摘要

Background and Purposes: Low back pain is one of the most prevalent problems in modern living. Physical therapists often teach their patients abdominal muscle strengthening exercises and hamstring and low back stretching exercises as means of altering standing posture although little substantial evidence exists to support such treatment. The purpose of this study was to determine if abdominal muscle strength (ABDS), hamstrings length (HAML), and lumbar spine mobility (LMOB) had any relationship to the degrees of pelvic tilt (PTLT) and lumbar spine lordosis (LRDS) during relaxed standing. Method: Eighteen healthy subjects (9 females and 9 males) ranging in ages from 20 to 35 years were recruited on a volunteer basis for this study. Measurements of the ABDS, HAML, LMOB, PTLT, and LRDS were performed. The relationships between each pair of the measurement variables were determined using the Pearson product-moment correlation coefficients. Results: The results revealed a moderate positive correlation between ABDS and PTLT (r=0.51, p＜0.05), between ABDS and LRDS (r=0.51, p＜0.05), and between LMOB and LRDS (r=0.40, p＜0.05) No correlation was found either between HAML and PTLT (r=-0.23, p＞0.05) or between LMOB and PTLT (r=0.15, p＞0.05). No relationship was found between HAML and LRDS (r=-0.05, p＞0.05). Conclusions: The extents of pelvic anterior tilt and lumbar lordosis are moderately correlated with the abdominal muscle strength. The hamstring length had no influence on the extents of pelvic anterior tilt and lumbar lordosis. The lumbar spine mobility has no correlation with pelvic anterior tilt, but moderately related to the extent of lumbar lordosis although the relationship between them may be also attributed to the influence from other factors.
