PMID 40335002WHAT IT FOUND
Older adults with chronic low back pain and hip involvement reported worse pain quality and lower self-efficacy than those with no hip impairments.
This subgroup also had less trunk flexibility and endurance. Screening for hip symptoms may help identify patients at higher risk for disability.
Key findings
01Participants with hip weakness and pain (WS subgroup) had significantly worse pain quality, greater pain dispersion, and the lowest self-efficacy scores compared to other subgroups.
02Greater hip involvement was associated with decreased trunk active range of motion, particularly in thoracolumbar flexion, and reduced trunk extensor endurance.
03All subgroups showed lower multifidi muscle activity compared to healthy older adults, with the hip weakness subgroup showing the lowest activity.

What it does not show
The cross-sectional design cannot establish causality; it only shows associations between hip subgroups and other characteristics. Participants were not care-seeking and had mild-to-moderate pain, so findings may not generalize to more disabled or treatment-seeking populations. The Modified Biering-Sorensen test for endurance can be influenced by motivation and pain, not just muscle capacity. Subgroup assignment was based on hip strength and symptoms, but differences in other areas (pain, psychology) were not used to create the groups, which may limit the precision of the classification for treatment targeting.
Declared interests
None declared in the provided text, though the study was supported by N.I.H. Extramural funding.
The easy way to misread this
Do not assume that hip impairment causes the worse pain or psychological profiles. The study is cross-sectional and only shows an association between hip subgroups and these characteristics. Also, do not apply these findings to patients with severe disability or those actively seeking care, as the study population had mild-to-moderate pain and was not care-seeking.
