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. [. . . ] Seat height: Loosen the 4 allen screws (2) and slide the seat 2 along the front column. Initially place the seat as high as possible on the column. Hip support height: (Refer to figure 7. ) Loosen the two 9 adjustment levers (3) on the back of the pelvic support clamp plates. Place the pelvic support assembly as close to the seat 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 3 top of the trunk support to the top of the sit bar is equal to measurement #3. Tighten both adjustment levers. Figure 7 4 Pitch: The child s shoulders should be directly over, or slightly in front of, his lower body and feet (in most situations) with the pitch of the column at approximately 85 degrees 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. 10 (Pitch continued) There are two ways to adjust the pitch, or forward tilt, of the WalkaboutTM: 1. Move the child s trunk further forward in the support. b) Shorten the back strap and lengthen the front strap of the trunk support. Note: Lengthening the back strap and shortening the front strap will tilt the upper body back upright. a) Loosen the four allen screws on the upper tube clamp assembly. b) Raise the upper clamp assembly (and frame braces) while tilting the column forward. c) 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 backward. Figure 8 Figure 9 11 Column Height: Refer to figure 10. After setting the pitch and the seat-to-trunk support distance, set the column height. 3 Figure 10 12 1. Measure the inseam: 1 Determine the child s inseam height: ____ a) If the child requires support at the upper trunk to stand, measure from the floor to 2 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 levers (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 seat height is the same as the inseam height determined above. c) Replace the ball lock pin and tighten the levers to secure the rear column in place. [. . . ] Connect the cross bar (1) to the back 5 2 column/seat 6 post with 1 four allen 3 Figure 21 screws (2). Slide the arm trough tubes (4) into the clamps on the cross bar, and tighten the allen screws to secure. Height: loosen the clamp situated on the end of the extension tube (3), this enables the arm trough tube (4) to be inserted at desired height 2. Width: Loosen the clamping screw and remove the ball lock pin. [. . . ]
