Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Minimally invasive surgeons have a prevalence of work-related musculoskeletal complaints of up to 86% due to the exposure to static loading, awkward postures, work pressure, and patient's wellbeing. Researchers have developed postural interventions to counteract the prevalence of musculoskeletal complaints and disorders, such as robot-assisted surgeries, arm-support systems, and rotatable handle pieces. An alternative intervention is to implement work breaks during the surgeries, which has shown to give promising results including that surgery duration does not prolong.

The aim of the current study is to simulate 90-min laparoscopic surgery activities in the laboratory and compare two intervention situations with the control situation. The control situation is without work breaks. The two intervention situations include 2.5-min breaks provided two times, i.e. after every 30-min work period, which are passive (rest) or active (targeted mobilization exercises). The assessment is based on changes in muscular activity on the back and upper extremities, back and upper extremity postures, feelings of discomfort, and work performance.

Blinding Strategy

NONE

The study is not blinded, because the subject(s) will know which of the three experimental conditions they are exposed to (control without breaks; intervention with passive or active breaks). The same applies to the experimenter(s).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

No breaks

Subjects will simulate a 90-min laparoscopic activities in the laboratory.

Group Type NO_INTERVENTION

No interventions assigned to this group

Passive breaks

Subjects will simulate a 90-min laparoscopic activities in the laboratory, and after 30 and 60 min of work, they will be provided a 2.5-min break during which they can have a rest.

Group Type EXPERIMENTAL

Work break schedule

Intervention Type BEHAVIORAL

Participants will receive 2.5-min breaks during a 90-min simulated laparoscopic surgery in the laboratory. The breaks will be either passive (simple rest) or active (selected mobilization exercises).

Active breaks

Subjects will simulate a 90-min laparoscopic activities in the laboratory, and after 30 and 60 min of work, they will be provided a 2.5-min break during which they will be performing some mobilisation exercises for the back, shoulder, and neck.
