4. Use a little lower intensity for the rst treatment to gauge response.
5. Patient feedback is key. A treatment should feel warm, but the patient should never feel heat, pain, stabbing, pricking
or dull ache.
Acute Conditions: ........................................ 0.1 – 0.5 W/cm

(no appreciable thermal eect).
Sub-Acute Conditions: ........................... 0.5 – 1.0 W/cm
2
(Mild to Moderate thermal eect).
Chronic Conditions: ............................1.0 – 2.0 W/cm

(Moderate to Strong thermal eect).
Frequency of Treatment
Treatment can be given daily. It is not uncommon to give Ultrasound twice daily, but this may be excessive. Some guidelines
may be helpful.
1. Daily may be the best maximum frequency.
2. Ultrasound can be eectively given every other day.
3. Ultrasound should give some positive benets by the 3rd or 4th application. If not, discontinue the treatment and
consider other options.
4. A maximum of 12 to 15 Ultrasound treatments should be given. If the result desired has not been reached by this
point, Ultrasound may not be the proper choice. EXCEPTION: Some Chronic conditions which cause adhesions.
Usage Cautions – Combination Treatments
When using a Stim device in conjunction with a 25 Series device to output Stim through the soundhead, observe all contra-
indication, warnings, precautions, and usage cautions provided by the manufacturer for all modalities involved.
Potential for Burns or Periosteal Pain
Some patients’ skin is more sensitive to Ultrasound output. is can cause a reaction similar to a heat rash. It is also possible
for a patient to suer a burn from Ultrasound therapy if the therapy is not administered properly. is can occur for the
following reasons:
• Intensity (power) too high
• Frequency too low
NOTE: It is very common that intensity is always 1.5 W/cm

. is is incorrect in many cases. A more specic
intensity should be used based on patient response and stage of injury.
