Effects of task-oriented training on upper extremity functional performance in patients with sub-acute stroke: a randomized controlled trial

Robotic mirror therapy for stroke rehabilitation through virtual activities of daily living

Mirror therapy is a standard technique of rehabilitation for recovering motor and vision abilities of stroke patients, especially in the case of asymmetric limb function. To enhance traditional mirror therapy, robotic mirror therapy (RMT) has been proposed over the past decade, allowing for assisted bimanual coordination of paretic (affected) and contralateral (healthy) limbs. However, state-of-the-art RMT platforms predominantly target mirrored motions of trajectories, largely limited to 2-D motions. In this paper, an RMT platform is proposed, which can facilitate the patient to practice virtual activities of daily living (ADL) and thus enhance their independence. Two similar (but mirrored) 3D virtual environments are created in which the patients operate robots with both their limbs to complete ADL (such as writing and eating) with the assistance of the therapist. The recovery level of the patient is continuously assessed by monitoring their ability to track assigned trajectories. The patient's robots are programmed to assist the patient in following these trajectories based on this recovery level. In this paper, the framework to dynamically monitor recovery level and accordingly provide assistance is developed along with the nonlinear controller design to ensure position tracking, force control, and stability. Proof-of-concept studies are conducted with both 3D trajectory tracking and ADL. The results demonstrate the potential use of the proposed system to enhance the recovery of the patients.

Effects of virtual reality-based robot therapy combined with task-oriented therapy on upper limb function and cerebral cortex activation in patients with stroke

BACKGROUND

This study aimed to investigate the effects of virtual reality (VR)-based robot therapy combined with task-oriented therapy on cerebral cortex activation and upper limb function in patients with stroke.

METHODS

This study included 46 patients with hemiplegia within 1 year of stroke onset. Patients were divided into an experimental group (n = 23) and a control group (n = 23) using a computer randomization program. The experimental group received VR-based robot and task-oriented therapies, whereas the control group received only task-oriented therapy. All participants received interventions for 40 minutes per session, 5 times a week, for 8 weeks. For the pre- and post-evaluation of all participants, the Fugl-Meyer Assessment for the upper extremity, manual function test, motor activity log, and Jebsen-Taylor Hand Function Test were used to evaluate changes in upper limb function and motor-evoked potential amplitudes were measured to compare cerebral cortex activation.

RESULTS

In comparison to the control group, experimental group demonstrated an improvement in the function of the upper limb (P < .01) and activation of the cerebral cortex (P < .01).

CONCLUSION

The combined intervention of VR-based robot and task-oriented therapies is valuable for improving upper limb function and cerebral cortex activation in patients with stroke.

The improvement of fibrinogen, Ang-1, VEGF, BDNF in post-operative patients with brain trauma through target task-oriented phase training

Background

It aims to explore the effect of target task-oriented phase training on fibrinogen (Fbg), angiopoietin (Ang-1), vascular endothelial growth factor (VEGF), serum brain-derived neurotrophic factor (BDNF), and quality of life in post-operative patients with brain trauma.

Methods

142 patients with brain trauma who were operated on in neurosurgery of our hospital from March 2020 to March 2023 were chosen and separated into two groups by random number table. The control group (n=71) received routine post-operative training. The experimental group (n=71) received target task-oriented training based on the control group, and the serum cell levels of nursing for 3, 7, and 14 days were compared. Improvement of limb function and quality of life after 2, 4, and 6 weeks of nursing care is observed.

Inclusion of People With Aphasia in Stroke Trials: A Systematic Search and Review

BACKGROUND

Although people with aphasia (PwA) represent 30% of stroke survivors, they are frequently excluded from stroke research, or their inclusion is unclear. Such practice significantly limits the generalizability of stroke research, increases the need to duplicate research in aphasia-specific populations, and raises important ethical and human rights issues.

OBJECTIVE

To detail the extent and nature of inclusion of PwA in contemporary stroke randomized controlled trials (RCTs).

METHODS

We conducted a systematic search to identify completed stroke RCTs and RCT protocols published in 2019. Web of Science was searched using terms "stroke" and "randomized controlled trial". These articles were reviewed by extracting rates of PwA inclusion/exclusion, whether "aphasia" or related terms were referred to in the article or supplemental files, eligibility criteria, consent procedures, adaptations made to support the inclusion of PwA, and attrition rates of PwA. Data were summarized, and descriptive statistics applied when appropriate.

RESULTS

271 studies comprising 215 completed RCTs and 56 protocols were included. 36.2% of included studies referred to aphasia/dysphasia. Of completed RCTs, only 6.5% explicitly included PwA, 4.7% explicitly excluded PwA, and inclusion was unclear in the remaining 88.8%. Among RCT protocols, 28.6% of studies intended inclusion, 10.7% intended excluding PwA, and in 60.7%, inclusion was unclear. In 45.8% of included studies, sub-groups of PwA were excluded, either explicitly (ie, particular types/severities of aphasia, eg, global aphasia) or implicitly, by way of ambiguous eligibility criteria which could potentially relate to a sub-group of PwA. Little rationale for exclusion was provided. 71.2% of completed RCTs did not report any adaptations that could support the inclusion of PwA, and minimal information was provided about consent procedures. Where it could be determined, attrition of PwA averaged 10% (range 0%-20%).

CONCLUSION

This paper details the extent of inclusion of PwA in stroke research and highlights opportunities for improvement.

Effectiveness of Activity-Based Task-Oriented Training on Upper Extremity Recovery for Adults With Stroke: A Systematic Review

IMPORTANCE

Interventions for improving upper extremity (UE) recovery have become a priority in stroke rehabilitation because UE disability can undermine a person's capacity to perform daily activities after stroke. A better understanding of the use of activity-based task-oriented training (TOT) will inform the development of more effective UE interventions in stroke rehabilitation.

OBJECTIVE

To examine the effectiveness of activity-based TOT in improving the UE recovery of adults with stroke.

DATA SOURCES

CINAHL Plus, MEDLINE, and PubMed.

STUDY SELECTION AND DATA COLLECTION

Inclusion criteria included quantitative studies published between June 2012 and December 2022 that reported UE recovery as an outcome, including measurements of motor function, motor performance, and performance of activities of daily living (ADLs); a sample age ≥18 yr, with stroke in all phases; and interventions that incorporated real-world daily activities. We assessed articles for inclusion, quality, and risk of bias following Cochrane methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

FINDINGS

Sixteen studies (692 participants, Level 1-4 evidence) were included. Strong to moderate evidence supported the effectiveness of activity-based TOT in UE motor function, motor performance, and ADL performance for adults with stroke. Strong evidence supported the effectiveness of hospital-based TOT, and moderate evidence supported the effectiveness of home-based TOT.

CONCLUSIONS AND RELEVANCE

The results not only showed the value of activity-based TOT as an effective UE intervention in stroke rehabilitation but also supported the occupational therapy philosophy of using functional and meaningful activities in practice. Further research on home-based TOT is needed. Plain-Language Summary: This systematic review shows the effectiveness and value of using real-life activities in task-oriented training approaches for adult survivors of stroke. The authors found strong evidence for hospital-based task-oriented training interventions and moderate evidence for home-based interventions for improving upper extremity recovery. This review shows the value of upper extremity task-oriented training as an effective intervention in stroke rehabilitation. The review also supports the occupational therapy philosophy of using functional and meaningful activities in practice as well as the profession's use of evidence-based practice in stroke rehabilitation.

Effects of the different intensities of task-oriented training on the upper extremity motor function and self-care ability of stroke survivors: study protocol for a multiarm parallel-group randomised controlled trial in a tertiary hospital in China

INTRODUCTION

Although task-oriented training (TOT) may provide added therapeutic value to stroke survivors, current TOT guidance offers insufficient advice on standardisation, particularly choices of intensity, for clinical practice. Therefore, this study aims to explore the effects of different intensities of TOT on motor function and self-care ability of stroke survivors.

METHODS AND ANALYSIS

This randomised controlled clinical trial will recruit 72 participants from a tertiary hospital, diagnosed with decreased self-care ability and upper limb motor dysfunction post-stroke. All participants will be randomly assigned to one of three experimental groups or the control group to undergo intervention for 8 weeks. The participants in the control group (n=18) will receive traditional occupational therapy, while those in the experimental groups will receive different intensities of TOT (50%, 75% and 100% intensity for groups A, B and C, respectively). This protocol designed a more innovative and optimised TOT programme to explore the optimal intensity of TOT on stroke survivors. The primary outcome is Canadian Occupational Performance Measure, and the secondary outcomes include Modified Barthel Index, Wolf Motor Function Test and Motor Activity Log.

ETHICS AND DISSEMINATION

The Second Affiliated Hospital of Hainan Medical University Ethics Committee approved the medical and ethical protocol for this study (LW2022015). All participants will sign an informed consent form. The results will be presented in scientific conferences and published in peer-reviewed journals.

Physiotherapy practices in acute and sub-acute stroke in a low resource country: A prospective observational study in Benin

BACKGROUND AND OBJECTIVE

Physiotherapy is highly recommended for early recovery from stroke. This study aimed to document physiotherapy practices for people with acute and early sub-acute stroke in Benin.

METHODS

In this prospective observational study, physiotherapists working with acute stroke people documented the content of their treatment from six hospitals in Benin during the first session, at 2-week, and 1-month post-stroke with a standardized physiotherapy documentation form. We used the motricity index (MI) and trunk control test (TCT) to assess impairments, and the 10-meter walk test (10mWT), functional independence measure (FIM), walking, stair climbing, and dressing upper body subscales were used for activity limitations.

RESULTS

Fifteen physiotherapists (60 % male, mean±SD age=31.3±5.8 years) recorded treatment sessions for 77 stroke participants (53.2 % male, mean±SD age=57.7±12.5 years). Physiotherapists focused on conventional physiotherapy approaches, including musculoskeletal (67 % of pre-functional activity time) and neuromuscular (53 % of sitting activity time) interventions. A significant difference was found between the therapy time delivered for people with mild, moderate, and severe stroke (p < 0.001). The MI (p= 0.033) and TCT (p= 0.002) measures showed significant improvement at 2-week and 1-month (p< 0.001) post-stroke, while 10mWT, FIM walking, stair climbing, and dressing upper body items significantly increased at 1-month (p< 0.001) but not at 2-week post-stroke.

CONCLUSION

Physiotherapists working with acute stroke patients in Benin mainly use conventional neuromuscular and musculoskeletal interventions. In contrast, aerobic exercises were rarely employed regardless of stroke severity. Furthermore, our findings showed that the volume of physiotherapy sessions varied by stroke severity.

Effects of motor fatigue on cortical activation level and functional connectivity during upper limb resistance training

This study aimed to clarify the effects of motor fatigue on cortical activation levels and functional connectivity during upper limb resistance training using functional near-infrared spectroscopy (fNIRS). Ten healthy college students participated in a high intensity upper limb resistance training and fNIRS was used to measure the changes of oxyhemoglobin concentration changes (HbO) in bilateral sensorimotor cortex (SMC), premotor cortex (PMC), supplementary motor area (SMA), and dorsolateral prefrontal cortex (DLPFC). The integral value (IV) of blood oxygen signal was calculated as an indicator of cortical activation level and the whole brain correlation analysis was used to calculate cortical functional connectivity. The results showed that as motor fatigue deepened, the activation levels of bilateral DLPFC and PMC in early stage were significantly higher than those in later stage (P<0.05), and the functional connectivity strength of the motor related cortex areas between the hemispheres was significantly reduced, which was manifested by the functional connectivity strength of LSMC-RSMC and LPMC-RSMC showed a significant decrease in middle stage compared with that in early stage (P<0.05) and that the functional connectivity strength of LPMC-RSMC and RSMC-SMA showed a significant decrease in later stage compared with that in early stage (P<0.05). In each stage, the motor related cortex areas maintained high activation levels and the cerebral cortex showed extensive functional connectivity.Clinical Relevance- The clinical relevance of this study is to deepen the understanding of the neural processes related to upper limb resistance training based on motor fatigue, and provide a clinical basis for optimizing resistance training strategies related to motor dysfunction patients with altered brain function under fatigue.

Task-specific training versus usual care to improve upper limb function after stroke: the "Task-AT Home" randomised controlled trial protocol

Background

Sixty percent of people have non-functional arms 6 months after stroke. More effective treatments are needed. Cochrane Reviews show low-quality evidence that task-specific training improves upper limb function. Our feasibility trial showed 56 h of task-specific training over 6 weeks resulted in an increase of a median 6 points on the Action Research Arm test (ARAT), demonstrating the need for more definitive evidence from a larger randomised controlled trial. Task-AT Home is a two-arm, assessor-blinded, multicentre randomised, controlled study, conducted in the home setting.

Aim

The objective is to determine whether task-specific training is a more effective treatment than usual care, for improving upper limb function, amount of upper limb use, and health related quality of life at 6 weeks and 6 months after intervention commencement. Our primary hypothesis is that upper limb function will achieve a ≥ 5 point improvement on the ARAT in the task-specific training group compared to the usual care group, after 6 weeks of intervention.

Methods

Participants living at home, with remaining upper limb deficit, are recruited at 3 months after stroke from sites in NSW and Victoria, Australia. Following baseline assessment, participants are randomised to 6 weeks of either task-specific or usual care intervention, stratified for upper limb function based on the ARAT score. The task-specific group receive 14 h of therapist-led task-specific training plus 42 h of guided self-practice. The primary outcome measure is the ARAT at 6 weeks. Secondary measures include the Motor Activity Log (MAL) at 6 weeks and the ARAT, MAL and EQ5D-5 L at 6 months. Assessments occur at baseline, after 6 weeks of intervention, and at 6 months after intervention commencement. Analysis will be intention to treat using a generalised linear mixed model to report estimated mean differences in scores between the two groups at each timepoint with 95% confidence interval and value of p.

Discussion

If the task-specific home-based training programme is more effective than usual care in improving arm function, implementation of the programme into clinical practice would potentially lead to improvements in upper limb function and quality of life for people with stroke.

Dosages of Swallowing Exercises Prescribed in Stroke Rehabilitation: A Medical Record Audit

This study investigated how swallowing exercise dosage is recorded, and what swallowing exercise dosages are reported in a stroke rehabilitation setting. We additionally explored the relation between mean daily swallowing repetitions and likelihood of improvement in functional swallowing status and considered how swallowing exercise dosages in practice compared to evidence-based principles of neural plasticity and strength training. We audited medical records for 42 patients with post-stroke dysphagia admitted to an inpatient rehabilitation unit over 18 months. Data were collected on participant characteristics, swallowing exercises and dosages, and clinical outcomes. The relation between dosage and outcomes was investigated using logistic regression analysis. On average, patients were seen for a median of 2.4 swallowing intervention sessions per week (IQR: 1.7) over 21 days (IQR: 16) and received a median 44.5 swallowing exercise repetitions per session (IQR: 39.6). Results indicated variable reporting of swallowing exercise dosages. Frequency, intervention duration, exercise type, and number of repetitions were routinely recorded in medical records, while intensity, session length, content, and adherence to home exercise programs were not. Frequency of swallowing intervention was lower in practice compared to research studies, and swallowing exercises did not follow specificity or progressive resistance principles. Likelihood of improvement in swallowing status was partially explained by age (B = -.015, p = .007) but not by mean daily swallowing exercise repetitions. This study illustrates dosages of swallowing exercises used in clinical practice. Results highlight the need for improved consideration and reporting of dosage, and application of evidence-based principles to swallowing exercise dosages.

Effectiveness of robot-assisted arm exercise on arm and hand function in stroke survivors - A systematic review and meta-analysis

Objective: To examine the treatment effect of commercially available robotic-assisted devices, compared to traditional occupational- and physiotherapy on arm and hand function in persons with stroke. Methods: A systematic literature search was conducted in Medline, EMBASE, CINAHL and Cochrane Central Register of Controlled Trials up to January 2022. Randomized controlled trials (RCT's) involving persons with stroke of all ages and robot-assisted exercise as method for arm and hand function, compared to traditional therapy methods were included. Three authors performed the selection independently. The quality of evidence across studies was assessed using GRADE. Results: Eighteen RCT's were included in the study. A random effects meta-analysis showed a statistically significantly higher treatment effect in the robotic-assisted exercise group (p=<0.0001) compared to the traditional treatment group, with a total effect size of 0.44 (CI = 0.22-0.65). Heterogeneity was high, measured with I2 of 65%). Subgroup analyses showed no significant effects of the type of robotic device, treatment frequency or duration of intervention. Discussion and conclusion: Even though the analysis showed significant improvement in arm and hand function in favor of the robotic-assisted exercise group, the results in this systematic review should be interpreted with caution. This is due to high heterogeneity among the studies included and the presence of possible publication bias. Results of this study highlight the need for larger and more methodological robust RCT's, with a focus on reporting training intensity during robotic exercise.

Robot-assisted therapy for upper limb paresis after stroke: Use of robotic algorithms in advanced practice

BACKGROUND

Rehabilitation of stroke-related upper limb paresis is a major public health issue.

OBJECTIVE

Robotic systems have been developed to facilitate neurorehabilitation by providing key elements required to stimulate brain plasticity and motor recovery, namely repetitive, intensive, adaptative training with feedback. Although the positive effect of robot-assisted therapy on motor impairments has been well demonstrated, the effect on functional capacity is less certain.

METHOD

This narrative review outlines the principles of robot-assisted therapy for the rehabilitation of post-stroke upper limb paresis.

RESULTS

A paradigm is proposed to promote not only recovery of impairment but also function.

CONCLUSION

Further studies that would integrate some principles of the paradigm described in this paper are needed.

The Effect of Task-Oriented Activities Training on Upper-Limb Function, Daily Activities, and Quality of Life in Chronic Stroke Patients: A Randomized Controlled Trial

This randomized controlled study aimed to investigate the effects of 8-week task-oriented activities of daily living (T-ADL) training on upper limb functions, activities of daily living (ADL), and quality of life (QoL) in chronic stroke patients. The 33 patients were randomly assigned to the T-ADL training or conventional occupational therapy (OT) group. The respective interventions were provided for 45-min a day, five times a week for eight weeks. To compare the upper-limb function before and after the intervention, the manual function test (MFT), box and block test (BBT), and grasp power test were performed; to compare the level of ADL performance, the modified-Barthel index (MBI) was measured. To evaluate QoL, stroke-specific QoL was measured. There was a significant group-by-time interaction in the affected side MFT score and both sides of BBT scores, but no significant interaction was found in the unaffected side MFT score, ADL, and QoL. Both groups showed a significant main effect of time in their ADL and QoL after the intervention (p < 0.001). The results of this study indicate that the eight-week T-ADL training has a positive effect on upper limb functions and gross manual dexterity, and both T-ADL training and conventional OT are effective in improving ADL and QoL in chronic stroke patients.

Art skill-based rehabilitation training for upper limb sensorimotor recovery post-stroke: A feasibility study

Objective

The objective of this study was to assess the feasibility of delivering Art skill-based Rehabilitation Training (ART), a novel upper limb motor training program, to patients with stroke as an adjunct to standard care in an inpatient setting.

Design

Feasibility study.

Setting

Inpatient stroke rehabilitation unit at a university hospital.

Participants

Thirty-eight patients admitted to a stroke rehabilitation unit with upper limb motor impairment were enrolled in the ART program facilitated by trained non-healthcare professionals between December 2017 and June 2021.

Intervention

The ART program included nine, one-hour sessions of supervised tracing and freehand drawing tasks completed with both hands. This program was intended to be delivered at a frequency of three times per week over a duration of 3 weeks or for the length of inpatient stay.

Main outcome measures

Feasibility outcomes included ART program adherence, acceptability, and safety.

Results

Thirty-two (84%) participants with subacute stroke completed the ART program and 30 (79%) were included in the study analysis. Participants completed 93–100% of the ART tasks in a median [IQR] of 8 [6–10] ART sessions over a median [IQR] duration of 15 [7–19] days. ART program facilitators effectively provided upper limb assistance to patients with more severe upper limb impairments. Adherence and acceptability were high and no study-related adverse events occurred.

Conclusion

The ART program was feasible to deliver and highly acceptable to patients with stroke. Further research is warranted to explore the impact of ART on upper limb sensorimotor function and use.

Somesthetic, Visual, and Auditory Feedback and Their Interactions Applied to Upper Limb Neurorehabilitation Technology: A Narrative Review to Facilitate Contextualization of Knowledge

Reduced hand dexterity is a common component of sensorimotor impairments for individuals after stroke. To improve hand function, innovative rehabilitation interventions are constantly developed and tested. In this context, technology-based interventions for hand rehabilitation have been emerging rapidly. This paper offers an overview of basic knowledge on post lesion plasticity and sensorimotor integration processes in the context of augmented feedback and new rehabilitation technologies, in particular virtual reality and soft robotic gloves. We also discuss some factors to consider related to the incorporation of augmented feedback in the development of technology-based interventions in rehabilitation. This includes factors related to feedback delivery parameter design, task complexity and heterogeneity of sensory deficits in individuals affected by a stroke. In spite of the current limitations in our understanding of the mechanisms involved when using new rehabilitation technologies, the multimodal augmented feedback approach appears promising and may provide meaningful ways to optimize recovery after stroke. Moving forward, we argue that comparative studies allowing stratification of the augmented feedback delivery parameters based upon different biomarkers, lesion characteristics or impairments should be advocated (e.g., injured hemisphere, lesion location, lesion volume, sensorimotor impairments). Ultimately, we envision that treatment design should combine augmented feedback of multiple modalities, carefully adapted to the specific condition of the individuals affected by a stroke and that evolves along with recovery. This would better align with the new trend in stroke rehabilitation which challenges the popular idea of the existence of an ultimate good-for-all intervention.

Zakaria H, M. Ragab W, Al Awaji NN, Y. Elzanaty M, R. Elserougy H. Therapeutic Efficacy of Transcutaneous Electrical Nerve Stimulation Acupoints on Motor and Neural Recovery of the Affected Upper Extremity in Chronic Stroke: A Sham-Controlled Randomized Clinical Trial

Inability to use the affected upper extremity (UE) in daily activities is a common complaint in stroke patients. The somatosensory system (central and peripheral) is essential for brain reorganization and plasticity. Neuromuscular electrical stimulation is considered an effective modality for improving UE function in stroke patients. The aim of the current study was to determine the therapeutic effects of transcutaneous electrical nerve stimulation (TENS) acupoints on cortical activity and the motor function of the affected UE in chronic stroke patients. Forty male and female patients diagnosed with stroke agreed to join the study. They were randomly assigned to group 1 (G1) and group 2 (G2). G1 received task-specific training (TST) and sham electrical stimulation while G2 received TST in addition to TENS acupoints. Session duration was 80 min. Both groups received 18 sessions for 6 successive weeks, 3 sessions per week. Evaluation was carried out before and after completion of the treatment program. Outcome measures used were the Fugl-Meyer Assessment of the upper extremity (FMA-UE) and the box and block test (BBT) as measures of the motor function of the affected UE. Brain activity of the motor area (C3) in the ipsilesional hemisphere was measured using a quantitative electroencephalogram (QEEG). The measured parameter was peak frequency. It was noted that the motor function of the affected UE improved significantly post-treatment in both groups, while no significant change was reported in the FMA-UE and BBT scores post-treatment in either G1 or G2. On the other hand, the activity of the motor area C3 improved significantly in G2 only, post-treatment, while G1 showed no significant improvement. There was also significant improvement in the activity of the motor area (C3) in G2 compared to G1 post-treatment. The results of the current study indicate that TST only or combined with TENS acupoints can be considered an effective method for improving motor function of the affected UE in chronic stroke patients, both being equally effective. However, TST combined with TENS acupoints proved better in improving brain plasticity in chronic stroke patients.

Pain mapping and characteristics in breast cancer survivors during task-oriented training: analysis at 3, 6, and 9 months

PURPOSE

To evaluate the frequency and characteristics of trunk and upper limb pain in women diagnosed with breast cancer, in different movement planes, during task-oriented training (TOT) 3, 6, and 9 months after surgery.

METHODS

A prospective cohort study with 20 women. The body pain diagram (BPD), VAS, and McGill questionnaire were used. The TOT consisted of 20 exercises based on the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) questionnaire. BPD overlay was performed in GIMP® image editor. The chi-square test was applied to the relationship between population characteristics and pain. Freedman's ANOVA and the Cochran's Q test were used in the comparison of pain site frequencies and intensity over time.

RESULTS

In total, 297 BPDs were generated, which identified the affected upper limb as the body area with the highest frequency of pain at the three moments. However, at 9 months, the unaffected upper limb presented the same frequency as the affected limb. Radiotherapy presented a statistically significant relationship (p < 0.05) with pain at 9 months. The pain was characterized as moderate at the three moments, affective at 3 and 6 months, and sensory at 9 months.

CONCLUSION

The most frequent area of pain at 3 and 6 months was the affected upper limb however, at 9 months, the unaffected upper limb presented the same frequency of pain as the affected upper limb. Pain was characterized as moderate at the three evaluation moments.

Effect of Task-Specific Training on Trunk Control and Balance in Patients with Subacute Stroke

Objectives

Impairment of static and dynamic posture control is common after stroke. It is found to be a predictor and an essential component for balance, walking ability, and activities of daily living (ADL) outcomes. Studies investigating effect of physical therapy techniques with an aim to improve trunk function after stroke are limited. This study aimed at studying the effect of task-specific training on trunk control and balance in patients with subacute stroke.

Methods

In this randomized controlled trail, thirty-four patients were alienated into two equal groups. The study group (n = 17) received task-specific training, and the control group (n = 17) received conventional physical therapy based on the neurodevelopmental technique. Task-specific training was applied through two phases with criteria of progression based on Chedoke-McMaster Stroke Assessment postural control stages. The interventions were applied in a dosage of 60 min per session, three times a week for ten weeks. Static and dynamic balance were measured by the trunk impairment scale (TIS), postural assessment scale (PAS), and functional reach test (FRT). Laser-guided digital goniometer was used to measure the trunk ranges of motions (ROM) as a secondary outcome.

Results

Significant differences between the baseline and the follow-up measures including TIS, PAS, FRT, and trunk (ROM) were found in both groups (P ≤ 0.05). In-between group comparison also showed significant differences between the results of both groups indicating more improvements among patients representing the study group.

Conclusion

Task-specific training may be effective in improving the static and dynamic postural control and trunk ranges of motion among subacute stroke patients.

A Comparative Study on the Effect of Task Specific Training on Right Versus Left Chronic Stroke Patients

Functional impairment of the upper limb (UL) after stroke is a great problem. Finding methods that can improve UL function after stroke is a major concern to all medical service providers. This study was intended to compare the effect of upper limb task specific training (TST) on brain excitability of the affected hemisphere and motor function improvements in patients with left and right stroke. Forty male patients with mild impairment of UL functions were divided into two equal groups; G1 consisted of patients with left hemisphere affection (right side stroke) while G2 consisted of patients with right hemisphere affection (left side stroke). All patients received TST for the affected UL for one hour, three sessions per week for six consecutive weeks. Evaluation was performed twice, pre-, and post-treatment. Outcome measures used were Wolf Motor Function Test (WMFT) and Box and Block Test (BBT) as measures of UL motor function and Quantitative Electroencephalogram (QEEG) of motor and sensory areas of the affected hemisphere as a measure of brain reorganization post-stroke. Both groups showed improvement in motor function of the affected UL measured by WMFT and BBT with reported significant difference between them. G1 showed greater improvement in motor function of the affected UL post-treatment compared to G2. Additionally, there was a significant increase in peak frequency of motor and sensory areas with higher and significant excitability in G1 only. These findings imply that brain reorganization in the left hemisphere responded more to TST compared to the right hemisphere. Based on findings of the current study, we can recommend adding TST to the physical therapy program in stroke patients with left hemisphere lesions.

Influence of task-oriented circuit training on upper limb function among rural community-dwelling survivors of stroke

Background

Task-oriented circuit training using a Multi-Activities workstation emphasises goal-oriented tasks practiced in a circuit or series in order to learn a new skill. It can be used for upper limb rehabilitation among stroke patients in a community setting, but there is currently very little evidence available regarding its use in this patient group and setting. This study aimed to explore the influence of task-oriented circuit training using a Multi-Activities workstation on upper limb function among community-dwelling individuals with chronic stroke.

Methods

A pre-test–post-test study was conducted involving 17 community-dwelling individuals with chronic stroke who were attending a stroke rehabilitation centre. Six weeks of task-oriented circuit training was given using a Multi-Activities workstation aimed to improve strength, range of motion and dexterity. Streamlined Wolf Motor Function Test and Chedoke Arm and Hand Activity Inventory were used to measure outcomes. Wilcoxon signed-rank test was used for data analysis.

Results

A total of 12 sessions of task-oriented circuit training using Multi-Activities workstations did not result in any statistically significant differences in outcome measures.

Conclusions

Task-oriented circuit training using the Multi-Activities workstation did not improve upper limb function in community-dwelling individuals with chronic stroke.

The Hua-Shan rehabilitation program after contralateral seventh cervical nerve transfer for spastic arm paralysis

Purpose: To propose the novel Hua-Shan rehabilitation program for patients undergoing the contralateral seventh cervical nerve transfer, and explore the influence of different rehabilitation on the postoperative recovery.Materials and methods: The Hua-Shan program was established in consideration of the three elements: the nerve regeneration, brain plasticity and group therapy. Its effect was evaluated by comparing the postoperative recovery of the hemorrhagic stroke survivors among the following three groups: Group A-standard Hua-Shan program after surgery; Group B-standard traditional program after surgery; Group C-no standard rehabilitation after surgery.Results: Significantly better functions after surgery were detected in all the groups, while the absence of standard rehabilitation massively offset the benefits of the surgery. Furthermore, the Hua-Shan program showed advantage over the traditional rehabilitation, which may largely be attributed to its improvements for the fine action of wrist&finger.Conclusions: The Hua-Shan program provided the opportunity to maximize the benefits of contralateral seventh cervical nerve transfer.IMPLICATIONS FOR REHABILITATIONStandard rehabilitation plays key roles in the recovery process for patients undergoing contralateral seventh cervical nerve transfer.The Hua-Shan program targeting nerve regeneration, brain plasticity and group therapy further improved the benefits of patients undergoing contralateral seventh cervical nerve transfer.
