A feedback device for measuring pressure related information, and for providing that information in a way that is useful to the wearer of the device. At least one sensor detects pressure information and transmits at least one pressure information signal to a signal processing subsystem. The signal processing subsystem converts the received pressure information signal into at least one stimulation control signal. The signal processing subsystem then transmits the stimulation control signal to at least one stimulator, which provides stimulation to a wearer of the device reflecting the stimulation control signal received from the signal processing subsystem.

This disclosure relates to a system and method to implement a performance test to help evaluate a patient's neurological and cognitive function.
