Feasibility of accelerometry in a self-directed upper limb activity program of a subacute setting with stroke survivors.

Background Wearable devices, such as accelerometers, offer novel approaches to measuring post-stroke upper limb activity. Limited studies have explored feasibility of accelerometry. Guided by the Bowen Feasibility Framework, this feasibility study aimed to examine the practicality, acceptability, and limited efficacy of accelerometry in a self-directed upper limb program with stroke survivors using a pre-post study of sequentially eligible inpatients. Method Key metrics were: practicality (60% of participants had 10hours of wear per day for 3 or more days), acceptability (adherence to recommended wear-time), and limited efficacy (correlation between Wolf Motor Function Test (WMFT) and upper limb use from accelerometry data). Results Twelve stroke survivors were recruited over 7 months, mean age 73years (range 39-94years). Eight participants (67%) met the practicality and acceptability criteria. A moderate positive correlation existed between WMFT and upper limb use at admission (r s =0.33, P =0.42) and at discharge (r s =0.42, P =0.34). Conclusion Wearable devices were feasible and acceptable for most stroke survivors, however, one-third found the devices uncomfortable, and this should be factored into sample size calculations of future studies.

Case report: A novel transcutaneous electrical nerve stimulation improves dysesthesias and motor behaviors after transverse myelitis

PurposeTransverse myelitis (TM)-associated dysesthesia is diverse and frequently resistant to treatment. This study explored the comprehensive effects of a novel transcutaneous electrical nerve stimulation (TENS) approach tailored to an individual’s specific dysesthesia profile in a patient with TM.Patient and methodA 52-year-old woman with severe dysesthesias in the left C8 sensory area caused by TM underwent an A-B-A-B-A design intervention. The baseline (phase A) and intervention (phase B) phases were both 7 days. Tingling and allodynia were scored on an 11-point numerical rating scale pre-, post-, and 1 h post-treatment. Upper limb activities during daily living were assessed using a wrist-worn accelerometer. The intervention phase consisted of 60-min sessions of TENS two times daily. Furthermore, the intervention and carry-over effects of TENS were evaluated using Tau-U and Bayesian unknown change point models.ResultsThe effects of TENS resulted in the immediate improvement in tingling, allodynia, and upper limb activity. Long-term effects of TENS affected tingling and upper limb activity; however, no impacts on allodynia were observed.ConclusionThis novel TENS approach shows promise as an effective treatment, even in rare and treatment-resistant dysesthesia associated with TM.

Diminished sense of agency inhibits paretic upper-limb use in patients with post-stroke motor deficits

Post-stroke motor deficits often disrupt the voluntary control of body movements, leading to abnormal feelings. Among these, alterations in the sense of agency (SoA), the feeling of controlling one’s movement, are notable because SoA facilitates actions. However, whether patients with more severe motor deficits experience poorer SoA and SoA’s clinical impact on motor activity remain unclear. To address these questions, this longitudinal study quantified SoA in 156 post-stroke patients through factor analyses with multiple question items to differentiate SoA from potentially confounding discomfort. Structural equation modeling revealed that SoA decreased significantly with upper-limb motor deficit severity and that reduced SoA correlated significantly with decreased paretic upper-limb use. Notably, this effect persisted after controlling for motor deficit severity, suggesting a direct clinical impact of SoA on motor activity. Further, improvements in SoA were significantly associated with increased upper-limb use in patients with moderate or severe motor deficits, emphasizing the role of SoA in maintaining or increasing paretic upper-limb activity. These findings highlight the importance of rehabilitation treatments that consider patients’ subjective experiences, particularly agency attribution.

Effect of serious games over conventional therapy in the rehabilitation of people with multiple sclerosis – a systematic review and meta-analysis

Purpose This meta-analysis aimed to quantify the effect of serious games over conventional therapy on upper-limb activity, balance, gait, fatigue, and cognitive functions in people with multiple sclerosis. Materials and methods Search strategies were developed for PubMed, Embase, Cochrane Library, and Scopus. Studies were selected if participants were adults with multiple sclerosis; the intervention consisted of a virtual reality serious game-based program; the control group received conventional therapy; outcomes included upper limb activity, balance, gait, fatigue, or cognitive functions; and used a randomized controlled trial design. Data were synthesized using a standardized mean difference with a random-effects model. Results From 2532 studies, seventeen trials were selected (n = 740). Overall, serious games programs effect on upper limb activity, gait, verbal memory, verbal fluency and attention seemed neutral. Balance functions appeared to be improved by semi-immersive virtual reality serious games (SMD = 0.48;95%CI = 0.12–0.84;p = 0.01;I2=0%), fatigue by treadmill serious games (SMD = 0.80;95%CI = 0.40–1.20;p < 0.001) and visuo-spatial memory by semi-immersive virtual reality general cognitive serious games (SMD = 0.35;95%CI = 0.04–0.65;p = 0.03;I2=0%). Conclusion This review suggests, with a very-low-to-low certainty of evidence, that while some specific serious games may improve balance, fatigue and visuo-spatial memory, their overall effect on upper limb activity, gait, and other cognitive functions appears neutral.

Application of a Dual Upper Limb Task-Oriented Robotic System for the Functional Recovery of the Upper Limb in Stroke Patients.

Highly repetitive and task-oriented training has been shown to promote the recovery of limb function in stroke patients. Additionally, bilateral arm training can help stroke survivors regain their upper limb function and improve their daily activities. The dual upper limb task-oriented robotic system is designed to assist the healthy side of the stroke patient in driving the affected side to perform bilateral arm training through the use of a robotic device. It can also guide the patient in carrying out dual upper limb coordinated movements and engage them in a task-oriented virtual game using force feedback and human-computer interaction technology. This study aimed to assess the efficacy of the system in enhancing upper limb function and activities of daily living in stroke patients. The assessment methods used included motor evoked potential (MEP), functional test for the hemiplegic upper extremity-Hong Kong (FTHUE-HK), Fugl-Meyer Assessment Upper Extremity Scale (FMA-UE), and modified Barthel index (MBI). The results of the study indicate that the dual upper limb task-oriented robotic system can significantly improve the corticospinal pathway, upper limb function, and activities of daily living in stroke patients after 6 weeks of treatment. This system can serve as an effective adjunct to upper limb functional rehabilitation in stroke survivors, reducing the dependence on rehabilitation therapists. In conclusion, the dual upper limb task-oriented robotic system provides a new strategy for post-stroke limb functional rehabilitation and holds great potential for application, as it offers certain social and financial benefits.

Effect of intermittent theta burst stimulation on upper limb function in stroke patients: a systematic review and meta-analysis.

Stroke is a serious health issue that affects individuals, families, and society. Particularly, the upper limb dysfunction caused by stroke significantly reduces the quality of life for patients and may lead to psychological issues. Current treatment modalities are not fully effective in helping patients regain upper limb motor function to optimal levels. Therefore, there is an urgent need to explore new rehabilitation methods to address this issue. The purpose of this meta-analysis and systematic review is to explore the effects of intermittent theta burst stimulation (iTBS) on upper limb function in stroke patients. We searched PubMed, Cochrane Library, Embase, Web of Science, PEDro and China National Knowledge Internet as of April 8, 2024. Retrieved a total of 100 articles. Standardized mean differences (SMDs) and 95% confidence intervals (CI) were calculated. The study included a total of 9 trials and involved 224 patients. The results demonstrate that compared to the control group, iTBS therapy significantly improved Fugl-Meyer assessment-upper extremity (FMA-UE) scores (SMD = 0.88; 95% CI = 0.11-1.66; P = 0.03, I 2 = 84%), Action Research Arm Test (ARAT) scores (SMD = 0.83; 95% CI = 0.16-1.50; P = 0.02, I 2 = 57%), and Barthel Index (BI) scores (SMD = 0.93; 95% CI = 0.53-1.32; P < 0.0001, I 2 = 0%) in stroke patients. The comprehensive evidence suggests that iTBS has superior effects in improving upper limb function and activities of daily living in stroke patients.

Effect of modified constraint-induced movement therapy along with bimanual massed practice on upper extremity functions in tetraplegics: a pilot study

Background and objectiveConstraint-induced movement therapy is a widely used rehabilitation program in the stroke population, but its application in spinal cord injury is limited. The objective of the study is to determine the feasibility of modified constraint-induced movement therapy (mCIMT) in incomplete tetraplegia exhibiting upper limb weakness and activities of daily living (ADLs) difficulty.MethodThis is a quasi-experimental one-group pilot study, consisting of 12 subjects diagnosed with incomplete tetraplegia. They received 2-h sessions of modified constraint-induced movement therapy of the weaker hand along with a 1-h session of bimanual massed practice, 5 days a week for 3 weeks. Apart from this, they were asked to do 3 h of constrained-induced movement therapy daily 5 days a week for 3 weeks at their home as a part of a home exercise program. Box and block test (BBT) and Spinal Cord Independence Measure version III (SCIM-III) were taken as the primary measure, and manual function test (MFT) and capabilities for upper extremity (CUE) were used as secondary measures to access hand functions and ADLs. Subjects were examined during pre-intervention and post-intervention.ResultsAfter 3 weeks of intervention, the mean change of the score for the trained hand showed significant changes in the scores of the box and block test (p = 0.03), manual function test (p = 0.02), SCIM-III (p = 0.03), and CUE (p = 0.02).ConclusionThis preliminary study revealed that modified CIMT may be a feasible and effective alternative for hand rehabilitation in incomplete tetraplegia.

How does moderate upper limb activity modify sitting forces for able-bodied persons and wheelchair users?

Introduction Most people with a spinal cord injury are concerned by pressure injuries (PrI). Since dynamic activities may involve distributions of forces over time that are different from static and given the significant impact of PrIs on healthcare costs, it is, important to study these sitting forces. We aim to investigate sitting forces (overall normal, shear forces and Peak Pressure Index (PPI)) assessed in both able-bodied and wheelchair users (WCU) under static and dynamic conditions. Our hypothesis is that wheelchair sitting forces encountered by able-bodied participants are significantly different from those of WCUs. Material and Methods An experimental seat and a pressure mapping system were used to investigate forces in two different populations, 102 able-bodied and 15 WCUs, in static conditions and during synchronised hand-cycling. The analysis includes statistical comparisons of the sitting conditions (static/dynamic) and of the populations (able-bodied/WCUs). Results and discussion Significant differences in normal forces and PPI were observed between able-bodied and WCUs; conversely, differences in shear forces were non-significant. This suggests that contrary to shear forces, no conclusion on normal forces drawn from trials with healthy participants can directly be applied to WCUs. Secondly, the present results indicate significant reduced averaged: normal force, PPI, and shear forces for able-bodied performing a dynamic activity compared to static sitting. WCUs experienced non-significant lower averaged normal force and PPI but significant lower averaged shear forces. Conclusion While the present results seem to indicate lower forces for able-bodied performing a dynamic activity compared to static sitting, due to reduced averaged forces, this conclusion is less clear-cut for WCUs.

Feasibility of a home-based home videogaming intervention with a family-centered approach for children with cerebral palsy: a randomized multiple baseline single-case experimental design

BackgroundWorldwide, children with cerebral palsy (CP) living in underserved communities face barriers to accessing motor therapy services. This study assessed the implementation and effectiveness of an 8-week, upper limb (UL) home-based intervention with a movement-tracking videogame (Bootle Blast) in Costa Rican children with CP.MethodsChildren established a weekly playtime goal and two UL activities of daily living (ADLs) that they would like to improve on. A multiple-baseline, single-case experimental design, was used with the Performance Quality Rating Scale (PQRS) as the repeated measure to track changes in performance of the selected ADLs between the baseline (usual care) and intervention (Bootle Blast) phases. The Canadian Occupational Performance Measure (COPM), the Box and Blocks Test (BBT) and the Children’s Hand-Use Experience Questionnaire (CHEQ) were collected before and after the intervention. Technical barriers were documented during weekly video calls with a monitoring therapist. Treatment effect size, slope changes and percentage of non-overlapping data were identified for the PQRS. Descriptive statistics summarized results for the BBT, CHEQ, videogame logs (e.g., playtime) and technical barriers.ResultsFifteen children participated and 13 completed the intervention. Both participants who dropped out did so after completing baseline assessments, but before experiencing Bootle Blast. Children’s mean active playtime (i.e., mini-games targeting the UL) across the 8-weeks was 377 min, while mean total time spent engaging with Bootle Blast (active + passive play time [e.g., time navigating menus, reviewing rewards]) was 728 min. In total, eight technical issues (from five children) were reported, and all but three were resolved within 48 h. Partial effectiveness was associated with the intervention. Specifically, 85% of participants improved on the PQRS and 69% achieved clinically important improvements ≥ 2 points in performance on the COPM. Children improved by 1.8 blocks on average on the BBT, while on the CHEQ, five children had a clinically important increase of 10% of the total number of UL activities performed with both hands.ConclusionBootle Blast is a feasible and effective option to facilitate access and engage children with cerebral palsy in UL home rehabilitation.Trial registration Trial registration number: NCT05403567.

Genetic polymorphisms and post-stroke upper limb motor improvement - A systematic review and meta-analysis.

Post-stroke upper limb (UL) motor improvement is associated with adaptive neuroplasticity and motor learning. Both intervention-related (including provision of intensive, variable, and task-specific practice) and individual-specific factors (including the presence of genetic polymorphisms) influence improvement. In individuals with stroke, most commonly, polymorphisms are found in Brain Derived Neurotrophic Factor (BDNF), Apolipoprotein (APOE) and Catechol-O-Methyltransferase (COMT). These involve a replacement of cystine by arginine (APOEε4) or valines by 1 or 2 methionines (BDNF:val66met, met66met; COMT:val158met; met158met). However, the implications of these polymorphisms on post-stroke UL motor improvement specifically have not yet been elucidated. Examine the influence of genetic polymorphism on post-stroke UL motor improvement. Systematic Review and Meta-Analysis. We conducted a systematic search of the literature published in English language. The modified Downs and Black checklist helped assess study quality. We compared change in UL motor impairment and activity scores between individuals with and without the polymorphisms. Meta-analyses helped assess change in motor impairment (Fugl Meyer Assessment) scores based upon a minimum of 2 studies/time point. Effect sizes (ES) were quantified based upon the Rehabilitation Treatment Specification System as follows: small (0.08-0.18), medium (0.19 -0.40) and large (≥0.41). We retrieved 10 (4 good and 6 fair quality) studies. Compared to those with BDNF val66met and met66met polymorphism, meta-analyses revealed lower motor impairment (large ES) in those without the polymorphism at intervention completion (0.5, 95% CI: 0.11-0.88) and at retention (0.58, 95% CI:0.06-1.11). The presence of CoMT val158met or met158met polymorphism had similar results, with lower impairment (large ES ≥1.5) and higher activity scores (large ES ranging from 0.5-0.76) in those without the polymorphism. Presence of APOEε4 form did not influence UL motor improvement. Polymorphisms with the presence of 1 or 2 met alleles in BDNF and COMT negatively influence UL motor improvement. https://osf.io/wk9cf/.

Evaluation of upper limb perception after stroke with the new Affected Limb Perception Questionnaire (ALPQ): a study protocol

BackgroundFollowing a stroke, patients may suffer from alterations in the perception of their own body due to an acquired deficit in body representations. While such changes may impact their quality of life as well as recovery, they are not systematically assessed in clinical practice. This study aims at providing a better understanding of the rate, evolution, and impact on recovery of upper limb (UL) body perceptions (BPs) alterations following stroke. In addition, we will investigate associations among BPs alterations items, their associations with the sensorimotor functions, UL activity, damages in brain structure and connectivity.MethodsWe developed a new tool named ALPQ (for Affected Limb Perception Questionnaire) to address the present study objectives. It assesses subjective alterations in the perception of the affected UL following stroke, by measuring several dimensions, namely: anosognosia for hemiplegia, anosodiaphoria for hemiplegia, hemiasomatognosia, somatoparaphrenia, personification of the affected limb, illusion of modification of physical characteristics (temperature, weight, length), illusory movements, super- or undernumerary limb, UL disconnection, misoplegia, and involuntary movement. This study combines a cross-sectional and longitudinal design. The completed data sample will include a minimum of 60 acute and 100 sub-acute stroke patients. When possible, patients are followed up to the chronic stage. Complementary evaluations are administered to assess patients’ sensorimotor and cognitive functions as well as UL activity, and brain lesions will be analysed.DiscussionThis study will provide a better understanding of BPs alterations following stroke: their rate and evolution, as well as their associations with sensorimotor deficit, cognitive profile and UL activity, brain lesions and recovery. Ultimately, the results could support the personalization of rehabilitation strategy according to patients’ UL perception to maximize their recovery.Study registrationThe protocol for this study has been pre-registered on the Open Science Framework on July the 7th, 2021: https://osf.io/p6v7f.

Effects of Upper Limb Control on the Less-Affected Side on Upper Limb Function, Respiration, Balance, and Activities of Daily Living in Stroke.

Background and Objectives: This study aimed to investigate the effects of upper limb control exercises on upper limb function, respiration, balance, and activities of daily living in patients with stroke. Materials and Methods: The 28 patients who met the selection criteria were randomly assigned to two groups of 14 patients each. Subsequently, upper limb control exercises using real-time feedback were applied. The same interventional exercise was applied to both the less-affected and affected limbs of the study participants, who were classified into a less-affected side upper limb control group and an affected side upper limb control exercise group. Interventional exercises, 30 min each, were performed five times weekly for 4 weeks, and follow-up examinations were performed 2 weeks after the end of exercise. Electronic muscle strength measurements and an electronic goniometer were used to evaluate upper limb function. A spirometer was used to measure respiration. Balance ability was evaluated using a force plate pressure distribution measuring system with a sensor that detects the movement of the body center on the ground. Daily life movements were evaluated using the Korean version of the modified Barthel index. Results: When examining the results, the upper limb function on the paralyzed side showed an increase in the electromyographic strength of shoulder joint depression and flexion angle. Improvements were also observed in respiration (forced vital capacity [L] and forced expiratory volume in 1 s [L]), balance (95% confidence ellipse area [mm2] and center of pressure displacement [mm]), and daily life activities, all of which showed statistically significant differences in the time × group interaction effect (p < 0.05). Conclusions: Thus, it was found that the upper limb control exercise on the less-affected side had a significant effect when the exercise was performed together with treatment on the affected side in patients with stroke. It is anticipated that this study will provide basic data for evaluating both the trunk and upper limbs of the less-affected and affected sides.

Effectiveness of virtual reality-supported exercise therapy in improving upper extremity function and activities of daily living among patients after stroke: a systematic review of randomized control trials.

This systematic review describes the effectiveness of virtual reality (VR)-supported exercise therapy on upper limb motor function and activities of daily living after stroke. Studies published through January 24, 2022, were identified using CINAHL, Cochrane Library, Embase, Medline, and Web of Science. Randomized control trials comparing VR treatment with conventional therapy (CT) for upper extremity rehabilitation after stroke were included. Methodological quality was assessed using the Cochrane risk-of-bias tool. Of 9 included studies, 5 concluded that the VR group outperformed control participants, 1 indicated the superiority of VR-supported exercises alone over CT, and 3 found VR comparable to CT in promoting upper limb motor function. Five studies analyzed independence in daily living, with 4 reporting no significant difference between VR and CT groups. No strong evidence indicated long-term benefits of VR-assisted exercise. All included studies demonstrated low risk of bias concerning random sequence generation, allocation concealment, outcome assessment blinding, incomplete outcome data, and selective reporting bias. However, a high risk of bias was observed regarding participant blinding due to the nature of the intervention. Most studies suggested that VR, used alongside CT, can improve motor function following stroke. However, the evidence was insufficient to conclude that VR outperforms conventional approaches.

A gamified social robotics platform for intensive therapies in neurorehabilitation

The use of social assistive robots for interactive stimulation has strong potential in neurorehabilitation therapies. It is of particular interest in the case of pediatric patients to promote children’s motivation and adherence, specially when those robots are able of guide gamified activities, as it is the case of NAOTherapist. NAOTherapist is a Social Assistive Robotics (SAR) platform for hands-off rehabilitation based on upper-limb activities, that was originally designed for pediatric patients with Cerebral Palsy (CP) or Obstetric Braxial Plexus Palsy (OBPP). Formerly, it endowed the therapists with tools to perform rehabilitation exercises. This paper proposes the gamification of NAOTherapist in order to incorporate additional characteristics which allow its intensive use in new rehabilitation procedures, such as the Hand-Arm Bimanual Intensive Therapy (HABIT). This intensive therapy setting involves daily activities in several consecutive days, which require a strong engagement of the patients with the therapeutic methods and the acceptation of the NAOTherapist as a rehabilitation system. The gamified system shows very accurate results considering the different aspects defined in the USUS methodology; namely Usability, Social acceptance, User experience and Societal impact.

Post-Stroke Impairments of Manual Dexterity and Finger Proprioception: Their Contribution to Upper Limb Activity Capacity

Background Knowing how impaired manual dexterity and finger proprioception affect upper limb activity capacity is important for delineating targeted post-stroke interventions for upper limb recovery. Objectives To investigate whether impaired manual dexterity and finger proprioception explain variance in post-stroke activity capacity, and whether they explain more variance than conventional clinical assessments of upper limb sensorimotor impairments. Methods Activity capacity and hand sensorimotor impairments were assessed using clinical measures in N = 42 late subacute/chronic hemiparetic stroke patients. Dexterity was evaluated using the Dextrain Manipulandum to quantify accuracy of visuomotor finger force-tracking (N = 36), timing of rhythmic tapping (N = 36), and finger individuation (N = 24), as well as proprioception (N = 27). Stepwise multivariate and hierarchical linear regression models were used to identify impairments best explaining activity capacity. Results Dexterity and proprioceptive components significantly increased the variance explained in activity capacity: (i) Box and Block Test was best explained by baseline tonic force during force-tracking and tapping frequency (adjusted R2 = .51); (ii) Motor Activity Log was best explained by success rate in finger individuation (adjusted R2 = .46); (iii) Action Research Arm Test was best explained by release of finger force and proprioceptive measures (improved reaction time related to use of proprioception; adjusted R2 = .52); and (iv) Moberg Pick-Up test was best explained by proprioceptive function (adjusted R2 = .18). Models excluding dexterity and proprioception variables explained up to 19% less variance. Conclusions Manual dexterity and finger proprioception explain unique variance in activity capacity not captured by conventional impairment measures and should be assessed when considering the underlying causes of post-stroke activity capacity limitations.

How does a motor or cognitive dual-task affect our sense of upper limb proprioception?

Daily upper limb activities require multitasking and our division of attention. How we allocate our attention can be studied using dual-task interference (DTi). Given the vital role proprioception plays in movement planning and motor control, it is important to investigate how conscious upper limb proprioception is impacted by DTi through cognitive and motor interference. To examine how dual-task interference impacts conscious upper limb proprioception during active joint repositioning tasks (AJRT). Forty-two healthy participants, aged between 18 and 35, took part in this cross-sectional study. Participants completed two AJRT during three conditions: baseline (single task), dual-cognitive task (serial subtractions), and dual-motor task (non-dominant hand movements). The proprioceptive error (PE; difference between their estimation and targeted position) was measured using an AJRT of 75% and 90% of maximum internal rotation using the Biodex System IIITM and the Upper Limb Proprioception Reaching Test (PRO-Reach). To determine if PEs differed during dual-task interference, interference change scores from baseline were used with one sample t-tests and analyses of variance. The overall mean PE with the Biodex was 4.1° ± 1.9 at baseline. Mean change scores from baseline reflect a mean improvement of 1.5° ± 1.0 (p < .001) during dual-cognitive task and of 1.5° ± 1.2 (p < .001) during dual-motor task. The overall mean PE with the PRO-Reach was 4.4cm ± 1.1 at baseline. Mean change scores from baseline reflect a mean worsening of 1.0cm ± 1.1 (p < .001) during dual-cognitive task and improvement of 0.8cm ± 0.6 (p < .001) during dual-motor task. Analysis of variance with the Biodex PEs revealed an interference effect (p < .001), with the cognitive condition causing greater PEs compared to the motor condition and a criterion position effect (p = .006), where 75% of maximum IR produced larger PEs during both interference conditions. An interference effect (p = .022) with the PRO-Reach PEs was found highlighting a difference between the cognitive and motor conditions, with decreased PEs during the contralateral motor task. Interference tasks did impact proprioception. Cognitive interference produced mixed results, whereas improved proprioception was seen during motor interference. Individual task prioritization strategies are possible, where each person may choose their own attention strategy when faced with dual-task interference.

Post-stroke treatment - use of virtual reality as aid in motor rehabilitation

This study describes the use of Virtual Reality (VR) therapy in the rehabilitation of patients after suffering from a cerebrovascular accident (CVA) who had motor sequelae. Several studies were presented showing that the use of VR as a rehabilitation tool can bring significant benefits in improving the motor function of patients. Introducing different elements into therapy, such as task-specific practice, explicit feedback, increasing difficulty, implicit feedback, variable practice, and mechanisms to promote use of the paretic limb, can enhance clinical benefits. Studies in patients in the subacute and chronic phases of stroke were presented, showing that VR therapy combined with other therapies can bring about significant improvements in motor function, manual skill and other measures related to the performance of upper limb activities.

Post Stroke Depression: Relationship with Upper Limb Recovery, Activity and Participation

The feasibility of the adapted H-GRASP program for perceived and actual daily-life upper limb activity in the chronic phase post-stroke

(Purpose: Assessing feasibility and initial impact of the Home-Graded Repetitive Arm Supplementary Program combined with in-home accelerometer-based feedback (AH-GRASP) on perceived and actual daily-life upper limb (UL) activity in stroke survivors during the chronic phase with good UL motor function but low perceived daily-life activity. Material and methods: A 4-week intervention program (4 contact hours, 48 h self-practice) encompassing task-oriented training, behavioral techniques, phone-based support, monitoring, and weekly feedback sessions using wrist-worn accelerometery was implemented using a pre-post double baseline repeated measures design. Feasibility, clinical assessments, patient-reported outcomes, and accelerometer data were investigated. Results: Of the 34 individuals approached, nineteen were included (recruitment rate 56%). Two dropped out, one due to increased UL pain (retention rate 89%). Seven (41%) achieved the prescribed exercise target (120 min/day, six days/week). Positive patient experiences and improvements in UL capacity, self-efficacy, and contribution of the affected UL to overall activity (p < 0.05, small to large effect sizes) were observed. Additionally, seven participants (41%) surpassed the minimal clinically important difference in perceived UL activity.Conclusions: A home-based UL exercise program with accelerometer-based feedback holds promise for enhancing perceived and actual daily-life UL activity for our subgroup of chronic stroke survivors.

Effectiveness of Task-Specific Training combined with Strength Training on Upper Limb Recovery, Activities and Participation after Stroke: A Systematic Literature Review

Strength training in stroke focuses more on improving the impairment of muscle weakness after stroke. Task specific training along with strength training may improve upper limb impairment, functional outcome and participation after stroke. A systematic review was conducted to analyse the available evidence on task specific training combined with strength training on upper limb performance post stroke. Databases like The Cochrane Central Register of Trials (CENTRAL), PubMed, PEDro, Clinical Trial Registry of India and OTseeker were searched in order to find the required studies. Stroke, task-specific training, functional strength training, task-oriented strength training, task-specific strength training, upper limb performance, activities, and participation were the key search terms. Studies published in English language up to October 2023 were taken into consideration. For the purpose of the review, studies that examined the efficacy of combined strength training and task specific training on upper limb recovery, activity and participation post stroke were taken into account. The studies of other combinations with task specific training were excluded. Outcome measures measuring upper limb motor recovery, functional performance, activities and participation post stroke were considered in the review. Five studies were selected for the current systematic review out of the 384 studies screened. Task specific training combined with strength training functional strength training were reviewed in the selected studies. The review conclude that a combined therapeutic strategy using task specific training and strength training addressing improvement of upper limb recovery can be more effective in comparison to the standard therapy.
