The effects of a self-supervised home exercise program and a physiotherapist-supervised exercise program on motor symptoms in Parkinson's disease (PD) patients were compared in a prospective single-blinded clinical trial. Nineteen subjects (6 women, 13 men; mean age, 65 +/- 8 years) with Hoehn and Yahr Stages 2 to 3 were recruited. Subjects were(More)
BACKGROUND Identification of mechanical factors associated with patellofemoral pain, the most prevalent running injury, is necessary to help in injury prevention, but unfortunately they remain elusive. HYPOTHESIS Runners who develop patellofemoral pain have increased knee joint angular impulse in the frontal plane. STUDY DESIGN Case control study; Level(More)

Caffeine is a proven ergogenic aid, increasing athletic performance, endurance, and mental chronometry at doses as low as 1-3 mg.kg-1. As coffee is a readily available and commonly ingested form of caffeine, the two are often equated. However, coffee also contains hundreds of other biologically active compounds, many of which are metabolically distinct from(More)
