Effect of Fatigue on Quadriceps Force Control After ACL Reconstruction – Uninjured Control Group
While we know thigh muscles are weakened after ACL reconstruction (ACLR), less is known about how well the thigh muscles can control their voluntary effort in a state of fatigue. Our goal is to better understand how ACLR affects thigh muscle force control and the associated physiology by comparing these factors between individuals with a history of ACLR and those with no previous lower extremity surgery (e.g. uninjured control group).
Participation involves a single, 1.5 hour session consisting of ultrasound imaging and strength and force control assessment of the thigh muscles.
Inclusion Qualifications:
- Age of 18-35
- No history of lower extremity surgery ever
- No history of lower extremity injury (defined as seeking medical attention) within the last 2 years
Exclusion Qualifications:
You may not participate in this research opportunity if any of the following applies to you:- Current infection on lower limb
- Known or diagnosed muscular abnormalities
- History of cardiopulmonary disorder
- Known pregnancy
