Abstract
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.
Core Innovation
The invention relates to a wearable position therapy device (PTD) and associated methods for providing and assessing position therapy for a user. The device collects positional data via a position detector while the user is wearing the wearable position therapy device, and the positional data are used to determine the user’s positions over a time period. When it is determined that the user is in a supine position, the device provides feedback to influence the user to change to a non-supine position.
The invention includes providing an assessment of the efficacy of the position therapy based on a measure of time spent in the supine and non-supine positions and at least one additional measure. The assessment can be based on information derived from the positional data and, in some implementations described in the document, also uses additional measures associated with the user’s sleep-disordered breathing context such as snoring-related audio measures. An assessment workflow can be performed as part of the device’s system or by one or more software modules.
The invention also includes adaptive delivery of feedback while providing position therapy. In one aspect, the device adaptively delivers feedback by increasing a number of feedback generators used until the user changes to a non-supine position, where the feedback generators comprise a plurality of haptic motors. The document further describes use of stored treatment/compliance data and transferring data to an external computer system and/or web portal to generate reports, including baseline recording for before/after comparison.
Claims Coverage
The partial document provides three independent claims that cover three inventive features: determining supine versus non-supine positions from positional data collected by a wearable device, providing feedback when supine to influence a change to non-supine position, and assessing efficacy based on supine/non-supine time together with at least one additional measure.
Efficacy assessment using supine/non-supine time and an additional measure
Providing position therapy to a user while the user is wearing a wearable position therapy device; collecting positional data via a position detector while the user is wearing the wearable position therapy device; based on the positional data, determining positions of the user over a time period; when it is determined that the user is in a supine position, by a feedback generator of the wearable position therapy device, providing feedback to influence the user to change to a non-supine position; and providing an assessment of the efficacy of the position therapy, based on a measure of time spent in the supine and non-supine positions and at least one additional measure.
Adaptive feedback delivery by increasing a number of feedback generators until non-supine
Providing position therapy to a user while the user is wearing a wearable position therapy device; collecting positional data via a position detector while the user is wearing the wearable position therapy device; based on the positional data, determining positions of the user over a time period; when it is determined that the user is in a supine position, adaptively delivering feedback by increasing a number of feedback generators used until the user changes to a non-supine position; wherein the feedback generators comprise a plurality of haptic motors.
System with wearable position therapy device and software modules for assessment
A system comprising a wearable position therapy device comprising a position detector and a feedback generator, wherein the wearable position therapy device provides position therapy to a user while the user is wearing the wearable position therapy device by collecting positional data via the position detector while the user is wearing the wearable position therapy device, based on the positional data determining positions of the user over a time period, and when it is determined that the user is in a supine position, by the feedback generator providing feedback to influence the user to change to a non-supine position; and one or more software modules that, when executed by a processor, provide an assessment of the position therapy, based on a measure of time spent in the supine and non-supine positions and at least one additional measure.
The claim coverage centers on determining supine versus non-supine positions from positional data collected by a wearable device, providing feedback when supine to influence a change to non-supine position, and assessing efficacy based on supine/non-supine time together with at least one additional measure. The provided claim text also indicates adaptive escalation of feedback using a plurality of haptic motors and software modules for assessment.
Stated Advantages
Provides an assessment of the efficacy of the position therapy based on a measure of time spent in the supine and non-supine positions and at least one additional measure.
Adaptively delivers feedback by increasing a number of feedback generators used until the user changes to a non-supine position.
Documented Applications
Treating sleep-disordered breathing such as obstructive sleep apnea (OSA) using a wearable position therapy device that detects positional state and provides feedback.
Rehabilitation training and positional avoidance during pregnancy and bed-rest, as described in the document’s embodiments.
