Effect of Pain and Hip Muscle Strength and Flexibility on Functional Status of Females with Patellofemoral Pain Syndrome

The objective of this study was to determine the effect of pain and hip muscle strength and flexibility on functional status of females with the Patellofemoral pain syndrome. This cross sectional study was conducted at Chaudhary Mohammad Akram hospital, Sports and Spine center and Ehsan rehabilitation center on a sample of 40 females. Non-probability, purposive sampling was used. Kujala score was used to measure the functional status of females with PFPS. Pain was measured through Visual analogue scale (VAS) and hip muscle strength and flexibility were tested through manual muscle testing (MMT) and special tests respectively. Linear regression was used to assess the effect of pain, muscle strength and flexibility on functional status using Kujala score as dependent variable. Pain explained 37.6 % variation in the functional status of females with patellofemoral pain syndrome. Prediction of the functional status of females with PFPS by pain along with gluteus maximus strength was statistically significant (p=.000). The study concludes that pain in unilateral squat and strength of hip extensors are better predictors of functional status in females with patellofemoral pain syndrome. However, Hip muscle flexibility is not a good predictor of functional status.
