  • Publication number: 20020144723
    Abstract: A pair of crutches of walker type, each being made with a moveable, spring-loaded shoulder support. The shoulder support incorporates an eye bolt that pivots at its center axis from the shoulder support, then down through a flat stock steel spring. It follows through a crossmember which secures both sides of the crutch. The spring action at the shoulder support acts as a cushion when the individual's body weight is shifted. This creates a forward, and rear movement with each stride. This pivoting, spring action provides the user comfort and less pressure and shock under the arm pit area.
