The world’s only independent alpine ski for athletes with complex physical injury or illness
A skier with limited strength and dexterity due to complex physical injury or illness can smoothly operate the TetraSki safely with a high degree of performance and independence. This is possible because of electric actuators on the TetraSki that provide independent turning and speed variability through the skier’s use of a joystick or sip and puff breath control. The TetraSki does not operate like a motor to push the ski forward or increase speed. The skier’s skills and choices alone determine how fast the ski goes.
The TetraSki was designed at the University of Utah, built by Tetradapt, and operated by TRAILS Adaptive with early and continued support by the Craig H. Neilsen Foundation.
