A method for determining the anatomic condition of components of the body
of a human or of an animal is disclosed comprising producing a sound
signal in a selected component of the body by at least one of passive and
active movements of at least one joint. The method includes recording a
sound signal at a point adjacent to the selected component of the body
and evaluating the sound signal. An auxiliary device selected from the
group consisting of a splint, an orthosis and an exercise machine is used
which ensures a repeatable movement determined by the design of the
auxiliary device. The sound signal caused by the movement is recorded and
evaluated by a spectral analysis of frequencies and amplitudes contained
in the sound signal. A comparison is made with reference patterns of the
spectral analyses for the diagnosis of the anatomic condition. The result
of a diagnosis is indicated as at least one of a print out and a screen
display and wherein the joint investigated is schematically illustrated
on the screen display, optionally with associated soft tissues, tendons
and ligaments. The diagnosis is indicated visually, by at least one of
coloring, lighting up of and flashing of damaged positions.
