can make the detection of the users level of emotional arousal. These results warrant further research to determine how grounding affects the body. Key words: electrodermal activity (EDA), galvanic skin response (GSR), skin conductance. PR and PI variances increased toward the end of the grounding period, and this change persisted after ungrounding. BO variance decreased during grounding, followed by a dramatic increase after ungrounding. RR variance increased immediately after grounding then decreased. RR increased during grounding, and the effect lasted after ungrounding. There was an immediate decrease in SC at grounding and an immediate increase at ungrounding on all subjects. The facility was chosen in a quiet area for its very low electromagnetic noise.įor each session, statistical analyses were performed on four 10-minute segments: before and after grounding (sham grounding for control session) and before and after ungrounding (sham ungrounding). This study was performed in a rented facility in Encinitas, California. The parameters reported here are: skin conductance (SC), blood oxygenation (BO), respiratory rate (RR), pulse rate (PR), and perfusion index (PI). had a BMI in the normal range (18. To accurately measure the electrical response of the human body, the circadian rhythms of the elec. measurable effect on the resistance level of his skin. This report presents results for 5 of the 18 parameters measured. EDA is also known as the galvanic skin response, electrodermal response, skin conductance, etc. Galvanic skin response (GSR) was chosen to measure the effects of evaluation in this study. Sham 2-hour grounding sessions were also recorded with the same subjects as controls. They were seated in a comfortable recliner and measured during 2-hour grounding sessions, leaving time for signals to stabilize before, during, and after grounding (40 minutes for each period). Subjects were screened for health problems using a commonly used health questionnaire. In this exercise, you will measure the muscular twitch response to nerve stimulation and show recruitment in the twitch response as the stimulus strength increases. Exercise 2: Twitch Response and Recruitment. This study was set up to reproduce and expand earlier electrophysiologic and physiologic parameters measured immediately after grounding with improved methodology and state-of-the-art equipment.Ī multiparameter double-blind experiment was conducted with 14 men and 14 women (age range: 18-80) in relatively good health. Wipe the paste off your skin and reapply a small amount to the metal buttons of the stimulating electrode. Previous studies have shown that grounding produces quantifiable physiologic changes. Galvanic Skin Response This measures the electrodermal activity which reflects sweat gland activity that are.
