ASSISTarm was jointly supervised by the Human Centred Design Institute (HCDI) of the Brunel University London in UK and by the Institute of Industrial Technologies and Automation (ITIA) of the National Research Council of Italy.
ASSISTarm is an assistive arm device for children with muscle weakness as a result of Cerebral Palsy, or other neurological conditions. It attaches to a wheelchair, and balances the weight of the user’s arm using spring tension applied through cables to four-bar-linkages. This helps the user to move with very little effort through a sufficient range of motion to carry out activities of daily life such as eating, playing and communicating. The main linkages and pivots are manufactured through 3D printing, which allows the size of the device to be customised to each user. The lower cost of 3D printing compared with metal machining also allows the device to be updated regularly, making it the ideal solution for growing children. Covers on the arm supports and over the mechanisms make the device safer and more comfortable, but can also be personalised to improve the acceptability of the device to each user.
