Participatory Intervention Among Construction Workers (IRMA11)

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.

Treatment and study plan

Participatory Intervention

Behavioral

Control

Behavioral

Primary outcomes

  1. Excessive physical load

    Time frame: 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 outcomes

  1. Pain intensity (0-10)

    Time frame: 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.

  2. WAI questionnaire

    Time frame: change from baseline to 3 months follow-up

    Work Ability Index (Ilmarinen et al)

  3. Self-efficacy Questionnaire

    Time frame: change from baseline to 3 months follow-up

    Self-efficacy to improve the physical work environment

Other outcomes

  1. Social Capital questionnaire

    Time frame: change from baseline to 3 months follow-up

    Social Capital within work teams, between work teams, and between teams and their leaders Reference for questionnaire: http://www.ncbi.nlm.nih.gov/pubmed/26261190
