If you can lift your hips and move to different position, called Horizontal transfer, there wouldn’t be any problem to transfer, but whose who have serious damages on cervical spinal cord and cannot balance the body trunk, or people who are unable to do horizontal transfer because of their physical impairment such as triceps malfunctions need to do vertical transfer which can move the body without raising the hips. However, in order to do the vertical transfer, a certain amount of area between a wheelchair and a bed will be needed, and this could be a problem for some people who cannot get the space.
A tool which can solve this problem is a transfer board (a sliding board).
It would be troublesome tasks for the spine injured to put a transfer board under their hips every time they transfer.
But this board can be set up in 24-hour, and easily attach to a bed as inserting its screws to threaded holes of a fed fence.
I do horizontal transfer and don’t use the board usually. But I’ve once tried this board to transfer. It’s quite stable and had a soft cushion with good padding on its surface, no worry of forming bedsores.
I have many friends who has spine injury. Many of them do not horizontal but vertical transfer, and this kind of board is set up on their beds.
This board can be used for the people who do horizontal transfer. Please challenge the board if you have a caregiver.You may have a risk of falling down to the floor, and must have a caregiver to take care of you.
I think there must be a lot of manufacturers who make this sort of transfer board.
You can consult rehabilitation doctors, wheelchair users who have spine injury and wheelchair makers who have a network to get the information.
