Parallel Randomized Feasibility Trial of Occupational Therapy Virtual Reality Training for Stroke Patients

Recent investigations have brought Virtual Reality Training (VRT) to the forefront as a promising computer-based therapy for stroke patients, showing positive effects on arm function, balance, and walking recovery (Laver et al., 2017; Saposnik et al., 2016). Nevertheless, the challenges faced by stroke patients in accessing outpatient therapy after leaving inpatient rehabilitation, primarily due to transportation, distance, and lengthy waiting lists, have not gone unnoticed. In response, home-based VRT has emerged as a convenient and accessible alternative. This parallel randomized feasibility trial aims to accomplish two primary objectives: (1) evaluating the practicality of implementing VRT for stroke patients at home, and (2) assessing the feasibility of using various quantitative and qualitative outcome measures to gauge stroke recovery (Palmer et al., 2019). By exploring the potential of home-based VRT, this trial seeks to illuminate its effectiveness as a rehabilitation strategy, ultimately enhancing the overall recovery process for stroke patients. The study will comprehensively assess multiple aspects, including compliance, safety, enjoyment, perceived efficacy, and program cost, to determine the effectiveness and feasibility of home-based VRT for stroke patients nearing discharge from rehabilitation. Evaluations for balance, gait, and community integration will be conducted, with effect sizes analyzed to gauge the impact of the intervention. A total of forty participants will be randomly assigned to either the experimental group, engaging in VRT for rehabilitative exercises, or the control group, utilizing selected iPad apps. Both groups will undergo 30-minute exercise sessions, five days a week, for a period of six weeks. The intensity of VRT will be remotely monitored, with regular telephone contact maintained with all participants. Building on the findings of this trial, a definitive randomized controlled trial will be conducted to gain deeper insights into the use of VRT as a rehabilitative tool for post-stroke patients. This comprehensive and rigorous trial aims to establish the efficacy of home-based VRT in enhancing physical and cognitive functions for stroke patients. The results will provide robust evidence for the integration of VRT into stroke rehabilitation programs, potentially setting new standards of care for post-stroke patients. Moreover, the research could yield invaluable insights into the advantages and limitations of home-based VRT, paving the way for the development of more effective and accessible home-based rehabilitation programs. Ultimately, the study’s findings will serve as evidence to support the development of a conclusive randomized controlled trial, thoroughly examining the effectiveness of home-based Virtual Reality Training (VRT) in stroke rehabilitation.
