RESULTS: What the researchers referred to as “forced rate activity,” others might feel is more accurately labeled “torture.” But when they calculated the brain activation of the patients forced to pedal past their comfort level, they found lasting increases in connectivity between two areas of the brain responsible for motor ability: the primary motor cortex and the posterior region of the thalamus.
CONCLUSION: Forced-rate bicycle exercise appears to be an effective therapy for Parkinson’s disease.
