Ilium Mobilization in Patellofemoral Pain Syndrome Treatment

Not Applicable

Completed

• Conditions: Patellofemoral Pain Syndrome
• Interventions: Other: posterior ilium mobilization; Other: strengthening and stretching exercises

• Registration Number: NCT05708495
• Lead Sponsor: Cairo University

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.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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 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 hip 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 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 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 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
