Summary

An imbalance in the activation and onset time of the vastus medialis oblique (VMO) and vastus lateralis (VL) muscles may be one of the primary causes of PFPS. Several studies have discussed various exercise methods believed to selectively contract the (VMO) muscle for treating patellofemoral pain syndrome. VMO activity is higher during static closed-chain tasks combined with hip adduction, indicating that performing hip adduction exercises may selectively strengthen the VMO muscle.

Detailed description

Patellofemoral pain syndrome (PFPS) poses challenges in motor control and pain management, especially regarding balanced muscle activation of the vastus medialis oblique (VMO) and vastus lateralis (VL). This study introduces a home-based PFPS rehabilitation approach involving a squat exercise program with hip adduction, examining its effects on motor control and clinical outcomes. Thirty PFPS participants were randomly assigned to conventional squatting (SQU) or squatting with hip adduction (SQU-HA) groups. Participants performed exercises five days a week for 8 weeks, with pre- and post-assessments capturing clinical measures and motor control indicators using electromyography (EMG). This home-based program, integrating hip adduction into squats, enhances motor control, reduces knee stress, and improves daily function, ensuring continued care post-pandemic.

Interventions

Type	Name	Description
OTHER	squatting with hip adduction (SQU-HA) group	The intervention comprised three sets of 15 repetitions with resting 5-min between sets, followed by IT band stretching for five repetitions. Each participant performed the respective exercise 5 days a week, with 2 days of rest, for 8 weeks.
