One-Handed Mahjong (DL-20)

For (With Whom)

People who have difficulty playing mahjong with both hands, specifically those with paralysis or other impairments of the hands and fingers.

Why

A person with paralysis in both upper limbs as an after-effect of cervical myelopathy told us that they wanted to play mahjong at their day service, but the automatic mahjong table was broken and they could not stack tiles with one hand, and that they would not play because asking for help would be a nuisance. So we decided to make a tool that lets them stack tiles by themselves even with one hand.

How

During a home-visit rehabilitation session, when we asked about leisure activities, we learned that the person used to play mahjong but had recently given up. Since we had already been assessing and intervening on their hand and finger function, we designed and made a tool they could use with their remaining function.

Outcome

They can now stack mahjong tiles in two rows with one hand, and enjoy mahjong at the day service.
