Effect of hold and relax technique on knee joint position awareness in normal adults

Abstract

Effect of hold and relax technique on knee joint position awareness in normal. This study investigated whether the hold and relax technique affected knee joint position awareness. Subjects (n = 40) with non-disorder knee joint were randomly allocated into the experimental group (n = 19) and control group (n = 21). This study progressed from the direct method (hold and relax for agonist) and indirect method (hold and relax for antagonist). The hold and relax technique was repeated seven seconds for the isometric contraction and five seconds for the relaxed portion. Awareness of the knee joint position was measured at knee flexion 30°, 60°, 90° and 120° with an isokinetic dynamometer. Significant differences were seen for the mean errors for 30°, 60°, 90° and 120° knee joint position awareness. However, the means showed no significant difference. This study demonstrated that the hold and relax technique has an effect on knee joint position awareness.
