Technical Field
The present technology relates to software applications for connected devices. The present technology relates more specifically, but not exclusively, to an application capable of assessing a user's real-time fall risk when installed on a commercially available mobile device equipped with inertial measurement capabilities, with internet and/or cellular connectivity and voice communication technology.
Background
The approaches described in this section could be pursued, but are not necessarily approaches that have been previously conceived or pursued. Thus, unless otherwise indicated, it should not be assumed that any of the approaches described in this section qualify as prior art merely by virtue of their inclusion in this section.
In response to the numerous risks associated with aging, and the fact that the U.S. population is rapidly aging, efforts to maintain independence have led to the development of several applications that focus on various aspects of health monitoring. Most of these applications have been developed in such a way that they include the ability to monitor biological factors, e.g.; blood pressure, heart rate, blood glucose level, and/or sleep. While there is evidence that these bio-signals are associated with overall health and continuous monitoring of, for example, these parameters may help improve health, currently available health applications do not provide the ability to continuously monitor the ability of a user to generate motion. Additionally, these current health monitoring applications are typically not self-contained and many times require hardware other than the hardware on which the application is installed. The present technology provides a self-contained integrated method of assessing a user's mobility and provides a non-invasive method for directly monitoring and identifying functional capability degradation. The results of these key motion assessments are easily accessible by the user and displayed on the user's mobile device in various formats.

In various embodiments, performing a longitudinal body movement assessment analysis comprises: receiving, from a cloud-based specification data store, a threshold of a predetermined change in body movement associated with a domain; comparing the user's assessment of body movement to a predetermined threshold of change in body movement; based on the comparison, determining that the body movement assessment exceeds a predetermined threshold of body movement variation; and displaying a longitudinal mobility assessment for the user if the body movement assessment exceeds a predetermined threshold of body movement change.
Example 1.
Fig. 4A shows the results of an inertial data processing algorithm 200 for analyzing an assessment 400 of standing chair based clinical mobility, in accordance with embodiments of the present technique. For example, the functional test may be the ability of the user 110 to complete a chair standing. This particular test area provides valuable insight into the lower limb muscular strength of the user 110. One particular test, i.e., 30 seconds of chair standing, may be evaluated remotely by application 155. To accomplish this, the user 110 assumes a seated position in a standard chair, opens an application 155 (e.g., an e-caregiver application) and selects a corresponding test from a drop-down menu (e.g., based on an assessment of clinical mobility while the chair is standing). After the test selection, the inertial measurement unit 130 of the mobile device 120 is activated and begins collecting inertial data for the user 110. After the last 5 seconds, the user 110 begins the chair standing test and repeats as many sit-to-stand movements as possible immediately standing to sitting within the specified time. As depicted in fig. 4A, the vertical acceleration signal may be used to evaluate the number of repetitions completed during the test, which is a standard clinical variable evaluated during the test. The evaluation of the number of repetitions completed is achieved by applying a signal segmentation that separates the signal into different segments based on a quantifiable peak of the vertical acceleration value and the application of a simple counting function that determines the number of independent segments derived during processing. For example, a signal segment 405 of a plurality of signal segments is shown in fig. 4A.
Example 2.
FIG. 4B depicts the results of the inertial data processing algorithm 200 for analyzing an
In various embodiments, the systems and methods of the present technology described herein are capable of performing the same assessment as a clinician as desired in various embodiments. Thus, the user 110 assumes a seated position in a standard chair, opens an application 155 (e.g., an e-caregiver application), and selects a clinical mobility-based assessment (i.e., a timed-rise and walk clinical mobility-based assessment) from a drop-down menu on the mobile device 120. After the test selection, the inertial measurement unit 130 is activated and begins collecting inertial data for the user 110. After the last 5 seconds, the user 110 performs the timed rise and walk test all the way through. After returning to the sitting position, the user selects the end test icon to terminate the collection of inertial data. With the timed rise and walk test complete, the signal segmentation algorithm segments the inertial data into a standing
Example 3.
Another common functional test utilized in an elderly care services environment is a postural stability test. The postural stability test requires the user 110 to maintain a static stance for a period of time during which postural sway measurements are collected. As the postural stability test is completed, the clinician will typically record the observed stability of the user 110 completing the postural stability test as well as various acceleration magnitudes indicative of the postural sway. Also, the systems and methods of the present technology, including the application 155 (e.g., an e-caregiver application), are able to perform the same assessment as the clinician, as desired. Thus, the user 110 assumes a standing posture, opens an application 155 (e.g., an e-caregiver application) and selects a posture stability test from a drop-down menu. Upon selection of the postural stability test, the inertial measurement device 130 in the mobile device 120 is activated and begins collecting inertial data for the user 110. After the last 5 seconds, user 110 performs the gesture stability test for a period of time specified by application 155. As the postural stability test is completed, the inertial data of the user 110 is processed and converted into anteroposterior, lateral and composite magnitudes (i.e., accelerometer data) and angular motion magnitudes about anteroposterior, lateral and transverse axes (i.e., gyroscope data). The accelerometer data and gyroscope data are analyzed to quantify the amount of sway along and around each body axis, which can be used as an indicator of the overall static stability and potential fall risk of the user 110.
