Abstract
Context: The research surrounding the thermal effects of ultrasound measures temperature solely in the middle of the effective radiating area (ERA). Objective: To determine whether uniform intramuscular heating is achieved throughout the ERA at both 1 and 3 MHz. Participants: Seven male and three female students with no history of lower leg trauma within the past six months. Inventions: Each subject underwent two ultrasound treatments conducted in the triceps surae muscle group. Ten minute baseline temperatures were records every 30 seconds followed by a ten minute baseline ultrasound treatment. A two-way (site X time) repeated measures ANOV A was used to determine statistical significance. In the case of a significant interaction, post-hoc testing was performed using a simple effects analysis with the Bonferroni adjustment. Results: A significant site-by-time interaction was observed for both the 1 and 3 MHz treatments. Conclusions: The temperature for both 1 and 3 MHz differ significantly suggesting that uniform heating does not occur.
