Abstract

The purpose of this study was to determine the effect of application methods in ultrasound on skin temperature and muscle blood flow. Thirty healthy volunteers without known vascular problems participated and randomly divided into three groups such as continuous wave group (CWG) which received a ultrasound treatment of continuous-wave, intermittent wave group (IWG) which received a ultrasound treatment of intermittent-wave at a dosage of $1.5\;W/cm^2$ for a duration of 5 minutes, and placebo group (PG) which received a ultrasound treatment of no-wave and no-dosage ultrasound to the anterior forearm. Blood flow and skin temperature was measured using MP 150 before and after ultrasound administration. The results were as follows : 1. Administration of ultrasound in all groups had increased effect on skeletal muscle blood flow immediately after treatment and for up to 10 minutes posttreatment. 2. CWG and IWG showed increased skin temperature immediately after a ultrasound administration and maintained to 10 minutes posttreatment. PG showed increased skin temperature immediately after a ultrasound administration but returned to initial state to 10 minutes posttreatment. 3. The great change on skeletal muscle blood flow among three groups showed in CWG ($6.27{\pm}1.72$) and then displayed in PG ($5.12{\pm}1.66$) and IWG ($4.61{\pm}2.19$) in order. 4. The vast change on skin temperature among three groups showed in CWG and then IWG and PG in order.
