The WAFT is not available for sale at this time. There are eight prototypes in use, all owned by the Veterans Administration and located at various medical centers around the US. Engineering is currently underway to improve the areas of weight, size, and cosmetics, and most importantly to upgrade the software. The new design will allow some flexibility in upfitting to accommodate institutional needs (hospitals and rehab centers), or commercial needs (health clubs, recreation centers, etc.). The new version will be available about 12 months from now.

The Wheelchair Aerobic Fitness Trainer (WAFT) is a computerized treadmill that allows a person in a wheelchair the freedom to exercise, train for sports or competition, undergo rehabilitation or stress testing, or engage in recreational/educational activities.

An early version of the WAFT was patented in 1990 by Drs. Ed Langbein and Lutz Kynast at the Hines VA Hospital, Hines, IL. Still not satisfied that desired performance factors were achieved, the VA decided to put out bids for assistance from private engineering firms.
