The purpose of this study was to assess the efficacy of several thermal therapies using ice pack, moist-hot pack and ultrasound, separately and concomitantly and to obtain the background information on the vascular changes after thenmophysical therapies.
The author had used. 15 healthy subjects were examined and the subjects were divided into 5 groups; ice pack,
moist-hot pack, ultrasound, ice pack and moist-hot pack, ice pack and ultrasound.
Observation were made immediate before and 0, 5, 10, -20, 30, 45, 60, 90. minutes after treatment. . Thermography was performed in an Agema 870 thermovision with 0.11C difference of gradual temperature shift.
The results ´ were as follows ;
1. Using ice pack only, the surface temperature of the masseter region was increased lapse of time, and most remarkably 90 minutes after the treatment.
2. Using moist-hot pack only, the surface temperature of the region was remarkably increased immediately after the treatment, but decreased lapse of*time.
3. Using moist-hot pack with ice pack, the surface temperature of the face was remarkably increased immediately after the treatment, and decreased lapse of time. Hyperthermia was maintained for a longer time as compared with the group of moist-hot pack only.
4. Using ultrasound only, the surface temperature of the region was increased gradually, and most remarkably 30 minutes after the treatment, but decreased in the course of time.
5. Using ultrasound combined with ice pack, the surface temperature of the region was gradually decreased until 30 minutes after the treatment, and decrease to some extend at 45 minute. And then a gradual increase observed over the remaining period of the experiment.
6. Hyperthermia were maintained for a longer time in the groups using ice pack combined with moist-hot pack and ultrasound as compared with the other groups.
Our data suggest that ice pack can promote the efficacy of other thermal therapies.
