Brief Summary

This study is the first that investigates the impact of a multi-component intervention combining current evidence of effective interventions with an adherence app to assess the potential benefits on productivity, neck pain, and headache.

Detailed Description

Non-specific neck pain and headache are major economic and individual burdens in office-workers. The aim of this study is to investigate the effect of a multi-component intervention combining workstation ergonomics, health promotion information group workshops, neck exercises, and an app to enhance intervention adherence to assess possible reductions in the economic and individual burden of neck pain and headache in office workers.

This study is a stepped wedge cluster-randomized controlled trial. Eligible participants will be any office-worker aged 18-65 years from two Swiss organisations in the Canton of Zurich and Canton of Aargau, working more than 25 hours a week in predominantly sedentary office work and without serious health conditions of the neck. 120 voluntary participants will be assigned to 15 clusters which, at randomly selected time steps, switch from the control to the intervention group. The intervention will last 12 weeks and comprises workstation ergonomics, health promotion information group workshops, neck exercises and an adherence app. The primary outcome will be health-related productivity losses (presenteeism, absenteeism) using the Work Productivity and Activity Impairment Questionnaire. Secondary outcomes will include neck disability and pain. Physical and health outcomes (e.g. Neck Disability Index, muscle strength, and endurance), psychosocial outcomes (e.g. job-stress index, Fear-Avoidance Beliefs Questionnaire), workplace outcomes (e.g. workstation ergonomics), and individual outcomes (e.g. socio-demographic data, adherence to intervention) will be assessed. Measurements will take place at baseline, 4 months, 8 months, 12 months, 16 months, and 28 months after commencement. Data will be analysed on an 'intention to treat' basis and per protocol. Primary and secondary outcomes will be examined using linear mixed-effects models.

This study is the first that investigates the impact of a multi-component intervention combining current evidence of effective interventions with an adherence app to assess the potential benefits on productivity, neck pain, and headache. The outcomes will impact the individual, their workplace, as well as private and public policy by offering evidence for treatment and prevention of neck pain and headache in office-workers.

Primary Outcome Measures

Name	Time	Method
Change in NP-related productivity loss	change from baseline at 16 months	Change in NP-related productivity loss will be measured in percentages of the working time, using the Work Productivity and Activity Impairment Questionnaire for Specific Health Problem (WPAI German version) and converted into monetary units using individual earnings. Absenteeism is assessed by asking the participants about the number of hours missed because of NP as well as the number of hours they have actually worked. To assess presenteeism, the participants are asked to indicate on a 10-score scale how much the NP affected productivity while working, with 0 indicating no effect on productivity and 10 indicating total disability. Scoring rules of the developers of the questionnaire will then be used to obtain self-reported absenteeism and presenteeism expressed as impairment percentages. The monetary value for the lost productivity will be obtained for each individual by multiplying the impairment percentages by the individual gross wage.

Secondary Outcome Measures

Name	Time	Method
Neck Disability Index	change from baseline at 16 months	The German version of the Neck Disability Index (NDI) will be used to evaluate the extent to which NP interferes with vocational, recreational, social, and functional aspects of living. (score from 0 to 100)
Neck pain	change from baseline at 16 months	Neck pain intensity, occurence and frequency will be measured based on existing questionnaires (Standardised Nordic questionnaires for the analysis of musculoskeletal Symptoms; Neuromuscular assessment in Elderly Workers with and without work related) (open questions and numeric pain rating scale ranging from 0 to 10).; neck/shoulder trouble).
