Summary

Study Purpose: The purpose of this study is to investigate the effect of adding core muscle strengthening exercises to a hip- and knee-focused exercise program on pain intensity, dynamic knee valgus (DKV), and functional outcomes in female patients with patellofemoral pain syndrome (PFPS). Research Question: Does adding core muscle strengthening exercises to a hip- and knee-focused exercise program have an effect on pain intensity, dynamic knee valgus (DKV), and functional outcomes in female patients with PFPS?

Detailed description

Detailed Description: Therefore, the current study aims to investigate the effect of adding core muscle strengthening exercises to a hip- and knee-focused exercise program on pain intensity, dynamic knee valgus (DKV), and functional outcomes in female patients with patellofemoral pain syndrome (PFPS). The findings of this study may provide a more effective rehabilitation program for female patients with PFPS, support the use of validated outcome measures in clinical practice, and improve symptom management during activities of daily living and functional recovery within a shorter period of time. This combined approach may be more efficient than the conventional hip- and knee-focused exercise program alone. Systematic assessment and monitoring of patient outcomes are recommended to guide clinical decision-making. Study Delimitations: This study will be delimited to: Female patients clinically diagnosed with patellofemoral pain syndrome (PFPS). Thirty-six participants aged 19-35 years with body mass index (BMI) up to 25 kg/m². Assessment procedures including Visual Analogue Scale (VAS) for knee pain, dynamic knee valgus (DKV) measured using Kinovea software, and the Knee Outcome Survey-Activities of Daily Living Scale (KOS-ADLS) for knee function. Treatment procedures: Group A (control group): hip- and knee-focused exercise program. Group B (study group): hip- and knee-focused exercise program in addition to core muscle stability exercises.

Interventions

Type	Name	Description
BEHAVIORAL	Core Muscle Stability Exercise Program	core muscle training exercises, including the front plank, side plank, and dead bug exercises
BEHAVIORAL	hip and knee-focused exercise program	Open kinetic chain exercises including side-lying hip abduction, hip external rotation (clamshell), prone hip extension, short arc quadriceps, and straight leg raises (Khayambashi et al., 2012) ( Dolak et al., 2011). 1. Closed kinetic chain exercises including mini wall squats and terminal knee extensions (Hott et al., 2020). 2. Flexibility exercises targeting tight lower extremity soft tissues, including a seated hamstring stretch, standing quadriceps stretch, and standing wall stretch for the gastrocnemius
