Brief Summary

Purpose: to investigate the effect of proximal stability on PF OA. Methods: Thirty patients with PF OA will be recruited. Patients will be randomly assigned into two groups, group A and group B . Patients in both groups will receive a traditional physical therapy treatment, but group (B) will receive additional proximal stability exercise. All patients will be evaluated for muscular recruitment strategies (onset and duration) of multifidus, transversus abdominus (TrA), gluteus medius (GM), and vasti measured by quantitative Electromyography during stair descent. pre and post-treatment.

Study Arms (2)

group A

OTHER

Patients in this group will receive a traditional therapeutic knee rehabilitation program in the form of mini-squatting exercise (up to 45 degree knee flexion measured by a universal goniometer) , strengthening of hip abductors and external rotators

Other: traditional knee rehabilitation program

group B

EXPERIMENTAL

Patients in this group will receive the same program as group (A) plus proximal stabilization exercise

Other: traditional knee rehabilitation program; Other: proximal stabilization

Interventions

traditional knee rehabilitation program OTHER

Patients in this group will receive a traditional therapeutic knee rehabilitation program in the form of mini-squatting exercise (up to 45 degree knee flexion measured by a universal goniometer) , strengthening of hip abductors and external rotators

group A; group B

proximal stabilization OTHER

the principles of proximal stability will be explained to patients before initiation of treatment and patients will be asked to comply with these principles during exercise. These principles include learning how to activate transversus abdominus by abdominal bracing without allowing pelvis tilting and ensure neutral spine and diaphragmatic breathing during exercise.

Eligibility Criteria

• Age: 35 Years - 55 Years
• Sex: female
• Healthy Volunteers: No
• Age Groups: Adult (18-64)

You may qualify if:

• Anterior- or retro-patellar knee pain aggravated by at least two activities that load the PFJ (eg; stair ambulation, squatting and/or rising from sitting) .
• Pain during these activities presented on most days during the past month and their pain severity was ≥ 4 on an 11 point numerical pain scale during aggravating activities .,
• A grade less than (2) from postero-anterior views on the Kellgren - Lawrence (KL) grading scale.

You may not qualify if:

• concomitant pain from tibiofemoral joint or other knee structures .
• current or previous pain in the hip, lumbar spine or foot that had lasted longer than 3 months and/or required intervention.
• a history of lower extremity, pelvis or spine fractures; spine, hip, knee or foot surgeries; hip or patellar subluxation/ dislocation.
• injury to any of knee ligaments or meniscus.
• systemic diseases (e.g. rheumatoid arthritis), neurological conditions or fibromyalgia .
• The professional athletes; people who exercise more than two hours a day or every other day, will be excluded.
