The Effects of a Strengthening Exercise Program with EMG Biofeedback to Correct Patellar Alignment and Reduces Knee Pain in Women with Patella femoral Pain Syndrome
1. Objective:
The objective of this study was to investigate the effects of a strengthening exercise program with electromyographical (EMG) biofeedback on the alignment corrections of the patella and the knee pain in patients with patella_femoral pain syndrome (PFPS).
2. Design:
This study was a clinical trial. The populations of this study were women with patella femoral pain syndrome.
3. Setting and Conduct:
The participants of this study were 22 females with PFPS. They are randomly divided into two groups: Group 1, including 11, underwent an exercise therapy with biofeedback program and Group 2, including 11, was provided with exercise therapy without biofeedback. The knee pain was quantified by using VAS questionnaire. Radiography technique was also applied to evaluate the knee alignment including sulcus, congruence, tilt angles, and Q angles assessed by clinical tests.
4. Inclusion criteria included
1. Being female
2. Having pain at least in two activities of activities like: going up the stairs, going down the stairs, and squatting.
Exclusion criteri included
1. Having a history of knee pathology except PFPS.
2. Having a previous knee injury or surgery
3. Using anti-inflammatory drugs
5. Intervention:
Receiving visual feedback to strengthen the muscles during exercise
6. Primary Outcome Variables: The results showed that congruence and Q angle weresignificantly reduced in both groups. However, the patellar tilt was significantly reduced only in strengthening exercise program with biofeedback group.
Secondary Outcome Variable: strengthening exercise program with electromyographical biofeedback displayed a better treatment outcome.

Description
Intervention group 1: Strengthening Exercises for knee extensors
These exercises were performed in both experimental groups (I and II) equally. The control group remained sedentary.
The aim of these exercises were to increase the strength of the vastus medialis more than that of the vastus lateralis. Exercises were performed within 18 session with 3 sessions (1.5 hours each session) per week, lasting for 6 weeks.
In the first week, each session were including 3 sets of 10 repetitions (10 seconds each repetition) and the intensity of exercises were increased so that it reached to 5 sets of 30 repetitions at the last week.

Description
Intervention group 2: Biofeedback.
During the exercises, individuals in one of the experimental groups (Experimental I) received biofeedback about the electrical activity of vastus medialis and lateralis. The second experimental group, as well as the control group did not receive any biofeedback. This biofeedback was including an online figure about the peak electromyography signals of the vastus medialis and lateralis muscles online during the exercise and the subject was advised to change her foot position so that the peak value of electrical activity of the target muscle (Vastus medialis) had the largest possible difference with the other muscle.
