Summary
The angle and position of the key, and the shape of the handle can be customized for the user.
Tips for adaptation
-
For people with rheumatoid arthritis (RA), big handles are good in the early stage of the deformation, which lighten the external force to the joint and soften the grip to prevent ulnar deviation of the fingers.
For people who have difficulty in raising their upper limbs due to the contracture of the shoulder/elbow joints, who have difficulty in pronation/supination, or who have ulnar deviation of the wrist, provide a longer handle, which helps the user’s reach, and adjust the angle of the handle and the key between 90° and 135°.
For people with spinal injury, non-slippery surface is useful on the handle because they use the palm or the back of the hand to turn the key.
Even if the user with spinal injury can turn the handle, they may think the handle slippery or find it difficult to press the handle with their hand due to their difficulty in gripping the handle. For that case, it is important to keep a good balance of the handle between the grip side and the other.
