Subjecting a prosthesis to ultra sound {RICK MAR IV U.S. FREQUENCY 1 M  HZ—field distribution plane calibrated acoustic power output 0-20 WAVE FORM I C W OR C W crystal size  10 square centimeter area} and utilizing 10 watts of power for 7 minutes

Result:

Within the 7 minute application it appeared a discoloration had found at the site. Under a 4x microscope this discoloration was found to be approximately 500 minute air bubbles.  There was also a temperature rise of from room temperature of 76 degrees to 94 degrees on the surface of the prosthesis.

In subsequent applications of U.S. the exact results were obtained.  The bubbles dissipated in each prosthesis after approximately 6 to 20 hours with no visible residual. {U.S. being ultra sound)

In subjecting the prosthesis to diathermy {Mettler-Shortwave diathermy 27.32 MHZ output} a magnifying glass effect was noted.

The surface of the prosthesis was not sufficient to bring the diathermy up to power. I held the prosthesis in my hand with only 3 to 5 units {calibrated from 0 to 100} of power, almost an instant burning of my hand occurred.  There was no actual burning to my hand as reflexes caused me to drop the prosthesis immediately.

Conclusions:

Ultra sound and diathermy are definitely not recommended by these experiments.

In practical application of D.M.S.O and aspirin on one patient’s reddening of the tissue at the site of application was noted with no reduction of pain.

Not conclusive as far as experimentation was concerned.
