•A review of 14 studies on treadmill training found that three studies show an immediate effect of increased walking speed, longer stride length and improved balance as early as after one treadmill session. Longer-term trials, numbering 11 in all, demonstrated not only safety, but positive benefits in gait speed, strike length and related quality of life even several weeks later.
•And at the Cleveland Clinic, Dr. Alberts et al. found that when people with Parkinson’s pedaled on a stationery bike 30% faster than their preferred “voluntary” rate (or forced exertion), they not only gained in aerobic fitness, but also showed improvement in motor function and coordination as well as manual dexterity. This improvement was retained some weeks after the exercise stopped.
