PERBANDINGAN KEKUATAN DAN FLEKSIBILITAS OTOT HAMSTRING PADA PASIEN DENGAN LOW BACK PAIN DAN PASIEN TANPA LOW BACK PAIN DI RSUD DR SOETOMO

Hamstring muscle is thought to be one of important cause of low back pain because of its anatomical and physiological properties are related to lumbo-pelvical rhytm and it works int two different joints. Any tightness in this muscle will affect the function of those two joints and the lumbo-pelvical rhytm. The research was designed to compare differences in strength, endurance, power, and flexibility of hamstring muscle in patients with low back pain and patients without low back pain. The study involved 12 recruited patients with LBP and 12 patients without LBP. All come from out-clinic patients of Medical Rehabilitation Departement Dr. Soetomo General Hospital between April – October 2017. The method used in this research depends on each parameters. Muscle strength and endurance were measured using Isokinetic-CybexNorm™ Testing and Rehabilitation System. Muscle power was measured using vertical jump test and muscle flexibility was measured using sit-and-reach test. Datas were analyzed by using independent two tailed T-test at α = 0,05 Patients with LBP shows a significantly different result on each of parameter (muscle strength, muscle endurance, muscle power, and muscle flexibility) compared to patients without LBP (p < 0,05). From then on, it can be concluded that there is a significant different in muscle strength, muscle endurance, muscle power, and muscle flexibility between patients with LBP and without LBP
