User manual MULHOLLAND PEER LEVEL PRONE ASSEMBLY

[. . . ] Three important measurements to insure the column is properly positioned on the frame are: (fig 5A) 14 3/4 from the top of the pivot clamp to the top of the main column piece; (fig 5B) 4 from bottom of pivot to the top of the gas strut; (fig 6C) 16 3/16 on a diagonal from the front of the pivot bar to the back end if the top cross brace. Figure 6 Figure 5 A 14 3/4 B4 C 16 3/16 6 5. Attach the upper end of the gas strut to the receiver mounting (fig 7A) on the main column. Then attach the lower (and thinner) end of the black gas strut to the black plate between the cross bars (fig 7B). [. . . ] This allows the child to stand as close to the floor (peer level) as possible. NEVER MAKE ANY OF THESE ADJUSTMENTS WITH THE CHILD IN THE STANDER!Foot Support: Initially, measure from the foot support to the knee pad and lower or raise the foot supports to the desired height (floor to mid-knee measurement) with the push pin (fig 12A). Note: Fine tuning instructions for the Foot Supports to follow. Trunk Support: Removing both push pins (B & C) pull the column up to the correct height for the chest support and put trunk pin (B) in place. Place the chest support (D) to approximately the level of the child's clavicles. Hip Support: Pull the hip support up to the desired height (heel to iliac crest measurement) and replace the pin (C). Hip and Trunk Support Widths: Loosen the black knobs (E) and slide the bars to the appropriate width (you may need to loosen the straps). It is very important to make sure that the outsides of the bars are an equal distance from the mid-line of the column. If they are not, the child may not be weight bearing evenly. Tighten the knobs and re-velcro the inside strap. This will be adjusted later as part of the "fine tuning" while the child is in the stander. Complete this adjustment for both the trunk and hip supports. 12 Tray support: Adjust the height of the tray by lifting the tray to the desired height, loosening the allen screws on the stops (F), placing the stops at the appropriate height, and retightening the screws. D B C F E A Figure 12 13 Adjustable Knee Supports 1) Angle: Loosen the allen screws (fig 13A) and tilt to the appropriate angle to support the knees. 2) Width: Loosen screws (A) and slide to the correct width to assist in alignment of the lower extremity. 3) Height: Small height adjustments can be made by loosening screws (B) and moving the knee pad on the vertical post. 4) DO NOT ADJUST THE PLACEMENT OF THE COLUMN BRACKET (F) ON THE STANDER!Foot Support Adjustments: 1) Footplate Height: Release the push pin(fig 13C), and adjust the height. 2) Five-Way Foot Supports: a) Height: Release the push pin(C), and adjust the height. b) Leg length discrepancy: Lower foot support to accommodate the lower leg by releasing the push pin (C) and placing it at the appropriate height. Then unscrew the side with the shorter leg and adjust accordingly. c) Abduction: Loosen the screws (D) and adjust the width between the shoe holders. Note: Excessive abduction may cause increased weight-bearing on the medial borders of the feet. [. . . ] The child should be directly supervised at all times. Provide a table or socialization activity while the child is standing. Observe the child closely for signs of fatigue, distress, or discomfort, and remove the child within the prescribed period. 18 MAINTENANCE: 1. The metal and plastic parts can be washed with a mild concentration of dish soap (the same as is used on your dishes). [. . . ]
