Abstract

An apparatus for performing a remote test of range of motion of a person operating a user device includes a transceiver, a processor, and a display. The transceiver is configured to transmit a link to the user device and to receive motion data from the user device. The processor is configured to calculate in real time, based on the motion data, the position of the user device to enable real-time display to a test provider of the performance of the test and to determine in real time the quality of the test. The display is configured to show in real time a continuous indication of the performance of the test and quality results of the test. A method for performing a remote test of range of motion of a person operating a user device is also described and claimed.

Claims (28)

1. An apparatus for performing a remote test of range of motion of a person operating a user device, comprising:

a transceiver configured to transmit a range-of-motion test link to the user device and to receive motion data from the user device, the user device comprising a sensor that generates the motion data and a second transceiver to communicate with the transceiver;

a processor configured to calculate in real time, based on the motion data, the continuous position of the user device to enable real-time display to a test provider of the performance of the test and to determine in real time whether the test is performed correctly based on correlating angle measures among multiple frame axes; and

a display configured to show in real time a continuous indication of the performance of the test and whether the test is performed correctly.

2. The apparatus of claim 1 , wherein the indication of the performance of the test comprises motion of the user device.

3. The apparatus of claim 1 , wherein the indication of the performance of the test comprises a three-dimensional depiction of the user device.

4. The apparatus of claim 1 , wherein the indication of the performance of the test comprises a continuous display of angle of motion.

5. The apparatus of claim 1 , wherein the motion data are generated using an accelerometer in the user device.

6. The apparatus of claim 1 , wherein the test is an extension-flexion test of the person's wrist.

7. The apparatus of claim 1 , wherein the test is a pronation-supination test of the person's wrist.

8. The apparatus of claim 1 , wherein the test is a radial-ulnar deviation test of the person's wrist.

9. The apparatus of claim 1 , wherein the position of the user device is calculated using a rotation matrix.

10. The apparatus of claim 1 , wherein the user device displays real-time data about the test.

11. A method for performing a remote test of range of motion of a person operating a user device, comprising:

transmitting, with a transceiver, a range-of-motion test link to the user device;

receiving motion data from the user device, the user device comprising a sensor that generates the motion data and a second transceiver to communicate with the transceiver;

calculating in real time, based on the motion data, the continuous position of the user device to enable real-time display to a test provider of the performance of the test;

determining in real time whether the test is performed correctly based on correlating angle measures among multiple frame axes; and

displaying in real time a continuous indication of the performance of the test and whether the test is performed correctly.

12. The method of claim 11 , wherein the indication of the performance of the test comprises motion of the user device.

13. The method of claim 11 , wherein the indication of the performance of the test comprises a three-dimensional depiction of the user device.

14. The method of claim 11 , wherein the indication of the performance of the test comprises a continuous display of angle of motion.

15. The method of claim 11 , wherein the motion data are generated using a gyroscope in the user device.

16. The method of claim 11 , wherein the test is an extension-flexion test of the person's wrist.

17. The method of claim 11 , wherein the test is a pronation-supination test of the person's wrist.

18. The method of claim 11 , wherein the test is a radial-ulnar deviation test of the person's wrist.

19. The method of claim 11 , wherein the position of the user device is calculated using a rotation matrix.

20. The method of claim 11 , wherein the user device displays real-time data about the test.
