Modifying Treatment Parameters
Treatment parameters can be modified prior to or during a treatment session. To modify a parameter, select
that parameter on the control panel. Treatment time and output intensity are changed using their designated
up or down arrow buttons. Frequency, duty cycle and output display toggle from choice to choice with
repeated touches of their respective buttons. You have the choice to make changes on-line while a session is
in progress, or you may pause the session by pressing the Pause button and make desired changes. If Pause is
your choice, press Start to resume the session after changes are made.
Changing Power-Up Preset Parameters
First, change the parameters to your desired settings. Next, simultaneously touch and hold the Intensity key
and the Display key.
Head Warm
Select this option prior to starting a treatment session and the sound head will warm using a percentatge of
the unit’s power. The Head Warm LED will activate and a fan will turn on indicating heat warming is on.
NOTE: Head Warm is only possible prior to pressing the Start button, thereby initiating a treatment. When the
start button is pressed, Head Warm is turned off.
Basic Guidelines for Ultrasound Utilization
•
Patient Position
• Position the patient in a correct anatomical posture to allow for effective treatment.
• For example, when attempting to treat the bicipital groove of the humerus, be sure to
position the arm in an externally rotated position to expose the target tissue to the
ultrasound waves.
•
Importance of Transducer to Skin Contact
• Ultrasound energy will not pass into the target tissue if the angle of the transducer head
to the surface of the skin is greater than or equal to 15 degrees (Summer and Patrick, 1964).
• If air is trapped in the coupling agent or between the skin and the transducer, attenuation of the
ultrasound energy will occur resulting in diminshed results.
• The transducer head may be damaged if there is poor contact during treatment because the crystal
develops standing waves when the ultrasound vibration is not unloaded (Griffin, 1992).
