People with disabilities due to spinal cord injuries are a burden to people and families who cannot live their daily lives. The development of assistive technology has played an important role in helping people with paralysis. This will improve their ability to manage their environment, help them find work, reduce the number of family workers and reduce healthcare costs. Tongue propulsion systems are one of the assistive technologies that help people with severe disabilities easily take control of their lives. The tongue is an appropriate organ for operating assistive technology.
