Effects Of Ultrasound And Isometric Knee Exercise On Post-Recovery Anterior Cruciate Ligament Injury To Increase Quadrisep Muscle Strength

Abstract

This study aims to determine the effectiveness of the physiotherapy approach using ultrasound and isometric knee exercise in post-recovery anterior cruciate ligament injury to increase quadriceps muscle strength. More than 2,000,000 cases of anterior cruciate ligament (ACL) occur worldwide. Anterior cruciate ligament injury is the most common type of ligament injury and in this condition, the knee joint requires a period of rest and recovery. Quadrisep muscle weakness often occurs after an anterior cruciate ligament (ACL) knee injury resulting in prolonged disability and an increased risk of re-injury and osteoarthritis after surgery. Injuries are classified into direct contact, indirect contact, and non-contact, where non-contact injuries are the most common. This study used pre and post-experimental methods with a sample of 10 people, and evaluation measurements were carried out using manual muscle testing. in this treatment group using the normality test using the Shapiro-Wilk test on all pre-test and post-test variables, a value of P<0.05 was obtained, which means that the data is abnormally distributed. then the treatment group data obtained the results of the normality value test before P>0.000 which means P<0.05 and the value after the intervention P<0.008 which means P>0.05, then the hypothetical results using the paired samples t-test of this study obtained a value of P = 0.004 (P<0.05) with an average value of 2,300±.21884 which means the intervention of ultrasound and isometric knee exercise in the condition of anterior cruciate ligament injury after significant in increasing quadrisep muscle strength.
