Musculoskeletal symptoms The intervention did not result in statistically significant effects on musculoskeletal symptoms (table 4). Although for back symptoms at 6 and 12 months follow-up (OR 0.69, 95%CI: 0.361.36, and 0.76, 95%CI: 0.38-1.52, respectively) and lower extremity symptoms at 12 months (OR 0.61, 95%CI: 0.32-1.16) the odds ratios were in favour of the intervention group, differences reached no statistical significance. Sickness absence Table 5 shows mean days of sickness absence in the past 6 months and table 3 presents the course of sickness absence for the study group, dichotomized into no or short term, and longterm sickness absence. Directly following the intervention, the 6-month prevalence of longterm sickness absence was lower in the intervention group than in the control group. At 12 months sickness absence was slightly higher in the intervention group compared to the control group. However, at both 6 and 12 months the between group differences were not statistically significant.
