Comparative Effects Of Clamshell And Short Arc Quadriceps Exercises In Patellofemoral Pain
Sponsor: Green International University
Summary
This is a research study to compare two different exercises for people who have patellofemoral pain syndrome. Patellofemoral pain syndrome means pain around or behind the kneecap, which is also called "runner's knee". People in this study will be divided into two groups by chance. One group will do clamshell exercises. This exercise strengthens hip muscles. The other group will do short arc quadriceps exercises. This exercise strengthens thigh muscles near the knee. Both groups will do their exercises for the same number of weeks. The main goal of this study is to see which exercise reduces knee pain better and helps patients do daily activities more easily. We will also check if quality of life improves after doing these exercises. Pain level, knee function, and quality of life will be checked before starting exercises and again after finishing the exercise program. The results may help doctors and physical therapists choose the best exercise for patients with kneecap pain.

Clamshell Exercise
A hip strengthening exercise performed in side-lying position with hips and knees flexed. Patient opens top knee like a clamshell while keeping feet together to strengthen gluteus medius and external rotators.
Short Arc Quadriceps Exercise
A knee strengthening exercise performed in short range of motion from 30 degrees to full extension. Patient extends knee against resistance while quadriceps muscle is activated, focusing on vastus medialis obliquus.
