The benefits of using this system can be profound, not only in terms of gait development, but also in terms of increasing the child s independence, self confidence and social interaction. DESIGN GOALS The WalkaboutTM is designed to give a child the potential for hands-free, self-initiated movement while providing lateral support and assisted lift. This spring-assisted lift allows for graduated weight relief as the child develops skill and standing tolerance. The adjustable pitch of the column, along with the pelvic and trunk supports, can be utilized to direct weight shift and assist with stepping. PRECAUTIONS 1. [. . . ] Pelvic support height: Loosen the two adjustment levers (3) on the back of the pelvic support clamp plates. Place the pelvic support assembly as close to the sit bar as possible without preventing hip flexion. If this support is too high or too low, it will not provide the stability required for the child to step forward. Trunk support height: Loosen the two adjustment levers (4) on the back of the trunk support clamp plates. Position the trunk support so the distance from the top of the trunk support to the top of the sit bar is equal to measurement #3. The child s shoulders should be positioned slightly in front of his/her 1 lower body and feet (in most situations) with the pitch of the column at approximately 85 degrees Figure 9 to the floor. Occasionally the column will be positioned in a more upright, or more prone position, to improve the child s gait pattern or to diminish primitive reflex patterning. To achieve forward tilt of the upper body, unfasten the trunk support straps, shorten the back strap, and Figure 10 lengthen the front strap. Lengthening the back strap and shortening the front strap tilts the upper body backward. If more pitch is needed, the rear column can be tilted forward. Loosen the two allen screws on the upper tube clamp assembly (fig. 9. 1). Raise the upper clamp assembly and frame brace while tilting the column forward (fig 10). When the desired angle is achieved tighten the allen screws to secure the column. Note: lowering the upper tube clamp assembly will tilt the column back upright. 11 Column Height: Refer to figure 11. After setting the pitch and the sit bar-to-trunk support distance, set the column height. 3 2 1 1. Measure the inseam: Determine the child s inseam height: ____ a) If the child requires support at the upper trunk to stand, measure from the floor to 2 Figure 11 inches above the inseam. b) If the child requires only hip support to stand, measure from the floor to the inseam. Adjust the Column Height: a) Loosen the T-nut (1) and then remove the ball lock pin on the rear column adjustment tube. b) Slide the rear column (2) up/down so that the sit bar height is the same as the inseam height determined above. c) Replace the ball lock pin and tighten the T-nut to secure the rear column in place. d) For more precise adjustments, rotate the crank (3) clockwise to raise the column assembly or counterclockwise to lower the column assembly. 12 Spring Tension: Refer to figures 12. The sit bar, pelvic support, and trunk support assist in lifting the child into standing. The amount of lift is controlled by the degree of spring tension. [. . . ] Release the ring and ensure the tray locks into place. Removing the tray: The tray must be removed to place the child in or take the child from the Walkabout. This is done by pulling the rings on the spring clamps (1) and lifting the tray off the support bars. 17 Double Sit Bar: Refer to figure 20 1. Slide the sit bar onto the front column. [. . . ]
