ULTRASOUND APPLICATION TECHNIQUES
The following guidelines should be followed when applying ultrasound for therapeutic treatment.
Note:
Make sure that the output is switched OFF when the transducer is not in use. Temperature will rise rapidly if the
output is switched ON and the transducer is not in contact with the skin.
1. Prior to starting treatment, cleanse and inspect the US Transducer applicator head for cracks, which may allow
the ingress of conductive fluid; Inspect the treatment head cables and associated connectors; The user should
handle the US transducer applicator head with care at all times, since rough handling may adversely affect its
characteristics
2. Thorough cleansing of the treated area for removal of oils, creams, dirt, and sweat will ensure more uniform delivery
of ultrasonic energy across the skin. After cleansing, an inspection and evaluation of the skin's integrity and
sensation should be done prior to treatment.
3. Test the patient’s skin in the desired treatment area for sensory response prior to the application of ultrasound
therapy. If areas of anesthesia or lack of temperature sensitivity are found, use caution and low doses (sub-
thermal). Care should be exercised with these patients, as they may not detect damaging thermal effects.
4. Use the minimum effective dosage (including power and exposure time). If more therapy is required, a longer
time at a lower output is recommended. Avoid using maximum power levels. For example, a typical comfortable
output should be 0.5 - 1.5 W/cm
2
.
5. Use a slow (approximately 1cm per second) linear or circular motion with the transducer. The treatment area
should be restricted to two of the transducer sizes, which approximates 2 effective radiating areas (ERA). This is
absolutely mandatory if the correct relationships in the calculation equations are to be met.
6.. Apply coupling medium plentifully to the area to be treated. As the superficial skin temperature increases, more
gel may be added to cool the skin while performing the treatment.
7.. ACP applicators are fully waterproof and may be used with underwater technique for the smaller joints where
effective coupling is not possible. The water temperature should be slightly warmer than the target tissue
temperature. It is recommended that the handle is held by the operator without direct contact to the water, to avoid
exposure. If this is not possible, it is recommended that the operator wear gloves to avoid direct contract with
treatment area.
