360 Degrees Virtual Reality-based Mirror Therapy for Stroke Patients

Participants will receive mirror therapy using a virtual reality device (Pico G2 VR 4K, Pico, China). They will be asked to follow tasks that are played in HMD using their paralyzed hand. The video played using HMD will be video taped using 360 degree camera prior to the treatment. The 360MT will last 30 minutes/session, 3 sessions a week for 4 weeks. The tasks are finger flexion-extension, wrist flexion-extension and pronation-supination, and elbow flexion-extension for ten repetitions.

Participants will receive mirror therapy using an acrylic mirror (40cm x 40cm x 3cm) that reflects unparalyzed side of them. They will be asked to perform tasks including finger flexion-extension, wrist flexion-extension and pronation-supination, and elbow flexion-extension for ten repetitions. They will be asked to follow the reflection on mirror using their paralyzed limb. The TMT will last 30 minutes/session, 3 sessions a week for 4 weeks.

Participants will receive conventional physical therapy including neurodevelopmental therapy, muscle strengthening exercises, and joint mobilization which will be provided 60 minutes per day, 5 sessions a week, for 4 weeks.
