Descriptive Information

Brief Title ^ICMJE

A Comparison of Two Exercise Programs on Knee Motor Control

Official Title ^ICMJE

The Effect of Specific Versus Generalised Quadriceps Exercise on Neural Control of the Vasti

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.

Condition ^ICMJE

Knee Pain
Patellofemoral Pain

Intervention ^ICMJE

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
