The Effect of Intelligent Exercise and Ergonomic Recommendations on Surgeon Musculoskeletal Discomfort

Pre-intervention The three months leading up to the trial start, all participants are introduced to up-to-date ergonomic recommendations. The ergonomic recommendations are informed by general ergonomic recommendations from the Danish Working Environment Authority, a systematic literature review on the effect of ergonomic interventions applied in the OR (REF and general ergonomic guidelines) and include two recommendations:

1. performing intra-operative microbreaks, and 2) knowledge of ergonomic work posture in the OR.

InterventionIntelligent Exercise app + ergonomic recommendations The duration of the ergonomic recommendations launch period is three months after which consenting participants will be randomized to either the control group or the intervention group. The control group will be encouraged to continue to apply the up-to-date ergonomic recommendations to their OR practice, this will act as usual care. In addition to the usual care, the intervention group will be prescribed individualized physical exercise training (IPET). The IPET is 50 min of tailored physical exercise per week, that is designed by an algorithm that uses the information (demographics, self-reported health, musculoskeletal pain and its location) the individual enters in the app (REF). The 50 min. Of total IPET per week can be performed in one session or divided into shorter sessions two-five sessions with the same effect (REF). The IPET will be delivered through the participants' mobile phone via a mobile application (app) that requires a unique code assigned for each participant. Each participant's exercise training program is different because it is composed of the input provided by the participant. Thus, as the participants experience progress (or deterioration) in their physical capacity during the study, the program will change accordingly.
