Effect of Posterior Pelvic Tilt Taping on Abdominal Muscle Thickness and Lumbar Lordosis in Individuals with Chronic Low Back Pain and Hyperlordosis: A Single-Group, Repeated-Measures Trial.

Objective: The purpose of this study was to investigate the effect of posterior pelvic tilt taping (PPTT) on lumbar lordosis, pain, disability, and abdominal muscle thickness in individuals with nonspecific chronic low back pain with hyperlordosis. Methods: A prospective, single-group, repeated-measures design was conducted with 31 individuals with nonspecific chronic low back pain (16 men, 15 women) with hyperlordosis (mean +/- SD = 59.3 degrees +/- 2.9 degrees). Participants' mean age, pain, disability, and lumbar lordosis were, respectively, 35.7 +/- 9.9 years, 5.1 +/- 1.3, 26.8 +/- 11.5, and 59.3 degrees +/- 2.9 degrees. The thickness of the abdominal muscles on both sides was measured in the crook lying position by ultrasound imaging. PPTT was performed on both sides. Pain intensity, functional disability, lumbar lordosis angle, and abdominal muscle thickness were measured before PPTT (W0), 1 week after PPTT (W1), and 1 week after PPTT removal (W2). Results: Analysis revealed significant reductions in lumbar lordosis, pain, and disability, and increased abdominal muscle thickness, at W1 and W2 compared with W0 (P < .001). There were no significant differences in lumbar lordosis or abdominal muscle thickness between W1 and W2. Conclusion: The current study showed in a small group of participants that 1 week of PPTT may improve lumbar lordosis, pain, disability, and abdominal muscle thickness in individuals with nonspecific chronic low back pain with hyperlordosis.
