“…These techniques can be placed in the following groups: invasive techniques (injection therapy, MTrP dry needling, etc) and noninvasive techniques (massage, stretching, ultrasound [US], etc). 16 Taking into account the recent increase of computer use, 17 the aim of the present study is to investigate the immediate effects of ischemic compression (IC) and US on the MTrPs of the trapezius muscle. We have chosen the teaching and research personnel (TRS) of the Faculty of Experimental Science and Health and the administration and service personnel (ASP) of CEU-Cardenal Herrera University (CEU-CHU), Valencia, Spain, for this study, being workers who spend much of their time in front of a computer.…”

“…The positive value indicates flexion and negative value refer to extension. For the ease of comparison, the data of postural angle was grouping into interval of 5.The result obtained are not much different from the study done by Dumas, Upjohn [1]that identified the deviation of trunk posture of women during computer work was approximately -2 to 10 degree . The difference with result of the current study may be related to the age of the subjects.…”

Abstract. Few studies have investigated sitting posture and muscle activity during computer work. This study aims to determine sitting postural angle and its influence on neck and low back muscle activity in ageing women workforce during computer task. Seventeen female workers aged 50 and above participated. Surface electromyography activity was recorded from cervical erector spinae, lumbar multifidus, longgisimus and iliocostalis in 20 minutes computer task. Concurrently inclinometer recordings from upper trunk and pelvis were used to determine back posture. The results for the upper trunk angle show that the posture deviates from the sagittal plane in range -10 to 10 degree during the task. While the pelvic rotated forward and backward in range -15 to 15 degree.Neutral sitting posture with slight extension or flexion of the upper trunk and pelvic posture performed by ageing women workforce during computer work cause reduction in muscle activity. Higher level of muscle activity was indicated in back flexion rather than back extension.

“…30 Se estima que afecta a la mitad de las mujeres embarazadas, de las cuales el 25% experimenta dolor importante y el 8% presenta severa discapacidad asociada. 18 Si bien se ha planteado que el estado nutricional, comprendido desde el Índice de Masa Corporal (IMC), se relaciona con la presencia de molestias músculo-esqueléticas, una reciente revisión demostró que la estatura y peso materno es un factor de riesgo de dolor lumbar con baja evidencia científica como causal de esta sintomatología. 13 Esto se condice con los resultados obtenidos en este estudio, ya que no se encontró relación estadísticamente significativa entre las molestias músculo-esqueléticas e IMC en mujeres embarazadas.…”

“…Respecto al punto anterior, distintas publicaciones han establecido la necesidad de realizar intervenciones en los puestos de trabajo de embarazadas. [7][8][9][10] Los principales ejes a intervenir son: a) La presencia de factores de riesgo de Trastornos Músculo-Esqueléticos Relacionados con el Trabajo [11][12][13][14][15] ; b) Disminuir los factores de riesgo ergonómicos presentes en puestos de trabajo de embarazadas 16,17 ; c) Disminuir la carga cognitiva de los puestos y jornadas de trabajo [18][19][20][21] ; d) Controlar los factores psicosociales 21 , entre otros. Esto es sustantivo con la existencia de distintos estudios sobre intervenciones que han demostrado tener impacto en la sobrecarga física y mental de la mujer en sus puestos de trabajo.…”

Tanto a nivel internacional como nacional la inserción de la mujer en el mundo laboral es cada vez mayor, y se estima que esta seguirá en aumento.1 En Chile, la tasa de ocupación de la mujer del trimestre diciembre-febrero 2010 es del 37,8%. En relación a la distribución porcentual de la ocupación: "El sector primario es el tercero en importancia porcentual de la ocupación femenina, tras el sector terciario (85,3%) y el sector secundario (9,8%)".2 A su vez, se ha evidenciado un patrón de exposición de factores de riesgo en el lugar RESUMENSe ha identificado una sobrecarga laboral en mujeres durante el embarazo. Suelen presentar una alta prevalencia de trastornos mús-culo-esqueléticos, no obstante existe poca evidencia sobre su progresión en los trimestres y asociación con carga de trabajo. Objetivo: Describir la carga de trabajo, factor físico biomecánico y percepción de molestias músculo-esqueléticas (PMME) en trabajadoras embarazadas. Material y método: Estudio de diseño observacional, descriptivo y transversal. Muestreo por conveniencia de 80 mujeres embarazadas de la Unidad de Medicina Materno Fetal del Hospital Clínico de la Universidad de Chile. Se describe la muestra a través de la evaluación de carga de trabajo, factores físicos biomecánicos, dificultades percibidas al realizar su tarea mediante una hoja de recolección de información diseñada específicamente para la investigación, usando metodología en ergonomía Resultados: Las PMME presentan una prevalencia de un 90%, destacando la zona de la espalda baja y cadera/nalgas/muslos. Las posturas mantenidas o forzadas fueron el factor más prevalente. Una de cada 6 embarazadas refirieron continuar realizando manejo manual de carga. La mayoría de las trabajadoras presentaron un alto riesgo en su carga de trabajo. Conclusiones principales: Las embarazadas están expuestas a altos niveles de carga de trabajo determinado por exigencia mental. ABSTRACTIt have been detected overload work among women during pregnancy. Often they present a high prevalence on HYPERLINK "https:// www.google.cl/search?q=work+related+musculoskeletal+disorder&s pell=1&sa=X&ved=0ahUKEwiw2IS2gePTAhWDD5AKHbK5DcoQvw UIIigA" work related musculoskeletal disorder; however there is little evidence about their progression during the pregnancy´s trimester and the association with work load. Objective: Describe work load, physical and biomechanical factors, perception of musculoskeletal discomfort (PMSD) in pregnant women. Materials and methods: Observational, descriptive and cross-sectional study. Sampling by convenience of 80 pregnant women of the Maternal-fetal care unit of the Clinical Hospital of the University of Chile. The sample is described trough the evaluation of workload, physical and biomechanical factors, trouble performing tasks by means of a sheet of collection of information created for this investigation, using ergonomics methodology. Results: The PMSD present a prevalence of 90%, stands out the lower back and hips/buttocks/thigh areas. The forced or maintained postures ware the ...
