To investigate the prevalence of and factors associated with dysfunctional low back pain (LBP) in patients with rheumatoid arthritis (RA). ⋯ The factors associated with dysfunctional LBP in patients with RA were more vertebral fractures, higher DAS-28CRP, vertebral endplate and/or facet erosion, higher BMI, longer disease duration, greater PT, older onset age, greater SVA, and less MTX use. Strictly controlling patients' body weight and disease activity with MTX and avoiding spinopelvic malalignment through vertebral fracture prevention are important.

Altered spine kinematics are a common in people with LBP. This may be especially true for populations such as dancers, who are required to perform repetitive movements of the spine, although this remains unclear. ⋯ Altered transverse plane spine kinematics were evident in dancers with recent LBP for select segments and tasks. This may reflect a protective movement strategy. However, as the effect sizes of observed differences were moderate, and the total number of differences between groups was small, collectively, it seems only subtle differences in spine kinematics differentiate dancers with LBP to dancers without.

The purpose of this pilot study was to assess the feasibility and usability of an ecological momentary assessment smartphone application. The app collected real-time data on chronic low back pain and time-contingent ecological momentary assessment surveys during a 4-week auricular point acupressure intervention, and on the consistency between recalled and momentary clinical measures. Eighteen participants received auricular point acupressure treatment weekly for 4 weeks. ⋯ Self-reported average pain interference with daily activities showed a similar result. Spearman rank correlation coefficients were greater than +0.70; P < .01 for the associations among recalled and momentary measurements. In conclusion, the study demonstrated promising adherence rates and supported the usability and feasibility of using an ecological momentary assessment application on a smartphone to collect real-time data on chronic lower back pain, which eliminated recall bias.
