Description of the functions of the training

Training time
The training time can be preset from 1 to
60 minutes in every training program. Stand-
ard is 30 minutes.
Automatic change of direction of rotation
THERA-vital changes every 4 minutes in
passive training the direction of rotation.
While training actively, there will be no chang-
ing of the direction of rotation.
Sensitivity of spasm control
This feature enables you to set the borderline
for the sensory of THERA-vital to notice a
wrong reaction of the patient that will cause
the engine to stop, in order to minimize any
possible overstraining.
For patients tending to show any symp-
toms of spasm choose the adjustment as
follows:

Spasm program
The spasm-feature of THERA-vital sets in
which direction the device starts again after a
spasm.
Choose the adjustment as follows:
Forward: when having the tendency for
stretch spasm;
Backward: when having the tendency for
bowing spasm.
Automatic Number of Revolutions-Adjust-
ment
At the active training the adjustment of the
number of revolutions automatically adjusts
to a higher capacity level of the patient, if the

Active muscle-support
This function helps patients that are unable to
get a smooth rotation with just one leg or arm.
The motor supports the active side by periodi-
cally doing the work on the in-active side
needed. The feature works like a flywheel at
mechanical training devices, only that
THERA-vital does not have to get driven. Any
observers will not notice that the patient only
works one-sided. Is the patient able to work with
both sides the active muscle-support is not to
notice.

Please set the motor power as follows:
high when pedal radius is big
(100 % motor power),
medium when pedal radius is medium
(approx. 80 % motor power),
low when pedal radius is small
(approx. 60 % motor power).
Small pedal radius and adjustment of
motor power on "big" can effect very
big powers on the patient.
