OBJECTIVE: To determine whether a relationship exists between sagittal plane hip
range of motion loss and sagittal plane lumbar Movement System Impairment (MSI)
categories in patients with low back pain (LBP). DESIGN: Correlational study.
SETTING: University outpatient physical therapy clinic. PARTICIPANTS: Subjects
(N=40) with LBP. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES:
Classification into a flexion- or extension-based lumbar MSI category, and
bilateral passive hip flexion and extension range of motion testing. Using
predefined criteria, subjects in each MSI category were subclassified into 1 of 3
hip stiffness categories: (1) a considerable loss of either flexion or extension
(pattern A); (2) a considerable loss of both flexion and extension (pattern B);
or (3) minimally limited flexion or extension (pattern C).
RESULTS: Pattern A
occurred in 23 (57.5%) subjects, with the primary direction of hip motion loss
agreeing with the MSI category 78.3% of the time (phi=.56; P=.007). Pattern B
occurred in 10 (25%) subjects, with the primary direction of hip motion loss
agreeing with the MSI category 70% of the time (phi=.47; P=.197). Pattern C
occurred in 7 (17.5%) subjects, with the primary direction of hip motion
limitation agreeing with the MSI category 42.9% of the time (phi=-.40; P=.290).
CONCLUSIONS: Considerable unidirectional hip motion loss in the sagittal plane
was a common finding among subjects with LBP and yielded a strong positive
relationship with the same direction MSI category. These results may inform
future studies investigating whether treatment of hip stiffness patterns could
improve outcomes in LBP management.
