Abstract

[Purpose] The objective of this research is to verify how changes of irradiation area of the ultrasound therapy(US) affect of normal adult. [Participants] Experiment is conducted on 16 normal adult males. [Method] ROM, tissue temperature and tissue stiffness before and after US treatments on triceps surae muscle with different conditions are compared. The conditions are (1) Treatment area 10 times, duty cycle 100% (2) Treatment area 2 times, duty cycle 100% and (3) Treatment area 2 times, duty cycle 20%. [Results] ROM and tissue stiffness did not have the significant defference in all conditions. A significant increase in tissue temperature is found in condition (2), when compared with all other conditions. [Conclusions] the possibility that the extensive US intervention was useful was suggested, because ROM and tissue stiffness did not have the difference by the treatment area.
