Contraindications
1. Therapeutic ultrasound should not be applied over the pregnant
or potentially pregnant uterus. Therefore, therapeutic ultrasound
should not be applied over the uterus unless specific assurance can
be attained from the patient that she is not pregnant.
2. Patients who have cardiac pacemakers should be protected from
direct ultrasound exposure over the thorax to protect the lead
wires and pacer from such exposure.
3. Therapeutic ultrasound should not be applied to the eye.
4. Applications of therapeutic intensities of ultrasound should be
avoided over the heart.
5. Neoplastic tissues or space occupying lesions should not be
exposed to ultrasound.
6. Ultrasound should not be applied to the testes to avoid increases
in temperature.
7. Areas of thrombophlebitis should not be treated with therapeutic
ultrasound due to the increased possibility of clotting or dislodging
a thrombus. Conditions where this might occur are deep vein
thrombosis, emboli and severe atherosclerosis.
8. Tissues previously treated by deep x-ray or other radiation should
not be exposed to therapeutic ultrasound.
9. Ultrasonic treatment over the stellate ganglion, the spinal cord
after laminectomy, subcutaneous major nerves and the cranium
should be avoided.
10. DO NOT treat ischemic tissues in individuals with vascular disease
where the blood supply would be unable to follow the increase in
metabolic demand and tissue necrosis might result.
11. DO NOT apply therapeutic ultrasound over a healing fracture.
12. Ultrasound should not be applied over the epiphyseal areas (bone
growth centers) of the bones of growing children.
13. DO NOT use this device on patients who have a cardiac pacemaker,
implanted defibrillator, or other implanted metallic or electronic
device, because this may cause electric shock, burns, electrical
interference, or death.
14. DO NOT use this device on patients whose pain syndromes are
undiagnosed.
