Qualitative assessment of Tongue Drive System by people with high-level spinal cord injury

This study reports on a qualitative assessment of the Tongue Drive System (TDS) as an assistive technology for individuals with high-level spinal cord injury. The study sought participants' opinions on the acceptability and usability of TDS compared to other assistive technologies.

  2. Aim • Report results of qualitative study on potential Tongue Drive System (TDS) end users with high-level spinal cord injury, seeking their opinions about acceptability of this new assistive technology. • Relevance • TDS is a minimally invasive, wireless, and wearable assistive technology that enables people with severe disabilities to control their environments using voluntary tongue motions.

  3. Method • Participants with high-level spinal cord injury (C5 and above) each received a magnetic tongue piercing and used the TDS for 6 wk. • We used 2 questionnaires (after-scenario and poststudy) to evaluate tongue-piercing experience and TDS usability vs. sip-and-puff and users’ current assistive technology.

  4. Results • 73% of participants were positive about keeping magnetic tongue-barbell to use the TDS. • All were satisfied with the TDS performance. • Most said they were able to do more things using TDS than their current assistive technologies.

  5. Conclusion • We have developed a wireless and wearable tongue-operated assistive technology to provide reliable, easy, and effective access to PCs, power wheelchairs, smartphones, and other devices in users’ environments. • Participants were open to using the TDS in their daily lives.
