Materials on the issue of joint auscultation

The question of the meaning of listening to the joints cannot be considered resolved. So far, we are in the stage of accumulating facts in this regard. In the literature, auscultation of the joints, as a method of research for the disease of the latter, has so far been given little attention. Not only the question of how valuable this research method is for the clinic is not sufficiently clarified, but also what data in the sense of sound phenomena we have when listening to normal and pathologically altered joints. Therefore, I consider it possible to report on the data that I received during auscultation of the knee joints in 373 people. The technique was as follows: a phonendoscope was placed on the knee joint area, after which the subject slowly performed flexion and extension movements while sitting on a couch (Prof. The doctor advises putting the patient's hands under the leg, this has not been done in my experiments). The movements were made repeatedly. Both joints were ausculted. Most patients have a hearing. it was performed several times (2-4) with different intervals: from a few days to 1½ months.
