Study: NCT01124292

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Tongue Piercing
Description: Subjects brush their teeth, and then swish and spit with chlorhexidine mouthwash for 30-60s. Subjects would be placed in a semirecumbent position in a procedure chair. After marking the piercing site using a sterilized surgical marking pen the protruded tongue would be pierced. Anesthesia may be used during the piercing at the discretion of the operator and the subject. A sterilized titanium or surgical grade stainless steel piercing tongue stud would be placed in an appropriate position on the tongue to minimize complications from the piercing but also facilitate good functionality of the TDS.

Group type: EXPERIMENTAL
Intervention: Usability assessment
Description: Computer access: Subjects wear the TDS and get trained. Then they sit 1.5 m from a 22 LCD monitor. Then they use TDS to conduct several tasks using their tongues, such as clicking on target objects and navigating through on-screen maze, while the computer registers their tongue commands and measures their performance.~Wheelchair control: Subjects wear the TDS and use it to drive an electrically powered wheelchair through an obstacle course using their tongues. The operator measured the time it takes for the subjects to drive through the course as well as the number of collisions.
