Abstract
Optimum lumbar alignment is achieved and maintained in a human subject through forced contraction of the subject's psoas major muscles while in a seated position. A flexible thigh strap attached to a seat or chair in which the subject seats restrains the anterior portions of the subject's thighs proximate the subject's knees from upward movement. The human subject forces his thighs upwardly against the strap and forces the balls of his feet downwardly against the ground or floor on which the seat or chair is supported. This causes the subject's psoas major muscles to flex and produces a flattening of his/her lumbar spine which assists in relieving chronic backache.
