PERBANDINGAN ISOMETRIK QUADRICEPS DAN TENS DENGAN ISOMETRIK QUADRICEPS TERHADAP PENINGKATAN KEKUATAN OTOT PADA PASIEN CEDERA POST ANTERIOR CRUCIATE LIGAMENT (ACL) DI INF SPORT ENTERTAIMENT TAHUN 2025

The Anterior Cruciate Ligament (ACL) is a ligament located in the knee joint that is useful as a stabilizer that resists excessive forward movement of the tibia bone against the stable femur bone, or prevents excessive backward movement of the femur bone against the stable tibia bone. The prevalence of anterior cruciate ligament injury in Indonesia shows that knee injury in Indonesia
is the second highest disease after back pain, with a rate of 48 per 1000 patients with anterior cruciate ligament injury at 9%. Transcutaneous electrical nerve stimulation (TENS) is a physiotherapy intervention that works by blocking pain around the injured area using low-strength electricity flowing through electrodes attached to the pain area. Quadriceps exercise is an isometric exercise performed to increase quadriceps muscle activation. Quadriceps activation causes muscle
contraction and increases the density of capillaries and proteins in myofibrils. Muscle strength is the ability of a muscle to generate tension against a resistance. Muscle strength is the ability of a muscle or muscle group to perform work, by holding the weight it lifts.
