Trainers may also incorporate rotary encoders, accelerometers and torque sensors to enable interface with computer data acquisition systems (DAQ) for analysis of propulsion kinematics.
Calculation of rolling resistance between the tire & contact roller interface, axle friction, and inertial characteristics of wheelchair wheels and flywheels may be used in determination of stationary propulsion dynamics.
[5] The last patent is being commercialized under the trademark Trekease, designed to serve as an acronym for Translational & Rotational Equivalent Kinetic Energy Aerobic Stationary Exertainment and as a homonym for Trekkies – fans of Star Trek.
Arcade game software and clinical data acquisition use were first introduced by the Veterans Administration's WAFT as a means of promoting stationary wheelchair propulsion as a beneficial aerobic exercise.
[ergonomics] Utilizing lever propulsion technologies on a wheelchair trainer equipped with flywheel and resistance enables one to engage in an activity similar to rowing with all its associated health benefits and risks.
