简要总结
Pain at the front of the knee is a common condition treated by physical therapists. Treatment may consist of generalised strengthening exercises directed at the quadriceps muscle or specific retraining aimed at restoring motor control at the knee. This study compared these two exercise programs in a group of people who were painfree at the time to evaluate their effect on motor control. It was hypothesised that only the motor retraining program would influence motor control at the knee.
