A method for acquiring image data of a body part of a patient by means of a ultrasonography device comprising the following steps: providing a transducer of the ultrasonography device, said transducer comprising a first orientation sensor; attaching a second orientation sensor to the skin of the patient above the body part; detecting the orientation of the first orientation sensor relative to the second orientation sensor and verifying, whether the relative orientation corresponds to a target value; and acquiring image data of the body part, once the relative orientation corresponds to the target value.

A monitoring and/or therapy apparatus can include a contact layer having a stretchable or substantially stretchable substrate, at least one strain sensor coupled with the contact layer, and electronic circuitry electronically coupled with the at least one strain sensor configured to determine an amount of an elongation of the at least one strain sensor based on a change in a resistance or capacitance of the at least one strain sensor. The at least one strain sensor can include a plurality of stretchable tracks positioned on the substrate, and can be configured such that the resistance of the at least one strain sensor increases as the contact layer is elongated and/ or curved. In some arrangements, the apparatus and/or the substrate can be attached to or adjacent to a user’s joint, and/or a wound, and can be configured to have reduced pressure applied to the space under the contact layer..

Disclosed is a method for determining an unworn state of a sensor system comprising a pair of sensors configured for mounting on first and second body parts either side of a joint. The method comprises: obtaining one or more measurements from each sensor; calculating a relative angle between the two sensors using one or more of the obtained one or more measurements; calculating, using one or more of the obtained one or more measurements, a joint angle between the first and second body parts, where the joint angle is defined in a plane of normal bending of the joint; and determining, based on the calculated angles, whether either of the sensors is not mounted and if so, determining that the system is in an unworn state. Also disclosed is a system for providing information about a joint.

A method of calibrating a pair of body mounted sensors, the method comprising the steps of: (a) in a baseline position of a joint to be measured, determining a first offset between a measured joint angle and an angle between pair of sensors, one mounted on each side of the joint to be measured, so as to calibrate the sensors; (b) after at least one of the sensors has been removed and reapplied, placing the joint back into the baseline position such that the sensors are in a second configuration relative to each other; and (c) determining a second offset between the measured knee angle and an angle between the pair of sensors in the second configuration in order to recalibrate the sensors such that, in each of the first and second configurations, the same joint angle for the baseline position is reported.

A method for optimizing at least one exercise for a first user. The method includes receiving first user data including attribute data associated with the first user and outcome data associated with the exercise. The method includes generating, based on the first user data, initial target data. The initial target data is associated with at least one of the first user, the exercise apparatus, and the exercise. The method includes receiving measurement data associated with at least one of the first user, the exercise apparatus, and the exercise. The measurement data is associated with one or more sensors. The method includes determining differential data based on one or more differences between the initial target data and the measurement data. The method includes generating, via an artificial intelligence engine and based on the differential data, a machine learning model trained to generate optimized target data.
