10 General instructions
Ultrasound therapy
During treatment, the patient may not feel unpleasant sensations amounting to pain. A mild
sensation of excitation is permissible.
If, as result of treatment, headache, vertigo, fatigue and/or other (autonomic nervous)
reactions develop, subsequent treatment should be given at a lower intensity.
With continuous and pulsed ultrasound at high intensity a sensation of heat may be felt.
Only a mild sensation of warmth is acceptable.
Before treatment
Please make sure you have read and understood the content of this manual before you start
treatment.
Check the patient for any possible contra-indications.
Test the thermal sensitivity of the treatment area.
The skin of the area in question is cleaned (removal of grease) with soap or 70 % alcohol to permit
optimal transmission of the ultrasound.
Starting treatment
Position the treatment head (do not forget to apply gel on the patient).
When adequate contact is made, the timer will start.
When the contact between the treatment head and the patient is not adequate, LED ring (contact
control indicator) in the treatment head will turn on.
During treatment
The treatment head is kept in slow continuous motion, also for the semi-static method.
During treatment, the displayed ultrasound amplitude can vary around the set value, caused by
fluctuations in acoustical coupling. The patient is regularly asked to report any sensations felt. If
necessary, the treatment is modified;
The intensity can be reduced or a switch is made from continuous to pulsed ultrasound.
If there are indications of poor transfer of the ultrasound energy the contact medium can be reviewed
if necessary, add more contact gel or spread it with the ultrasound treatment head.
Important!
In order to ensure efficient transfer of energy, a contact medium is required between the treatment
head and the body. Air reflects virtually all of the ultrasound energy. The best medium for the transfer
of ultrasound energy is a gel.
• For preference, use Enraf-Nonius Contact-Gel®, as this allows the excellent characteristics of the
treatment heads to be used to their full advantage.
• The gel should be applied to the part of the body to be treated and then spread out with the
treatment head.
Ending treatment
Treatment can be stopped by taking off the treatment head from the patient and setting the timer to
zero. Treatment stops automatically when the treatment time has elapsed.
After treatment
The patient’s skin and the ultrasound treatment head are cleaned with a towel or tissue.
The ultrasound treatment head must be cleaned as described in chapter 14.
The expected effects are checked (e.g. pain, circulation, and mobility).
The patient is asked to comment subsequently on any reactions that may occur.
