Adjust Etac Prio for a Large Upper Body

A large upper body that is poorly supported can result in trunk flexion and respiratory difficulties. Evaluate both the active and resting position carefully.

Active Position
Seat depth: The user may require a longer seat depth (1) due to a voluminous trunk. Set the back support in position 3, which is most rear. This also redistributes weight away from the front castors. For users with leg amputation or very slim legs, the weight distribution may require that the the seat depth primarily is adjusted from the front (2), with the back support mounted in position 1 or 2. Back support: Be generous with the back strap adjustment in level with the buttocks. Aim for extension in thorax and adjust the Dynamic Pelvic Support (3) in the level of PSIS. This will facilitate the diaphragm to expand which is necessary for a functional breathing. The active position is a combination of seat to back angle and seat tilt. Secure the position with the Back Angle Control (4) and Comfort Tilt Lock (5).


Resting Position
Prioritize a relaxed breathing pattern and comfort. Maybe the difference between the active and relaxed position isn´t so big?
Tilt and Recline Positions: A large upper body changes the weight distribution which can affect the chair´s stability. So even if the person can use maximum tilt and recline, check the chair stability and use Gas Piston Clips (6) to reduce the maximum tilt and recline position. Another possibility is to move the rear wheels backwards. But consider that even if the person is not propelling, this will make the chair heavier to push. Anti-tippers: Always check adjustment. Amputee Support (7): For a below knee amputation. Evaluate carefully how much knee extension the user can tolerate. Don´t try to force the knee into extension.

 

1. Rear Seat Depth Setting
The back support can be mounted in three different depth positions. The further back the more of the user weight will come over the rear wheels which makes the chair easier to propel and push.

2. Front Seat Depth Adjustment
The front seat plate can be adjusted 7 cm (3") in depth. Always consider the rear seat depth adjustment first.

3. Dynamic Pelvic Support
Automatically relieves the tension in the reclined position and re-tightens in the active position.Adjust the height to the level of PSIS.

4. Back Angle Control
By adjusting the length of the strap, the active back support setting can be controlled. The back will always stop at the preset angle. Note: The Back Angle Control will be available during 2019.

5. Comfort Tilt Lock
Stops the tilt position at a preset angle. Choose between: 0°, 4°, 8° or 12° seat tilt. The position can be changed by moving the locking device on the gas piston.

6. Gas Piston Clips
Each clip reduces the angling with approximately 2°. Can be used for both tilt and recline gas pistons. Easy to attach, easy to remove.

7. Amputee Support
Provides a comfortable support for a amputated leg. Adjustable in height depth, angle and sideways. Also available with hygienic cover.
