Abstract
A rehabilitation device for exercising a human appendage comprises a housing defining a reservoir and a thermally controllable viscous fluid contained within the reservoir, the thermally controllable viscous fluid having a temperature and a viscosity. The thermally controllable viscous fluid experiences an apparent change in viscosity when exposed to a change in temperature. A heating apparatus is provided for increasing the temperature of the thermally controllable viscous fluid, and a cooling apparatus is provided for decreasing the temperature of the thermally controllable viscous fluid. A temperature control apparatus is provided for selectively increasing or decreasing the temperature of the thermally controllable viscous fluid and thereby decreasing or increasing the viscosity of the thermally controllable viscous fluid.
