Effect of Virtual Reality Training Using Leap Motion Controller on Impairments and Disability in Patients with Wrist and Hand Stiffness
Keywords:Virtual Reality Training, hand rehabilitation, Gaming, distal end forearm fractures.
Background and Purpose: Virtual reality (VR) training targets not only the musculoskeletal, but also the
neurological system and has been successfully used in neurological rehabilitation. Our objective was to test
whether there are any benefits of adding VR training with conventional physiotherapy on impairments and
disability of wrist and hand stiffness, in patients with distal forearm fractures and early rheumatoid hand
Methodology: In this experimental study, 50 patients suffering from wrist and hand stiffness were alternately
allocated into either Conventional physiotherapy group and VR with conventional physiotherapy group.
Both the groups completed 8-12 training sessions over a period of 4 weeks comprising of similar protocol of
conventional physiotherapy with only the VR group receiving additional VR training. Patient was assessed
on outcome measures pre and post treatment.
Results: All the outcome measures showed significant improvement in both groups. On between group
comparisons, the VR group showed significantly greater improvements on the outcome measures of grip
strength, dexterity (left hand and assembly), wrist flexion, ulnar deviation, forearm range of motion and
work component of Michigan Hand Questionnaire when compared to the conventional group. There were
no differences between groups on outcome measure of pain, wrist extension, wrist ulnar deviation and total
disability score of Michigan Hand Questionnaire.
Conclusion: We conclude that, adding virtual reality training to conventional physiotherapy has benefits on
outcome of grip strength, hand dexterity, work component of disability and direction specific improvement
in the range of motion of wrist and forearm as compared to conventional physiotherapy alone.
