FRAGMENTO

Introducción

Diferentes investigadores refieren que más de un tercio de todos los trabajadores tienen que trabajar de pie y/o caminando por periodos mayores a 4 horas al día. La postura prolongada de pie, definida como aquella que se mantiene más de 2 horas al día, se ha vinculado con diferentes problemas de salud como por ejemplo:

1) Lumbalgia (Drewezynski 1998, Hansen 1998, Redfern 1995)
2) Dolor en pies y piernas (Drewezynski 1998, Hansen 1998, Redfern 1995)
3) Fascitis plantar (Rys 1994)
4) Restricción del flujo sanguíneo (Hansen 1998, Goonetilleke 1998)
5) Hinchazón de piernas y pies (Drewezynski 1998, Hansen 1998)
6) Venas varicosas (Drewezynski 1988)
7) Incremento de cambios óseos degenerativos (osteoartrosis) en piernas y rodillas (Manninen 2002)
8) Embarazos pretérmino y bajo peso al nacer (Mozurkewich 2000, Hae E 2002)
