Evaluación ergonómica con el método Rula al personal instrumentista de la Orquesta Sinfónica de Cuenca durante el período junio a noviembre del 2016

Abstract

Background. According to the literature, the prevalence of musculoskeletal injuries instrumentalist staff goes from 32% to 87% due to the constant repetitions and misused positions during use of the instrument, these being the main causes that affect their biomechanics corporal1-2.

General Objetive. Ergonomically evaluate the RULA to plant personnel performer Symphony Orchestra of Cuenca during the period June to November 2015.

Methods and Materials. A quasi-experimental study was conducted with 35 instrumentalists plant, starting with an evaluation through RULA based on an observational and photographic analysis of ergonomics when executing its instrument, then it proceeded with a kinesioterapéutica based intervention exercises heating and stretching and training with topics related to our research. Finally a reassessment with RULA was performed.

Results. The results were : Ergonomic High Risk : right (60 % ) and left ( 54.29 % ) side denoting the absence of Ergonomics in : Law ( 28.57 % ) and left ( 31.43% ) and medium risk ergonomic side instrumentalists . After the intervention decreased to a low level of ergonomic risk for both the right and left side of (100 %).

Conclution. The investigation was satisfactory but several factors that affect the ergonomics found: Infrastructure (low light, low temperature areas, noisy environment, confined space) Inputs (anti ergonomic chairs, inadequate lecterns), brackets and accessories that do not have the musicians (ergobrass, harness, pads, supports thumbs)
