Gastrocnemius activation deficits and running biomechanics after anterior cruciate ligament reconstruction: the missing link?
The study investigates how gastrocnemius muscle activation deficits may influence running biomechanics after anterior cruciate ligament (ACL) reconstruction. Using synchronized BTS surface electromyography and biomechanical analysis, the authors examined neuromuscular patterns during running tasks. The results show that altered activation of the gastrocnemius can affect lower-limb biomechanics, potentially contributing to persistent functional deficits after surgery. These neuromuscular alterations may represent an important missing link between muscle function and movement mechanics during recovery. The findings highlight the value of integrated biomechanical and EMG assessment to better understand return-to-sport readiness and reinjury risk.
