[Comprehensive ergonomics program for the reduction of musculoskeletal discomfort in computer user workers].

INTRODUCTION

Musculoskeletal complaints represent one of the main problems that affect the well-being and work performance of computer users demanding interventions with a comprehensive approach where workers actively participate.

OBJECTIVE

To evaluate the effect of a comprehensive ergonomics program to reduce musculoskeletal discomfort and postural overload in computer user workers.

METHODS

A quantitative study with an analytical approach and quasi-experimental design with independent groups was carried out during 3-month. 242 people participated, divided into 2 groups of 121 people each, who used a computer for more than 4h a day. The experimental group participated in the ergonomics program that included training, delivery of an informative leaflet on ergonomics in offices, adaptation of the workstation and a stretching exercise program. The control group received training and only once the information leaflet. A baseline measurement of musculoskeletal discomfort and postural overload was performed in both groups. At the end of 3months, a second data collection was carried out and compared with the baseline data.

RESULTS

The ergonomics program significantly reduced the intensity of musculoskeletal discomfort in the different neck, shoulder and back segments (P<.05), but did not reduce the frequency of discomfort (P>.05). Furthermore, the program significantly reduced the level of postural overload (P<.05).

CONCLUSION

The comprehensive ergonomics program was effective in reducing the intensity of musculoskeletal complaints and postural overload, but did not significantly reduce the frequency of musculoskeletal complaints.
