Objective: The purpose of this study was to examine the relationships between low back pain (LBP) and trunk endurance (TE) in a United States Veteran population.
Methods: Data were collected from the Veterans Affairs Palo Alto Healthcare System electronic health records (01/2019-12/2019) to identify adults aged 18-89 years presenting with nonsurgical LBP for a chiropractic consultation. Coefficient estimates, standard error, and P-values were calculated from multivariable linear regression for primary (LBP severity) and secondary (functional disability) outcomes, controlling for age, sex, and body composition.
Results: A total of 85 patients (mean age 53.6 years) were included. Trunk endurance was significantly associated with LBP severity (β: -0.042, P < .001) and Oswestry disability index (ODI) scores (β: -0.334, P < .001) suggesting that participants with greater TE (ie, longer prone bridge (plank) test time) had lower LBP severity and lower functional disability than those with poorer TE.
Conclusion: In this sample of Veterans, higher LBP severity and greater functional disability (ODI scores) were associated with reduced TE. Body mass index did not significantly influence these relationships.
