Systems and methods for monitoring physical therapy of the knee and other joints

A system for monitoring a joint of a subject is described. The system includes at least one sensor configured to be coupled near the joint of the subject, the at least one sensor configured to sense one or more measurements of the joint. The system also includes a computing device comprising a digital processing device configured to receive the one or more measurements, determine one or more joint parameters based on the one or more measurements, generate a user interface for display, the user interface including a graphical representation of the one or more joint parameters. The digital processing device is also configured to compare the one or more joint parameters to a predetermined threshold and generate an icon for display within the user interface. The icon being generated in response to one of the one or more joint parameters exceeding the predetermined threshold.

Claims preview

1 . A system for monitoring for the presence of an infection or inflammation in a subject, the system comprising: at least one adherent sensor configured to be coupled to skin adjacent to a joint of the subject, the at least one adherent sensor configured to sense one or more mechanical measurements about the joint and a temperature of the skin about the joint, wherein one or more mechanical measurements comprises measurements of a stretching or contraction of the at least one adherent sensor, the at least one adherent sensor including a transmitter configured to transmit the sensed mechanical measurements and temperature to a local computing device; and a remote computing device in communication with the local computing device, the remote computing device comprising a processing device configured to: receive data from the local computing device concerning the sensed mechanical measurements and temperature, determine the presence of infection or inflammation by comparing the received data against a baseline for the subject which includes an identity of a coincidence of stretching of the at least one adherent sensor with an increase in sensed temperature; and transmit an alert to the local computing device if the determination indicates the presence of infection or inflammation, wherein the system is configured to identify one or more cycles of flexion or extension on the joint, determine one or more impacts on the joint, and determine a gait pattern of the subject based on the identified one or more cycles of flexion and extension and the one or more impacts on the joint; and wherein the gait pattern is indicated by a coincidence of the one or more cycles of flexion and extension with the one or more impacts on the joint. 2 . The system of claim 1 , wherein the least one adherent sensor comprises a replaceable enclosure and a sensor assembly removable from the enclosure, the replaceable enclosure comprising the adherent surface and the sensor assembly comprising a mechanical sensing element and the transmitter. 3 . The system of claim 1 , wherein the mechanical measurements comprise stretching or shrinkage of the at least one adherent sensor, an oxygenation of tissue adjacent the joint, a humidity of the tissue adjacent the joint, muscle activity of the joint, an electrical impedance of the tissue adjacent the joint, an acoustic impedance of the tissue adjacent the joint, or one or more biomarkers.
