Systems and methods for controlling position
Systems and methods for assessing compliance with position therapy. In an embodiment, position therapy is provided to a user while the user is wearing a position therapy device. The position therapy comprises, by the device, collecting positional data, determining positions of the user over a time period based on the positional data, and, when it is determined that the user is in a target position, providing feedback to the user to influence the user to change to a non-target position. In addition, the device stores a duration of use in its memory. The duration of use indicates a duration that the user has used the wearable position therapy device in each of one or more positions. An assessment of the user's compliance with the position therapy is then provided based, at least in part, on the duration of use.

7. The method of claim 5 , further comprising the wearable position therapy device collecting the breathing pattern of the user and wherein the interruptions in sleep are determined based on the collected breathing pattern of the user.
8. The method of claim 4 , further comprising capturing audio data and wherein the at least one additional measure comprises a snoring frequency.
9. The method of claim 8 , wherein the report is based on a relationship between one of snoring frequency and snoring magnitude during the time spent in the target and non-target positions.
10. The method of claim 1 , further comprising, by the wearable position therapy device, transmitting information to an external system which provides an assessment of the efficacy of the position therapy based on the time spent in the target and non-target positions, wherein the time spent in the target and non-target positions is derived from the transmitted information.
11. The method of claim 10 , wherein generating the report of the position therapy comprises, by the wearable position therapy device, collecting positional data, without applying feedback, to generate baseline data, wherein the report of the position therapy is based on a comparison to the baseline data.
12. The method of claim 11 , wherein the comparison to the baseline data comprises determining a difference between an amount of time spent in the target position, with application of the feedback, and an amount of time spent in the target position, without application of the feedback.
13. The method of claim 11 , wherein the comparison to the baseline data comprises determining a difference between a number of attempts to be in the target position, with application of the feedback, and a number of attempts to be in the target position, without application of the feedback.
14. The method of claim 1 , wherein providing feedback comprises adaptively increasing the feedback until the user changes to the non-target position.
15. The method of claim 14 , wherein increasing the feedback comprises one or more of increasing an intensity of the feedback, increasing a length of the feedback, and decreasing a duration between feedback events.
16. The method of claim 1 , further comprising, by the wearable position therapy device, saving an action history to memory, wherein the action history comprises one or more of when a battery of the wearable position therapy device has been charged, when the wearable position therapy device has been powered on or off, and when the wearable position therapy device has started and stopped recording positional data.
17. The method of claim 1 , further comprising delaying the feedback for at least a predetermined or configurable time period.
18. The method of claim 17 , further comprising delaying the feedback for longer than the time period when movement is detected after the time period has elapsed.
19. The method of claim 17 , further comprising delaying the feedback for longer than the time period when snoring is not detected after the time period has elapsed.
20. The method of claim 1 , wherein the feedback is provided immediately after a position change to the target position.

22. The method of claim 21 , wherein the audio feedback comprises a voice message or audio pattern.
23. The method of claim 1 , wherein the position detector is a remote sensor that communicates wirelessly with a transceiver of the wearable position therapy device, and wherein a processor of the wearable position therapy device performs the determination of whether the user is in the target position or one or more non-target positions, and, when it is determined that the user is in the target position, generates a control signal for the feedback generator.
24. The method of claim 1 , wherein the at least one additional measure comprises a percentage of time the user was target.
25. The method of claim 1 , wherein the wearable position therapy device comprises a housing that contains a transceiver, a processor that generates a control signal for the feedback generator, and a memory that stores position and feedback information, and wherein the position detector comprises a remote sensor outside the housing that wirelessly transmits the positional data to the transceiver within the housing.
