Nowadays one of the main diseases is the one of movement organs especially that connected
with legs and knee joints, like arthritis or pseudo-arthritis. According to American statistics
about 15% of Americans suffer from orthopedic diseases and more than 7 million need to be
hospitalized because of orthopedic dysfunctions [1].
There are many conventional methods of treatment in such cases, but for 20-25 years the
method of magnetotherapy is being developed [2,3]. There is some fundamental research on
the method and its effects in human organisms but the parameters of physical treatment are
still selected by intuition rather than from the bank of proved data. In the paper we show the
analysis of the resultant agent which is the effect of the stimulation, namely the eddy current
distribution inside the knee joint. The value of current density can help in planning the
treatment.
Mathematical Model and Results
It is obvious that it is the case with magnetic component of EMF
dominated, so the excitation is taken as magnetic component which
is uniform and directed towards the stimulator (leg) (Fig.2). The
value of exciting field is not important as long as the case is
considered linear.

stimulation used for
orthopeadic applications are
