Evaluation of i-Préventive: Active prevention digital tool for musculoskeletal disorders among computer workers

Abstract

To evaluate the effects of a software program that stimulates extra breaks with a personalized self-program exercises form, on pain and/or function, among computer workers who have upper-limb musculoskeletal disorders with visual discomfort [1] . A cluster randomized controlled trial was performed. Each group was composed of symptomatic and asymptomatic employees. We conducted a prospective feasibility study developed in two different sites of Michelin firm. Cluster randomization was used for office locations. The study lasted 5 months. The main outcome was the overall recovery from complaints after one-month intervention, using “the Nordic style questionnaire” and eyestrain questionnaire [2] . 96 workers included in the intervention group, 79 in the control group. The most painful areas (VAS ≥2) are: neck (40%), upper back (18.8%), shoulders (15.7%). Concerning, the most painful anatomical area, the Nordic score significantly decreases after one month utilization in the intervention group ( P = 0,038) versus control group ( P = 0.59). After one-month utilization, in the intervention group, the painful area and visual discomfort symptoms number decrease ( P = 0.02). After one month, the adhesion of the system is satisfactory (almost 60% of employees). In the short-term, the active breaks use in the musculoskeletal disorders and eyestrain treatment is effective using the software program. It is a numerical simple tool to use, which allows each worker to interact on areas of their choice by offering personalized exercises easily achievable on workplace.
