ABSTRACT:
A walker brace for temporary tightening from a close fit position during the support surface contact phase of gait when the patient'weight is applied to the sole to stabilize the leg, ankle and foot from undesirable movement. A leg support assembly (2) of the brace has multiple straps (15, 16) connected to an arm (4) for nesting the leg. A foot support assembly (3) has multiple straps (31, 32) connected to a foot support shell (28) for nesting the foot. An arm (5) is connected to the foot support shell (28) and articulates relative to the arm (4) at a controlled motion ankle hinge (6). A leg strap tightening mechanism (18) includes a tightening rod (20) and a cable (22) for progressive and differential tightening of the straps (15, 16) to stabilize the leg. A foot strap tightening mechanism (44) includes a buckle loop (34) and a cable (41) for tightening of the instep strap (32) to stabilize the foot. The cables (22, 41) pass through foot support shell (28) and a rocker bottom sole shell (29) pivoted at the foot support shell (28). A relative shortening of the cables (22, 41) occurs when the rocker bottom sole shell (29) is pivoted upwardly relative to the foot support shell (28) during the period of time that the patient's weight is applied to the sole.
