OBJECTIVES: To examine activation patterns of the myofascial chain in women
experiencing chronic low back pain (CLBP) and women without CLBP during a prone
hip extension (PHE) test. DESIGN: Cross-sectional. SETTING: Clinical research
laboratory. PARTICIPANTS: Fifteen women experiencing CLBP and 15 women without
CLBP. METHODS: Surface electromyographic recordings from the posterior oblique
sling during PHE. MAIN OUTCOME MEASUREMENTS: Two-sample t-tests were used to
compare demographic information and electromyographic signal amplitude of the
posterior oblique sling between groups. RESULTS: Women with CLBP exhibited
significantly increased normalized electromyographic signal amplitudes in the
contralateral latissimus dorsi (P = .01), contralateral elector spinae (P < .01),
ipsilateral elector spinae (P < .01), ipsilateral gluteus maximus (P = .03), and
ipsilateral biceps femoris (P = .02) compared with women without CLBP.
CONCLUSIONS: Women with CLBP had greater activity in the posterior oblique sling
muscles than did women without CLBP during PHE.
These findings suggest that an
alteration can be made in posterior oblique sling muscle activities during PHE in
women with CLBP.
