This chapter provides you with notes on positioning the electrodes and general
information on starting a short wave therapy.
5.1
Positioning the electrodes
Electrodes have to be positioned on the part of the body to be treated according to
the medical indication (refer to
The electrodes must be positioned so as to avoid overheating due to edge effects.
The surfaces of the electrodes must be nearly parallel to the area being treated. It is
