“…They found that as well as improving driver comfort without distracting the driver, EMG measurements of muscle activity in the shoulders and upper back were reduced. Automotive dynamic sitting can be induced through support mechanisms denominated in literature as micro-adjustment or massage (Kolich et al, 2001) and active seating (e.g., Active Lumbar Systems (Holmes et al, 2013) applied on the lumbar or thoracic region of the spine (Gruevski et al, 2016). Seat configuration variation can also be used to promote passive posture changes, for example, van Veen et al (2015) conducted a study using a driver seat with varying configuration, 1.5° movement backwards of the backrest and 1° upwards and downwards tilt of the seat cushion.…”

The concept of introducing movement in automotive seating was investigated. Three seat conditions, a control (no movement) and two movement conditions (fore-aft and cushionbackrest) were compared. Movement was introduced at a fixed speed, slow, smooth and within a small range. Ten participants took part in a 60 minute simulated drive for each condition-single blind, repeated measures, and balanced order. Discomfort ratings were collected for six body areas and overall discomfort, together with a wellbeing questionnaire. Driver posture and Seat Fidgets and Movements (SFMs) were captured. There was a trend for lower ratings of discomfort, overall and in the neck, shoulders, lower back, buttocks, and ankles with both seat movement conditions. Wellbeing ratings were also better with movement. Significant differences were found at minute 60 for buttock discomfort-less discomfort with seat movement. Overall discomfort and SFMs frequency increased with time driving. Generally, passive seat movement was well received.

“…Este problema es frecuente y grave en el personal policial (17) . Si bien es cierto, la actividad de la policía está expuesto a una serie de factores que podrían afectar su salud y producir incapacidad física Algunos realizan funciones internas como las actividades administrativas, otros hacen el patrullaje, permaneciendo por muchas horas de pie y con el uso de equipos, sumando las condiciones de trabajo, pueden conducir a una sobrecarga de la columna (18) .…”

Introducción: El dolor lumbar es un problema que conlleva limitación funcional y puede afectar la salud mental del personal policial. Objetivo: Determinar la asociación el dolor lumbar con ansiedad y depresión en policías de una comisaría en Lima. Métodos: Investigación transversal analítica, con 110 participantes, a partir de un muestro probabilístico, llevado a cabo en la comisaria de Monserrat en Lima. Se utilizó el cuestionario para medir dolor lumbar en el personal policial "CDLPP", que pasó por juicio de expertos y tuvo un alfa de Cronbach de 0,914; para medir ansiedad y depresión se usó el test de Zung. Resultados: Un 75,5% de policías padecen dolor lumbar. Asimismo, se evidencio una relación estadísticamente significativa entre la ansiedad y el dolor lumbar (p=0,028). Pero no se evidenció una asociación estadísticamente significativa entre el dolor lumbar y la depresión (p=0,740). Conclusión: El dolor lumbar se asocia a la ansiedad en los policías una comisaría en Lima. Asimismo, un alto porcentaje de policías padecen dolor lumbar, teniendo en consideración que es un problema de salud pública, podría conllevar a futuro algún tipo de discapacidad afectando su calidad de vida.

“…During the experiment, the participants were required to wear sportswear and thin tight pants. The measuring procedure of the seated pressure method was relatively simple, resistant to the influence of human factors, and has been commonly used by previous studies 5 , 6 ) . The mFLEX pressure mapping system (Type 5E, Vista Medical LTD., Netherlands) was adopted for the seated pressure measurement ( Fig.…”

[Purpose] Using two measurement methods, this study measured the external ischial tuberosity widths (EITW) of both males and females and investigated gender differences in these EITW values. [Subjects and Methods] Fifteen male and 15 female Taiwanese were recruited for this study. Their EITWs were measured using the impress and the seated pressure methods, and compared. [Results] The results show that the EITW values obtained using the impress method were similar to those reported by previous studies, but gender differences were observed in the measurements when that method was used (male: 11.96 cm; female: 13.53 cm). However, the males had non-significantly greater EITW values than the females when the seated pressure method was used (male: 13.42 cm; female: 13.30 cm), and this was probably due to the distinct characteristics of the buttocks of the two sexes and the seated pressure method. [Conclusion] The authors of this study propose that 12.0 and 13.5 cm are respectively the ideal design parameters for male and female EITWs in Taiwan, although13.5 cm might be more appropriate for male EITWs in the design of relatively hard seat or saddle surfaces.
