We suggest that everyone interested in a custom assistive device from Tetra conduct a little research before submitting a Request For Assistance. Tetra has a policy of not copying products that are commercially available. 

This page is meant as an overview – a place to start researching assistive devices. It is not our intention to link to groups that specialize in specific medical conditions, nor organizations working at the city or provincial/state level, due to the variables involved.
