Abstract

A walker device is described herein including two side frames, each side frame comprising a front vertical support, a rear vertical support and at least one connecting member extending between the front and rear vertical supports. The walker device further includes a cross bar extending between the two side frames and pivotally connecting to the front vertical supports of the two side frames. The walker device also includes a tension device which applies a resistive force to the pivoting motion between the first cross bar and the two side frames. The walker device is therefore capable of a pivoting configuration which enables the user to learn or re-learn a more natural gait pattern including rotation of the upper and lower body. Some embodiments of the walker device include a second, auxiliary cross bar that is parallel to the first cross bar and horizontally offset from the first cross bar.
