Mobile game-based virtual reality rehabilitation program for upper limb dysfunction after ischemic stroke.

BACKGROUND: Virtual reality (VR) has the potential to provide intensive, repetitive, and task-oriented training, and game-based therapy can enhance patients’ motivation and enjoyment. OBJECTIVE: The objective of the present study was to develop a mobile game-based upper extremity VR program for patients who have experienced stroke, and to evaluate the feasibility and effectiveness of the program. METHODS: This randomized, double-blind, controlled trial included 24 patients with ischemic stroke. The intervention group (n =12) received 30 min of conventional occupational therapy (OT) and 30 min of the mobile upper extremity rehabilitation program using a smartphone and a tablet PC (MoU-Rehab). The controls (n =12) received conventional OT alone for 1 h per day. Rehabilitation consisted of 10 sessions of therapy, 5 days per week, for 2 weeks. The outcome measures (Fugl-Meyer Assessment of the upper extremity [FMA-UE], Brunnstrom stage [B-stage] for the arm and the hand, manual muscle testing [MMT], modified Barthel index [MBI], EuroQol-5 Dimension [EQ-5D], and Beck Depression Inventory [BDI]) were assessed at the beginning and end of treatment, and at 1 month. User satisfaction was evaluated by a questionnaire. RESULTS: A greater improvement in the FMA-UE, B-stage, and MMT was found after treatment with the MoU-Rehab than with conventional therapy. The extent of improvements in the MBI, EQ-5D, and BDI was not significantly different between the two groups. Patients in the experimental group completed the 2-weeks treatment without adverse effects, and they were generally satisfied with MoU-Rehab. CONCLUSION: This mobile game-based VR rehabilitation program appears to be feasible and effective for promoting upper limb recovery after ischemic stroke.
