OBJECTIVE: To investigate whether physical activity (PA) levels and day patterns
of sick-listed workers with chronic nonspecific musculoskeletal pain (CMP)
admitted for multidisciplinary rehabilitation are different from those of workers
with CMP. DESIGN: Cross-sectional. SETTING: Outpatient rehabilitation center and
general community. PARTICIPANTS: A convenience sample of sick-listed patients
with CMP (n=27) referred for multidisciplinary pain rehabilitation, and a
volunteer sample of workers with CMP (n=107; <5% sick leave in year before
participation). INTERVENTION: Participants wore an accelerometer for 5 to 7
consecutive days. MAIN OUTCOME MEASURE: PA, expressed as activity counts.
All analyses were corrected for confounders. RESULTS: PA levels of workers with CMP
were higher than those of sick-listed patients (P=.01).
After correction for
confounders, work status explained 3.5% of the variance observed in activity
counts (F(change)=5.27, P=.024). In the mornings, group status significantly
contributed to the variance in mean activity counts (F(change)=5.32, P=.02). In
afternoons (F(change)=3.29, P=.07) and evenings (F(change)=2.41, P=.12), the
effect of group status on PA level was nonsignificant. No significant interaction
was observed between time and group status (Wilks' lambda=.92, F(14,104)=.66,
P=.80). CONCLUSIONS: Workers with CMP have a higher PA level compared with
sick-listed patients. The PA day pattern did not differ significantly between the
2 groups.
