A Study on Biofeedback ¥±
Hwang Sang-Jong

Abstract
A study was done to investigate the biofeedback of frontalis muscles in normal subjects.
The subjects were divided into feedback, no feedback and flase feedback
Baseline recording on the first session and the deta of muscle tension during 5 sessions of biofeedback trainning were analyzed.
The results were as follows;
1. Mean baseline level of frontalis muscle tension on bofeed back was 1.41+0.37uv.
2. Comparing the results of ANOVA by training condition at each session, a significant difference was found from the 4th session.
3. Comparing the results of t-test of mean muscle tension between types of three training conditions during each of the 5 sessions, biofeedback group had a statistically significant difference in comparison with no feedback group or false feed-back group."
