Abstract
Objective
To compare a 6-week virtual reality (VR) rehabilitation programme with a conventional rehabilitation programme in patients with Parkinson’s disease.
Design
Prospective, single-blinded, randomised controlled trial.
Setting
Outpatients.
Participants
Fifty-one patients with Parkinson’s disease were assigned at random to a VR rehabilitation programme or a conventional rehabilitation programme.
Interventions
Both programmes ran for 6 consecutive weeks, with a 40-minute session three times per week.
Main outcome measures
The Balance Berg Scale (BBS) was used to measure balance. Secondary outcome measures were: Dynamic Gait Index (DGI) to evaluate ability to adapt gait to complex walking tasks; Disabilities of the Arm, Shoulder and Hand (DASH) scale to measure performance of the upper limb; and Short Form 36 (SF-36) to evaluate quality of life.
Results
The VR rehabilitation programme led to an increase in BBS score {45.6 [standard deviation (SD) 7.9] vs 49.2 (SD 8.1), mean difference 3.6, 95% confidence interval (CI) 1.3 to 5.9; P = 0.003}, DGI score [18.7 (SD 4.7) vs 20.2 (SD 4.2), mean difference 1.6, 95% CI 0.6 to 2.5; P = 0.003] and SF-36 mental composite score [37.7 (SD 11.4) vs 43.5 (SD 9.2), mean difference 5.8, 95% CI 0.4 to 11.3; P = 0.037], and a decrease in DASH scale score [29.6 (SD 17.5) vs 21.6 (SD 15.1), mean difference −7.9, 95% CI −13.7 to −2.2; P = 0.009]. In contrast, the conventional rehabilitation programme only led to a decrease in DASH scale score [30.3 (SD 18.1) vs 25.1 (SD 15.8), mean difference −5.2, 95% CI −8.8 to −1.5; P = 0.007].
Conclusion
These findings suggest that rehabilitation is useful in Parkinson’s disease, and the VR rehabilitation programme was more effective in determining overall improvement than the conventional rehabilitation programme.
