    Therapy 4.3 Safety Precautions for Stimulation Current Intensity Please observe the following safety precautions when adjusting the intensity of the stimulation current applied to the patient: • Always bear in mind that the patient may display an altered sensitivity, and may therefore not be properly aware of the current strength.

  • Page 27: Modes Of Attaching The Electrodes

    Therapy (5) Select the size of the electrodes according to the area of treatment following Area of electrodes as small as necessary but as large as possible the principle: A larger electrode area usually makes treatment for the patients more pleasant. (6) Plug the plate electrodes into the well-moistened electrode covers and attach them to the patient.

  • Page 28: Iontophoresis

    Therapy Monophase current modes resemble direct current, i.e. every electrode has a defined polarity: + = anode (low-stimulation electrode) - = cathode (high-stimulation electrode). Biphase current modes, however, have a continually alternating polarity, called polarity . The stimulation intensity of both electrodes is identical. Many current modes are preferably applied in biphase mode, as you can reduce the danger of burns even at high doses.

    Therapy Caution Take care that the electrodes are by no means touched after the current is turned up! (8) After treatment, an acoustic signal will be issued. Turn the intensity down to 0. (9) Remove the electrodes and rinse the viscose covers thoroughly. Note The diffused quantity of the agent directly depends on the size of the electrodes, the therapy time and the current intensity.

    Diagnosis: Accommodation Quotient 5 Diagnosis: Accommodation Quotient accommodation quotient Rheobase galvano-tetanus- is the quotient of threshold, i.e. of the intensities with square pulses (1000 or 500 ms) and triangle pulses (1000 or 500 ms) necessary to trigger a minimal contraction. It informs about the accommodation ability of the examined nerve-muscle unit and thus about its degree of damage.
