Ultrasound treatments typically require clinicians to perform the treatment by moving the ultrasound transducer throughout treatment area. However, the AutoSound performs the “movement” by activating and deactivating 4 transducer heads on a hands-free unit. The study purpose was to determine whether heating differences exist between traditional ultrasound and AutoSound treatments. Twelve healthy volunteers were treated with both the AutoSound and the Omnisound (3-MHz frequency; 1 W/cm2; 8 minutes). The tissue returned to baseline prior to the second ultrasound treatment. Two thermocouples measured triceps surae temperature 1-cm deep. A 2×2×2 ANOVA determined differences between site, time, and modality. Both ultrasound treatments caused an increase in intramuscular temperature (P < .01): Omnisound from 34.1±1.1°C to 37.3±1.6°C and AutoSound from 33.9±1.0°C to 35.9±1.4°C (P < .01). Clinically, a treatment with the AutoSound may have to last longer than one with an Omnisound ultrasound unit to achieve comparable heating using similar parameters.
