Upper Limb Telerehabilitation With Virtual Reality in Multiple Sclerosis

Approximately 60% of people with multiple sclerosis (pwMS) suffer from upper limb dysfunction. The primary goal of this study is to implement a single-blind, randomized control trial (RCT) designed to compare the effectiveness of an 8-week home-based telerehab virtual reality (VR) program with conventional therapy in pwMS with manual dexterity difficulties. Secondary aims include; a) evaluating the impact of the programs on quality of life after the intervention and a follow up 1 month later; and b) evaluating the impact of the programs on adherence and satisfaction. Methodology. Twenty-four pwMS will be recruited to participate in the study which will be conducted at two established MS Centers: (1) The Sardinian Center for Diagnosis and Treatment of Multiple Sclerosis, Binaghi Hospital, Cagliari, Italy; (2) The Multiple Sclerosis Center, Sheba Medical Center, Tel-Hashomer, Israel. Participants will complete a total of three assessments focusing on upper limb functions. Both groups will receive 16 training sessions focusing on functional upper limb activities. The home-based telerehab VR intervention will comprise a custom-made software program running on a private computer or laptop. pwMS will perform several activities of daily living (ADL) functions associated with self-care, dressing and meal preparation. Conventional therapy will focus on task-related upper-limb treatments while in a sitting or prone position, indicative of the standard care in multiple sclerosis (MS). Following 8-weeks of training, participants will complete a further outcome assessment. The same tests will be conducted 1 month (as a follow-up) after completion of the intervention. Potential scientific contribution. The outcomes of this study have tremendous potential to improve the quality of evidence and informed decisions of functional upper limb activities in pwMS. If comparable results are found between the treatments in improving upper limb outcomes, this would suggest that pwMS can choose the program that best meets their personal needs, e.g., financial concerns, transportation or accessibility issues. Secondly, this information can be used by healthcare providers and medical professionals in developing upper limb exercise programs that will most likely succeed in pwMS and will then be disseminated to neurologists and other medical providers. Mode of cooperation and added value. The Italian group will be responsible for designing and implementing three new VR scenarios relating to functional activities of the upper limb. The new VR scenarios will be planned in conjunction with the Israeli group who will also play an active role in the quality assessment procedures of the developed elements. Both groups will participate equally in the pilot RCT. Roles include: recruitment and guidance of patients and therapists, implementing the telerehab VR system in the patient's home, assessment of outcome measures, data collection, analysis and interpretation of data and dissemination of the findings. An additional role of the Israeli team will be to prepare a user manual detailing how to use the system and providing clinical guidelines/recommendations for both the therapist and patient.
