Ultrasound
Instructions
The following Ultrasound Instructions are for 25 Series 825 and 925 USERS ONLY. The Dynatron 25 Series 525 and 625 do not
offer the Ultrasound feature.
Ultrasound therapy channels sound waves through muscle, nerve, bone, and connective tissue to aid in reducing pain,
muscle spasms, and joint contractures.
The physiological effect of Ultrasound therapy depends upon the frequency of the Ultrasound signal. The lower frequency
(1 MHz) penetrates deeper than a higher frequency (such as 2 MHz or 3 MHz), thus the practitioner can decide which
frequency to use according to the condition and depth to be treated.
A section in this manual entitled “Ultrasound Usage Cautions” provides some general guidelines for Ultrasound treatment
and selection of the appropriate soundhead to help ensure safe and effective treatments are delivered to your patients. Further
information about Ultrasound application may be obtained from published medical literature.
WARNING
• ALWAYS keep the applicator soundhead in constant motion.
• ALWAYS keep the soundhead properly coupled to the patient’s skin or submerged underwater when intensity
is turned on.
• Use ample conductive gel to ensure good coupling throughout the treatment. If needed, apply additional gel
during the treatment.
• See the section of this manual entitled “Contraindications, Warnings, and Precautions” for Ultrasound treatments.
• Be alert for any sign of periosteal (bone) pain.
• Be sure to read all instructions for operation before treating a patient.
• Use of controls or adjustments or performance of procedures other than those specified herein may result in
hazardous exposure to ultrasonic energy.
