The Effects of Exercise-induced Fatigue on Knee Joint Position Sense in the Young, Elderly Adults and Stroke Patients

The subjects were recruited into three groups; young group(YG)(N=15), elderly group(EG)(N=15), and stroke group(SG)(N=15). Exercise-induced fatigue was achieved by repeated active exer cise 60 times on an angle at 10 to 100 degrees of the knee joint with an angle speed of 120°/s, with three sets for 15 minutes. Evaluation was performed for determination of repositioning error using passive angle repositioning (PAR) and active angle repositioning (AAR).
