Abstract
Purpose: To investigate between-limb gait and muscle strength asymmetry in patellofemoral pain syndrome (PFPS) subjects and controls.
Methods: Three-dimensional hip, knee, and ankle joint kinematics were collected during treadmill running. Maximum voluntary isometric contractions of the hip musculature were collected using a force dynamometer. PFPS subjects completed a 6-week strengthening program. Discrete variable asymmetry was calculated using analysis of variance and waveform kinematic asymmetry was calculated using coefficients of multiple correlation and root mean square error.
Results: PFPS exhibited between-limb asymmetry of hip and knee transverse plane waveform kinematics, while controls exhibited asymmetry of hip frontal plane waveform kinematics. PFPS subjects exhibited decreased hip transverse plane and increased knee transverse plane waveform kinematic asymmetry following rehabilitation.
Conclusion: PFPS subjects demonstrate a different pattern of gait asymmetry than controls. Increases in hip muscle strength results in between-limb asymmetry of PFPS subjects to more closely resemble that of healthy controls.
