Assessing Joint Condition Using Acoustic Sensors
A new non-invasive tool for cartilage assessment, exercise and sports management, and prevention of osteoarthritis is provided. In various embodiments, cartilage condition is assessed using audible signals from joints. Assessment test results are used to provide feedback regarding joint stress and friction that is related to physiological or pathological loads. Data obtained from audible signals are processed to provide an index that can be interpreted by a user or third parties. The index is useful as a baseline for exercise practices, training routines, wellness programs, or rehabilitation protocols.

- 1. A system comprising:
a contact microphone; a position sensor; a processor operatively connected to the contact microphone and the position sensor; a computer readable storage medium having program instructions embodied therewith, the program instructions executable by the processor to cause the processor to perform a method comprising:
receiving from the contact microphone audio comprising sounds emanating from a human joint during flexion;
receiving, from the position sensor, motion data of the human joint;
synchronizing the motion data with the audio;
extracting a plurality of features from the audio;
providing the plurality of features and the motion data to a trained classifier;
obtaining from the trained classifier a first score indicative of joint health; and
displaying the first score with an indication to perform follow-up when the score is below a predetermined threshold.
- 16. A method comprising:
receiving audio from a contact microphone, the audio comprising sounds emanating from a human joint during flexion; receiving, from a position sensor, motion data of the human joint; synchronizing the motion data with the audio; extracting a plurality of features from the audio; providing the plurality of features and the motion data to a trained classifier; obtaining from the trained classifier a first score indicative of joint health; and displaying the score with an indication to perform follow-up when the score is below a predetermined threshold.
