- Shape up in Prio 3A
Assess the pelvis and thigh position carefully and evaluate if the user can tolerate corrections. Fine tuning the angles can have a positive impact on the alignment of the trunk and spine, use the 3A back angle adjustments and the back straps to assess the desired sitting angles.
Seat: The thigh position is important for stability and upper body balance. Use an adjustable seat cushion or create a shape with additional cell foam wedges (1,2) that can be attached under the cushion cover directly to the foam. A pelvic obliquity can be accommodated with the Large Cell Foam Wedge (3).
Back Support: The 3D Back cusion (4) contours perfectly to the users back and the tension adjustable back straps stabilize and support the trunk.
Trunk Support: The trunk may need lateral support (5). They should be positioned higher on the side the person is leaning to and counteract further down on the opposite side.
Positioning Belt: Use a positioning belt (6) if the user has sliding problems.
Arm Support: If the user is leaning towards the arm support, make sure the height is appropriate and choose the arm supports with a wide and soft plate, maybe with a soft cover (7)? In some cases, the arm supports may be set with different heights.
Tray (8): A support from the front, can help the user to better trunk symmetry.
A too upright position may trigger lateral flexion. Secure the active seat tilt with the Comfort Tilt Lock (9) and the active back support position with the Back Angle Control (10).
