comorbidity was assessed with the Charlson index, and functional status with the Barthel index (BI).

Results

Of the 175 included patients, 51% developed an intercurrent disease. A lower baseline BI, a higher Charlson index, presence of diabetes mellitus (DM) and kidney disease were related to the occurrence of an intercurrent disease (p < 0.05). Moreover, a lower BI, a higher Charlson index, and particularly the presence of DM were independently associated. If both comorbidity and a lower baseline functional status were present, the odds ratio (95% CI) of developing intercurrent diseases was 6.70 [2.33-19.2], compared to 1.73 [0.52-5.72] (comorbidity only) and 1.62 [0.53-4.94] (only BI ≤ 14).

Conclusions

On admission, functional impairments and comorbidity, particularly diabetes, independently contribute to developing intercurrent diseases during geriatric stroke rehabilitation. Therefore, routine evaluation of comorbidity integrated with functional status at the start of rehabilitation is essential to identify patients at risk. Finally, particular attention should be paid to patients with DM to prevent intercurrent diseases and support optimal functional recovery .

The Impact of Comorbidity on Rehabilitation Outcome after Ischemic Stroke

SUMMARY – Comorbidity decreases survival but it still remains unknown to what extent functional recovery after ischemic stroke is affected. The aim of this research was to determine the prevalence of the most common comorbidities in patients with ischemic stroke and to examine their predictive value on the functional status and recovery. In order to obtain relevant information for this research, we conducted a prospective study over a two-year period. It included patients with acute/subacute ischemic stroke who had inhospital rehabilitation treatment in our institution. Functional status of the patients was evaluated by the following three aspects at the beginning and at the end of rehabilitation treatment: Rivermead Mobility Index was used for mobility, Barthel Index for independence in activities of daily living, and modified Rankin Scale for total disability. Modified Charlston Comorbidity Index was used to assess comorbidity. Multivariate analysis was applied to evaluate the impact of recorded comorbidities on the patient functional outcome. Independent predictors of rehabilitation success in our study were the value of modified Charlston Comorbidity Index, atrial fibrillation and myocardial infarction. Our study demonstrated that patients with more comorbidities had worse functional outcome after stroke, so it is important to consider the comorbidity status when planning the rehabilitation treatment.

A narrative review of the impact of medical comorbidities on stroke rehabilitation outcomes

PURPOSE

Medical comorbidities in stroke patients influence acute mortality, but may also affect participation of survivors in rehabilitation. There is limited research investigating the impact of comorbidities on stroke rehabilitation outcomes. The review will explore the literature on the impact of comorbidities on stroke rehabilitation outcome.

MATERIALS AND METHODS

The literature was searched systematically, including MEDLINE database, EMBASE and PsychINFO, combining variations of the terms stroke, rehabilitation and comorbidities. Results were limited to English language publications. Included studies had a functional outcome.

RESULTS

Twenty relevant articles were identified. Fifteen small prospective or large retrospective studies using global comorbidity scales produced conflicting relationships between comorbidities and rehabilitation outcomes. Five publications addressed specific comorbidities, with three studies finding negative correlation between diabetes and rehabilitation outcomes, although effects diminished with age. In general, there were discrepancies in how comorbidities were identified. Few studies specifically focused on comorbidities and/or rehabilitation outcomes.

CONCLUSIONS

There is conflicting evidence regarding the impact of comorbidities on stroke rehabilitation outcomes. However, the presence of more severe diabetes may be associated with worse outcomes. The role of comorbidities in stroke rehabilitation would be best clarified with a large cohort study, with precise comorbidity identification measured against rehabilitation specific outcomes. Implications for rehabilitation Benefit of rehabilitation after stroke in improving functional outcome is well-established. Many stroke patients have comorbid conditions which can impact rehabilitation participation, leading to less benefit obtained from rehabilitation. The burden of comorbid conditions may slow rehabilitation progress, which may warrant a longer duration of rehabilitation to obtain required functional gain to be discharged into the community.

Prevention, management, and rehabilitation of stroke in low- and middle-income countries

Although stroke incidence in high-income countries (HICs) decreased over the past four decades, it increased dramatically in low- and middle-income countries (LMICs). In this review, we describe the current status of primary prevention, treatment, and management of acute stroke and secondary prevention of and rehabilitation after stroke in LMICs. Although surveillance, screening, and accurate diagnosis are important for stroke prevention, LMICs face challenges in these areas due to lack of resources, awareness, and technical capacity. Maintaining a healthy lifestyle, such as no tobacco use, healthful diet, and physical activity are important strategies for both primary and secondary prevention of stroke. Controlling high blood pressure is also critically important in the general population and in the acute stage of hemorrhagic stroke. Additional primary prevention strategies include community-based education programs, polypill, prevention and management of atrial fibrillation, and digital health technology. For treatment of stroke during the acute stage, specific surgical procedures and medications are recommended, and inpatient stroke care units have been proven to provide high quality care. Patients with a chronic condition like stroke may require lifelong pharmaceutical treatment, lifestyle maintenance and self-management skills, and caregiver and family support, in order to achieve optimal health outcomes. Rehabilitation improves physical, speech, and cognitive functioning of disabled stroke patients. It is expected that home- or community-based services and tele-rehabilitation may hold special promise for stroke patients in LMICs.

Medical complications experienced by first-time ischemic stroke patients during inpatient, tertiary level stroke rehabilitation

[Purpose] The aim of this study was to assess the medical complications in first-time ischemic stroke patients, to identify the factors related to occurrence of complications. [Subjects and Methods] First-time ischemic stroke patients (n=81) admitted to a tertiary level inpatient rehabilitation center during a 5 year period were included in the study. The attending physiatrist noted the presence of specific medical complications and complications that required transfer to the acute care facility from patient records. The Oxfordshire Community Stroke Project classification was used to define the clinical subtypes of the ischemic stroke patients. The Charlson comorbidity index was used to evaluate co-morbid conditions. Functional disability was assessed using the Functional Independence Measure at admission and discharge. [Results] We found that 88.9% of the patients had at least one complication. The five most common complications were urinary tract infection (48.1%), shoulder pain (37.0%), insomnia (37.0%), depression (32.1%), and musculoskeletal pain other than shoulder pain (32.1%) and 11.1% of patients were transferred to acute care facility during rehabilitation period. Functional Independence Measure scores both at admission and discharge were significantly lower in patients with at least one complication than in patients with no complications. [Conclusion] Medical complications are common among patients undergoing stroke rehabilitation. Close interdisciplinary collaboration between physiatrists and other medical specialities is necessary for optimal management.

Assessment of the effects of rehabilitation after cerebrovascular accident in patients with diabetes mellitus and hypertension as risk factors

Aim:

The aim of this study is to evaluate the results of rehabilitation, to determine the prevalence of major risk factors in cerebrovascular accident and their consequences, as well as to propose measures and procedures that will affect the better rehabilitation.

Methods:

The survey analyzed: age, sex, duration of rehabilitation, activities in daily life through the Barthel index at admission and at discharge, presence of risk factors HTA and DM. The study included a total of 116 patients, the majority of patients are older than 61 years. We had 49% of male patients and 51% of female patients and they spent 31-40 days at the rehabilitation.

Results:

The most common risk factor is HTA (83%) and diabetes (33%). Most of the patients at admission had a BI from 0 to 4 (32.7%), and at discharge BI in the range 17-20 (36.2%). Statistical analysis shows that there is a statistically significant correlation between the BI at admission, BI at discharge and risk factors of HTA and diabetes mellitus.

Conclusions:

the rehabilitation results in most patients is good results of rehabilitation. The most important risk factors in patients are HTA, DM and directly affect on results of rehabilitation. For the better results we should have energetic fight against risk factors for HTA and DM through primary and secondary prevention and patient education about early detection and treatment of these risk factors.

The recovery of walking in stroke patients: a review

We reviewed the literature on walking recovery of stroke patients as it relates to the following subjects:epidemiology of walking dysfunction, recovery course of walking, and recovery mechanism of walking (neural control of normal walking, the evaluation methods for leg motor function, and motor recovery mechanism of leg).The recovery of walking is one of the primary goals in stroke patients, along with the recovery of hand function and cognition. Walking function has greater potential for recovery than hand function because motor function of the leg is less dependent on the lateral corticospinal tract than that of hand function. This suggests that detailed knowledge of walking can be used to increase the likelihood that stroke patients recover their ability to walk. Therefore, we suggest that further research should focus on these topics, especially, on the neural control mechanism of walking and motor recovery mechanisms of the leg in stroke patients.

The Impact of Previous Strokes on the Rehabilitation of Elderly Patients Sustaining a Hip Fracture

OBJECTIVE

To evaluate whether a previous stroke may affect the functional outcome gain of elderly patients undergoing rehabilitation for a hip fracture.

DESIGN

A retrospective cohort study.

SETTING

The division of geriatric medicine with rehabilitation wards at a university-affiliated referral hospital.

PARTICIPANTS

Patients with hip fractures (N=460) undergoing a standard rehabilitation course.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The functional outcome of previous stroke- and nonprevious stroke (NPS)-affected patients assessed by the FIM instrument at admission and discharge from the rehabilitation facility. Data were analyzed by t tests, Pearson correlation, chi-square tests, and linear regression analysis.

RESULTS

Both admission and discharge total FIM scores were significantly higher in NPS compared with previous stroke patients (63.53+/-19.89 vs 52.19+/-19.37, P<.001) and (84.23+/-24.93 vs 71.37+/-25.03, P=.001), respectively. However, changes in total FIM (20.70+/-11.68 vs 19.17+/-13.32, P=.38) and in motor FIM (19.84+/-10.63 vs 17.96+/-11.21, P=.23) at discharge were not statistically significant between the 2 groups. A linear regression analysis showed that a previous stroke was not predictive of a worse total FIM gain at discharge (P=.58).

CONCLUSIONS

NPS hip fracture elderly patients show higher admission and discharge FIM scores compared with previous stroke patients. Nevertheless, both groups achieve similar FIM gains during rehabilitation period. A previous stroke should not be considered as adversely affecting the rehabilitation of such patients.

Acute treatment and long-term management of stroke in developing countries

Developing countries have some of the highest stroke mortality rates in the world that account for over two-thirds of stroke deaths worldwide. Hospital-based studies suggest that the patterns of stroke types and causes of stroke differ between developing and developed countries, resulting in differing needs for acute and long-term care. Data on stroke care provision in developing countries are sparse and most of the available studies are biased towards urban settings in reasonably resourced health-care systems. A general overview shows that the quality and quantity of stroke care is largely patchy in low-income and middle-income countries, with areas of excellence intermixed with areas of severe need, depending upon patients' location, socioeconomic status, education, and cultural beliefs. Here we review the available literature on acute and long-term stroke management in developing countries. On the basis of available studies, largely from developed countries, we discuss the need to develop basic organised stroke-unit care in developing countries.
