The Effect of Electrical Stimulation Level on Autonomic Nerve System in Normal Adults

The purpose of this study was to investigate the effect the interferential current (IFC) stimulation level according to autonomic nerve system (ANS) of healthy adults. IFC measured with adhesive 2-pole electrodes padon T1 ∼ T4 spinal cord segment level that electrode stimulation of 20 min after. A total of 45 healthy adults participated in the study, who were randomly divided into three groups: 15 of sensory level stimulus group (100 bps,10 ∼ 12 ㎃ ), 15 of exercise level stimulus group (5 bps, 45 ∼ 50 ㎃ ), 15 of noxious level stimulus group (100 bps, 80 ∼ 90 ㎃ ). Measured items were sympathetic activity and parasympathetic activity. In order to identify the changes in measurement variables before electrode stimulation and after and 30 min stimulation. The comparison of sympathetic and parasympathetic activity in each group revealed that they was changes of after vs 30 min in afterelectrical stimulation time(p<.05).
