Description of intervention(s) / exposure
BEHAVIORAL - Motor control retraining program
BEHAVIORAL - Quadriceps strengthening program

Experimental: 1 - Motor control retraining program


BEHAVIORAL: Motor control retraining program
Specific retraining of VMO activation in a low-load situation,and progressed to integrate more functional positions. Use of dual channel biofeedback was incorporated

BEHAVIORAL: Quadriceps strengthening program
4 exercises focused on quadriceps strengthening commencing at a resistance of 60% 1 repetition maximum. Each exercise was performed for 3 sets of 10 repetitions

Summary
Brief summary
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.
