Lower extremity muscle patterns and frontal plane biomechanics are altered in the contralateral knee of adults with osteoarthritis compared to asymptomatic adults

This study used EMG data to analyze biomechanics in those affected by knee osteoarthritis (OA) in the Journal of Electromyography and Kinesiology, Volume 75, April 2024. By: Sarah Remedios, Derek Rutherford

Surface electromyography was used to compare knee joint muscle activity during gait between the contralateral limb of individuals with knee osteoarthritis (OA) and an asymptomatic older adult group. The findings highlight the importance of exploring the implications of contralateral knee function of individuals with moderate knee OA, particularly considering the altered antagonist muscle activations, and heightened frontal plane moments.
