Wheelchair trainer : ウィキペディア英語版 | Wheelchair trainer A wheelchair trainer or wheelchair treadmill is an apparatus that allows a manual wheelchair user to simulate linear (translational) travel while remaining stationary in a manner similar to an ambulatory person walking or running on a treadmill or a cyclist pedaling a bicycle on a bicycle trainer. The rear wheelchair wheels are placed in contact with vertical or horizontal rollers which may also be attached to flywheels, mechanical resistance or braking mechanisms, motors and various speed and force sensors. Flywheels may be sized to provide a user of a certain mass with a rotational inertia equivalent to their translational (linear) inertia in order to more realistically approximate actual wheelchair propulsion. Wheelchair trainers having independent contact rollers permit simulated directional travel (omnidirectional treadmill). Trainers may also incorporate rotary encoders, accelerometers and torque sensors to enable interface with computer data acquisition systems (DAQ) for analysis of propulsion kinematics. A quadrature rotary encoder or hall effect sensor can be implemented to provide sufficient speed and direction information to enable virtual navigation interface with video games in a manner similar to using a joystick or gaming console. 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.() ==History== The United States Department of Veterans Affairs (VA) has substantially invested in decades long research and development for two wheelchair trainer devices: the Wheelchair Aerobic Fitness Trainer (WAFT),〔 and GameWheels. The history of wheelchair trainer development may be summarized from the 10 patents issued by the United States Patent and Trademark Office for stationary wheelchair trainers/treadmills/ergometers/dynamometer/simulators issued from 1980 to 2009.〔
