Orthotic walker

Abstract

An orthotic walker comprises an orthosis (60) mounted on a wheeled frame (10) which includes a first or rearward transverse frame member (11) having thereon an attachment device (17) for releasably mounting a support member (20) adapted to carry said orthosis (60) and a connection assembly (13, 33) for the releasable connection of forwardly extending lateral frame members (30) with an optional removable forward transverse frame member (50). The first frame member (11) carries a pair of laterally spaced wheels (16) and the lateral frame members (30) each carry a further wheel (41) at the forward end thereof. Several interchangeable lateral frame members (30, 30A) are provided whereby the overall width of the frame (10) can be varied by selecting lateral frame members (32, 32A) of differing size. The support member (20) which carries the orthosis (60) is one of a plurality of interchangeable support members (20, 20A) provided in a range of sizes to suit patients of differing height and weight. The orthosis (60) comprises a back member (61) carrying a pair of lateral arms (64) mounted adjustably thereon, and each said arm (64) includes a pivotal mounting (65) by means of which a respective leg support (70) is suspended. Each leg support includes an upper element (74) having a pivotal mounting (71) at its upper end whereby it is connected to a back support, a lower element (75) having a foot support member (100) at its lower end, and an intermediate pivotal connection (72) whereby the upper and lower elements are connected to one another, wherein the upper and lower elements (74, 75) of the leg supports (70) are releasably and adjustably secured to the upper pivotal mounting (76), to the intermediate pivotal connection (72) and to the foot support member (100), so that the effective length of each of said elements can be adjusted independently.
