A leg aid device and method for increasing the stamina of a body-supporting user's leg for repeated flexure and extension at the knee. The device comprises elongated flexibly resilient biasing means (14) for placement in approximate alignment with a user's leg from a level near the ankle area up to at least the level of the midthigh area. The biasing means (14) is adapted to bias a user's leg toward a straightened condition without significant torsion or twisting of the leg. Holding means (18, 20) maintains the biasing means (14) approximately aligned upon a user's leg for bending yieldingly therewith during flexure thereof at the knee. The biasing means (14), when held by the holding means (18, 20) upon a body-supporting user's leg, functions to support a portion of the user's body weight during times the biasing means (14) is in bent condition with the user's leg in flexed condition, and functions to aid the user's leg muscles in causing extension of the user's leg from flexed condition as the biasing means resiliently returns toward a straightened condition with the extension of the user's leg. |
