简要总结
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.
详细描述
The primary objective of this study is to assess whether injured-side voluntary quadriceps activation before and after ACL surgery is facilitated by the concomitant application of NMES on the contralateral quadriceps (uninjured side), in comparison to a control (CTRL) condition that does not involve any contralateral activity (passive rest) and to a voluntary (VOL) condition that involves a maximal voluntary contraction of the contralateral quadriceps.

结局指标
主要结局
EMG activity
时间窗: Data will be collected at two time points: after ACL injury (within two weeks prior to surgery) and following ACL reconstruction (within three days post-surgery).
EMG data will be recorded from the vastus medialis, vastus lateralis and rectus femoris muscles.
