Overview
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.
Interventions
- Other Exercise
Exercise with progressively increased range of motion.
Primary outcome measures
- Pain (VAS) [Time frame: Day 1 (Cross sectional single session. Outcomes will be collected during one single session for each participant.)]
- Range of motion [Time frame: Day 1 (Cross sectional single session. Outcomes will be collected during one single session for each participant.)]
Secondary outcome measures (2)
- Force [Time frame: Day 1 (Cross sectional single session. Outcomes will be collected during one single session for each participant.)]
- Tegner Activity Scale (TAS) [Time frame: Baseline (Administered at the beginning of the study)]
Eligibility criteria
Inclusion criteria
- Patients diagnosed with PFP in only one knee by a licensed healthcare professional.
- Aged 15-35 years.
- A physical activity level of 3/10 or higher on the Tegner Activity Scale before the injury.
Exclusion criteria
- Any prior injury or condition with residual symptoms that may affect the results.
- Current injury or condition affecting the performance of the test.
- Resting pain greater than 0-1/10 on the Numeric Pain Rating Scale (NRS) and pain greater than 1-2/10 during light daily activities such as walking, sitting, standing, or climbing stairs.
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
