Effect of sensorimotor agility exercise and associated detraining on Parkinson’s disease symptoms


  • A short-term, high-intensity sensorimotor agility exercise program resulted in Parkinson’s disease (PD) symptom improvement for up to 1 year after completion, but a maintenance program was needed to increase or sustain symptom, quality-of-life (QOL), and medication improvements.

Why this matters

  • Physical activity has been used complementary to medications to reduce motor and non-motor PD symptoms and improve QOL, but it is unclear whether high-intensity exercise is safe, how long beneficial effects last, and whether maintenance exercise prolongs symptom improvement.

  • This study provides support that a short bout of high-intensity exercise is not only safe, but also lasts up to a year, and symptoms continue to improve with exercise maintenance, advocating for exercise programs in PD treatment plans.
