Activation Failure of Knee Extensors After Anterior Cruciate Ligament Rupture Depending on the Contraction Mode
Sponsor: La Tour Hospital
Summary
The primary objective of the study is to evaluate the impact of ACL injury and ACL reconstruction on voluntary activation during maximal voluntary contraction (measured by neurophysiological parameters) according to the contraction mode. The goal is to provide elements of knowledge to clinicians about the mechanisms of the activation failure depending on contraction mode, but also the resulting adapted clinical recommendations for conducting rehabilitation, and particularly for the use of different contraction modes. The main hypothesis is that activation failure is not equal according to the contraction mode during maximal voluntary contractions and neurophysiological parameters will be decreased in comparison with non-injured subjects. Secondary objectives are: * To analyze the evolution of neurophysiological parameters between sessions interspaced by several months according to the contraction mode. * To observe this time evolution depending on the treatment strategy chosen: rehabilitation or surgery plus rehabilitation.
