Abstract

The present technology describes various embodiments of systems and methods for remote monitoring of exercise performance metrics. In several embodiments, for example, a method of evaluating an exercise performed by a patient includes providing the patient with a pre-recorded avatar showing an exemplary instance of a prescribed exercise. The method further includes sensing the patient'"'"'s movement during an exercise session and generating a real-time avatar based on the sensing. The pre-recorded avatar can be overlaid with the real-time avatar. The graphic overlay readily shows the patient whether and where his motion and/or body position deviate from the prescribed exercise. The overlay can be made in real time. In several embodiments, the patient'"'"'s independently-recorded avatar and/or performance metrics are transmitted to the exercise prescriber to monitor the fidelity with which the patient is able to reproduce the exercise outside the prescriber'"'"'s supervision.

Claims

1. A method of evaluating an exercise, the method comprising:

pre-recording a three-dimensional avatar representing an exemplary instance of a prescribed exercise;

generating a three-dimensional real-time avatar of a patient performing the prescribed exercise; and

graphically comparing the pre-recorded avatar and the real-time avatar.

2. The method of claim 1 wherein pre-recording an avatar comprises generating the pre-recorded avatar in the presence of an exercise prescriber.

3. The method of claim 1 wherein graphically comparing the pre-recorded avatar and the real-time avatar comprises overlaying the pre-recorded avatar with the real-time avatar.

4. The method of claim 3, further comprising transmitting the overlaid pre-recorded avatar and real-time avatar to at least one of an exercise prescriber or health care provider.

5. The method of claim 3 wherein overlaying the pre-recorded avatar with the real-time avatar comprises overlaying the avatars as the real-time avatar is being generated.

6. The method of claim 1, further comprising indicating deviation between the pre-recorded avatar and the real-time avatar.

7. The method of claim 6 wherein indicating deviation comprises providing at least one of a visual or audio alert.

8. The method of claim 6 wherein indicating deviation comprises indicating a plurality of regions on the real-time avatar that fall outside a pre-determined acceptable trajectory of the pre-recorded avatar at one or more time points during the exercise.

9. The method of claim 8 wherein indicating a plurality of regions on the real-time avatar that fall outside a pre-determined acceptable trajectory of the pre-recorded avatar comprises indicating an anatomical landmark on the real-time avatar that falls outside an acceptable angle or distance from a corresponding anatomical landmark on the pre-recorded avatar.

10. The method of claim 8, further comprising graphically displaying the acceptable trajectory overlaid on at least one of the real-time avatar or the pre-recorded avatar.

11. The method of claim 6, further comprising generating a report regarding the deviation and transmitting the report to at least one of an exercise prescriber or health care provider.

12. The method of claim 11 wherein transmitting the report to an exercise prescriber or health care provider comprises transmitting the report in a format that allows for selection of the deviation in the report and, upon selection, displaying a recording of the real-time avatar that corresponds to the deviation.

13. A method of exercise instruction, the method comprising:

providing a patient with a pre-recorded avatar;

sensing the patient'"'"'s movement during an exercise session;

generating a real-time avatar based on the sensing; and

displaying the pre-recorded avatar overlaid with the real-time avatar.

14. The method of claim 13, further comprising identifying deviation between the real-time avatar and the pre-recorded avatar.

15. The method of claim 14, further comprising modifying the exercise regime in response to at least one of the deviation or a patient condition.

16. The method of claim 15, further comprising providing the patient with an updated pre-recorded avatar based on the modifying.

17. The method of claim 14 wherein identifying deviation between the real-time avatar and the pre-recorded avatar comprises identifying deviation between an anatomical landmark on the real-time avatar and a corresponding anatomical landmark on the pre-recorded avatar.

18. The method of claim 13 wherein sensing the patient'"'"'s movement during an exercise session comprises sensing the patient'"'"'s movement outside the presence of an exercise prescriber.

19. A system for tracking exercise accuracy, the system comprising:

a motion or body sensing device configured to detect a patient'"'"'s body position and generate movement data based on the patient'"'"'s body position over time;

a physical computer-readable storage medium having stored thereon instructions executable by a device to cause the device to generate an avatar recording based on the movement data; and

a display device configured to display the avatar recording overlaid with an exemplary exercise avatar.

20. The system of claim 19, wherein the instructions further cause the device to detect deviation between the stored avatar and the exemplary exercise avatar.

21. The system of claim 20 wherein the instructions further cause the device to generate a report including at least one of the movement data, the deviation, or the avatar recording.

22. The system of claim 21, further comprising a transmitter configured to transmit the report to at least one of an exercise prescriber or health care provider.

23. The system of claim 22, further comprising a computing device remote from the physical computer-readable storage medium and configured to receive the transmitted report and display the report to the exercise prescriber or health care provider.
