Effect of Contralateral NMES on Quadriceps Activation After ACL Injury or Surgery
Sponsor: Schulthess Klinik
Summary
A major complication after cruciate ligament injury and surgery is arthrogenic muscle inhibition of the quadriceps, which is characterised by a deficit in voluntary muscle activation in the affected leg. This can hinder rehabilitation processes, lead to impaired knee function, and negatively impact the patients' quality of life. The primary objective of this study is to assess whether voluntary quadriceps activation on the injured side is facilitated by the concomitant application of neuromuscular electrical stimulation (NMES) on the contralateral quadriceps.

Neuromuscular Electrical Stimulation
Studies in healthy individuals have demonstrated that NMES applied to the quadriceps of one limb induces short-term increases in strength and neural drive in the contralateral homologous muscle. Since these effects have only been observed in healthy individuals, it is essential to investigate whether similar responses occur in ACL patients.
