Pilates-based Core Strengthening on Patellofemoral Pain Syndrome

Not Applicable

Completed

• Conditions: Patellofemoral Pain Syndrome

• Registration Number: NCT05120583
• Lead Sponsor: Qassim University

Brief Summary

Patellofemoral pain syndrome (PFPS) is one of the most common musculoskeletal pain conditions that tend to become a chronic problem. PFPS is common among young adolescents, particularly in physically active individuals aged 12 to 17 years old with more prevalence among females, as it affects females 1.5 - 3 times when compared to males.

Detailed Description

Adolescents with PFPS usually complain of retro-patellar pain (behind the kneecap) or peripatellar pain (around the kneecap) and crepitation in the knee joint, and also there is discomfort while sitting with a flexed knee for a long time. Symptoms are usually exacerbated by activities that increase the load on patellofemoral joints such as weight-bearing activities, squatting, walking up or downstairs, and running.

PFPS takes place whenever the muscles around the knee fail to keep the kneecap properly aligned, leading to abnormal lateral tracking of the patella.Overuse such as running and jumping sports, the trauma of kneecaps such as fracture, dislocation, or knee surgery may also predispose to PFPS.

Primary Outcome Measures

Name	Time	Method
Muscle strength assessment	after 12 weeks	assessed using a calibrated handheld dynamometer
Pain assessment	after 12 weeks	assessed by using a visual analog scale,10-cm VAS scale, with 0 indicating no pain and 10 for worst pain sensation

Secondary Outcome Measures

Name	Time	Method
Functional status	after 12 weeks	evaluated using the Arabic version of the Anterior Knee pain Questionnaire, The score ranges from 0 to 100, with 0 indicating complete functional limitation and 100 indicating no pain and no functional limitation.
health-related quality of life	after 12 weeks	assessed by using the self-report Pediatric Quality of Life Inventory, it includes 23 items distributed among 4 domains \[physical (8 items), emotional (5 items), social (5 items), and school functions (3 items)\]. Each item is rated on a 5- points scale (0 means never, and 4 means almost always). Items are transformed linearly to 0-100 scale (0 = 100, 1 = 75, 2 = 50, 3 = 25, and 4 = 0).
