The Influence of Clinical, Functional, and Psychosocial Factors on Walking Time in Individuals With Chronic Low Back Pain

Daily Pain Severity but Not Vertebral Fractures Is Associated With Lower Physical Activity in Postmenopausal Women With Back Pain

Back pain lifetime incidence is 60%-70%, while 12%-20% of older women have vertebral fractures (VFs), often with back pain. We aimed to provide objective evidence, currently lacking, regarding whether back pain and VFs affect physical activity (PA). We recruited 69 women with recent back pain (age 74.5 ± 5.4 years). Low- (0.5 < g < 1.0), medium- (1.0 ≤ g < 1.5), and high-impact (g ≥ 1.5) PA and walking time were measured (100 Hz for 7 days, hip-worn accelerometer). Linear mixed-effects models assessed associations between self-reported pain and PA, and group differences (VFs from spine radiographs/no-VF) in PA. Higher daily pain was associated with reduced low (β = -0.12, 95% confidence interval, [-0.22, -0.03], p = .013) and medium-impact PA (β = -0.11, 95% confidence interval, [-0.21, -0.01], p = .041), but not high-impact PA or walking time (p > .11). VFs were not associated with PA (all p > .2). Higher daily pain levels but not VFs were associated with reduced low- and medium-impact PA, which could increase sarcopenia and falls risk in older women with back pain.

Avoidance-Endurance Model in Older Black Men with Low Back Pain: Exploring Relationships

OBJECTIVE

The objective of the study was to investigate functional performance and pain intensity outcomes for associations with negative cognitive orientations, avoidance behaviors, and fear of pain in older Black men with low back pain (LBP).

METHODS

Sixty Black men aged 60 and older (70 years[Formula: see text]) with LBP completed the Short Physical Performance Battery (SPPB), the 400-m walk test, and subjective measures of avoidance behaviors, back performance, pain intensity, and pain catastrophizing (i.e., rumination, magnification, and helplessness). Multiple regression models were used to examine associations.

RESULTS

Higher helplessness scores were associated with worse back performance (ß = 0.55, p = 0.02), slower walking speed (ß = 0.30, p = 0.02), and higher average pain intensity (ß = 0.22, [Formula: see text] p = 0.03). Higher rumination scores were associated with better back performance (ß =  - 0.36, p = 0.04). Avoidance behaviors, fear of pain, and magnification were not significantly associated with any of the variables included in the tested models.

CONCLUSION

Negative cognitive internalization is associated with limitations in functional performance in older Black men with LBP. Additional research is needed to further examine the cognitive orientations for understanding experienced pain and function in this population. Such research may inform the development of interventions for improving functional performance outcomes of older Black men with LBP.
