5.3 Precautions
1. Ultrasound should not be applied in areas of reduced sensation or circulation or over anesthetic areas.
Patients having reduced sensation will not be able to notify the practitioner of discomfort if ultrasound
intensities are too high. Patients with compromised circulation may have an excessive heat buildup in
the treatment area.
2. Operators should not routinely expose themselves to therapeutic ultrasound. The applicator handles for
the Sonicator 740 have been designed to allow the practitioner to perform underwater treatments
without exposing the hands to ultrasound.
3. If a patient complains of periosteal pain (deep, achy pain) during ultrasonic treatment, intensity should
be reduced to a comfortable level.
4. Any bleeding tendency is increased by heating because of the increase in blood flow and vascularity of
the heated tissues. Care, therefore, should be used in treating patients with therapeutic ultrasound who
have hemorrhagic diatheses or bleeding disorders.
5. Moving technique of the applicator should be used when applying therapeutic ultrasound at intensities
greater than 0.5 W/cm² to assure even exposure of tissues to ultrasound.
6. Heating of the joint capsule in acute or subacute arthritis should be avoided.
7. Electric treatment tables or whirlpools which may come in contact with the patient during a treatment
with the Sonicator 740 should be adequately grounded and safety tested to insure safe operation with
the Sonicator 740.
8. The use of therapeutic levels of ultrasound may delay or prevent callous formation in a healing fracture.
