ment was best predicted by the standard
protocol (.48 and .73 for occurrence and
amplitude, respectively).
The changes between first and second
recording were evident for the tremor occurrence
but significant only with multivariate
tests and more so during the 24-hmonitoring
than during the laboratory phases.
In the case of the 14 patients with
considerable tremor activity during the rest
and postural tremor test in the initial recording,
the decrease in the tremor occurrence
and the amplitude was more significant.
This decrease in tremor can be interpreted
as a global indication of treatment
effects.
Some patient outcomes were descibed in
detailed casuistics. Of particular interest is
that different courses (with respect to the
rest and postural tremor tests and monitoring
outcome, as well as to the divergency
of tremor occurrence and amplitude) were
evident. In some cases, an increase of
tremor between the first and the second
recording was demonstrated.
There was only a small relation between
tremor variables and body and hand position,
whereas the pooled within patients correlation
between heart rate and tremor occurrence
was remarkable (r=0.25), that is,
because only monitoring segments without
movement were used, high tremor activity
is related to mental/emotional strain. Psychophysiological
episodes in a restricted
sense were seldom accompanied by high
tremor activity resulting from emotional
stress; the methodology of recording does
not yet allow a sufficient differentiation of
such — normally rather seldom — events.
The accelerometrical methodology for the
measurement of tremor activity under laboratory
and real-life conditions (monitoring)
can be considered as to be sufficiently developed.
Possible practical applications are
discussed.
