MUSCULOSKELETAL DISORDER
In the MI group, 53% received two MI sessions, 7% one session, and 40% no sessions. For the active control group, the numbers were 41%, 19%, and 40% respectively. Reasons for not receiving the interventions are described in figure 1 when known, however, most are unknown due to participants not giving a reason (due to research ethics not required). There was no clear pattern in compliance increasing or decreasing over time. Participants who received two MI sessions were more likely to be female (67% versus 62%) and have higher education (66% versus 56%) compared to those who received no sessions. The average age was similar between the two groups (mean 44 versus 43). Musculoskeletal disorders dominated for both those receiving two MI sessions and no MI sessions (41% and 43%), while psychological diagnoses were more common for those receiving two sessions than those receiving no MI sessions (35% versus 27%). Those who received two MI sessions had more sick leave during follow-up: median 103 (IQR 49–161) days compared to those with no sessions 45 (IQR 20–112) days.
