Muscle Weakness After Anterior Cruciate Ligament Reconstruction | Contralateral Strength-training After Anterior Cruciate Ligament (ACL) Reconstruction

Muscle Weakness After Anterior Cruciate Ligament Reconstruction research study

What is the primary objective of this study?

The main aims of the study are (1) to examine the impact of contralateral strength training on the quadriceps muscle function after ACL surgery and (2) to compare the magnitude of cross-education induced by NMES versus eccentric strength training.

Who is eligible to participate?

Inclusion Criteria: - patients scheduled for ACL reconstruction surgery Exclusion Criteria: - Concomitant lower limb injury or disorder - previous lower extremity open surgery on the contralateral lower limb - cardiac disease - pregnancy

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Muscle Weakness After Anterior Cruciate Ligament Reconstruction

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Behavioral:Neuromuscular electrical stimulation

Behavioral:eccentric training

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

NMESneuromuscular electrical stimulation (NMES) of the quadriceps muscle with Kneehab

eccentric trainingunilateral eccentric resistance exercises

sham NMESneuromuscular electrical stimulation of the quadriceps muscle with intensity which causes no visible contraction or displacement of the leg (activation below motor threshold)
