The evolution of the means of the systolic and diastolic blood
pressure measurements and of the heart rate measurements in the
study group over the duration of the individual treatment sessions
is shown inFig. 1. The mean of post-session systolic blood pressure
measurements was higher, except in a few sessions, than the mean
of pre-session measurements. However, a trend can be observed
towards a levelling-off and towards a decrease below the mean of
the pre-session measurements from session 20 onwards
