Patent ID: 7478009

Claim:
Apparatus for evaluating spasticity in a movable extremity of a patient comprising: an accelerometer for measuring the acceleration of a point on the extremity during movement thereof in a range of motion of the extremity; a gyroscope for measuring the angular velocity at which the extremity moves in the range of motion; a sensor adapted for measuring the force applied to the extremity as the extremity is moved through the range of motion; a data communication device adapted for transmitting data signals from said accelerometer, said gyroscope, and said sensor; a base on which said data communication device, said accelerometer, said gyroscope, and said sensor are mounted; means for attaching said base to the extremity; a data processor mounted on said base and connected between said accelerometer, said gyroscope, said sensor, and said data communication device for processing the data signals to modify a characteristic of the data signals prior to their being transmitted by said data communication device, said the data processor comprising a first processor adapted for receiving the data signals from said accelerometer, said gyroscope, and said sensor and for performing a first pre-processing operation on said data signals to provide first pre-processed data signals; and a second processor adapted for receiving the first pre-processed data signals and for performing a second pre-processing operation on said first pre-processed data signals to provide second pre-processed data signals.
