Patent Images
1. A system for providing biofeedback corresponding to a gesture of a user, comprising:
- a sensor assembly for detecting muscular activity of a subject and providing sensor signals indicative of the detected muscular activity wherein the sensor assembly comprises a plurality of force sensors spaced apart from one another;
a processor operable to process the sensor signals, wherein the processor is operable in a set up mode and a therapy mode,wherein in the set-up mode the processor is operable to receive the sensor signals from the sensor assembly produced by volitional movements by the subject and calculate a template of predetermined values corresponding to the sensor signals received from the sensor assembly indicative of the muscular activity of the subject during the set-up mode; and
wherein in the therapy mode the processor is operable to receive the sensor signals from the sensor assembly, compare the sensor signals against the template of predetermined values and provide an output signal based on the variation between the received sensor signals and the predetermined values, wherein the output signal can be used to provide feedback to the user.

Abstract
A gesture recognition biofeedback device is provided for improving fine motor function in persons with brain injury. The system detects a physical characteristic of the patient and provides feedback based on the detected characteristic. For instance, the system may detect surface muscle pressures of the forearm to provide real-time visual biofeedback to the patient based on a comparison of the detected muscle pressure and predefined values indicative of appropriate motor function.
