The criterions of selection of
STIMULATION time and PAUSE
time are fairly simple, also if
necessarily empirical: the higher is
the stimulation level, the smaller
will be the ACTIVATION phase with
respect the REST time. For
example: if I want to stimulate a
muscle to get a maximal
contraction, I have to limit the
contraction time to very few
seconds and have to introduce,
between each contraction. A REST
period equivalent to at least 5
times the contraction period.
To simulate the voluntary
contraction, or simply to make less
annoying the stimulation, it could
be beneficial to introduce a
PROGRESSION phase and a
REGRESSION phase; we’ll call the
two new phases respectively RISE
time and FALL time
