Hemiparesis is a common movement disorder following a stroke, where many patients struggle to regain functional use of their affected upper limb. Researchers are evaluating whether using mirror therapy through an Intensive Visual Simulation (IVS) device can improve motor function and abilities in the affected hand and wrist during the sub-acute phase of stroke, between 4 and 10 weeks after the event. This study is a randomized controlled trial comparing IVS therapy to conventional rehabilitation care for patients with moderate to severe hemiparesis. The IVS3 device creates an immersive mirror therapy experience by filming the unaffected upper limb and projecting its mirrored image onto a screen above the affected arm, creating the illusion of movement in the paralyzed limb. Participants receive 6 weeks of treatment where part of their routine occupational therapy is replaced with structured movement repetition programs using the IVS3 device. The therapy progresses from observation and mental practice in the first week to analytical wrist and finger movements in weeks two and three, and then functional tasks like object manipulation and gripping from week four onward. The control group receives conventional upper limb rehabilitation involving stretching, postural exercises, assisted and active movements, and gripping tasks. Participants are involved in treatment sessions over 6 weeks, starting between 4 and 10 weeks after stroke. Researchers assess motor performance using the Fugl-Meyer wrist/hand sub-score at the start and end of the program to measure changes. The study lasts 18 weeks per participant and includes monitoring for any discomfort or fatigue during device use. No major risks beyond daily life activities are expected. The study aims to determine if the IVS device can enhance motor recovery and functional use of the affected upper limb compared to standard rehabilitation alone.
