Ilium Mobilization in Patellofemoral Pain Syndrome Treatment

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.

Treatment and study plan

posterior ilium mobilization

Other

the therapist will mobilize the innominate on the affected side posteriorly

strengthening and stretching exercises

Other

the participants will receive strengthening exercises on the hip and knee joint beside that they will receive stretching exercises

Primary outcomes

  1. Changes in pain

    Time frame: 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.

  2. Changes in knee functional disability

    Time frame: 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 outcomes

  1. Changes in hip abductors strength

    Time frame: It will be assessed at baseline and after 4 weeks

    Handheld dynamometer will be used to assess changes in muscle strength

  2. Changes in hip extensors strength

    Time frame: It will be assessed at baseline and after 4 weeks

    Handheld dynamometer will be used to assess changes in muscle strength

  3. Changes in hip external rotators strength

    Time frame: It will be assessed at baseline and after 4 weeks

    Handheld dynamometer will be used to assess changes in muscle strength

  4. Changes in knee extensors strength

    Time frame: It will be assessed at baseline and after 4 weeks

    Handheld dynamometer will be used to assess changes in muscle strength

  5. Changes in dynamic knee valgus

    Time frame: 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

  6. Changes in pelvic tilt angle

    Time frame: It will be assessed at baseline and after 4 weeks

    Palpation Meter (PALM) will be used to assess changes in pelvic tilt angle
