Neuromuscular control strategies may change with age and predispose elderly to knee joint injury. The purposes of this study were to determine if long latency responses (LLR), muscle activation patterns, and movement accuracy differs between the young and elderly during a novel single limb squat (SLS) task. Ten young and ten elderly subjects performed a series of resistive SLS (~0–30 degrees) while matching a computer-generated sinusoidal target. The SLS device provided a 16% body weight resistance to knee movement. Both young and elderly showed significant overshoot error when the knee was perturbed (p < 0.05). Accuracy of the tracking task was similar between the young and elderly (p=0.34), but the elderly required more muscle activity compared to the younger subjects (p < 0.05). The elderly group had larger long latency responses (LLRs) than the younger group (p < 0.05). These results support that neuromuscular control of the knee changes with age, and may contribute to injury.
