Comparing 3D Virtual Reality and Motor Imagery for Upper Limb Recovery After Stroke

What this Trial Is About

Researchers are investigating the effects of three-dimensional immersive virtual reality IVR therapy compared to motor imagery and conventional physiotherapy on upper extremity functional recovery after stroke. The study focuses on stroke patients who have experienced the condition within the last two years and aims to understand how these different therapies impact brain function and recovery. The trial explores whether imagining movements or interacting with virtual environments can enhance rehabilitation outcomes. Participants are randomly assigned to one of three groups immersive virtual reality therapy, motor imagery, or conventional physiotherapy. The IVR group uses Oculus Rift and Leap Motion devices to engage in task-oriented games for 45 minutes, three days a week over six weeks. The motor imagery group watches videos of these games and imagines performing the movements with eyes closed, also three days a week for six weeks. The physiotherapy group receives routine rehabilitation including joint movements, muscle strengthening, balance, and daily activity exercises five days a week for six weeks. Throughout the study, participants undergo assessments before treatment, immediately after, and at six weeks. These include the Modified Ashworth Scale, Functional Independence Scale, self-care questionnaires, Action Research Arm Test, and Fugl-Meyer upper extremity motor evaluations. Primary outcomes measured at six weeks include the Jebsen Hand Function Test and Action Reach Arm Test. Secondary outcomes involve the Stroke Impact Scale and Kinesthetic and Visual Imagery Questionnaire. The study monitors functional progress and safety, aiming to provide detailed data on the effectiveness of these rehabilitation methods over the six-week period.
