Sensing systems and methods for monitoring gait dynamics
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.
1. A system for providing artificial proprioceptive feedback from a prosthetic foot, the system comprising:
a prosthetic foot operatively coupled to an amputated lower limb of a user;
a sensor system configured to be placed on the prosthetic foot, the sensor system comprising at least one sensor configured to measure a characteristic of the prosthetic foot;
a processor configured to process data from the at least one sensor to determine a condition of the prosthetic foot; and
a user interface configured to provide artificial proprioception to the user based on the data, the user interface configured to be worn by the user at a location on the user's body remote from the prosthetic foot.
2. The system of claim 1 , wherein the user interface is configured to receive signals from the processor via wireless communication.
3. The system of claim 1 , wherein the user interface is configured to provide artificial proprioception to the user via non-electrical sensory feedback.
4. The system of claim 1 , wherein the condition of the prosthetic foot is a stage of a gait cycle of the user.
5. The system of claim 1 , wherein the processor is a remote processing unit.
6. The system of claim 1 , wherein the processor is configured to determine the condition of the prosthetic foot by determining whether the data is inside or outside of a predetermined range or exceeds a threshold value.
7. The system of claim 1 , wherein the sensor system is located on a top surface of the prosthetic foot.
8. A system for providing artificial proprioceptive feedback from a prosthetic foot, the system comprising:
a sensor system configured to be placed on a prosthetic foot operatively coupled to an amputated lower limb of a user, the sensor system comprising at least one sensor configured to measure a characteristic of the prosthetic foot;
a processor configured to process data from the at least one sensor to determine a condition of the prosthetic foot; and
a user interface configured to provide artificial proprioception to the user based on the data, the user interface configured to be worn by the user at a location on the user's body remote from the prosthetic foot.
9. The system of claim 8 , wherein the user interface is configured to receive signals from the processor via wireless communication.
10. The system of claim 8 , wherein the user interface is configured to provide artificial proprioception to the user via non-electrical sensory feedback.
11. The system of claim 8 , wherein the condition of the prosthetic foot is a stage of a gait cycle of the user.
12. The system of claim 8 , wherein the processor is a remote processing unit.
13. The system of claim 8 , wherein the processor is configured to determine the condition of the prosthetic foot by determining whether the data is inside or outside of a predetermined range or exceeds a threshold value.
14. The system of claim 8 , wherein the sensor system is located on a top surface of the prosthetic foot.
