A method for detecting a user's intent in an adaptive lower limb device includes providing the adaptive lower limb device. The lower limb device includes a device control unit. The device control unit includes activity controllers and at least one accelerometer. The acceleration features are measured via the at least one accelerometer. The measured acceleration features are determined whether they correspond to a tapping movement initiated by a user with an intent to switch from a first one of the plurality of activity controllers to a second one of the plurality of activity controllers. If the measured accelerating features correspond to the tapping movement, the control unit of the adaptive lower limb device is switched from the first one of the activity controllers to the second one of the activity controllers.

Patient sleep is staged using personalized circadian models built with data collected by wearable devices over daytime and nighttime hours, thus capturing a patient's personal circadian rhythms. The circadian model is used to identify sleep intervals in incoming nightly data for the patient. The identified sleep intervals are analyzed by the machine learning system which stages epochs of sleep. Methods include receiving patient heart rate data from over a plurality of circadian cycles; creating a circadian model for the patient with a defined operation for applying sleep labels to new data from the wearable device; applying the circadian model to nightly test data from the device to identify a sleep interval; and assigning, with a classifier, sleep stages to epochs of the sleep interval.

Disclosed herein are an apparatus and a method for estimating the behavior of a user based on an image converted from sensing data. The apparatus for estimating the behavior of a user based on an image converted from sensing data includes memory for storing at least one program, and a processor for executing the program, wherein the program performs acquiring sensing data measured by one or more behavior measurement devices worn by the user, converting sensing data of the user obtained for a predetermined time period into images, and estimating the behavior of the user from the images of the user based on a pre-trained model.

The skeletal position of a pitcher at the moment of foot strike in the delivery of a pitch is compared against a plurality of skeletal positions, the plurality of skeletal positions being associated with a plurality of pitchers, each skeletal position being associated with the moment of foot strike in the delivery of a pitch. A value representative of a position of the pitch on a spectrum is provided, the spectrum being defined by a characteristic known about each of the pitchers of the plurality, the characteristic being Tommy John surgery or maximum fastball speed.

A wireless, patient-worn, physiological sensor configured to, among other things, help manage a patient that is at risk of forming one or more pressure ulcers is disclosed. According to an embodiment, the sensor includes a base having a top surface and a bottom surface. The sensor also includes a substrate layer including conductive tracks and connection pads, a top side, and a bottom side, where the bottom side of the substrate layer is disposed above the top side of the base. Mounted on the substrate layer are a processor, a data storage device, a wireless transceiver, an accelerometer, and a battery. In use, the sensor senses a patient's motion and wirelessly transmits information indicative of the sensed motion to, for example, a patient monitor. The patient monitor receives, stores, and processes the transmitted information.

A method for assessing the orthopaedic performance of a joint of a patient can comprise implanting at least a first and second RF wirelessly detectable markers in first and second bones associated with a site and determining and storing their positions before a surgical procedure is performed. The procedure can be carried out on the site and the positions of the first and second markers can be detected and stored after the procedure has been completed. The detected positions can be used to generate a representation of the orthopaedic performance of the joint after the procedure.

An apparatus for determining balance compensation includes a platform, sensors and a processor. The platform is configured for a person to stand on the platform. The sensors are coupled to the platform and measure at least one of a weight and a pressure. The processor determines a balance of the person based on the measurements of the sensors.

Medical diagnostic images that are embedded with contact messages about a professional are sent to a patient for sharing with others. Although the images may be obtained using any of a variety of imaging devices, in some instances, the images may be obtained using a soft-tissue-injury diagnostic system for diagnosing soft tissue injury within a patient. A visual display is configured and arranged for receiving and displaying the medical diagnostic image. Personalized contact messages are then embedded within the image as a watermark to with information about the professional, such as an electronic business card, contact information, or hyperlinks to additional information. The sharable image with embedded messages is electronically sent to the patient for sharing with others. Personalized contact messages may also be embedded in non-medical images for sharing with others.

A system for monitoring a patient's orientation to reduce a risk of the patient developing a pressure ulcer can include one or more hardware processors that can receive and process data from a sensor to determine the patient's orientation. The one or more hardware processors can maintain a plurality of timers associated with available orientations of the patient. The one or more hardware processors can modify a value of the plurality of timers based on an amount of time the patient is oriented in the plurality of orientations. The one or more hardware processors can generate an interactive graphical user interface on the display screen. The user interface can include a graphic for illustrating an orientation history of the patient. The one or more hardware processors can modify an appearance of the graphic based upon the values the plurality of timers.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.
