Brief summary of evidence supporting the efficacy of biofeedback for subluxation of the patella:

LeVeau and Rogers (1980) found that the vastus medialis could be trained to contract independently of the vastus lateralis using EMG biofeedback. Ingersoll and Knight (1991) found that normal people (thirty college women) could be trained with EMG biofeedback to control the position of the patella sufficiently that "the use of EMG biofeedback training to selectively strengthen the vastus medialis oblique appears to be essential in correcting faulty patellar tracking." Sherman (2004) summarized the data supporting use of this technique and detailed the methodology involved.
