Reducing Shoulder Complaints in Employees With High Occupational Shoulder Exposures

Introduction:

Shoulder complaints prevail in the working age population and constitute a common cause of contacts with general practitioners. In occupations with high mechanical shoulder exposures, these complaints are especially frequent. Persons with high occupational mechanical shoulder exposures and shoulder complaints seem an obvious target group for secondary prevention efforts, and more research on interventions targeting shoulder complaints in occupations with high shoulder exposures is needed.

The aim is to develop and evaluate a Shoulder-Café intervention to reduce high occupational mechanical shoulder exposures and prolonged shoulder complaints.

The specific objectives are:

I. To evaluate the effectiveness of the Shoulder-Café as compared to the control-intervention, the Shoulder-Guidance, measured on reductions in shoulder complaints.

II. To evaluate the effectiveness of the Shoulder-Café as compared to the Shoulder-Guidance measured on reductions in occupational mechanical shoulder exposures.

III. To identify the influence of shoulder exercises and reduced occupational mechanical shoulder exposures, respectively, on shoulder complaints.

The hypothesis is that the Shoulder-Café will reduce shoulder exposures and shoulder complaints more effectively than the Shoulder-Guidance. Furthermore, a hypothesis is that fear avoidance beliefs is reduced and the degree to which the participants feel informed about the nature of their complaints and their remedies is increased more effectively with the Shoulder-Café compared to the control intervention.

Method:

The project consists of a two-armed, cluster-randomised controlled trial with randomisation at company level (objectives I and II) and a prospective cohort study based on the cluster-randomised study (objective III).

Follow-up: A questionnaire 3 and 9 months after end of intervention with e.g. OSS.
