Study designs: Randomized Controlled Trial, Clinical Trial
Abstract: Chronic low back pain (LBP) is a common condition among desk-bound employees due to prolonged sitting and is often associated with impaired sleep quality. This study examined whether an intervention focused on reducing sedentary behavior resulted in improved sleep quality in adults with chronic LBP. 24 adults (49.7 ± 10.8 y, 75% female) with chronic LBP, Oswestry Disability Index (ODI) >10 %, and desk-bound jobs with ≥20 h/wk of sitting completed the study. Participants were randomized to one of two 6-mo treatments: (1) a no-treatment control condition (n=12) or (2) an intervention focused on reducing prolonged sitting (n=12). The intervention included behavioral counseling (initial in-person visit, monthly telephone calls), a sit-stand desk attachment with a goal to stand for 2 h each day, and an activity-prompting device that vibrated after 30 min of inactivity. At baseline and 6 mo, sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI), LBP was measured using the ODI, and sitting time (work and overall) was assessed by self-report. Paired t-tests and analysis of covariance examined within- and between-condition changes, respectively, in PSQI, ODI, and sitting time; Pearson correlations evaluated associations between changes in sitting time, pain, and sleep. At baseline, ODI was 24.4 ± 10.4%, daily sitting time was 6.9 ± 1.1 h (work) and 10.2 ± 1.9 h (overall), and PSQI score was 7.8 ± 3.7. Both conditions reduced overall and work-based sitting time over 6 mo (P<.01), with a greater between-condition reduction in sitting time in the intervention (P≤.04). ODI improved from baseline within the intervention condition (P=.002), and tended to improve more than control (P=.09). Over 6 mo, sleep quality tended to improve with the intervention (P=.08); however, the between-group change was nonsignificant (P=.49). In the full sample, 6-mo reductions in sedentary time were correlated with increased total sleep time (TST; r≥-.30), and ODI reduction was correlated with increased TST (r=-.30) and reduced PSQI score (r=.42). These pilot data provide preliminary evidence that reducing sitting time may improve sleep quality through reduced pain among adults with chronic LBP. Larger trials with more comprehensive sleep assessments are needed to substantiate these findings. None
