HealthDay News — For patients with Parkinson disease, high-intensity treadmill exercise seems feasible and safe, according to a study published in JAMA Neurology.

Margaret Schenkman, PhD, from the University of Colorado Anschutz Medical Campus in Aurora, and colleagues conducted a phase 2 trial to examine the feasibility and safety of high-intensity treadmill exercise in patients with de novo Parkinson disease who are not taking medication. Patients with idiopathic Parkinson disease within 5 years of diagnosis were randomized to 6 months of high-intensity treadmill exercise (4 days per week, 80 to 85% maximum heart rate; 43 patients), moderate-intensity treadmill exercise (4 days per week, 60 to 65% maximum heart rate; 45 patients), or wait-list control (40 patients)

The researchers found that the exercise rates were 2.8 and 3.2 days per week at 80.2 and 65.9% maximum heart rate in the high-intensity and the moderate-intensity groups, respectively. The mean change in Unified Parkinson’s Disease Rating Scale motor score was 0.3 and 3.2 in the high-intensity and usual-care groups, respectively (P =.03). Compared with the control group, the high-intensity group, but not the moderate-intensity group, reached the predefined non-futility threshold. There were no severe anticipated adverse musculoskeletal events.
