Comparison between CV4 and EV4 - Osteopathic Research

37
4.3 Method
For this research, 12 subjects were used (N = 12, n = 7m, n = 4f) aged 21 to 43.
The measurement occurred between 18.4.2001 and 22.6.2001.
Each was subjected to a CV4, EV4 and placebo technique at one week interval.
The measurements were done via the Biofeedback-system before and during the
techniques, to record the course.
The following parameters were captured:
‣ skin-conductivity
‣ skin-temperature
‣ pulse-rate
‣ breathing-rate
‣ breath-amplitude
The measurement on a subject occured on the same week day, at the same time
(+/- ½ hour) in order to limit variations due to the time of day.
In order to minimize subject influence on the measurements, the techniques
were made anonymous by initializing each technique. Test subjects were not
informed of this process so that they did not know which technique was being
performed.
The techniques’ sequence order was determined prior to the beginning of the
study. Each test subject picked a closed envelope in which his/her sequence was
enclosed.
