Biomechanical Evaluation of Preoperative Rehabilitation in Patients of Anterior Cruciate Ligament Injury.

ABSTRACT: OBJECTIVES:To investigate the biomechanical characteristics of patients with anterior cruciate ligament (ACL) injury by gait analysis, surface electromyography (SEMG), and proprioception test, and provide rehabilitation suggestions according to the results. METHODS:In this retrospective cohort study, 90 adults with unilateral ACL injury, ranging in age from 19 to 45?years (66 men and 24 women, average age: 30.03?±?7.91) were recruited for this study form May 2018 to July 2019. They were divided into three groups according to the time after the injury: group A (3-week to 1.5-month), group B (1.5-month to 1?year), and group C (more than 1?year). The SEMG signals were collected from the bilateral rectus femoris (RF), vastus medialis (VM), and vastus lateralis (VL) and the root mean square (RMS) were used to assess muscular activity. SEMG were used to analyze muscles function, gait analysis was used to evaluate the walking stability, balance and location assessment were used to analyze the proprioception. RESULTS:Through the comparison between bilateral limbs, all muscles strength shown decreased (RF: 239.94?± 129.70 vs 364.81?±?148.98, P = 0.001; VM: 298.88?±?175.41 vs 515.79?±?272.49, P = 0.001; VL:389.54?± 157.97 vs 594.28?±?220.31, P
