Arm Skate

Overview
This is the latest prototype of a device used to support the forearm of a child with limited arm strength and movement. The arm skate is a work in progress and there is likely room for improvement. Two sizes have been created: one for a 5 year old with multiple disabilities and another smaller design for a child in Australia.

Usage
The forearm is placed and strapped into the arm skate. This supports the weight of the arm and allows it to move more freely.
