Abstract

Introduction. The pandemic forces jobs to increase the number of hours when using new computer technologies, this causes repetitive movements and problems related to tenosynovitis in workers who carry out these activities. Objective. Implement an ergonomic prevention plan to reduce the prevalence of musculoskeletal discomfort and Quervain's tenosynovitis in the statistics area of ​​the Puyo General Hospital. Methods. For the diagnosis of musculoskeletal discomfort, the Nordic questionnaire was used, then an analysis was carried out prior to the execution of an ergonomic prevention program and subsequent evaluation with the OCRA Check List Method to determine the effectiveness of the measures. Results. From the application of the Nordic Questionnaire, it was observed that 65% of the workers presented musculoskeletal discomfort and 85% of the causes indicated that they were due to repetitive movements of the hand and wrist with an age range of 35 - 45 years. After applying the ergonomic prevention plan that considered the following activities: a) active pauses, b) correct location of computer peripherals, c) cell phone suspension in the recovery period, an 80% reduction in the Index score was achieved. OCRA with values ​​of 5.25 for the right side and an acceptable risk, in addition a value of 4.87 and an optimal ergonomic risk for the left side. Conclusion: When executing an ergonomic prevention plan, the level of ergonomic risk was lowered by 80% with the application of active breaks, reduction of the time of use and improvement in the use of electronic peripherals and restricting the mobile phone during the recovery time.
