See Xiang et al. (doi:10.1093/brain/awy250) for a scientific commentary on this article. Balance impairment in Parkinson's disease decreases quality of life and is often refractory to treatment.

The deficits may be reversible with the experimental therapy, pedunculopontine nucleus deep brain stimulation.
