“Intervención en las alteraciones músculo-esqueléticas mediante la aplicación de pausas activas en el personal que labora en el sis ecu - 911 en la provincia de Tungurahua”

Abstract

The musculoskeletal disorders (MSDs) are frequently associated with the ergonomic factor risks which characteristic include the labor stress, awkward posture or neutral position deviation of body while doing work activities. These disorders appear frequently in the neck, shoulders and low back. So, the present research aims to decrease impact of musculoskeletal disorders through the application of active breaks in staff working in the SIS ECU – 911, who keep prolonged sitting position during all the work day. In addition to this, sedentarism predisposes them to development these. This research has a quantitative, experimental and descriptive approach. t is started with the evaluation of ERGOPAR V2.0 method, ergonomic evaluation ISO 11228-3 part 3: handling of low loads at high frequency, visual analogue scale (VAS), cervical spine goniometry. Also, Adams, Fingertips-to-floor distance (FTF), Spurling and Romberg test. The active breaks program intervention was applied to 76 participants, 4 interventions per week for 9 weeks. The correct exercises execution individually in the workplace was taught and controlled. Active breaks started with breathing exercises, joint mobility and held stretching of cervical, dorsal, lumbar, upper and lower limbs muscles. After the active breaks program intervention and the final evaluation with the applied test, the reduction of the impact of musculoskeletal disorders of staff working is determined.
