Development and Testing of a Virtual Reality Mirror Therapy System for the Sensorimotor Performance of Upper Extremity: A Pilot Randomized Controlled Trial

Mirror therapy (MT) has been proposed as an essential component of upper limb neurorehabilitation, using mirror illusion the unaffected hand movement and superimposing it on affected to improve neuroplasticity for improving motor recovery in stroke patients. In this paper, we developed a virtual reality (VRMT) system, examined performance VRMT system. The system consists motion-tracking device, VR goggle, software. Young, healthy participants, patients with mild-to-severe hemiparesis were recruited study, validate effectiveness Experimental results based pinch-holding-up activity (PHUA) test revealed significant effect precision pinch young-healthy participants receiving VRMT, whereas traditional MT could not (Wilcoxon signed-rank test, Z = -2.693, p 0.007). For having suffered being treated beneficial effects by mixed model found total score FMA (p 0.033) part 0.008). findings study indicate that potentially positive sensorimotor hands participants. addition, add-on provides function extremity chronic
