Effects of Virtual Reality Based Aerobic Exercise on Pulmonary Function and Cardiopulmonary Fitness in Parkinson's Disease: A Pilot Randomized Controlled Trial.

In 30 seconds

This single-blinded pilot randomized controlled trial evaluated Wii Fit Plus aerobic exercise in 30 people with Parkinson’s disease (Hoehn and Yahr stages II–III) and respiratory impairment. Participants were assigned to supervised exercise three times weekly for 12 weeks or usual activity. Compared with controls, the exercise group had significant group-by-time improvements in spirometric measures, peak oxygen uptake, and perceived dyspnea; peak heart rate did not differ significantly (P = 0.071). Program adherence was 92%, with no reported adverse events. The findings suggest potential benefit and feasibility, but larger trials are needed to confirm efficacy and longer-term outcomes.

Key findings

• The exercise group improved in FVC (P = 0.018), FEV₁ (P = 0.021), FEV₁/FVC (P = 0.039), and PEF (P = 0.011).
• Peak oxygen uptake improved with exercise (P = 0.004), while peak heart rate showed no significant difference (P = 0.071).
• Perceived dyspnea outcomes improved: Borg RPE (P = 0.006) and mMRC (P = 0.028).
• Adherence to the exercise program was 92%, and no adverse events were reported.

Why it matters

Respiratory impairment can contribute to exercise intolerance and morbidity in Parkinson’s disease. These pilot findings indicate that supervised, game-based aerobic exercise may improve pulmonary function, aerobic capacity, and perceived dyspnea in this population. The results also provide preliminary feasibility and safety information, while the small pilot trial does not establish the size or durability of benefit.

What to keep in mind

This was a pilot trial involving 30 participants with Parkinson’s disease at Hoehn and Yahr stages II–III and respiratory impairment. Outcomes were assessed after the 12-week intervention; long-term outcomes were not established.
