Abstract
Reneman MF, de Vries HJ, van den Hengel EJ, Brouwer S, van der Woude LH. Different
level, but a similar day pattern of physical activity in workers and sick-listed people
with chronic nonspecific musculoskeletal pain.
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 (Fchange=5.27, P=.024). In the mornings, group status significantly contributed to the variance in
mean activity counts (Fchange=5.32, P=.02). In afternoons (Fchange=3.29, P=.07) and evenings (Fchange=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' λ=.92, F14,104=.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.
