Comparing the Hip and Lumbar Joint Range of Motion in Patients With Lower Lumbar Disc Herniation and Healthy Subjects

One possible factor contributing to low back pain is hip range of motion (ROM). However, there is inconstancy in published studies, which may be due to the heterogeneity of patients. Therefore, the present study focuses on the relationship between hip ROM and lower lumbar disc herniation (LLDH).

A cross-sectional study involved 52 participants between 18 and 65 years old. Two digital inclinometers were utilized to measure the ROM of the lumbar and hip joints in all study participants. For each outcome, 2 measurements were conducted, and the mean of the 2 measurements was utilized for analysis. The level of statistical significance was established at P ≤ .05.

The difference in all ROM between the 2 groups is significant except for dominant hip flexion (P < .05). Lumbar flexion was reduced in LLDH compared with healthy individuals (P = .003). The findings manifested a significant correlation between right lumbar rotation and nondominant hip abduction (P = .05, R = .388) and between left lumbar lateral bending and nondominant hip flexion (P = .008, R = .510).

Patients with LLDH have reduced hip ROM and lumbar flexion compared with healthy individuals. The study showed correlations between hip and lumbar ROM and emphasized the significance of evaluating hip ROM in LLDH for assessment and treatment planning.
