Correlation Study Between the Classification of Arthrogenic Motor Inhibition (AMI) and Clinical Assessment After ACL Rupture

Condition(s) studied

Investigational drug(s) / intervention(s)

Clinical testing: Intervention includes : * Surface EMG to measure inhibition of the VM and the rectus femoris (RF) on the injured and non-injured sides during attempts at voluntary contractions of the knee extensor muscles. * Myotonometry to measure the stiffness of the semimembranosus and biceps femoris (long head) on the injured and non-injured sides under resting conditions

Study summary

The goal of this interventional study is to measure medial vastus inhibition and associate it with AMI classification in patients with ACL rupture. The main question it aims to answer is:

Is there a correlation between AMI classification and clinical assessment after ACL rupture ? Participants will undergo surface EMG and Myotonometry.

Eligibility

Primary outcome measure(s)

• Muscle Surface EMG and AMI correlation — From enrollment to Day 30
  Electrical signal amplitude, expressed in mV, is evaluated at the level of the VM. This electrical signal amplitude is correlated with the level of muscle activation. It is measured with a surface EMG, which measures the activation of the VM during a voluntary attempt to contract the knee extensors. The ratio: Amplitude of the electrical signal from the injured side of the VM / Amplitude of the electrical signal from the non-injured side of the VM is used to determine the inhibition of the VM. AMI is assessed using the Sonnery-Cottet classification (Sonnery-Cottet et al, 2022)
