The comparison of effectiveness of open and closed kinetic chain exercise in reducing knee pain and improving the normal function of the patients with patellofemoral pain syndrome
The purpose of this study is to compare the effectiveness of open and closed kinetic chain exercise therapy in reducing knee pain and improving the normal function of the patients with patellofemoral pain syndrome. This study will be done as the single-center randomized clinical trial in patients with patellofemoral pain syndrome, referred to Rasool-e-Akram hospital. Inclusion criteria are anterior knee pain for at least two months, Positive Clark's test, induction of the pain in up or down stairs and other knee full flexion situations. Exclusion criteria are knee osteoarthritis and other associated problems of the knee. In this study 64 patients eligible for inclusion, will be divided in two groups by block randomization. The first group will receive open-kinetic chain exercises and the second the closed-kinetic chain exercises. The open chain exercises group will do quadriceps static contraction and straight leg raising exercises. The closed chain exercise group will do semi squat, wall slide and step ups. The patient's pain and function will be assessed pre intervention , one and two months post intervention by Visual Analogue Scale ruler, Kujala and Functional Index questionnaires.

Description
The patients in open chain exercises group will do static quadriceps contraction and the Straight leg raising exercises for two months.In the first week, they will do the exercises two times a day with ten repetitions, the hold time of static contraction will be ten seconds.The exercise therapy program will be progressed to three times a day in the second week and three times a day with 15 repetitions in the third week.
At the fourth week, the exercise therapy program will be progressed to three times a day and the hold time of static contraction will be 15 seconds. The progression of exercise therapy will continue in the same way until the end of the 8th week.
