ULTRASOUND MODALITY INFORMATION
DYNATRON® 25 SERIES™ | OPERATOR’S MANUAL 57
• Holding the soundhead in one place on the patient’s skin
• Moving the soundhead too slowly
• Treating an area where sensory nerve damage is present with a loss of normal skin sensation
• Time (Caution: Don’t treat too long).
Bony prominences are especially susceptible, as they reect sound waves and increase intensity to the periosteum resulting
in a burning sensation. Desensitized areas can be overheated or burned without the patient realizing it, so extreme care must
be taken with these patients (e.g. diabetes, neural damage, etc.)
Burns can be avoided as long as the treatment causes no pain, tingling, excess heat or aching (for patients with normal skin
sensation). Use sucient coupling agent and make sure there are no bubbles in the gel. When treating in water, clear the
bubbles o the soundhead and o the patient’s skin.
An un-calibrated soundhead can also cause tingling, excess heat, aching, or a burning sensation.
