Abstract: A pronation supination wrist deviator exercise device includes a handle having a proximal portion and a distal portion; a shaft defining a longitudinal axis extending from a proximal end to a distal end; and a head portion having a predetermined weight. The head portion or the handle are mounted for relative movement on the shaft between a first position and a second position. The head portion and the handle define a first distance. The predetermined weight of the head portion represents a first weight. The first weight multiplied by the first distance represents a first effective torque of the device. When the distance between the head portion and the distal portion of the handle is changed to at least a second distance, the first weight multiplied by the second distance represents at least a second effective torque of the device.

Abstract: A force dynamometer includes at least one plate, a controller with a memory and at least one force sensing resistor that senses a force exerted on the one or more plates. The controller receives a signal indicating magnitude of the force and transmits a signal to at least one color variable light emitting diode (LED) to change color of the color variable LED in response to the force sensing resistor changing magnitude of the force signal transmitted to the controller. The controller may transmit a signal to one or more piezoelectric sensors such that the controller controls intensity of vibrations and/or magnitude of frequency of the vibrations of the one or more piezoelectric sensors. A force dynamometer system includes a computing device that displays or controls speed of a variable motion speed image or object or displays or controls a direction controllable image or object via the force dynamometer.

Abstract: A therapeutic hand-held exercise device includes a pair of movable members that each define a handle portion and an end effector portion. The movable members are pivotably connected for relative pivotal movement between a first position and a second position. The handle portion of one of the movable members defines at least one flexible member engaging post. The end effector portion of the other movable member defines at least one flexible member engaging post such that the flexible member engaging posts can receive a common flexible member. The flexible member engaging posts are joined via a first common flexible member and other flexible member engaging posts are joined via a second common flexible member. The common flexible members may each exhibit a tensile strength that provides resistance to movement which either differs from or is equal to the tensile strength of the other common flexible member.

Abstract: A resistive therapeutic device is disclosed such that upon a user applying torque a controller emits a signal to an electromagnetic resistance generating member. The controller detects a maximum torque applied by a user detects if the maximum torque applied by a user is less than or equal to a resistance setting. The torque resistance is variable from a neutral position to a maximum position, and the controller increases the resistance setting as a user moves a torque application member in a direction away from the neutral position that represents an increase in torque applied by the user. A control and user interface for a resistive therapeutic device includes an evaluation display of torque strength applied and displays an angle of rotation clockwise or counterclockwise directions ranging from 0 degrees to 360 degrees and a count of repetitive times a user has rotated at least 360 degrees in either direction.

Abstract: A compression-resistant device includes least one pair of first and second opposing jaw members having respective engaging surfaces for movement from an open position receiving an object and a closed position engaging the object. A manual compression surface enables a user to manually apply pressure to urge the engaging surfaces from one of the closed position towards an open position or from the open position towards the closed position. At least one resistance member interfaces with the first and second opposing jaw members to resist pressure manually applied by a user urging the engaging surfaces from the closed position towards the open position or from the open position towards the closed position. The manual compression surface includes projections such that manually applied pressure forms at least one aggravated area on a finger surface of the user to initiate a callus. A corresponding method of operating the device is also disclosed.
