Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to investigate the relationship between knee joint range of motion and pain in patients with patellofemoral pain syndrome (PFPS). In a cross-sectional observational design, PFPS patients will perform trials involving progressively increased knee joint range of motion in three closed-chain exercises: squat, single-leg squat, and split squat. During each trial, participants will report pain levels on a 0-10 Visual Analog Scale (VAS) until either (1) achieving full depth in the respective exercise or (2) reaching a pain level of \>5 on the VAS.
