Effects of Virtual Reality Versus Whole-Body Vibration on Muscle Strength and Balance in Children with Duchenne Muscular Dystrophy: a Randomized Controlled Trial.

What was studied

This trial compared virtual reality with whole-body vibration. Children had Duchenne muscular dystrophy and could walk. 50 boys aged 6-10 years took part. They were split 1:1 into 2 groups of 25. Both groups did the same physical therapy for 12 weeks. One group added 10 min of video-game training. The other added 10 min of vibration. The main outcome was quadriceps strength. Balance was also measured.

What they found

At 12 weeks, the VR group improved more than the vibration group. This held for right and left quadriceps strength. It also held for overall, front-back and side-to-side balance. Tests were done at baseline, 6 weeks and 12 weeks. Assessors did not know the group. A correction for multiple tests was used. No adverse events were reported.

What it means for patients

The authors say VR gave greater gains in quadriceps strength and balance. They see VR as a motivating add-on to physical therapy.

Why it is not certain yet

The authors say functional outcomes need study. Longer follow-up is needed. All boys came from one clinic. They could walk and were aged 6-10 years. Results may not apply to others.
