Cycling ability maintained in Parkinson's disease patients with freezing of gait

TORONTO - A study investigating the use of cycling in Parkinson's disease patients with freezing of gait was presented today at The Movement Disorder Society's 15th International Congress of Parkinson's Disease and Movement Disorders.

The study, led by Anke Snijders, MD, of Nijmegen, the Netherlands, shows cycling to be less affected than walking when used as a physical rehabilitation method for patients with freezing of gait in Parkinson's disease.

Of the 53 Parkinson's disease patients interviewed for the study, 23 experienced freezing of gait. Only one of those 23 patients experienced episodes of freezing of gait while cycling, though it was less severe than during walking. Eight of the patients with freezing of gait reported that the feet sometimes exerted an irregular pressure on the pedals, but without obvious obstruction.

Daniel Tarsy, MD, of Beth Israel Deaconess Medical Center in Boston, states, "Recent anecdotal reports indicate that patients with Parkinson's disease who suffer from gait freezing can ride a bicycle much more easily than they can walk. The study by Snijders indicates this may be a relatively common phenomenon. Only one of 23 patients who reported gait freezing experienced similar difficulty while cycling. If this can be confirmed by direct observation, it indicates that individuals with gait freezing can enjoy useful physical exercise. Whether this occurs by utilizing an alternative motor system, taking advantage of sensory cues provided by rotating bike pedals, or by other mechanisms, is of great interest and will be worth investigating."

In addition to maintained motor function, cycling promotes physical activity among patients, which can prevent other complications of immobility in Parkinson's disease.
