Patellofemoral Pain Syndrome
Conditions
Keywords
patellofemoral pain syndrome, strength, stretch, mobilization, ilium, innominate
Brief summary
Aim of the study is to investigate the effect of adding posterior ilium mobilization on knee pain, knee function, anterior pelvic tilt, dynamic knee valgus, muscle strength of extensors, abductors and external rotators of hip and knee extensors in patients with patellofemoral pain syndrome.
Interventions
the therapist will mobilize the innominate on the affected side posteriorly
the participants will receive strengthening exercises on the hip and knee joint beside that they will receive stretching exercises

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Changes in pain | It will be assessed at baseline and after 4 weeks | Arabic Numeric pain rating scale will be used to assess pain changes during walking, hopping, squatting, stair negotiation, kneeling, or prolonged sitting. This scale measures pain severity on a scale of 0 to 10 points, with 0 representing no pain and 10 signifying the most severe pain possible. |
| Changes in knee functional disability | It will be assessed at baseline and after 4 weeks | The Arabic version of Anterior knee pain scale will be used to assess the knee functional disability. It is a self-administered, weighted questionnaire that analyzes 13 items, including pain and function, with a maximum score of 100 points and minimum score of 0 points. Higher scores indicate greater lower extremity function. It documents responses to six activities linked with anterior knee pain (walking, running, jumping, climbing stairs, squatting, and sitting for prolonged periods with knee bent). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes in hip external rotators strength | It will be assessed at baseline and after 4 weeks | Handheld dynamometer will be used to assess changes in muscle strength |
| Changes in knee extensors strength | It will be assessed at baseline and after 4 weeks | Handheld dynamometer will be used to assess changes in muscle strength |
| Changes in hip abductors strength | It will be assessed at baseline and after 4 weeks | Handheld dynamometer will be used to assess changes in muscle strength |
| Changes in pelvic tilt angle | It will be assessed at baseline and after 4 weeks | Palpation Meter (PALM) will be used to assess changes in pelvic tilt angle |
| Changes in dynamic knee valgus | It will be assessed at baseline and after 4 weeks | Cell phone Camera, tripod device and Kinovea Computer Program (KCP) will be used to assess knee frontal plane projection angle to detect changes in knee valgus during step down test |
| Changes in hip extensors strength | It will be assessed at baseline and after 4 weeks | Handheld dynamometer will be used to assess changes in muscle strength |
