Efficacy of Tele-Rehabilitation for Post-Stroke Upper Limb Recovery in Rural Areas

Thesis Abstract

Stroke-related upper limb impairment remains a critical barrier to functional independence in rural populations, where access to in-clinic rehabilitation is limited by distance, transportation, and resource constraints. This study addresses the gap by evaluating the efficacy of a tele-rehabilitation program designed to enhance motor recovery, functional performance, and participation for adults with post-stroke upper limb paresis in rural settings. The aim is to determine whether tele-rehabilitation delivers non-inferior outcomes compared with conventional in-person therapy and to identify contextual facilitators and barriers to implementation in low-resource rural communities. Objectives include (1) to compare upper limb motor function outcomes between tele-rehabilitation and standard care over a 12-week intervention; (2) to examine changes in activities of daily living and participation using validated measures; (3) to assess adherence, satisfaction, and engagement with tele-delivery modalities; (4) to explore patients’ and therapists’ experiences to elucidate determinants of program success or failure; and (5) to perform a preliminary cost-effectiveness analysis from a health-system perspective. The study adopts a multicenter, parallel-group, randomized controlled trial with embedded qualitative components, guided by the International Classification of Functioning, Disability and Health (ICF) framework and the Self-Efficacy Theory to explain adherence to remote exercises. The population comprises adults aged 40–85 years, 6–18 months post-stroke, residing in rural districts with access to internet-enabled devices. A sample of 180 participants will be recruited from five rural rehabilitation sites and randomly allocated (11) to tele-rehabilitation or conventional therapy, with stratification by baseline motor impairment (Fugl-Meyer Assessment for Upper Extremity score) and time since stroke. The tele-rehabilitation group will receive a 12-week, thrice-weekly program combining synchronous videoconferencing sessions with guided home exercises, real-time feedback, and a culturally adapted digital coaching interface, plus asynchronous messaging support. The control group will receive standard in-person outpatient therapy following local protocols. Data collection will utilize validated instruments at baseline, week 6, week 12 (end of intervention), and a 3-month follow-up primary outcome will be the upper extremity motor function assessed by the Fugl-Meyer Assessment for Upper Extremity (FMA-UE); secondary outcomes include the Box and Block Test (BBT) for gross dexterity, the Wolf Motor Function Test (WMFT) time-based score, the Motor Activity Log (active use), the Stroke Impact Scale (SIS-UE domain) for participation and quality of life, and the System Usability Scale (SUS) for tele-rehabilitation acceptability. Adherence metrics will be captured through platform usage data, completion rates, and wearables-derived movement counts. An economic evaluation will estimate incremental cost per quality-adjusted life year (QALY) gained using a health-care payer perspective. Quantitative analyses will employ mixed-effects linear models to assess trajectories over time, controlling for baseline impairment and covariates such as age, sex, and comorbidities. Non-inferiority margins will be defined a priori for the primary outcome. Secondary outcomes will be analyzed with repeated-measures ANOVA and logistic regression for adherence and satisfaction indicators. Mediation analyses will test whether self-efficacy and usability mediate the relationship between intervention type and functional outcomes. Qualitative data from semi-structured interviews with a purposive subsample of 40 participants and 12 therapists will undergo thematic analysis to identify contextual factors influencing implementation, with triangulation against quantitative findings. Thematic coding will be guided by the Normalization Process Theory to understand integration into routine practice. Expected findings anticipate that tele-rehabilitation will produce improvements in FMA-UE and WMFT comparable to conventional therapy, with higher adherence in rural participants due to reduced travel burden. It is hypothesized that gains in functional activity (BBT, WMFT) will translate into enhanced participation and perceived activity effectiveness (SIS-UE). Usability and acceptability are expected to be favorable, contingent on reliable connectivity and user-centered design. The study will contribute to knowledge by providing rigorous evidence on the effectiveness and feasibility of remote motor rehabilitation for rural stroke survivors, informing policy on scale-up, and identifying critical determinants for successful implementation in resource-constrained settings. The main conclusion anticipated is that well-structured tele-rehabilitation can achieve clinically meaningful motor and functional gains without compromising safety, with cost-effectiveness favorable under scalable delivery models. Recommendations include investment in rural digital infrastructure, training of local therapists in tele-delivery, development of adaptive algorithms for personalized exercise progression, and policy guidance on reimbursement for remote rehabilitation services.
