The Effect of Local Injections in Hemiplegic Shoulder Pain: A Prospective, Randomized, Controlled Study

Assessment approaches for hemiplegic shoulder pain in people living with stroke - A scoping review

PURPOSE

Hemiplegic shoulder pain (HSP) is reported in up to 40% of people with stroke. Causes of HSP are often multifactorial. To inform appropriate treatment, reliable/valid assessments are critical. The aim of this scoping review was to collate assessment approaches used in studies where the primary outcome was HSP, and to identify how frequently each assessment approach was used.

METHODS

A systematic search, including studies from 2000-2023 was conducted of the MEDLINE, EMBASE, CINAHL, AMED, Biomed Central, and Cochrane Library databases, with four key terms used: "assess", "stroke", "pain" and "shoulder". All primary studies published in English language fulfilling the reviews inclusion criteria were included. Six reviewers extracted the data.

RESULTS

A total of 29 assessment methods for HSP were identified from 124 studies. The common assessments were: Visual Analogue Scale (n = 75, 60%), Passive Range of Movement (n = 65, 52%), Fugl-Meyer Assessment (n = 32, 26%), glenohumeral subluxation (n = 30, 24%) and Numerical Rating Scale (n = 27, 22%).

CONCLUSION

A wide range of assessment approaches was identified for HSP, and some are used more than others. A fully comprehensive assessment that considers different aspects of pain including severity and timing, functioning, and the psychological burden, is needed in this area of practice to be able to guide appropriate treatment.

Ultrasound-guided glenohumeral joint injections for shoulder pain in ALS: A case series

Introduction

Shoulder pain is a common secondary impairment for people living with ALS (PALS). Decreased range of motion (ROM) from weakness can lead to shoulder pathology, which can result in debilitating pain. Shoulder pain may limit PALS from participating in activities of daily living and may have a negative impact on their quality of life. This case series explores the efficacy of glenohumeral joint injections for the management of shoulder pain due to adhesive capsulitis in PALS.

Methods

People living with ALS and shoulder pain were referred to sports medicine-certified physiatrists for diagnostic evaluation and management. They completed the Revised ALS Functional Rating Scale and a questionnaire asking about their pain levels and how it impacts sleep, function, and quality of life at baseline pre-injection, 1-week post-injection, 1 month post-injection, and 3 months post-injection.

Results

We present five cases of PALS who were diagnosed with adhesive capsulitis and underwent glenohumeral joint injections. Though only one PALS reported complete symptom resolution, all had at least partial symptomatic improvement during the observation period. No complications were observed.

Conclusions

People living with ALS require a comprehensive plan to manage shoulder pain. Glenohumeral joint injections are safe and effective for adhesive capsulitis in PALS, but alone may not completely resolve shoulder pain. Additional therapies to improve ROM and reduce pain should be considered.

Effectiveness of acupuncture combined with rehabilitation training vs. rehabilitation training alone for post-stroke shoulder pain: A systematic review and meta-analysis of randomized controlled trials

Background

Post-stroke shoulder pain (PSSP) is characterized by shoulder pain on the hemiplegic side, which can limit physical activity in patients with stroke. Acupuncture combined with rehabilitation training (AR) has been widely used in PSSP, but the evidence of its effectiveness is still unclear.

Objective

The study aimed to evaluate the effect and safety of AR vs. rehabilitation training (RT) alone on PSSP.

Methods

We searched PubMed, the Cochrane Library, the Chinese Biological Medicine Database (CBM), the Chinese Scientific Journal Database (VIP), China National Knowledge Infrastructure (CNKI), and the WAN FANG database for relevant studies from their inception to February 2022. Only randomized controlled trials (RCTs) comparing the effect of AR with RT alone on PSSP were considered. The primary outcome was shoulder pain. Secondary outcomes included upper limb motor function, activities of daily living (ADL), shoulder range of motion (ROM), and adverse events (AEs). Subgroup analysis and sensitivity analysis were also conducted. Quality assessment was implemented based on Cochrane risk of bias (ROB) criteria, which consist of seven items. When more than four items in a study were judged as low ROB, the overall quality of this study was considered low risk.

Results

A total of 40 studies were included in the qualitative analysis, and 35 (87.5%) studies with 2,554 patients were included in the meta-analysis. Of the 40 studies, 14 (35.0%) were of moderate-to-high quality. The meta-analysis results showed that AR is better than RT alone in reducing shoulder pain (MD -1.32, 95% CI -1.58 to -1.07), improving upper limb motor function (MD 6.81, 95% CI 4.95-8.67), ADL (MD 11.17, 95% CI 9.44-12.91), and shoulder ROM (internal rotation: MD 10.48, 95% CI 8.14-12.83; backward extension: MD 7.82, 95% CI 6.00-9.64; anteflexion: MD 12.88, 95% CI 5.47-20.29; external rotation: MD 11.40, 95% CI 6.17-16.64; abduction: MD 16.96, 95% CI 8.61-25.31) without obvious AEs.

Conclusion

AR may be better than RT alone for the improvement of shoulder pain, upper limb motor function, ADL, and shoulder ROM, without obvious AEs in patients with PSSP. However, considering the clinical and statistical heterogeneity, our findings need to be interpreted with caution. More rigorous RCTs in this area should be conducted in the future.

The Effectiveness of Ultrasound-Guided Subacromial-Subdeltoid Bursa Combined With Long Head of the Biceps Tendon Sheath Corticosteroid Injection for Hemiplegic Shoulder Pain: A Randomized Controlled Trial

Background

Subacromial-subdeltoid (SASD) bursa and long head of the biceps tendon (LHBT) sheath corticosteroid injection are commonly used to treat shoulder pain associated with arthritic shoulder conditions, but effectiveness in the stroke population is unclear. This study aimed to investigate the clinical effectiveness of ultrasound-guided SASD bursa combined with LHBT sheath corticosteroid injection for hemiplegic shoulder pain (HSP) compared with SASD bursa injection alone.

Methods

60 patients with HSP were randomly allocated to the dual-target group (n = 30) and single-target group (n = 30). The single-target group received SASD bursa corticosteroid injection alone, and the dual-target group received SASD bursa and LHBT sheath corticosteroid injection. The primary endpoint was pain intensity measured on a visual analog scale (VAS). The secondary endpoint was passive range of motion (PROM) of the shoulder, Upper Extremity Fugl-Meyer assessment (UEFMA) score, and Modified Barthel Index (MBI) score. PROM and pain intensity VAS were assessed at baseline and weeks 1, 4, and 12 post-treatment. UEFMA and MBI were recorded at baseline and weeks 4 and 12 post-treatment.

Results

A total of 141 patients with HSP were screened, and 60 patients were included. Significant differences in the VAS, PROM, UEFMA and MBI were observed at all follow-ups in both groups. The dual-target group showed a significant difference in VAS score compared with the single-target group (3.3 vs. 3.7, p = 0.01) at week 4 and week 12 (2.5 vs. 3.2, p < 0.001). Moreover, the dual-target group showed statistically significant differences in flexion (p < 0.001) at week 12, extension rotation (p < 0.001) at week 12, and abduction at week 1 (p = 0.003) and weeks 4 and 12 (p < 0.001) compared with the single-target group. There were significant differences in FMA and MBI scores in the two groups before and after treatment (p < 0.001), with a more significant increase in the dual-target group compared with the single-target group (p < 0.001) at week 12.

Conclusion

The combination of SASD bursa and LHBT sheath corticosteroid injection is superior to SASD bursa injection alone in reducing shoulder pain and improving functional activities in patients with HSP.

Brazilian Academy of Neurology practice guidelines for stroke rehabilitation: part I

The Guidelines for Stroke Rehabilitation are the result of a joint effort by the Scientific Department of Neurological Rehabilitation of the Brazilian Academy of Neurology aiming to guide professionals involved in the rehabilitation process to reduce functional disability and increase individual autonomy. Members of the group participated in web discussion forums with predefined themes, followed by videoconference meetings in which issues were discussed, leading to a consensus. These guidelines, divided into two parts, focus on the implications of recent clinical trials, systematic reviews, and meta-analyses in stroke rehabilitation literature. The main objective was to guide physicians, physiotherapists, speech therapists, occupational therapists, nurses, nutritionists, and other professionals involved in post-stroke care. Recommendations and levels of evidence were adapted according to the currently available literature. Part I discusses topics on rehabilitation in the acute phase, as well as prevention and management of frequent conditions and comorbidities after stroke.

Comparative Effectiveness of Injection Therapies for Hemiplegic Shoulder Pain in Stroke: A Systematic Review and Network Meta-Analysis

Hemiplegic shoulder pain (HSP) hampers post-stroke functional recovery and is not well managed with conservative treatments. This systematic review aimed to examine the various injection therapies for HSP and investigate their effectiveness at different time points. The protocol of this meta-analysis was registered on INPLASY with a registration number of INPLASY202180010. PubMed, EMBASE, and Scopus were searched from their inception to 4 August 2021 for the clinical studies investigating comparative effectiveness of different injection regimens for treating hemiplegic shoulder pain in patients with stroke. The primary outcome was the weighted mean difference (WMD) on the visual analog scale (VAS) of pain reduction in the fourth-week and between the fourth and twenty-fourth weeks. Ranking probabilities of the WMD for each treatment were obtained using simulations. Seventeen studies with 595 participants were included. The network meta-analysis showed that at the fourth-week, intra-muscular botulinum toxin (BoNT) injections and suprascapular nerve blocks (SSNB) were superior to a placebo, with WMDs of 1.55 (95% CI, 0.09 to 3.01) and 1.44 (95% CI, 0.07 to 2.80), respectively. SSNB possessed the highest probability (53.3%) and appeared to be the best treatment in the fourth-week, followed by intra-muscular BoNT injections (42.6%). Intramuscular BoNT injections were better than the placebo, with a WMD of 1.57 (95% CI, 0.30 to 2.84) between the 4th and 24th weeks. Intramuscular BoNT injections had the highest probability (79.8%) as the best treatment between the 4th and 24th weeks. SSNB was likely to rank first in relieving HSP at the fourth post-treatment week, whereas intra-muscular BoNT injections had the highest probability to achieve the best treatment effectiveness in the post-injection period between the fourth and twenty-fourth weeks. However, as some of the included studies used a non-randomized controlled design, more randomized controlled trials are needed in the future to validate and better understand the short- and long-term efficacy of different injection therapies for management of HSP.

Therapeutic effect of Fu's subcutaneous needling for hemiplegic shoulder pain among stroke survivors: Study protocol for a randomized controlled trial

BACKGROUND

Hemiplegic shoulder pain (HSP) is a frequent complication after stroke and limits patients' physical functioning of the affected arm, thus compromising their quality of life. Fu's subcutaneous needling (FSN) has been widely applied in the treatment of pain diseases in China; however, its efficacy and safety for HSP remain to be elucidated. We therefore conducted a randomized, controlled trial to summarize the current evidence on the effects of FSN on the recovery outcomes of stroke survivors with HSP.

METHODS

Here, we conduct a study design and protocol of a randomized, blinded, controlled study to evaluate the efficacy and safety of FSN in patients with HSP. A total of 60 patients with numerical rating scale (NRS) score above 1 will be recruited in the trial and randomized into FSN group or usual care (UC) group. Patients in the FSN group will receive FSN treatment combined with UC treatment while patients in the UC group will receive UC treatment alone for 4 weeks. The primary outcomes are changes of NRS at baseline, after the 1st treatment, after the final treatment and 4 weeks after the final treatment. Secondary measurements will be changes of Fugl-Meyer score, constant score, MPQ-SF score, quality of life score, and range of motion at baseline, after the final treatment, and 4 weeks after the final treatment. The safety will also be assessed by monitoring the incidence of adverse events and changes in vital signs during the study.

DISCUSSION

Results from this trial will significantly support the application of FSN in the recovery of patients with HSP. If found to be effective and safe, FSN will be a valuable complementary option for patients with HSP.

Effects of fluoroscopy-guıded intraartıcular injectıon, suprascapular nerve block, and combınatıon therapy ın hemıplegıc shoulder paın: a prospective double-blınd, randomızed clınıcal study

OBJECTIVE

To investigate the effect and superiority of fluoroscopy-guided intraarticular shoulder injection (IAI), suprascapular nerve block (SSNB), and combination treatment in hemiplegic shoulder pain (HSP).

DESIGN

We included 30 patients diagnosed with HSP. Patients were divided into three groups: IAI, SSNB, and combination treatment. Patients were assessed using a visual analogue scale (VAS) prior to the injection and at hour 1, week 2, and month 2 after the injection, with goniometry at two angles at the moment that pain started and maximum passive range of motion (ROM) of the shoulder and Modified Barthel Index prior to the injection, at week 2 and month 2 after the injection.

RESULTS

Significant decrease in the VAS and increase in shoulder passive ROMs were detected at all follow-ups in groups. In comparison, there was no significant difference in VAS scores. Change in the internal rotation at the moment that pain started was found to be higher in the patients treated with the combined method than the other methods. Change in maximum passive ROMs was similar between treatment groups.

CONCLUSION

IAI, SSNB, and the combination treatments are reliable and effective treatment modalities that provide pain relief and an increase in shoulder passive ROMs in HSP.

The long-term effects of hyaluronic acid on hemiplegic shoulder pain and injury in stroke patients: A randomized controlled study

BACKGROUND

Hemiplegic shoulder pain (HSP) is one common complication after stroke. The interferes with the functionality of the affected shoulder in patients with stroke during rehabilitation. Hyaluronic acid (HA) could have positive effects on pain relief and shoulder motion in stroke patients with hemiplegic shoulders. We investigated long-term benefits of HA injection in stroke patients with HSP and rotator cuff injury.

METHODS

A randomized, double-blinded controlled trial was conducted in one medical center. The stroke patients with HSP and rotator cuff injury were randomized and allocated to the control (n = 9) and experimental (n = 18) groups. The control and the experimental groups received ultrasound-guided subacromial 0.9% sodium chloride and HA injections, respectively. All injections were performed once per week for 3 weeks. The associated upper extremity functional assessments, shoulder pain scale, and sonography findings on affected shoulders were measured before interventions and at the 4th and 12th week after local injections.

RESULTS

The visual analog scale (VAS) scores of HSP were significantly reduced in the control and experimental groups at the 4th week following intervention. Additionally, the VAS score at the 12th week was also significantly reduced in the experimental group. Significant differences were found in the hyperemia occurrence in the subscapularis tendon at the 12th week after intervention (P = .018) and in the severity of hyperemia in the long head of the biceps tendon (P = .042) and the subscapularis tendon after intervention (P = .014).

CONCLUSION

Subacromial HA injections might provide longer HSP reduction and decrease in hyperemia reactions at the long head of biceps tendon and subscapularis tendon in stroke patients with HSP and tendon injury.

Effect of EMG-triggered neuromuscular electrical stimulation with bilateral arm training on hemiplegic shoulder pain and arm function after stroke: a randomized controlled trial

BACKGROUND

Hemiplegic shoulder pain is a frequent complication after stroke, leading to limited use of the affected arm. Neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation (TENS) are two widely used interventions to reduce pain, but the comparative efficacy of these two modalities remains uncertain. The purpose of this research was to compare the immediate and retained effects of EMG-triggered NMES and TENS, both in combination with bilateral arm training, on hemiplegic shoulder pain and arm function of stroke patients.

METHODS

A single-blind, randomized controlled trial was conducted at two medical centers. Thirty-eight patients (25 males and 13 females, 60.75 ± 10.84 years old, post stroke duration 32.68 ± 53.07 months) who had experienced a stroke more than 3 months ago at the time of recruitment and hemiplegic shoulder pain were randomized to EMG-triggered NMES or TENS. Both groups received electrical stimulation followed by bilateral arm training 3 times a week for 4 weeks. The primary outcome measures included a vertical Numerical Rating Scale supplemented with a Faces Rating Scale, and the short form of the Brief Pain Inventory. The secondary outcome measures were the upper-limb subscale of the Fugl-Meyer Assessment, and pain-free passive shoulder range of motion. All outcomes were measured pretreatment, post-treatment, and at 1-month after post-treatment. Two-way mixed repeated measures ANOVAs were used to examine treatment effects.

RESULTS

Compared to TENS with bilateral arm training, the EMG-triggered NMES with bilateral arm training was associated with lower pain intensity during active and passive shoulder movement (P =0.007, P =0.008), lower worst pain intensity (P = 0.003), and greater pain-free passive shoulder abduction (P =0.001) and internal rotation (P =0.004) at follow-up. Both groups improved in pain at rest (P =0.02), pain interference with daily activities, the Fugl-Meyer Assessment, and pain-free passive shoulder flexion and external rotation post-treatment (P < 0.001) and maintained the improvement at follow-up (P < 0.001), except for resting pain (P =0.08).

CONCLUSIONS

EMG-triggered NMES with bilateral arm training exhibited greater immediate and retained effects than TENS with bilateral arm training with respect to pain and shoulder impairment for chronic and subacute stroke patients with hemiplegic shoulder pain.

The effects of hyaluronic acid on hemiplegic shoulder injury and pain in patients with subacute stroke: A randomized controlled pilot study

BACKGROUND

Hemiplegic shoulder pain (HSP) is one of the most common comorbidities in stroke patients with flaccid shoulders. The pain limits functional motor recovery and affects the activities of daily living after acute stroke. This study investigated the effects of hyaluronic acid (HA) injection on pain reduction and motor function in subacute stroke patients with HSP and injury.

METHODS

A randomized, double-blinded controlled trial was conducted in a medical center. Twenty-six subacute stroke patients were enrolled and randomly divided into 2 groups: the experimental group (n = 16) received ultrasound-guided, subacromial HA injections once per week for 3 weeks and conventional rehabilitation, whereas the control group (n = 10) received 0.9% sodium chloride injections once per week for 3 weeks and conventional rehabilitation. Shoulder pain and motor function were evaluated before and after the intervention using the visual analog scale (VAS) and the Fugl-Meyer assessment for the upper extremity (FMA-UE), respectively.

RESULTS

In the experimental group, significant differences were found in VAS (P = 0.003), shoulder flexion (P = 0.03) and abduction (P = 0.02), and FMA-UE (P = 0.003) after treatment. In the control group, there were significant differences in VAS (P = 0.007), shoulder flexion (P = 0.035), and FMA-UE (P = 0.042) after treatment. The comparison of the changes in the parameters between the experimental and control groups, after each intervention, revealed a significant difference in VAS (P = 0.001).

CONCLUSION

Subacromial HA injection could result in positive effects on shoulder pain and shoulder abduction in subacute stroke patients with HSP and injury.

Guidelines for Adult Stroke Rehabilitation and Recovery: A Guideline for Healthcare Professionals From the American Heart Association/American Stroke Association

PURPOSE

The aim of this guideline is to provide a synopsis of best clinical practices in the rehabilitative care of adults recovering from stroke.

METHODS

Writing group members were nominated by the committee chair on the basis of their previous work in relevant topic areas and were approved by the American Heart Association (AHA) Stroke Council's Scientific Statement Oversight Committee and the AHA's Manuscript Oversight Committee. The panel reviewed relevant articles on adults using computerized searches of the medical literature through 2014. The evidence is organized within the context of the AHA framework and is classified according to the joint AHA/American College of Cardiology and supplementary AHA methods of classifying the level of certainty and the class and level of evidence. The document underwent extensive AHA internal and external peer review, Stroke Council Leadership review, and Scientific Statements Oversight Committee review before consideration and approval by the AHA Science Advisory and Coordinating Committee.

RESULTS

Stroke rehabilitation requires a sustained and coordinated effort from a large team, including the patient and his or her goals, family and friends, other caregivers (eg, personal care attendants), physicians, nurses, physical and occupational therapists, speech-language pathologists, recreation therapists, psychologists, nutritionists, social workers, and others. Communication and coordination among these team members are paramount in maximizing the effectiveness and efficiency of rehabilitation and underlie this entire guideline. Without communication and coordination, isolated efforts to rehabilitate the stroke survivor are unlikely to achieve their full potential.

CONCLUSIONS

As systems of care evolve in response to healthcare reform efforts, postacute care and rehabilitation are often considered a costly area of care to be trimmed but without recognition of their clinical impact and ability to reduce the risk of downstream medical morbidity resulting from immobility, depression, loss of autonomy, and reduced functional independence. The provision of comprehensive rehabilitation programs with adequate resources, dose, and duration is an essential aspect of stroke care and should be a priority in these redesign efforts.

The application of sonography in shoulder pain evaluation and injection treatment after stroke: a systematic review

[Purpose] This review article is designed to expose the application of sonography in shoulder pain after stroke. [Methods] A range of databases was searched to identify articles that address sonography examination, with or without ultrasound guided corticosteroid injection for hemiplegic shoulder pain (HSP). The electronic databases of PubMed, CENTRAL, CINAHL, Cochrane Library, Medline were searched. [Results] According to the articles identified in our databases research, sonographic technique has potential to provide objective measurements in patients with HSP. The main sonography finding of HSP included subacromial subdeltoid (SASD) bursal effusion, tendinosis of the supraspinatus and subscapularis tendon, long head of biceps tendon sheath effusion, and shoulder subluxation. Our analysis also revealed significantly decreased pain score (VAS) and increased passive external rotation degree in the steroid injection group than control group. [Conclusion] The sonography examination is useful for HSP assessment and ultrasound guided technique is recommended for HSP injection treatment.

Evidence for therapeutic interventions for hemiplegic shoulder pain during the chronic stage of stroke: a review

OBJECTIVE

To determine the effectiveness of therapeutic interventions targeting hemiplegic shoulder pain (HSP) more than 6 months post stroke.

METHODS

A literature search of multiple databases (PubMed, CINAHL, Ovid, and EMBASE) was conducted to identify articles published in the English language from 1980 to April 2012. Studies were included if (1) all participants were adults who had sustained a stroke; (2) research design was a randomized controlled trial (RCT) that examined the effectiveness of any treatment for HSP; (3) all participants had experienced stroke at least 6 months previously; and (4) an assessment of pain had been conducted before and after treatment using a standardized method. The following data were extracted: patient characteristics (ie, age, gender, time since stroke), sample size, study design, measurement of pain pre and post treatment, and adverse events.

RESULTS

Ten RCTs (PEDro scores 4-9) met inclusion criteria and included a total sample size of 388 individuals with a mean age of 53.2 years (range, 43.6-73.2). Mean time post stroke was 18.4 months. Three studies addressed the use of botulinum toxin type A (BTx-A); 2 studies examined electrical stimulation; 3 studies focused on intraarticular glenohumeral corticosteroid injections; 1 studied subacromial corticosteroid injections; and 1 study looked at massage therapy.

CONCLUSIONS

Positive outcomes were noted with the use of corticosteroid injections and electrical stimulation and conflicting results were seen regarding the use of BTx-A. Overall, these targeted therapies provide benefit in the treatment of HSP in individuals who are more than 6 months post stroke.

[Early rehabilitation for neurologic patients]

Rehabilitation improves the functional prognosis of patients after a neurologic lesion, and tendency is to begin rehabilitation as soon as possible. This review focuses on the interest and the feasibility of very early rehabilitation, initiated from critical care units. It is necessary to precisely assess patients' impairments and disabilities in order to define rehabilitation objectives. Valid and simple tools must support this evaluation. Rehabilitation will be directed to preventing decubitus complications and active rehabilitation. The sooner rehabilitation is started; the better functional prognosis seems to be.

Review of the randomized clinical stroke rehabilitation trials in 2009

Background

Recent review of the available evidence on interventions for motor recovery after stroke, showed that improvements in recovery of arm function were seen for constraint-induced movement therapy, electromyographic biofeedback, mental practice with motor imagery, and robotics. Similar improvement in transfer ability or balance were seen with repetitive task training, biofeedback, and training with a moving platform. Walking speed was improved by physical fitness training, high-intensity physiotherapy and repetitive task training. However, most of these trials were small and had design limitations.

Material/Methods

In this article, randomized control trials (RCT’s) published in 2009 of rehabilitation therapies for acute (≤2 weeks), sub-acute (2 to 12 weeks) and chronic (≥12 weeks) stroke was reviewed. A Medline search was performed to identify all RCT’s in stroke rehabilitation in the year 2009. The search strategy that was used for PubMed is presented in the Appendix 1. The objective was to examine the effectiveness of these treatment modalities in stroke rehabilitation.

Results

This generated 35 RCT’s under 5 categories which were found and analyzed. The methodological quality was assessed by using the PEDro scale for external and internal validity.

Conclusions

These trials were primarily efficacy studies. Most of these studies enrolled small numbers of patient which precluded their clinical applicability (limited external validity). However, the constraint induced movement therapy (CIT), regularly used in chronic stroke patients did not improve affected arm-hand function when used in acute stroke patients at ≤4 weeks. Intensive CIT did not lead to motor improvement in arm-hand function. Robotic arm treatment helped decrease motor impairment and improved function in chronic stroke patients only. Therapist provided exercise programs (when self-administered by patients during their off-therapy time in a rehabilitation setting) did improve arm-hand function. Tai Chi exercises helped improve balance and weight bearing. Exercise programs for community dwelling stroke patient helped maintain and even improve their functional state.
