Intensity-dependent clinical effects of an individualized technology-supported task-oriented upper limb training program in Multiple Sclerosis: A pilot randomized controlled trial

High-Intensity Functional Activities Specific Training (FAST) in Post-Stroke Rehabilitation: A Randomized Trial on Motor Recovery and Quality of Life Improvements

BACKGROUND

Stroke often leads to long-term disability, impacting motor function, mobility, and quality of life. However, the effectiveness of different intensities of functional training in improving these outcomes in stroke rehabilitation is not well established.

PURPOSE

This study aimed to determine the effects of different intensities of functional activities specific training on upper extremity function, mobility, fall risk, and quality of life in stroke patients.

METHODS

This randomized controlled trial was conducted in a rehabilitation setting (PRH Islamabad) with age 40-60 years and 3 months post-stroke. Participants (N = 99) were randomly (simple) assigned to conventional therapy, moderate-intensity, or high-intensity training with 33 in each group. Eligibility criteria included a Montreal Cognitive Assessment score of 18-25, Fugl-Meyer Assessment score of 50-70 and a Modified Rankin Scale score of 3 and 4, suggesting moderate motor impairment and moderate to severe disability, respectively. Participants with severe spasticity, inability to follow two-step commands, concurrent stroke treatments, other neurological conditions, and a history of falls were excluded. The 12-week training program utilized the FAST-Table, and outcomes including Fugl-Meyer Assessment for upper extremity, Berg Balance Scale, and Stroke-Specific Quality of Life Urdu scale-were assessed at baseline, 4, 8, and 12 weeks.

RESULTS

The mean age of participants were 65.4 ± 7.2 years, gender (52% male, 48% female, ischemic 70%, and hemorrhagic 30%). The high-intensity group showed significant improvements in Fugl-Meyer Assessment-Upper Extremity scores at weeks 8 and 12 (p < 0.05), Timed Up and Go test (p < 0.05), Berg Balance Scale scores (p < 0.05), and Stroke-Specific Quality of Life Urdu scale (p < 0.05). Moderate-intensity and conventional groups also showed improvements individually.

DISCUSSION

High-intensity functional training leads to greater improvements in physical performance and quality of life in stroke survivors compared with moderate-intensity functional training and conventional therapies.

Task-oriented for upper limb rehabilitation in people with multiple sclerosis: A systematic review of randomized trials

OBJECTIVES

To assess the effects of task-oriented (TO) training on upper limb dysfunction (ULD) in individuals with multiple sclerosis (PwMS).

METHODS

PubMed, Scopus, EMBASE, REHABDATA, Web of Science, and PEDro were searched from inception to May 2024. Only randomized that used TO training for upper limb functions of PwMS were included. One author screened records, extracted data, and evaluated the quality of the selected studies using the Cochrane Collaboration tool, and the results were subsequently checked by another researcher.

RESULTS

Five randomized trials met the eligibility criteria. A total of 116 PwMS, 62 % of whom were women, were included in this study. Four studies revealed "high" quality, and one exposed a "moderate" quality. The studies incorporated in the analysis indicated that TO training did not yield a superior effect on upper limb recovery in PwMS compared to other conventional treatments.

CONCLUSIONS

TO training is a safe intervention in PwMS. The evidence for the impact of TO training on upper extremity function in PwMS was limited. Additional studies with long-term follow-ups are required to understand the effects of TO on ULD in PwMS.

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.

Telerehabilitation versus virtual reality supported task-oriented circuit therapy on upper limbs and trunk functions in patients with multiple sclerosis: A randomized controlled study

INTRODUCTION

The purpose of this study was to investigate the effects of two different technology-supported rehabilitation approaches which are mobile application based telerehabilitation (TR) and virtual reality supported task oriented circuit therapy groups (V-TOCT) on the upper limb (UL), trunk function, and functional activity kinematics in patients with Multiple Sclerosis (PwMS).

METHODS

Thirty-four patients with PwMS were included in this study. The participants were evaluated at baseline and after eight weeks of treatment by an experienced physiotherapist using the Trunk Impairment Scale (TIS), kinetic function sub-parameter of the International Cooperative Ataxia Rating Scale (K-ICARS), ABILHAND, Minnesota Manual Dexterity tests (MMDT), and trunk and UL kinematics using inertial sensors. The participants were randomized into the TR and V-TOCT groups with a 1:1 allocation ratio. All participants received interventions for 1 hour per session, 3 sessions per week, for 8 weeks.

RESULTS

Trunk impairment, ataxia severity, UL, and hand function showed statistically significant improvement in both groups. The functional range of motion (FRoM) of shoulder and wrist increased transversal plane and the FRoM of shoulder increased on sagittal plane in V-TOCT. Log Dimensionless Jerk (LDJ) decreased on transversal plane in V-TOCT group. The FRoM of the trunk joints increased on the coronal plane and the FRoM of the trunk joints increased on the transversal plane in TR. Dynamic balance of the trunk and K-ICARS improved better in V-TOCT than in TR (p < 0,05).

CONCLUSIONS

V-TOCT and TR improved UL function, TIS, and ataxia severity in PwMS. The V-TOCT was more effective than the TR in terms of dynamic trunk control and kinetic function. The clinical results were confirmed using the kinematic metrics of motor control.

Efficacy of a technology-based client-centred training system in neurological rehabilitation: a randomised controlled trial

Background

A client-centred task-oriented approach has advantages towards motivation and adherence to therapy in neurorehabilitation, but it is costly to integrate in practice. An intelligent Activity-based Client-centred Training (i-ACT), a low-cost Kinect-based system, was developed which integrates a client-centred and task-oriented approach. The objectives were (1) to investigate the effect of additional i-ACT training on functioning. And (2) to assess whether training with i-ACT resulted in more goal oriented training.

Methods

A single-blind randomised controlled trial was performed in 4 Belgian rehabilitation centres with persons with central nervous system deficits. Participants were randomly allocated through an independent website-based code generator using blocked randomisation (n = 4) to an intervention or control group. The intervention group received conventional care and additional training with i-ACT for 3 × 45 min/week during 6 weeks. The control group received solely conventional care. Functional ability and performance, quality of life (QoL), fatigue, trunk movement, and shoulder active range of motion (AROM) were assessed at baseline, after 3 weeks and 6 weeks of training, and 6 weeks after cessation of training. Data were analysed using non-parametric within and between group analysis.

Results

47 persons were randomised and 45 analysed. Both intervention (n = 25) and control (n = 22) group improved over time on functional ability and performance as measured by the Wolf Motor Function Test, Manual Ability Measure-36, and Canadian Occupational Performance Measure, but no major differences were found between the groups on these primary outcome measures. Regarding QoL, fatigue, trunk movement, and shoulder AROM, no significant between group differences were found. High adherence for i-ACT training was found (i.e. 97.92%) and no adverse events, linked to i-ACT, were reported. In the intervention group the amount of trained personal goals (88%) was much higher than in the control group (46%).

Conclusions

Although additional use of i-ACT did not have a statistically significant added value regarding functional outcome over conventional therapy, additional i-ACT training provides more individualised client-centred therapy, and adherence towards i-ACT training is high. A higher intensity of i-ACT training may increase therapy effects, and should be investigated in future research.

Personalized prediction of rehabilitation outcomes in multiple sclerosis: a proof-of-concept using clinical data, digital health metrics, and machine learning

Predicting upper limb neurorehabilitation outcomes in persons with multiple sclerosis (pwMS) is essential to optimize therapy allocation. Previous research identified population-level predictors through linear models and clinical data. This work explores the feasibility of predicting individual neurorehabilitation outcomes using machine learning, clinical data, and digital health metrics. Machine learning models were trained on clinical data and digital health metrics recorded pre-intervention in 11 pwMS. The dependent variables indicated whether pwMS considerably improved across the intervention, as defined by the Action Research Arm Test (ARAT), Box and Block Test (BBT), or Nine Hole Peg Test (NHPT). Improvements in ARAT or BBT could be accurately predicted (88% and 83% accuracy) using only patient master data. Improvements in NHPT could be predicted with moderate accuracy (73%) and required knowledge about sensorimotor impairments. Assessing these with digital health metrics over clinical scales increased accuracy by 10%. Non-linear models improved accuracy for the BBT (+ 9%), but not for the ARAT (-1%) and NHPT (-2%). This work demonstrates the feasibility of predicting upper limb neurorehabilitation outcomes in pwMS, which justifies the development of more representative prediction models in the future. Digital health metrics improved the prediction of changes in hand control, thereby underlining their advanced sensitivity.

Graphical Abstract

Occupational Therapy Interventions in Adults with Multiple Sclerosis or Amyotrophic Lateral Sclerosis: A Scoping Review

This scoping review aims to describe occupational therapy interventions carried out with multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS) patients in occupational therapy. A peer review of the literature was conducted in different databases: Pubmed, Scopus, Web of Science and Embase, and in some occupational therapy journals. A search of the literature published was carried out before December 2019. The inclusion criteria were as follows: (1) articles evaluating the intervention of occupational therapy in MS or ALS including experimental, randomized, nonrandomized and exploratory studies; (2) written in English or Spanish; (3) adult population (over 18 years old). The initial search identified 836 articles of which we included 32 divided into four areas of intervention: fatigue-targeted interventions, cognitive interventions, physical interventions and others. Only 16 studies were carried out exclusively by occupational therapists. Most occupational therapy interventions are aimed at fatigue and physical rehabilitation. The majority of the studies in our review included MS patients, with little representation from the ALS population. These interventions have shown an improvement in perceived fatigue, manual dexterity, falls prevention and improvement in cognitive aspects such as memory, communication, depression and quality of life in the MS and ALS populations.

A data-driven framework for selecting and validating digital health metrics: use-case in neurological sensorimotor impairments

Digital health metrics promise to advance the understanding of impaired body functions, for example in neurological disorders. However, their clinical integration is challenged by an insufficient validation of the many existing and often abstract metrics. Here, we propose a data-driven framework to select and validate a clinically relevant core set of digital health metrics extracted from a technology-aided assessment. As an exemplary use-case, the framework is applied to the Virtual Peg Insertion Test (VPIT), a technology-aided assessment of upper limb sensorimotor impairments. The framework builds on a use-case-specific pathophysiological motivation of metrics, models demographic confounds, and evaluates the most important clinimetric properties (discriminant validity, structural validity, reliability, measurement error, learning effects). Applied to 77 metrics of the VPIT collected from 120 neurologically intact and 89 affected individuals, the framework allowed selecting 10 clinically relevant core metrics. These assessed the severity of multiple sensorimotor impairments in a valid, reliable, and informative manner. These metrics provided added clinical value by detecting impairments in neurological subjects that did not show any deficits according to conventional scales, and by covering sensorimotor impairments of the arm and hand with a single assessment. The proposed framework provides a transparent, step-by-step selection procedure based on clinically relevant evidence. This creates an interesting alternative to established selection algorithms that optimize mathematical loss functions and are not always intuitive to retrace. This could help addressing the insufficient clinical integration of digital health metrics. For the VPIT, it allowed establishing validated core metrics, paving the way for their integration into neurorehabilitation trials.

Telecommunication and rehabilitation for patients with multiple sclerosis: access and willingness to use. A cross-sectional study

BACKGROUND

Telerehabilitation is a promising approach for patients with multiple sclerosis (MS), but uncertainties regarding patients' access and preferences remain.

AIM

To investigate the access to telecommunication technologies and rehabilitation services of patients with MS, and their willingness to use these technologies for rehabilitation.

DESIGN

Cross-sectional survey.

SETTING

Outpatient neurological facility.

POPULATION

Patients with MS.

METHODS

Patients with MS attending consultations in the Neurology department were asked to fill in a paper questionnaire. This anonymous z was designed to gain information about needs and access to rehabilitation and telecommunication technologies, as well as interests and perspectives of telerehabilitation among these patients. Descriptive statistics, Chi-squared tests and logistic regressions were used to describe the sample and survey answers.

RESULTS

Two hundred patients completed the questionnaire. Mean age was 44.41(±12.52) years. Seventy-one percent were women, and 49% were unemployed. Ninety-one percent of the patients regularly used internet and 73% used apps. Most patients were interested in using telecommunication technologies to receive a program of physical exercises (62%), for information and personalized advice about physical activity and MS (69%), and to communicate with caregivers (75%). Patients with EDSS>4 were less interested than patients with EDSS≤4 in communicating with the caregivers via apps (33% vs. 52%,Δ19%[CI-36%;-2%],P=0.04) but expressed greater interest in receiving information and personal advice about physical activity and MS via the internet (70% vs. 51%,Δ19%[CI+2%;+36%],P=0.03). One third of the patients was not interested in receiving telerehabilitation interventions (32%), notably patients with EDSS>4 and non-workers.

CONCLUSIONS

Patients with MS are mainly interested in using telecommunication technologies for rehabilitation services, and most of these patients have access to the required technology. Being mildly disabled and having a professional activity are associated with a greater interest in telerehabilitation. In contrary, patients with moderate-to-severe disability and non-workers have reportedly less access and ease in using the required technologies.

CLINICAL REHABILITATION IMPACT

Telerehabilitation is feasible and wished by patients with MS, specifically in patients with low EDSS scores and workers. Given the strong need for rehabilitation in more disabled patients, the barriers to its access, the lower access and ease of use of telecommunication technologies, a special effort is needed to facilitate their use in these patients.
