Effectiveness of Immersive Virtual Reality-Based Hand Rehabilitation Games for Improving Hand Motor Functions in Subacute Stroke Patients

Stroke rehabilitation faces challenges in attaining enduring improvements in hand motor function and is frequently constrained by interventional limitations. This research aims to present an innovative approach to the integration of cognitive engagement within visual feedback incorporated into fully immersive virtual reality (VR) based games to achieve enduring improvements. These innovative aspects of interaction provide more functional advantages beyond motivation to efficiently execute repeatedly hand motor tasks. The effectiveness of virtual reality games incorporated with innovative aspects has been investigated for improvements in hand motor functions. A randomized controlled trial was conducted, a total of (n=56) subacute stroke patients were assessed for eligibility and (n=52) patients fulfilled the inclusion criteria. (n=26) patients were assigned to the experimental group and (n=26) patients were assigned to the control group. VR intervention involves four VR based games, developed based on hand movements including flexion/extension, close/open, supination/pronation and pinch. All patients got therapy of 24 sessions, lasting 4 days/week for a total of 6 weeks. Five clinical outcome measures were Fugl- Meyer Assessment-Upper Extremity, Action Research Arm Test, Box and Block Test, Modified Barthel Index, and Stroke-Specific Quality of Life were assessed to evaluate patients' performance. Results revealed that after therapy there was significant improvement between the groups (p<0.05) and within groups (p<0.05) in all assessment weeks in all clinical outcome measures however, improvement was observed significantly greater in the experimental group due to fully immersive VR-based games. Results indicated that cognitive engagement within visual feedback incorporated in VR-based hand games effectively improved hand motor functions.

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.

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.

Usability of a wearable device for home-based upper limb telerehabilitation in persons with stroke: A mixed-methods study

Background

The use of wearable technology offers a promising home-based self-directed option for upper limb training. Although product usability is a crucial aspect of users' acceptance of a wearable device, usability studies in wearable devices are rare, with most studies focusing primarily on clinical validity.

Objective

This study aimed to explore the usability of a wristwatch device called "Smart reminder" for home-based upper limb telerehabilitation for persons with stroke.

Methods

Eleven stroke participants used the proposed wristwatch for at least two weeks and underwent a home-based telerehabilitation program. A mixed-methods design was used to explore the usability of the wristwatch. Quantitative data were collected through the System Usability Scale (SUS) questionnaire, and the participants' rate of therapy compliance (gathered from the device) was reported descriptively. In addition, qualitative data were collected through semi-structured interviews with the participants and were analyzed using thematic analysis.

Results

The results demonstrated that the usability of the proposed wristwatch and telerehabilitation system was rated highly by the participants, with a high SUS mean score of 84.3 (12.3) and high therapy compliance rate (mean  =  91%). Qualitatively, all participants reported positive experiences with the wristwatch and indicated keenness to use it again. Participants reported physical improvements and felt motivated to exercise after using the wristwatch. They found the device easy and convenient and appreciated the remote monitoring function. Meanwhile, they highlighted critical considerations for the design of the device and program, including technical support, a wearable design of the device, graded exercise content according to ability, and flexibility in exercise schedules. Finally, they suggested that an interim review with the therapist on their progress might help them continue using the wristwatch.

Conclusions

This study's results supported the proposed wearable device's usability and showed strong acceptance by the participants for using it as a home-based upper limb telerehabilitation intervention.

Combined Transcutaneous Electrical Spinal Cord Stimulation and Task-Specific Rehabilitation Improves Trunk and Sitting Functions in People with Chronic Tetraplegia

The aim of this study was to examine the effects of transcutaneous electrical spinal cord stimulation (TSCS) and conventional task-specific rehabilitation (TSR) on trunk control and sitting stability in people with chronic tetraplegia secondary to a spinal cord injury (SCI). Five individuals with complete cervical (C4-C7) cord injury participated in 24-week therapy that combined TSCS and TSR in the first 12 weeks, followed by TSR alone for another 12 weeks. The TSCS was delivered simultaneously at T11 and L1 spinal levels, at a frequency ranging from 20-30 Hz with 0.1-1.0 ms. pulse width biphasically. Although the neurological prognosis did not manifest after either treatment, the results show that there were significant increases in forward reach distance (10.3 ± 4.5 cm), right lateral reach distance (3.7 ± 1.8 cm), and left lateral reach distance (3.0 ± 0.9 cm) after the combinational treatment (TSCS+TSR). The stimulation also significantly improved the participants' trunk control and function in sitting. Additionally, the trunk range of motion and the electromyographic response of the trunk muscles were significantly elevated after TSCS+TSR. The TSCS+TSR intervention improved independent trunk control with significantly increased static and dynamic sitting balance, which were maintained throughout the TSR period and the follow-up period, indicating long-term sustainable recovery.

Efficacy and feasibility of SENSory relearning of the UPPer limb (SENSUPP) in people with chronic stroke: A pilot randomized controlled trial

BACKGROUND

Sensorimotor impairments of the upper limb (UL) are common after stroke, but there is a lack of evidence-based interventions to improve functioning of UL.

OBJECTIVE

To evaluate (1) the efficacy of sensory relearning and task-specific training compared to task-specific training only, and (2) the feasibility of the training in chronic stroke.

DESIGN

A pilot randomized controlled trial.

SETTING

University hospital outpatient clinic.

PARTICIPANTS

Twenty-seven participants (median age; 62 years, 20 men) were randomized to an intervention group (IG; n = 15) or to a control group (CG; n = 12).

INTERVENTION

Both groups received training twice weekly in 2.5-hour sessions for 5 weeks. The training in the IG consisted of sensory relearning, task-specific training, and home training. The training in the CG consisted of task-specific training.

MAIN OUTCOME MEASURES

Primary outcome was sensory function (touch thresholds, touch discrimination, light touch, and proprioception). Secondary outcomes were dexterity, ability to use the hand in daily activities, and perceived participation. A blinded assessor conducted the assessments at baseline (T1), post intervention (T2), and at 3-month follow-up (T3). Nonparametric analyses and effect-size calculations (r) were performed. Feasibility was evaluated by a questionnaire.

RESULTS

After the training, only touch thresholds improved significantly from T1 to T2 (p = .007, r = 0.61) in the IG compared to the CG. Within the IG, significant improvements were found from T1 to T2 regarding use of the hand in daily activities (p = .001, r = 0.96) and movement quality (p = .004, r = 0.85) and from T1 to T3 regarding satisfaction with performance in meaningful activities (p = .004, r = 0.94). The CG significantly improved the performance of using the hand in meaningful activities from T1 to T2 (p = .017, r = 0.86). The training was well tolerated by the participants and performed without any adverse events.

CONCLUSIONS

Combined sensory relearning and task-specific training may be a promising and feasible intervention to improve UL sensorimotor function after stroke.

Effectiveness of home-based upper limb rehabilitation in stroke survivors: A systematic review and meta-analysis

Background

Home-based training is an alternative option to provide intensive rehabilitation without costly supervised therapy. Though several studies support the effectiveness of home-based rehabilitation in improving hemiparetic upper limb function in stroke survivors, a collective evaluation of the evidence remains scarce.

Objectives

This study aims to determine the effects of home-based upper limb rehabilitation for hemiparetic upper limb recovery in stroke survivors.

Methods

The databases of the Cochrane Library, MEDLINE, CINAHL, and Web of Science were systematically searched from January 2000 to September 2020. Only randomized, controlled, and cross-over trials that evaluated the effects of home-based upper limb interventions were selected. The Pedro scale was used to assess the methodological quality of the studies. A meta-analysis of the upper limb function outcomes was performed by calculating the mean difference/standardized mean difference using a fixed/random effect model.

Results

An initial search yielded 1,049 articles. Twenty-six articles were included in the review. The pooled evidence of the meta-analysis showed that home-based upper limb intervention was more effective in improving upper limb function [SMD: 0.28, 95% CI (0.12, 0.44), I² = 0%, p < 0.001, fixed effect model] than conventional therapy. When comparing two types of home-based interventions, subgroup analysis revealed that home-based technology treatment—electrical stimulation—provided more significant improvement in upper limb function than treatment without the use of technology (SMD: 0.64, 95% CI (0.21, 1.07), I² = 0%, p = 0.003, random effect model).

Conclusion

The beneficial effects of home-based upper limb interventions were superior to conventional therapy in improving function and perceived use of the hemiparetic upper limb in daily activities. Among the home-based interventions, home-based electrical stimulation seemed to provide the most optimal benefits.

Execution of natural manipulation in the air enhances the beta-rhythm intermuscular coherences of the human arm depending on muscle pairs

Natural manipulation tasks in air consist of two kinematic components: a grasping component, with activation of the hand muscles, and a lifting component, with activation of the proximal muscles. However, it remains unclear whether the synchronized motor commands to the hand/proximal arm muscles are divergently controlled during the task. Therefore, we examined how intermuscular coherence was modulated depending on the muscle combinations during grip and lift (G&L) tasks. Electromyograms (EMGs) were recorded from the biceps brachii (BB), triceps brachii (TB), flexor digitorum superficialis (FDS), and extensor digitorum communis (EDC) muscles. The participants were required to maintain G&L tasks involving a small cubical box with the thumb and index and middle fingers. Consequently, we found that the beta-rhythm coherence (15-35 Hz) in BB-TB, BB-FDS, and TB-EDC pairs during G&L was significantly larger than that during the isolated task with cocontraction of the two target muscles but not BB-EDC, TB-FDS, and FDS-EDC (task and muscle pair specificities). These increases in beta-rhythm coherence were also observed in intramuscular EMG recordings. Furthermore, the results from the execution of several mimic G&L tasks revealed that the separated task-related motor signals and combinations between the motor signals/sensations of the fingertips or object load had minor contributions to the increase in the coherence. These results suggest that during G&L the central nervous system regulates synchronous drive onto motoneurons depending on the muscle pairs and that the multiple combination effect of the sensations of touch/object load and motor signals in the task promotes the synchrony of these pairs.NEW & NOTEWORTHY Natural manipulation in air consists of two kinematic components: grasping, with activation of hand muscles, and lifting, with activation of proximal muscles. We show that during the maintenance of object manipulation in air the central nervous system regulates the synchronous drive onto human motoneuron pools depending on the hand/proximal muscle pairs and that the multiple combination effect of the sensations of touch/object load and motor signals in the task promotes the synchrony of these pairs.

SENSory re-learning of the UPPer limb (SENSUPP) after stroke: development and description of a novel intervention using the TIDieR checklist

Background

Sensorimotor impairments of upper limb (UL) are common after stroke, leading to difficulty to use the UL in daily life. Even though many have sensory impairments in the UL, specific sensory training is often lacking in stroke rehabilitation. Thus, the aim of this paper is to provide a detailed description of the novel intervention “SENSory re-learning of the UPPer limb after stroke (SENSUPP)” that we have developed to improve functioning in the UL in persons with mild to moderate impairments after stroke.

Methods

The SENSUPP protocol was designed using information from literature reviews, clinical experience and through consultation of experts in the field. The protocol integrates learning principles based on current neurobiological knowledge and includes repetitive intensive practice, difficulty graded exercises, attentive exploration of a stimulus with focus on the sensory component, and task-specific training in meaningful activities that includes feedback. For reporting the SENSUPP protocol, the Template for Intervention Description and Replication (TIDieR) checklist was used.

Results

The essential features of the SENSUPP intervention comprise four components: applying learning principles based on current neurobiological knowledge, sensory re-learning (exercises for touch discrimination, proprioception and tactile object recognition), task-specific training in meaningful activities, and home-training. The training is performed twice a week, in 2.5-h sessions for 5 weeks.

Conclusion

Since there is close interaction between the sensory and motor systems, the SENSUPP intervention may be a promising method to improve UL functioning after stroke. The TIDieR checklist has been very useful for reporting the procedure and development of the training.

Robot-assisted training compared with an enhanced upper limb therapy programme and with usual care for upper limb functional limitation after stroke: the RATULS three-group RCT

BACKGROUND

Loss of arm function is common after stroke. Robot-assisted training may improve arm outcomes.

OBJECTIVE

The objectives were to determine the clinical effectiveness and cost-effectiveness of robot-assisted training, compared with an enhanced upper limb therapy programme and with usual care.

DESIGN

This was a pragmatic, observer-blind, multicentre randomised controlled trial with embedded health economic and process evaluations.

SETTING

The trial was set in four NHS trial centres.

PARTICIPANTS

Patients with moderate or severe upper limb functional limitation, between 1 week and 5 years following first stroke, were recruited.

INTERVENTIONS

Robot-assisted training using the Massachusetts Institute of Technology-Manus robotic gym system (InMotion commercial version, Interactive Motion Technologies, Inc., Watertown, MA, USA), an enhanced upper limb therapy programme comprising repetitive functional task practice, and usual care.

MAIN OUTCOME MEASURES

The primary outcome was upper limb functional recovery 'success' (assessed using the Action Research Arm Test) at 3 months. Secondary outcomes at 3 and 6 months were the Action Research Arm Test results, upper limb impairment (measured using the Fugl-Meyer Assessment), activities of daily living (measured using the Barthel Activities of Daily Living Index), quality of life (measured using the Stroke Impact Scale), resource use costs and quality-adjusted life-years.

RESULTS

A total of 770 participants were randomised (robot-assisted training, n = 257; enhanced upper limb therapy, n = 259; usual care, n = 254). Upper limb functional recovery 'success' was achieved in the robot-assisted training [103/232 (44%)], enhanced upper limb therapy [118/234 (50%)] and usual care groups [85/203 (42%)]. These differences were not statistically significant; the adjusted odds ratios were as follows: robot-assisted training versus usual care, 1.2 (98.33% confidence interval 0.7 to 2.0); enhanced upper limb therapy versus usual care, 1.5 (98.33% confidence interval 0.9 to 2.5); and robot-assisted training versus enhanced upper limb therapy, 0.8 (98.33% confidence interval 0.5 to 1.3). The robot-assisted training group had less upper limb impairment (as measured by the Fugl-Meyer Assessment motor subscale) than the usual care group at 3 and 6 months. The enhanced upper limb therapy group had less upper limb impairment (as measured by the Fugl-Meyer Assessment motor subscale), better mobility (as measured by the Stroke Impact Scale mobility domain) and better performance in activities of daily living (as measured by the Stroke Impact Scale activities of daily living domain) than the usual care group, at 3 months. The robot-assisted training group performed less well in activities of daily living (as measured by the Stroke Impact Scale activities of daily living domain) than the enhanced upper limb therapy group at 3 months. No other differences were clinically important and statistically significant. Participants found the robot-assisted training and the enhanced upper limb therapy group programmes acceptable. Neither intervention, as provided in this trial, was cost-effective at current National Institute for Health and Care Excellence willingness-to-pay thresholds for a quality-adjusted life-year.

CONCLUSIONS

Robot-assisted training did not improve upper limb function compared with usual care. Although robot-assisted training improved upper limb impairment, this did not translate into improvements in other outcomes. Enhanced upper limb therapy resulted in potentially important improvements on upper limb impairment, in performance of activities of daily living, and in mobility. Neither intervention was cost-effective.

FUTURE WORK

Further research is needed to find ways to translate the improvements in upper limb impairment seen with robot-assisted training into improvements in upper limb function and activities of daily living. Innovations to make rehabilitation programmes more cost-effective are required.

LIMITATIONS

Pragmatic inclusion criteria led to the recruitment of some participants with little prospect of recovery. The attrition rate was higher in the usual care group than in the robot-assisted training or enhanced upper limb therapy groups, and differential attrition is a potential source of bias. Obtaining accurate information about the usual care that participants were receiving was a challenge.

Evaluation of the enhanced upper limb therapy programme within the Robot-Assisted Training for the Upper Limb after Stroke trial: descriptive analysis of intervention fidelity, goal selection and goal achievement

Objective:

To report the fidelity of the enhanced upper limb therapy programme within the Robot-Assisted Training for the Upper Limb after stroke (RATULS) randomized controlled trial, the types of goals selected and the proportion of goals achieved.

Design:

Descriptive analysis of data on fidelity, goal selection and achievement from an intervention group within a randomized controlled trial.

Setting:

Out-patient stroke rehabilitation within four UK NHS centres.

Subjects:

259 participants with moderate-severe upper limb activity limitation (Action Research Arm Test 0–39) between one week and five years post first stroke.

Intervention:

The enhanced upper limb therapy programme aimed to provide 36 one-hour sessions, including 45 minutes of face-to-face therapy focusing on personal goals, over 12 weeks.

Results:

7877/9324 (84%) sessions were attended; a median of 34 [IQR 29–36] per participant. A median of 127 [IQR 70–190] repetitions were achieved per participant per session attended. Based upon the Canadian Occupational Performance Measure, goal categories were: self-care 1449/2664 (54%); productivity 374/2664 (14%); leisure 180/2664 (7%) and ‘other’ 661/2664 (25%). For the 2051/2664 goals for which data were available, 1287 (51%) were achieved, ranging between 27% by participants more than 12 months post stroke with baseline Action Research Arm Test scores 0–7, and 88% by those less than three months after stroke with scores 8–19.

Conclusions:

Intervention fidelity was high. Goals relating to self-care were most commonly selected. The proportion of goals achieved varied, depending on time post stroke and baseline arm activity limitation.

Guidance for reporting intervention development studies in health research (GUIDED): an evidence-based consensus study

OBJECTIVE

To improve the quality and consistency of intervention development reporting in health research.

DESIGN

This was a consensus exercise consisting of two simultaneous and identical three-round e-Delphi studies (one with experts in intervention development and one with wider stakeholders including funders, journal editors and public involvement members), followed by a consensus workshop. Delphi items were systematically derived from two preceding systematic reviews and a qualitative interview study.

PARTICIPANTS

Intervention developers (n=26) and wider stakeholders (n=18) from the UK, North America and Europe participated in separate e-Delphi studies. Intervention developers (n=13) and wider stakeholders (n=13) participated in a 1-day consensus workshop.

RESULTS

e-Delphi participants achieved consensus on 15 reporting items. Following feedback from the consensus meeting, the final inclusion and wording of 14 items with description and explanations for each item were agreed. Items focus on context, purpose, target population, approaches, evidence, theory, guiding principles, stakeholder contribution, changes in content or format during the development process, required changes for subgroups, continuing uncertainties, and open access publication. They form the GUIDED (GUIDance for the rEporting of intervention Development) checklist, which contains a description and explanation of each item, alongside examples of good reporting.

CONCLUSIONS

Consensus-based reporting guidance for intervention development in health research is now available for publishers and researchers to use. GUIDED has the potential to lead to greater transparency, and enhance quality and improve learning about intervention development research and practice.

Home program practices for supporting and measuring adherence in post-stroke rehabilitation: a scoping review

BACKGROUND

After stroke, individuals face a variety of impairments that impact function. Increasingly, rehabilitation for these impairments has moved into the community and home settings through the use of home programs. However, adherence to these programs is often low, limiting effectiveness.

OBJECTIVE

This scoping review investigated home program implementation and measurement of adherence with persons post-stroke to identify commonly reported practices and determine areas for further research.

METHODS

The electronic databases of PubMed, CINAHL, Scopus, Cochrane Database of Systematic Reviews, and PEDro were searched. Studies focused on post-stroke rehabilitation with an independent home program were selected. Qualitative studies, commentaries, and single-case studies were excluded. Title and abstract screenings were completed by two reviewers with a third for tie-breaking. The full-text review was completed by two reviewers using consensus to resolve any differences. Of the 1,197 articles initially found only 6% (n = 70) met criteria for data extraction. Elements for data extraction included: type of study, area of intervention, description of home program, presence of strategies to support adherence, methods to measure adherence and reported adherence.

RESULTS

Most commonly reported strategies to support home practice were the use of technology, personalization, and written directions. Only 20 studies reported achieving adherence at or greater than 75% and 18 studies did not report adherence outcomes.

CONCLUSIONS

Future investigations that directly compare and identify the most effective strategies to support adherence to home programs for this population are warranted. The implementation of guidelines for reporting adherence to home programs is recommended.

Aerobic exercise and consecutive task-specific training (AExaCTT) for upper limb recovery after stroke: A randomized controlled pilot study

OBJECTIVE

This study examined the feasibility of a parallel-group assessor-blinded randomized controlled trial investigating whether task-specific training preceded by aerobic exercise (AEX + TST) improves upper limb function more than task-specific training (TST) alone.

METHODS

People with upper limb motor dysfunction after stroke were allocated to TST or AEX + TST. Both groups were prescribed 60 hr of TST over 10 weeks (3 × 1-hr sessions with a therapist per week and 3 × 1 hr of home-based self-practice per week). The AEX + TST group performed 30 minutes of aerobic exercise immediately prior to the 1 hr of TST with the therapist. Recruitment, adherence, retention, participant acceptability, and adverse events were recorded. Clinical measures were performed prerandomization at baseline, on completion of the intervention, and at 1- and 6-month follow-up.

RESULTS

Fifty-nine persons after stroke were screened, 42 met the eligibility criteria, and 20 (11 male; mean [SD] age: 55.4 [16.0] years; time since stroke: 71.7 [91.2] months) were recruited over 17 months. The mean Wolf Motor Function Test Functional Ability Score at baseline was 27.4 (max = 75) and the mean Action Research Arm Test score was 11.2 (max = 57). Nine were randomized to AEX + TST and 11 to TST. There were no adverse events, but there was one drop out. Retention at 1- and 6-month follow-up was 80% and 85%, respectively. Attendance was 93% (6) for the AEX + TST group, and 89% (9) for the TST group. AEX + TST was perceived as acceptable (100%) and beneficial (87.5%). Exertional fatigue (visual analogue scale) prior to TST was worse in the AEX + TST group (3.5 [0.7] out of 10) than the TST group (1.7 [1.4] out of 10). The TST group performed 31% more repetitions per session than the AEX + TST group.

CONCLUSION

A subsequent Phase III study is feasible, but modifications to eligibility criteria, outcome measures, and intervention delivery are recommended.

Systematic scoping review of frameworks used to develop rehabilitation interventions for older adults

OBJECTIVES

Rehabilitation interventions for older adults are complex as they involve a number of interacting components, have multiple outcomes of interest and are influenced by a number of contextual factors. The importance of rigorous intervention development prior to formal evaluation has been acknowledged and a number of frameworks have been developed. This review explored which frameworks have been used to guide the development of rehabilitation interventions for older adults.

DESIGN

Systematic scoping review.

SETTING

Studies were not limited for inclusion based on setting.

PARTICIPANTS

Studies were included that featured older adults (>65 years of age).

INTERVENTIONS

Studies were included that reported the development of a rehabilitation intervention.

PRIMARY AND SECONDARY OUTCOME MEASURES

Data were extracted on study population, setting, type of intervention developed and frameworks used. The primary outcome of interest was the type of intervention development framework.

RESULTS

Thirty-five studies were included. There was a range of underlying medical conditions including mild cognitive impairment and dementia (n=5), cardiac (n=4), stroke (n=3), falls (n=3), hip fracture (n=2), diabetes (n=2), breast cancer (n=1), Parkinson's disease (n=1), depression (n=1), chronic health problems (n=1), osteoarthritis (n=1), leg ulcer (n=1), neck pain (n=1) and foot problems (n=1). The intervention types being developed included multicomponent, support based, cognitive, physical activities, nursing led, falls prevention and occupational therapy led. Twelve studies (34%) did not report using a framework. Five frameworks were reported with the Medical Research Council (MRC) framework for developing and evaluating complex interventions being the most frequently cited (77%, n=17).

CONCLUSION

At present, the MRC framework is the most popular for developing rehabilitation interventions for older adults. Many studies do not report using a framework. Further, specific guidance to assist this complex field of rehabilitation research is required.

A professional development program increased the intensity of practice undertaken in an inpatient, upper limb rehabilitation class: A pre-post study

BACKGROUND/AIM

Increasing the intensity of practice is associated with improved upper limb outcomes, yet observed intensity levels during rehabilitation are low. The purpose of this study was to investigate: whether a professional development program would increase the intensity of practice undertaken in an inpatient, upper limb rehabilitation class; and whether any increase would be maintained six months after the cessation of the program.

METHOD

A pre-post study was conducted within an existing inpatient, upper limb rehabilitation class in a metropolitan hospital. Staff received a professional development program which included: a two day theoretical, practical and clinical training workshop covering evidence-based practice for upper limb rehabilitation after stroke; and three 1-hour meetings to revise evidence-based practice and discuss implementation of strategies. Intensity of practice, as measured by the proportion of practice time per class (%) and the number of repetitions per practice time (repetitions/min) observed during the 60-minute classes during one week, was recorded at baseline, end of program (12 months) and six months later (18 months).

RESULTS

Twenty-two (100%) staff attended at least one professional development program session; outcomes were measured across n = 15 classes (n = 30 patients). Between baseline and 12 months, the mean proportion of practice time per class increased by 52% (95% confidence interval (CI) 33-70; P < 0.001) and the mean number of repetitions per practice time increased by 5.1 repetitions/min (95% CI 1.7-8.4; P < 0.01). Between baseline and 18 months, the mean proportion of practice time per class increased by 53% (95% CI 36-69; P < 0.001) and the mean number of repetitions per practice time increased by 3.9 repetitions/min (95% CI 1.9-5.9; P < 0.001).

CONCLUSION

Providing professional development was associated with increased intensity of practice in an inpatient, upper limb rehabilitation class. The increase was maintained six months later.

COMbined Physical and somatoSEnsory training after stroke: Development and description of a novel intervention to improve upper limb function

BACKGROUND AND PURPOSE

After stroke, reach-to-grasp goal-directed movements are disrupted as a result of both residual motor and somatosensory impairments. This report describes the rationale and development of a new upper limb stroke rehabilitation intervention known as COMPoSE: "COMbined Physical and somatoSEnsory training," designed to improve somatosensory and motor deficits in the upper limb after stroke. A standardized training matrix has been developed to facilitate intervention delivery.

METHODS

The COMPoSE intervention was developed through the following stages: (a) Definition and operationalization of somatosensory and motor variables used in training sensation and movement after stroke; (b) development of methods to give feedback to enhance skill acquisition; and (c) Combination of somatosensory and motor variables, and feedback, into a standardized training matrix. The reporting of the COMPoSE intervention adheres to the recommendations of the Template for Intervention Description and Replication checklist to facilitate replication of the intervention in the future.

RESULTS

The essential features of COMPoSE include combined somatosensory-motor training variables (grasp pressure, distance, object size, crushability, surface texture, and friction), feedback, and calibration using a haptic device providing measures of grasp pressure, use of anticipation trials, and high-dose repetitive task practice. Ten treatment sessions are delivered over 3 weeks, using a standardized matrix for treatment delivery.

CONCLUSION

COMPoSE is a new intervention that combines somatosensory and movement training, delivered synchronously, within the same intervention, and within the same task.

The Sano study: justification and detailed description of a multidisciplinary biopsychosocial rehabilitation programme in patients with chronic low back pain

Objective:

To justify and describe an integrated rehabilitation programme for patients with chronic low back pain prior to evaluation in a randomized controlled trial.

Method:

The Template for Intervention Description and Replication (TIDieR) checklist was used as a structural framework for the description of the integrated rehabilitation programme. As a part of the description, the Medical Research Council guidance, ‘Developing and evaluating complex interventions’, was used as a framework to justify the integrated rehabilitation programme.

Intervention description:

The integrated rehabilitation programme adopts a participatory biopsychosocial approach integrating inpatient activities supported by a multidisciplinary team and learning located within the patient’s own environment. The integrated rehabilitation programme comprises 3 weeks of inpatient stay and 11 weeks of home-based activities. The inpatient part of the programme consists of 38 clinical activities, some of them delivered more than once. The 38 clinical activities were described in an activity sheet developed for this purpose, combining five items from the TIDieR.

Conclusion:

An integrated rehabilitation programme for patients with chronic low back pain has been justified and described. The intervention description is currently being used for successful structuring and standardization of the content and delivery of the integrated rehabilitation programme in a randomized controlled trial.

AExaCTT - Aerobic Exercise and Consecutive Task-specific Training for the upper limb after stroke: Protocol for a randomised controlled pilot study

Motor function may be enhanced if aerobic exercise is paired with motor training. One potential mechanism is that aerobic exercise increases levels of brain-derived neurotrophic factor (BDNF), which is important in neuroplasticity and involved in motor learning and motor memory consolidation. This study will examine the feasibility of a parallel-group assessor-blinded randomised controlled trial investigating whether task-specific training preceded by aerobic exercise improves upper limb function more than task-specific training alone, and determine the effect size of changes in primary outcome measures. People with upper limb motor dysfunction after stroke will be allocated to either task-specific training or aerobic exercise and consecutive task-specific training. Both groups will perform 60 hours of task-specific training over 10 weeks, comprised of 3 × 1 hour sessions per week with a therapist and 3 × 1 hours of home-based self-practice per week. The combined intervention group will also perform 30 minutes of aerobic exercise (70-85%HRmax) immediately prior to the 1 hour of task-specific training with the therapist. Recruitment, adherence, retention, participant acceptability, and adverse events will be recorded. Clinical outcome measures will be performed pre-randomisation at baseline, at completion of the training program, and at 1 and 6 months follow-up. Primary clinical outcome measures will be the Action Research Arm Test (ARAT) and the Wolf Motor Function Test (WMFT). If aerobic exercise prior to task-specific training is acceptable, and a future phase 3 randomised controlled trial seems feasible, it should be pursued to determine the efficacy of this combined intervention for people after stroke.

Home-based Reach-to-Grasp training for people after stroke is feasible: a pilot randomised controlled trial

Objective:

To determine feasibility of a randomised controlled trial (RCT) of home-based Reach-to-Grasp training after stroke.

Design:

single-blind parallel group RCT.

Participants:

Residual arm deficit less than 12 months post-stroke.

Interventions:

Reach-to-Grasp training in 14 one-hour therapist’s visits over 6 weeks, plus one hour self-practice per day (total 56 hours). Control: Usual care.

Main Measures:

Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), pre-randomisation, 7, 12, 24 weeks post-randomisation.

Results:

Forty-seven participants (Reach-to-Grasp=24, usual care=23) were randomised over 17 months. Reach-to-Grasp participants received a median (IQR) 14 (13,14) visits, and performed 157 (96,211) repetitions per visit; plus 30 minutes (22,45) self-practice per day. Usual care participants received 10.5 (5,14) therapist visits, comprising 38.6 (30,45) minutes of arm therapy with 16 (6,24) repetitions of functional tasks per visit. Median ARAT scores in the reach-to-grasp group were 8.5 (3.0,24.0) at baseline and 14.5 (3.5,26.0) at 24 weeks compared to median of 4 at both time points (IQR: baseline (3.0,14.0), 24 weeks (3.0,30.0)) in the usual-care group. Median WMFT tasks completed at baseline and 24 weeks were 6 (3.0,11.5) and 8.5 (4.5,13.5) respectively in the reach-to-grasp group and 4 (3.0,10.0), 6 (3.0,14.0) in the usual care group. Incidence of arm pain was similar between groups. The study was stopped before 11 patients reached the 24 weeks assessment.

Conclusions:

An RCT of home-based Reach-to-Grasp training after stroke is feasible and safe. With ARAT being our preferred measure it is estimated that 240 participants will be needed for a future two armed trial.
