Description of exerciser functions on submenu

The first menu level comprises the following
items:
❑
Neuro
❑
Ortho
❑
Cardio
❑
Isokinetics
❑
Technical
Neuro (basic setting):
Exercising programmes for patients with neu-
rological conditions, e.g. hemiplegia, paraple-
gia, MS, Parkinson's disease... The method
of exercising is set as Set resistance. The re-
sistance level set remains constant whatever
the pedalling speed. Higher pedalling speeds
mean greater power output.
Ortho:
Exercising programmes for orthopaedic pa-
tients, e.g. following a knee or hip operation.
In this exercising mode, the method of exer-
cising is preset to Set power. The patient is
given a set power level at which to exercise.
The THERA-vital modulates the resistance
automatically according to the pedalling
speed so that the amount of power required is
always the same.
Cardio:
Exercising programmes for cardio-vascular
patients whose heart rate must be kept below
a certain limit. In Cardio exercising mode, a
heart rate limit is set. The THERA-vital re-
duces the resistance as soon as the patient's
heart rate reaches that limit.
Isokinetics:
This exercising program is suitable for pa-
tients with co-ordination difficulties. A re-
quired speed of rotation is set that is then
held constant by the THERA-vital throughout
the entire exercising session. The patient can
thus make a physical effort by actively push-
ing on the pedals without having to co-ordi-
nate the effort with the speed of rotation.
As soon as the pedalling rate drops below the
required speed, the resistance is reduced. If
the pedalling rate exceeds the set speed, the
resistance is increased.
Technical:
The menu option Technical allows you to
make basic settings for options such as mi-
crophone sensitivity, language etc. Entry of a
security code also allows access to technical
service functions.

Exercising time

The length of the exercising session can be
set to between 1 and 60 minutes in all exercis-
ing modes. The default setting in each case is
15 minutes.

Forward/backward automatic

When the Automatic direction reversal func-
tion is active, the exerciser automatically
changes the direction of rotation every four
minutes when the patient is exercising ac-
tively-assisted.
When the patient is exercising actively the di-
rection of rotation is not reversed.

Biofeedback leg exerciser

The purpose of the Biofeedback function is to
provide the patient with feedback about the
progress of the session.
The top part of the screen shows the following
information:
❑
Current resistance/power setting
❑
If a heart rate sensor is connected, the cur-
rent heart rate
❑
The patient's current power output
❑
The current speed of rotation of the cranks
❑
The distance completed
❑
The remaining exercising time.
Symmetry training bars/road:
These two Biofeedback diagrams show how
symmetrically active exercising is being per-
formed, i.e. how great the power difference
between the right and left legs for each direc-
tion of rotation (forwards and backwards, see
page 48).
The bar diagram shows the distribution of
power output between the two sides. The total
of the two bars always adds up to 100 %.
