Researchers have recommended certain ultrasound treatment parameters for deep heating; however, we observed different parameters in the clinical setting.
To compare the treatment effect of using observed clinical parameters (OCP) from 8 clinicians to the treatment effect of using the recommended parameters (RP) sited in research.
2 × 2 repeated measures design.
Sports injury research laboratory.
Ten healthy volunteers.
Two 1 MHz treatment, 1 RP treatment (1.5 W/cm2, 10-min, area-2 to 3 × ERA), and 1 OCP treatment (1.3 W/cm2, 8-min, area 3.9 × ERA)
Main Outcome Measure:
Tricep surae temperature 3 cm below superficial tissue
The RP treatment increase temperature from 36.4 ± 1.0 to 40.3± 2.0°C, which was a greater change than the OCP (36.5 ± 1.2 to 38.2 ± 1.6°C).
The OCP treatment resulted in a lower heating affect than the RP. Small change in treatment area, intensity, and duration can have a large effect on temperature change.
