Objective: Authors conducted the pilot trial to evaluate whether the virtual reality using mirror therapy induces analgesia and functional improvement to the patients of rheumatoid wrist arthritis.
Method: Three patients with no symptom or sign of active phase at both wrists were recruited. Voluntary range of motion (ROM) of each wrist over as far as possible was recorded and then the same movement was recorded only over 60% of the previous one after break of 5 minutes. For the virtual reality treatment, the second recorded motion was reconstructed into the another one of as same ROM and spent time as the first one, providing confusing visual information to the patients while patients were instructed to reach only the red flags (60% ROM of 1st one). This exercise was repeated for 5 days. Numerous scales such as VAS, ROM, Michigan Hand Outcomes Questionaire (MHQ), Performance and Satisfaction in Activities of Daily Living (PS-ADL), patient-rated wrist evaluation (PRWE) were evaluated before and after repetition.
Results: The increased satisfaction with their hands (satisfaction score of MHQ; 5.8 ± 2.3, [6-30]), improved ADL performances (PS-ADL score: 5.0 ± 3.5, [0-117]), and no side effect were noticed.
Conclusion: The virtual reality using mirror therapy may be safe and has some analgesic effect, which warrants a clinical trial in the future for the patients of rheumatoid wrist arthritis.
