Brief summary
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
Exercise with progressively increased range of motion.

Eligibility
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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain (VAS) | Day 1 (Cross sectional single session. Outcomes will be collected during one single session for each participant.) | Pain measured 0-10 visual analog scale (VAS) reported during each trial of progressively increased range of motion during a single session. |
| Range of motion | Day 1 (Cross sectional single session. Outcomes will be collected during one single session for each participant.) | Degrees of knee flexion measured during each trial in one single session. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Force | Day 1 (Cross sectional single session. Outcomes will be collected during one single session for each participant.) | Force (N) (peak value) reported during the different trials in one session. Measured by force plates. |
| Tegner Activity Scale (TAS) | Baseline (Administered at the beginning of the study) | The Tegner Activity Scale (TAS) will be used to assess the physical activity levels of the participants. Scale from 1-10 where 10 is highest possible physical activity and 1 is sedentary. |
