Abstract

To study the effectiveness of ultrasound therapy, 13 healthy people were asked to perform elbow flexion exercise of biceps brachii and their reaction times (RT), premotor times (PMT) and motor times (MT) were measured 12 times before and after intervention in the ultrasound irradiation group and non-irradiation group. The irradiation group was exposed to 1 MHz ultrasound at 1 W/cm2 for five minutes on biceps brachii muscle by the stroke method. The stroke method was performed on the non-irradiation group at 0 W/cm2. Both groups showed no difference in the twelve mean values before and after the intervention, but RT showed significant differences in the mean values up to 7 times, and MT up to 6 times, just after the irradiation, from the mean values before the intervention. The PMT mean value up to four times showed a significant difference from the mean value before intervention. These reaction times, suggest that the alteration of muscle tension and arousal decline just after irradiation, but recover soon with increasing number of measurement.<br>
