Abstract

UNA PIERNA Y SOPORTE PROTESICOS SE CARACTERIZAN POR MIEMBROS DE SOPORTE SUPERIOR E INFERIOR QUE TIENEN UNO O MAS ELEMENTOS DE RESORTE OPERATIVAMENTE UNIDOS O DISPUESTOS ENTRE ELLOS. LOS MIEMBROS DE SOPORTE ESTAN PREFERIBLEMENTE INTEGRADOS Y CON MOVIMIENTO DE VA Y VEN DE UNO A OTRO, DE MODO QUE FUERZAS IMPUESTAS SOBRE EL SOPORTE PRODUCEN TAL MOVIMIENTO RECIPROCO Y EL ALMACENAMIENTO DE ENERGIA EN EL ELEMENTO O ELEMENTOS DE RESORTE. LOS ELEMENTOS DE RESORTE SON CAPACES DE LIBERAR ALGO DE LA ENERGIA ALMACENADA AL LIBRARSE DE LA FUERZA. BANDAS DE CONSTRICCION PUEDEN SER UTILIZADAS PARA LIMITAR LA CANTIDAD DE DEFLEXION DE LOS RESORTES ALARGADOS, Y LA LONGITUD EFECTIVA DE LA PROTESIS PUEDE SER FACILMENTE AJUSTADA.
