Who

Why

After such incidents, most patients struggle to perform daily tasks such as eating and drinking, and despite rehabilitation training, many require additional help to gain independence in these areas.

What

How

An arm sling mechanism that hangs from a pole positioned above the wheelchair to neutralize gravity.
