Quadriceps Force Fluctuation During Maximal Isometric Contraction is Altered in ACL Injury and is Associated with Lower Limb Functional Performance: A Cross-Sectional Study with Athletes
SUMMARY Objective. This study aims to investigate the effects of ACL injury on force fluctuation measures (stability and complexity) of the quadriceps muscle, and how these measures relate to functional performance. Methods. Forty-two athletes (14 females) with unilateral ACL injury were assessed. Quadriceps maximal isometric contraction was performed for both limbs before any surgical intervention. … Continued
