Participatory Intervention Among Construction Workers (IRMA11)

Not Applicable

Completed

• Conditions: Musculoskeletal Disorders
• Interventions: Behavioral: Control; Behavioral: Participatory Intervention

• Registration Number: NCT02498197
• Lead Sponsor: National Research Centre for the Working Environment, Denmark

Brief Summary

There is high prevalence of back pain and neck-shoulder pain among blue collar workers. Physical excessive exposures such as heavy lifting or working with a bended or twisted back are independent risk factors for back pain among workers in the construction industry. Participatory ergonomic initiatives increase the success of interventions aimed at reducing physical excessive exposures.

The objectives are in two phases to; 1) determine which work-tasks in selected job-groups involve the highest load of the back and shoulders during a normal working day (using EMG, Actigraphs, Video). 2) investigate whether a participatory intervention can reduce physical workloads, drawing on information from objective measurements from phase 1.

Arm && Interventions

Group	Intervention	Description
Control	Control	Receive standard information about correct lifting technics, use of assistive technology, and ergonomics
Participatory Intervention	Participatory Intervention	Participatory intervention with workers and their leaders. Workshops with presentation of work tasks with excessive physical load and subsequently plans to reduce these loads

Primary Outcome Measures

Name	Time	Method
Excessive physical load	change from baseline to 3 months follow-up	The primary outcome of the present study is the change from baseline to follow-up in frequency of events with excessive physical load

Secondary Outcome Measures

Name	Time	Method
Pain intensity (0-10)	change from baseline to 3 months follow-up	Change in "low back pain intensity during the last week" from baseline to follow-up. A horizontally oriented modified VAS scale will be used with 11 points from 0 to 10.
Self-efficacy Questionnaire	change from baseline to 3 months follow-up	Self-efficacy to improve the physical work environment
WAI questionnaire	change from baseline to 3 months follow-up	Work Ability Index (Ilmarinen et al)
