Summary:
Researchers report that the ability to ride a bike can differentiate between atypical parkinsonism and Parkinson's disease, regardless of the environment or situations for bicycling.

In a new study published October 6 in the Journal of Parkinson's Disease, Japanese researchers report that the ability to ride a bike can differentiate between atypical parkinsonism and Parkinson's disease, regardless of the environment or situations for bicycling.

Atypical parkinsonisms are disorders that look similar to Parkinson's disease, but respond differently to treatments. The "bicycle sign" can help clinicians differentiate between the two. Patients with atypical parkinsonism lose their ability to cycle during the early phase of the illness, while patients with Parkinson's disease continue to ride well. Actual environments or situations for biking differ from one country to another, raising the question of whether the "bicycle sign" could be universally applicable. Hideto Miwa and Tomoyoshi Kondo, of the Department of Neurology at Wakayama Medical University, in Wakayama, Japan, set out to determine if the "bicycle sign" would be reliable in Japan, where the roads are hilly, narrow, and crowded with automobiles.

The study found that 88.9% of Japanese patients with atypical parkinsonism had ceased bicycling during the few years around the onset of their illness, as compared with only 9.8% of the patients with Parkinson's disease. In fact, the prevalence of the "bicycle sign" may be much higher in Japan than in The Netherlands (51.5%), which is known as one of the world's most bicycle-friendly countries. This may be because the tough bicycle environment in Japan makes it more difficult for atypical parkinsonism patients to bike.

"Although bicycling cultures may differ between countries, it is possible that the 'bicycle sign' could contribute to earlier and better differential diagnosis of parkinsonism during the diagnostic interview. When we see patients with parkinsonism without a definitive diagnosis, it is a simple thing to ask the question, 'Can you still ride a bicycle?'" commented Dr. Miwa.
