Hip and Trunk Variables in University Students with and without Recurrent Low Back Pain

Area of Science:

• Orthopedics
• Sports Medicine
• Physical Therapy

Background:

• Low back pain (LBP) is a major cause of disability globally.
• Recurrent LBP (rLBP) involves multiple episodes of pain within a year.
• Previous research on LBP often overlooks rLBP, focusing on acute or chronic cases.

Purpose of the Study:

• To investigate differences in hip and trunk variables between university students with and without recurrent low back pain (rLBP).
• To compare range of motion (ROM) and strength metrics in relation to rLBP.

Main Methods:

• A cross-sectional study involving university students aged 18-35 with and without rLBP.
• Measurements included bilateral hip and trunk ROM using goniometers/tape measures.
• Hip extensor, abductor, and external rotator strength, plus single-leg bridge endurance, were assessed.

Main Results:

• Statistically significant differences were observed in right and left hip flexion and right hip extension and adduction ROM between groups.
• No significant differences were found in hip strength or endurance between students with and without rLBP.
• Observed ROM differences were statistically significant but not clinically meaningful.

Conclusions:

• The study identified statistically significant but clinically non-meaningful differences in hip ROM for individuals with rLBP.
• Hip strength and endurance may not be primary factors in the development or treatment of rLBP.
• Findings may inform testing and treatment strategies for patients and athletes experiencing rLBP.
