A workplace exercise versus health promotion intervention to prevent and reduce the economic and personal burden of non-specific neck pain in office personnel: protocol of a cluster-randomised controlled trial
MetadataShow full item record
Introduction Non-specific neck pain is a major burden to industry, yet the impact of introducing a workplace ergonomics and exercise intervention on work productivity and severity of neck pain in a population of office personnel is unknown. Research question Does a combined workplace-based best practice ergonomic and neck exercise program reduce productivity losses and risk of developing neck pain in asymptomatic workers, or decrease severity of neck pain in symptomatic workers, compared to a best practice ergonomic and general health promotion program? Design Prospective cluster randomised controlled trial. Participants and setting Office personnel aged over 18 years, and who work > 30 hours/week. Intervention Individualised best practice ergonomic intervention plus 3 נ20 minute weekly, progressive neck/shoulder girdle exercise group sessions for 12 weeks. Control Individualised best practice ergonomic intervention plus 1-hour weekly health information sessions for 12 weeks. Measurements Primary (productivity loss) and secondary (neck pain and disability, muscle performance, and quality of life) outcome measures will be collected using validated scales at baseline, immediate post-intervention and 12 months after commencement. Procedure 640 volunteering office personnel will be randomly allocated to either an intervention or control arm in work group clusters. Analysis Analysis will be on an 'intent-to-treat' basis and per protocol. Multilevel, generalised linear models will be used to examine the effect of the intervention on reducing the productivity loss in dollar units (AUD), and severity of neck pain and disability. Discussion The findings of this study will have a direct impact on policies that underpin the prevention and management of neck pain in office personnel.
