Typically, a patient with Parkinson's riding a bike maintains a pedaling rate of around 50-60 RPMs.
With Parkinson's, however, these special nerve cells break down, the supply of dopamine dwindles, and movement is affected.
Parkinson's wreaks havoc by affecting nerve cells in the brain that make the neurotransmitter called dopamine.
