Definitions

  • the present invention is directed to the area of methods, systems, and devices, including user interfaces, for monitoring physical therapy or rehabilitation.
  • the present invention is also directed to systems and methods with user interfaces for monitoring physical therapy or rehabilitation after surgery or implantation of an orthopedic device.
  • Joint replacement surgery is a common orthopedic procedure for joints such as the shoulder, hip, knee, ankle, and wrist. In situations where the patient has wom-out or damaged a joint, it is possible to replace the joint with an implant that can merge with the skeletal structure and restore pain free movement and function.
  • a surgeon Prior to implanting prosthetic components in a joint of a patient, a surgeon generally resects at least a portion of the patient's native bone in order to create a platform, recess, or cavity for receiving at least a portion of the prosthetic components being implanted. During the process of implanting the prosthetic components muscles and tendons must be repositioned and reattached.
  • the patient must go through physical therapy in order to recover from this major surgery.
  • the patient must exercise regularly as well as push for flexibility and balance in muscles that have been displaced. While the goal is to have the patient extend their range of motion, there can be an increased risk of falls or over-extension that can damage the implant and injure the patient. If the patient does not push their rehabilitation and achieve the needed range of motion, they will find themselves with a stiff joint which may require an additional surgical operation (MUA - Manipulation Under Anesthesia) to achieve an adequate range of motion to maintain their active lifestyle. Measuring or monitoring the progress of the physical therapy can be problematic but is very useful for maintaining the patient's dedication and participation.
  • One embodiment is a system for monitoring a patient.
  • the system includes a patient device configured and arranged for communication with a sensor unit disposed on or within the patient, the patient device including a display, a camera, a memory, and a processor coupled to the display, camera, and memory, wherein the processor is configured and arranged for performing actions including: directing, on the display, a user to take a photograph or video of a site on the patient; upon receiving a user-input to take the photograph or video, taking the photograph or video; and storing the photograph or video in memory.
  • the actions further include performing a pigment analysis using the photograph or video to assess health of the site on the patient.
  • the actions further include, when the pigment analysis indicates possible infection of the site on the patient, producing a visual or audible warning to the patient. In at least some embodiments, the actions further include, when the pigment analysis indicates possible infection of the site on the patient, sending a message to a clinician device with an indication of the possible infection.
  • the actions further include sending the photograph or video to a clinician device for assessment of health of the site on the patient.
  • the photograph or video is a video and the actions further include assessing performance of an exercise using the video.
  • the actions further include overlaying one or more lines or angles on the photograph or video to represent position or movement of a limb of the patient within the photograph or video.
  • Another embodiment is a system for monitoring a patient.
  • the system includes a patient device configured and arranged for communication with a sensor unit disposed on or within the patient, the patient device including a display, a memory, and a processor coupled to the display, and memory, wherein the processor is configured and arranged for performing actions including: directing, on the display, a user to input a pain score; and sending the pain score to a clinician device.
  • the actions further include receiving a selection by the user of an exercise; displaying, on the display, a graphical representation of the exercise and a user control which, when actuated by the user, indicates that the user is performing the exercise; and, upon actuation of the user control, monitoring sensor data from the sensor unit to monitor performance of the exercise.
  • the actions further include, during performance of the exercise, display a count of repetitions of the exercise being performed.
  • the actions further include, during performance of the exercise, display either a current value or a maximum achieved value of a range of motion measurement associated with the exercise, as determined from the sensor data.
  • the actions further include receiving from the user a request for an exercise summary; and displaying, on the display, a summary of a plurality of exercises indicating a number of repetitions performed for each exercise over a period of time.
  • the actions further include receiving from the user a request for a progress report for a range of motion measurement; and displaying, on the display, a graph of a plurality of values for the range of motion measurement obtained over a period of time.
  • the actions further include displaying, on the display, a representation of a pathway to a goal for the range of motion measurement with an indication of current progress of the patient toward that goal.
  • a further embodiment is a system for monitoring physical therapy of a patient.
  • the system includes a patient device configured and arranged for communication with a sensor unit disposed on or within the patient, the patient device including a display, a memory, and a processor coupled to the display, and memory, wherein the processor is configured and arranged for performing actions including: directing, on the display, a user to input one or more friends; sending a connection message to each of the one or more friends; and receiving from at least one of the one or more friends a message encouraging the patient to continue the physical therapy.
  • the actions further include, in response to user input, sending a message to at least one of the one or more friends. In at least some embodiments, the actions further include, in response to user input, sending a challenge to at least one of the one or more friends. In at least some embodiments, the actions further include sending a progress report to at least one of the one or more friends, wherein the progress report includes an indication of progress by the patient toward at least one physical therapy goal.

Abstract

L'invention concerne un système de suivi d'une articulation d'un patient, qui comprend de multiples capteurs à disposer à proximité d'une articulation et qui sert à mesurer ou observer des actions ou des quantités physiques associées à l'articulation ; et au moins un module de communication couplé aux capteurs pour recevoir des données provenant des capteurs et transmettre des informations de capteur à un dispositif externe. Le système comprend également un dispositif patient et un dispositif médecin qui peuvent être utilisés pour, par exemple, surveiller et afficher des informations en provenance des capteurs, déterminer une plage de mesures de mouvement à partir des données de capteur, présenter les progrès d'une physiothérapie, prendre une photo ou une vidéo du site sur le patient, obtenir un score de douleur et intégrer des amis pour fournir des encouragements pendant une physiothérapie.
