Abstract
In young females, patellofemoral pain syndrome is commonly encountered in clinical setting. Proximal hip muscles strengthening exercises have been proposed effective in reducing pain and improving function. Identification of clinical examination variables as predictors to pain and dysfunction would offer therapists the chance to undertake clinical decisions and consequently improve treatment efficiency.
Objectives: This Predictive validity, diagnostic study was conducted to examine the effect of age, body mass index (BMI), duration of symptoms, and valgus of the knee on patients’ response (pain and function) to proximal control training.
Materials and methods: Fifty females participants with patellofemoral pain (PFP) recruited from Ain-Shams University Hospital with mean age of 25 years, received proximal control exercises (transversus abdominis and multifidus activation, hip extensor, abductor and external rotator strengthening). These exercises were done 2 times/week for 4 weeks. Participants were assessed for knee pain by Visual analogue scale (VAS), knee function by Kujala questionnaire, and dynamic knee valgus (DKV) using Kinovea Computer programme (KCP) V.0.8.15 video analysis.
Results: Among the four tested predictors, only DKV (≥21.5 degree) can predict improvement in knee pain intensity with proximal control exercises, with area under curve, sensitivity, and specificity are 0.72, 0.6, and 0.6, respectively. There are no predictors of improvement in knee function; Age was found to be a predictor of success in hip abductor strength and duration of symptoms as predictor of success in hip external rotators strength with proximal control exercises in patellofemoral pain syndrome female individuals, with no specific cutoff points.
Conclusions: Proximal control exercises can improve knee pain and function in females with PFPS if DKV ≥ 21.5 degree, Proximal control exercises can improve hip strength in female with PFPS with no specific cutoff points for the significant predictors found (age and symptoms duration).
