Wearable Robotic and Virtual Reality on Hand in Stroke

Официальное название

Effects of Wearable Robotic and Virtual Reality-Assisted Interventions on Hand Function in Stroke Rehabilitation

Обзор

Stroke is a common neurological disorder resulting from acute focal damage to the central nervous system due to vascular events such as cerebral infarction, intracerebral hemorrhage, or subarachnoid hemorrhage. It represents one of the leading causes of mortality and long-term disability in adults, with approximately 85 % of cases being ischemic and 15 % hemorrhagic. Among survivors, up to 70 % experience upper-limb functional loss and about 40 % remain chronically impaired, particularly in wrist and hand extension due to synergy patterns and spasticity. Rehabilitation targeting upper-limb motor recovery is therefore crucial for improving activities of daily living and social participation. Technology-assisted interventions such as wearable soft robotic gloves and virtual-reality-based motion-tracking devices have recently been introduced to enhance neuroplasticity, improve voluntary movement quality, and facilitate functional independence. This multicenter, randomized controlled clinical trial will be conducted between November 2025 and June 2026. The study will include adults aged 30-60 years with a confirmed diagnosis of post-stroke hemiplegia (ICD-10: G81) who meet the predefined inclusion criteria-including Mini-Mental State Examination \> 24, Modified Ashworth Scale \< 3, wrist extension \> 10°, Brunnstrom stage \> 3, and Fugl-Meyer Upper-Limb score \> 22-will be recruited after written informed consent. Exclusion criteria include significant neglect or visual deficits, communication disorders, peripheral nerve injury, botulinum toxin injection within the previous six months, major orthopedic surgery of the affected limb, or serious systemic comorbidities. Eligible participants will be randomly assigned to one of three groups for six weeks of therapy, three sessions per week: (1) Neurodevelopmental therapy (NDT) and wearable Soft Robotic Glove (SRG); (2) NDT and Leap Motion Controller (LMC) integrated with the Becure platform (HandROM and ErgoActive modules including LeapBall, Piano, PinchPeg, and Hold-and-Put tasks); or (3) NDT-only control group performing standard task-oriented hand exercises. Assessments will be performed at baseline and after the 18th treatment session and will include demographic data, Box-and-Block Test, Chedoke Arm and Hand Activity Inventory, surface electromyography for muscle strength, and joint-angle measurements using LMC-based Becure HandROM. The primary outcomes of this study are upper-limb functional performance and hand dexterity, while the secondary outcomes include joint range of motion, grip-pattern kinematics, and muscle strength. The findings are expected to compare and determine the effectiveness of wearable soft robotic-assisted and virtual reality-assisted interventions in post-stroke upper-limb rehabilitation, thereby guiding the evidence-based integration of advanced technologies into routine neurorehabilitation practice.
