Effects of trunk Muscles Endurance, Hip Joint Muscular Strength, and Pelvic Alignment on Mild Low Back Pain

Objective: Low back pain easily becomes chronic and has a high recurrence rate. Therefore, it is most important to preventchronicity and reduce the risk of recurrence in the early stages of back pain or at the stage with mild pain. Therefore, this study was conducted to compare hip joint muscle strength, trunk muscle endurance, and pelvic alignment between subjects with mild lowback pain and subjects without back pain. Design: Crossed-sectional studyMethods: The study was conducted by recruiting 30 students in their twenties who are enrolled in K University in Gyeongsangnam-do,and classifying them into 15 patients with mild back pain and 15 patients with normal. The subjects who participated in theexperiment were measured for hip flexor and extensor muscle strength, trunk flexion and extension muscle endurance, and pelvicalignment. To measure hip joint muscle strength, biodex was used, and muscle endurance of the trunk was recorded at the endrange of the trunk flexion and extension. And pelvic alignment was measured using Formetric 4D. Results: There were no significant differences in hip joint muscle strength, pelvic alignment, and trunk extension muscleendurance. The retention time was found to be significantly shorter in the mild low back pain group than in the normal group fortrunk flexion muscle endurance. Conclusions: In the early stages of back pain or in the mild pain stage, training to increase muscle endurance of the flexor musclesmay be helpful.
