1. A system for evaluating a prosthetic or orthotic device, comprising:
- a prosthetic or orthotic foot device comprising one or more elongate members configured to bend in response to an interaction of the device with a support surface upon which a user of the device is moving;
at least one sensor associated with the one or more elongate members, the sensor configured to bend with the one or more elongate members in use and measure bending of the one or more elongate members during the user'"'"'s gait;
a processor configured to receive data from the sensor and determine a condition of the device using said sensor data, the processor configured to determine a condition of the device by determining whether the data is inside or outside of a predetermined range or exceeds a threshold value; and
an interface configured to provide information regarding the condition of the device.

Abstract
Systems and method for monitoring gait dynamics are disclosed. The performance of an orthotic or prosthetic device or other device associated with a limb may be measured based on the resistance of a bending sensor. Data from the sensors is gathered or processed, particularly for purposes of alignment, safety, failure, usage, selection, and artificial proprioception. Information relating to the device may be outputted visually or auditorily to an individual.

17. A system for providing artificial proprioceptive feedback from a prosthetic device, comprising:
-
a prosthetic device configured to be associated with a user'"'"'s limb; a sensor associated with the device, the sensor configured to measure a performance characteristic of the device; and means for communicating sound corresponding to the performance characteristic, wherein the sound varies during use of the device, and a sound pattern corresponds to a gait characteristic of the user to provide artificial proprioception to the user of the device. - View Dependent Claims (18, 19, 20)
