Systematic Work Environment Model Incorporating Web-based Neck-specific Exercise for Dental Staff With Neck Pain: A Prospective Randomized Controlled Study (WorkCIT)
Systematic Work Environment Model Incorporating Web-based Neck-specific Exercise for Dental Staff With Neck Pain: A Prospective Randomized Controlled Study (WorkCIT)
The aim of study; WorkCIT is to investigate whether managerial support in using systematic work environment evaluation and adjustment (SWEA) with/without additional 3 month web-based NSEs with four visits to a physiotherapist is effective in promoting reduced neck pain and disability among dental health care professionals (DHCP) with work-related neck pain (WRNP).
The aim of the subgroup studies is to investigate biomarkers and tissue changes and the association with pain, work ability, and other outcomes before and after SWEA with or without NSEs. Furthermore, to investigate dental staff experiences with the interventions and their impact on work ability, health and their work situation, and investigate managers experience of SWEA with support from the Prehab guide and workshops.
The hypothesis is that a combined effort with SWEA to promote the work situation together with NSEs will reduce neck pain intensity and improve work ability to a greater extent than the SWEA only.
Methods and analysis: This is a prospective, longitudinal, randomised, controlled multi-centre trial with two parallel treatment arms and blinded investigators conducted according to a detailed protocol following the guidelines in the CONSORT checklist. A total of 240 DHCP with WRNP will be recruited. The main outcome is neck pain intensity. Secondary outcomes are work ability, function, health-related quality of life, work absenteeism, work-related factors, and work adjustments made. Cost-effectiveness will be studied from a societal perspective if significant differences appear between randomization groups regarding health-related quality of life and will in that case be reported in a separate paper. To improve diagnostics and help assess the effectiveness of intervention biochemical sub-group studies will be performed before and after intervention to investigate pain related biomarkers. Interviews with a sub-group of participants and managers will be performed regarding work-ability, work adjustments and experiences of interventions.
Introduction: Neck pain among dental health care professionals (DHCP) is a growing societal problem. It is compulsory by law, for managers to work with systematic work environment evaluation and adjustment (SWEA), though managers knowledge of this approach is often deficient. Managerial support in using SWEA to enhance employees' work situation has not been investigated in regards to work-related neck pain (WRNP). Clear guidelines on interventions for WRNP are lacking. Neck-specific exercise (NSE) is the method with the most evidence regarding treatment for neck problems in general but has not been investigated for WRNP. The aim of study; WORKCIT is to investigate whether managerial support in using SWEA with/without additional 3 month web-based NSEs with four visits to a physiotherapist is effective in promoting reduced neck pain and disability among DHCP with WRNP. More specifically, the main project aims to: Compare the effects of SWEA with a focus on adjustments at work and support for DHCP (aimed for all staff) by their manager with the addition (half of the staff) of an E-health solution of NSEs in combination with four visits to a physiotherapist with regards to neck pain intensity, disability, work ability, health, and cost-effectiveness; Investigate whether a participatory approach of workshops and digital education for managers in SWEA/ Prehabguiden Suntarbetsliv (Prehab guide) enhance the work environment (organisational, social, and physical), including individual support and adjustment of the work situation, reducing their neck pain intensity; Investigate if NSE reduces WRNP in addition to SWEA; Identify underlying factors associated with the outcome following work interventions with or without exercise regarding pain, work ability, and health.
The aim of the subgroup studies is to investigate biomarkers and tissue changes and the association with pain, work ability, and other outcomes before and after SWEA with or without NSEs. Furthermore, to investigate dental staff experiences with the interventions and their impact on work ability, health and their work situation, and investigate managers experience of SWEA with support from the Prehab guide and workshops.
The hypothesis is that a combined effort with SWEA to promote the work situation together with NSEs will reduce neck pain intensity and improve work ability to a greater extent than the SWEA only.

Secondary outcomes are work ability, function, health-related quality of life, work absenteeism, work-related factors, and work adjustments made. Cost-effectiveness will be studied from a societal perspective if significant differences appear between randomization groups regarding health-related quality of life and will in that case be reported in a separate paper. To improve diagnostics and help assess the effectiveness of intervention biochemical sub-group studies will be performed before and after intervention to investigate pain related biomarkers.

Ethics and dissemination: The study is approved by the Swedish Ethical Review Authority. The processing of personal data according to the General Data Protection Regulation will be registered at Linköping University before the start of the study. The results will be published in scientific journals, presented at scientific conferences and in meetings with caregivers, disseminated in lectures to the medical faculty and patient associations, and communicated in the media.
