摘要: Background. The flexion relaxation ratio (FRR) has been suggested as a measure of muscular performance in patients with low back pain (LBP). purpose this study was to investigate whether the FRR responsive acute LBP produced from delayed onset muscle soreness (DOMS) protocol. Methods. Fifty-one pain-free volunteers performed DOMS induce LBP. Current intensity, trunk range motion (ROM), and passive straight leg raise (SLR) were measured at baseline, 24 48 hours after DOMS. Participants categorized into groups based on reported current intensity. Changes FRR, ROM, SLR ROM examined using two-way repeated measures analysis variance. Results. Pain group not found have significant effect (F 1,29 = 0.054, P 0.818), nor there any interactions for changes FRR. had decreased compared minimal 1,38 7.21, 0.011), but no decreases 3.51, 0.057) over time. Interpretation. There differences intensity responsiveness might be limited origin.
