5 Intended Use Ultrasound therapy and StatUS
5.1 Ultrasound
Ultrasound is a mechanical energy consisting of high-frequency vibrations applied by means of
an ultrasound treatment head. These vibrations pass through the tissue of the body and are
gradually absorbed and transformed into heat. The resulting temperature increase triggers
biological changes to occur in the tissue for the relief of pain, relaxation of muscle spasms and
reduction of joint contractures.
5.1.1 Indications/Contraindications and Adverse Effects for Ultrasound
Indications:
•
Ultrasound is indicated for conditions that benefit from the application of deep heat: relief
of pain, muscle spasms and joint contractures. The objective of therapeutic ultrasound in
the treatment of selected medical conditions associated with the chronic and sub chronic
conditions of bursitis/capsulitis, epicondylitis, ligament sprains, tendinitis, scar tissue
healing and muscle strain is to reduce pain.
Contraindications:
•
The established contraindications to heat therapy itself.
•
In an area of the body where a malignancy is known to be present.
•
Over or near bone growth centers until bone growth is complete.
•
Over the thoracic area if the patient is using a cardiac pacemaker.
•
Over a healing fracture.
•
Over 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.
•
In the presence of metal implants of any type.
•
Patients with sensory loss on the area to be treated.
•
The gonads or to the developing fetus.
•
The heart.
•
The brains.
•
The testicles.
•
The eyes.
•
Ultrasound should not be used on unconscious patients.
Precautions and Warnings:
•
Precaution should be taken when using therapeutic ultrasound on patients with
hemorrhagic diatheses.
•
Ultrasound treatment presents a potential safety hazard in patients whose pain response
has been decreased because of disease, previous surgery, ionizing radiation therapy,
chemotherapy, or general or regional anesthesia. It may cause burns. Do not use on
insensitive areas or in the presence of poor circulation.
•
Large thermal doses may result in regions of thermal aseptic necrosis which may not be
apparent on inspection of the skin.
•
Always ensure proper hygiene (see 12.1 for cleaning). Only apply the ultrasound
treatment head on intact skin. When treating damaged skin (for example ulcers), only
place the treatment head on the edges of the wound, never on the wound itself.
•
See also chapter 3, Precautionary Instructions, for general Warnings and Precautions.
Relevant Hazards:
•
Use of ultrasound in treating areas above the shoulders may pose relevant hazards.
While it is recognized that certain specific conditions involving the eyes can and have
been treated by specialists qualified by training, knowledge and experience to administer
such treatments, such application carries with it recognized hazards of applying heat to
the eyes.
