1 Exerciser options
1.1 Basic exerciser
THERA-vital
The basic version of the THERA-vital can be
used for passive (driven by the exerciser) and
active (where the motive power is provided by the
patient) therapeutic exercise of the legs. The
patient’s legs are held in the footrests by Velcro
straps. For balance and stability there is also a
handlebar that can be adjusted for height and
angle. All important parameters can be set on the
control pad. The exercising data is displayed on
the colour screen.
The THERA-vital can be fitted with different con-
trol pads:
Control pad with 5.7" colour screen
Control pad with 10.4" colour touchscreen
The function of the THERA-vital is identical
whichever control pad is fitted; the larger screen
and touchscreen functionality offer a greater level
of user-friendliness, however.
THERA-live
The basic version of the THERA-live can be used
for passive (driven by the exerciser) and active
(where the motive power is provided by the
patient) therapeutic exercise of the legs. The
patient’s legs are held in the footrests by Velcro
straps.
The THERA-live is equipped with a hand-held
control pad and a 2" display screen.
1.2 Options
Handlebar (THERA-live only): the adjustable
handlebar provides optimum support and stabil-
ity, especially when exercising actively.
Upper torso exerciser: Instead of the handle-
bar, the THERA-Trainer can be fitted with an
upper torso exerciser. This has a separate motor,
in other words both passive and active exercise
are possible. It is controlled from the same con-
trol pad as on the basic exerciser. The patient
holds onto the therapy grips. When exercising the
legs, the therapy grips are replaced by adapter
handles.
Forearm rests, wrist straps, special Tetra-
Knurled-handles and wrist supports: for more
effective restraint of the lower arms, especially in
cases of partial paralysis, there is a choice of var-
ious optional forearm rests, forearm rest straps,
special Tetra-grips and wrist supports to suit the
particular disability.
Infinitely variable crank length: with the varia-
ble crank length option, the crank length and,
therefore, extent of leg movement can be individ-
ually adapted to the patient without the use of
tools.
Calf rests: the pivoting and vertically adjustable
calf rests help to secure and guide the lower legs,
particularly in cases of partial paralysis.
Foot fixings: The foot fixings are useful for
patients to be able to quickly and easily strap their
own feet into the footrests.
Stabiliser straps, self-operated: the self-oper-
ated stabiliser straps are simply hooked onto the
wheelchair and tightens itself automatically. It
prevents the wheelchair from tipping over when
the patient is exercising with the THERA-Trainer.
Height adjuster: the height adjuster enables the
THERA-Trainer to be adjusted to the height of the
patient's chair/wheelchair.
Cardio-Pulse set (THERA-vital only): the Car-
dio-Pulse set (heart rate monitor with chest strap)
monitors the patient’s precise heart rate with the
aid of a chest strap. The heart rate is displayed on
the colour screen.
THERA-assist (THERA-vital only: the THERA-
assist software is an exercising program for
recording, analysing and documenting exercis-
ing data. A USB memory stick is used to transfer
the data from the exerciser to the computer on
which the software is installed.
Printer for exercising data (THERA-vital
only): the printer can be connected to the
THERA-vital via a Bluetooth connection. It ena-
bles quick and easy documentation of the exer-
cising data.
Control pad with 10.4" colour touchscreen:
the large screen and touchscreen functionality
offer a greater level of user-friendliness.

3 Intended use
The THERA-Trainer is suitable for use in the
home, in hospitals, care institutions and medical
practices. It is intended to improve the mobility of
persons suffering impaired mobility as a result of
accidents, surgical operations or general condi-
tions affecting the mobility of the support and
locomotor systems.
The THERA-Trainer can be used both as a leg
exerciser and as an upper torso exerciser. It is
suitable for passive exercise (where the patient’s
limbs are moved by the machine) as well as
active therapeutic exercise (where the patient
provides the motive power). The transition from
passive to active exercising is gradual. Operating
both upper torso and leg exerciser at the same
time is not possible.
It is not possible to give specific details of the use
of the THERA-Trainer in the case of the various
possible medical conditions or to provide specific
exercise programmes. The possible settings
depend on the individual condition (age, build,
physical constitution, fitness, …) of the patient.
Consultation with a doctor and/or therapist is
advisable.
Static discharge damage warn-
ing: connections marked with
this symbol must not be
touched with fingers or tools.
Make sure you are not carrying
any static charge by touching a
metal part of the exerciser
frame. Finish the exercising
session before connecting a
USB memory stick or other
USB storage device to a USB
interface.
Important information not relat-
ing to dangers to people or

4Safety
Discuss with your doctor or therapist whether
exercising on the THERA-Trainer without an
assistant is advisable.
Before using the exerciser for the first time or
if it has been transported some distance,
leave it to stand for approximately 1 hour at
room temperature.
Only move the THERA-Trainer on its castors
on a firm and level surface (see page 12).
Always place the THERA-Trainer on a level
and non-slip surface so as to ensure maxi-
mum stability. Make sure that the adjustable
stand 2is properly tightened (page 13).
The THERA-Trainer may only be connected
to a power supply matching the specifications
on the rating plate. Only connect the exerciser
to a properly earthed power socket.
The power cord must be routed in such a way
that it does not represent a tripping hazard,
that it cannot become caught up in the cranks
and that it cannot be damaged by other equip-
ment. Never use the exerciser with a dam-
aged power cord. Use only the original power
cord supplied with the exerciser.
To prevent the RISK of electric shock, only
connect the exerciser to an earthed power
supply.
To prevent electric shock, the THERA-Trainer
must never be used in wet, damp or very hot
conditions.
Have your trained supplier or doctor/therapist
show you how to operate the exerciser before
using it for the first time.
Do not wear shoes that have laces when exer-
cising on the THERA-Trainer. The shoe laces
could become caught in the cranks and cause
injury as a result.
Always wear close-fitting clothing when using
the exerciser. Do not wear any jewelry or
accessories that could become caught up in
the cranks of the upper torso or leg exerciser.
If the THERA-vital is to be used by a patient in
a wheelchair, and if it is not possible to be
absolutely certain that the wheelchair will not
tip over backwards (e.g. with spastic or
extremely active patients), wheelchair
stabilisers 3must be used (see page 21).
The THERA-Trainer is designed to be used in
a sitting position only. Never stand on the
footrests 5with the full weight of your body.
Before commencing a leg exercising session,
rotate the footrests by hand (without the
motor) through one full revolution with the
patient’s feet in position and the legs strapped
in to ensure that the cranks can move freely,
that the crank length is correctly set and that
movement of the legs is not restricted (legs
cannot become trapped). Perform a similar
check before using the upper torso exerciser.
Never reach into or attempt to take hold of
moving parts of the exerciser (e.g. cranks,
crank length adjusters, footrests, calf rests,
forearm rests, ...) when it is running.
Before starting an upper torso exerciser ses-
sion, extend the exerciser stand 2at least
10 cm (see page 13).
When exercising with the THERA-Trainer,
make sure that your posture is physiologically
correct. Seek advice from a doctor/therapist.
In cases of partial paralysis, spasticity or
instability of the legs, only use the exerciser
with the optional calf rests 7.
In the case of muscle contractures or limited
joint movement, the infinitely variable crank
length option 4must be used.
The crank length must not be altered when the
motor is running. Do not adjust the crank
length when the patient’s feet are in the foot-
rests. Tighten the locking screw
(see page 14) and check that it is tight before
every exercising session.
Start with an exercising session of no longer
than 15 minutes. You can gradually increase
the length of subsequent exercising sessions
to suit the patient’s individual capabilities.
Start the exercising session with a passive,
motor-powered phase to loosen up.
The greater the distance between the
THERA-Trainer and the patient’s seat/wheel-
chair, the more the knee, hip and arm joints
are extended. Therefore, you should start at a
close distance. Avoid over-extending the
joints.
Before starting a leg exercising session,
adjust the height of the handlebar/upper-torso
exerciser so that the thighs/knees can not
strike any part of the exerciser. Make sure that
the height adjuster (see page 16/ 17) is prop-
erly tightened.

| 8 |
During a leg exercising session, the cranks of
the arm exerciser must be locked in a horizon-
tal position. Otherwise they could trap the
thighs.
The handlebar/upper torso exerciser must not
be used as a support for standing – the exer-
ciser could tip over.
The feet must not be placed in the footrests
during an upper torso exercising session.
The adjustable-length cranks for the upper-
torso exerciser must not be used without addi-
tional protection against shearing.
Make sure that the forearm rests are securely
attached to the cranks/therapy grips (see
page 19) during an upper torso exercising
session. Make sure that the patient's arms
cannot come out of the forearm rests.
If the patient suffers symptoms of illness
brought on by an exercising session, consult a
doctor immediately.
Children must always be constantly super-
vised when exercising on the THERA-Trainer.
Never leave the THERA-Trainer unattended
when there are children present.
The exerciser is only completely discon-
nected from the electrical power supply when
the plug is removed from the power outlet
socket.
Always unplug the power cord before opening
the exerciser casing. Never run the THERA-
Trainer with the casing open or if the casing is
damaged.
Before starting the THERA-Trainer with upper
torso exerciser attached, check that the fore-
arm rests can rotate completely freely.
So as to avoid any safety hazards, when exer-
cising in an ordinary chair, it should be com-
pletely stable and sturdy and should not have
castors.
When exercising in an electric wheelchair, the
electronic controls/wheelchair movement
functions must be switched off.
Exercising with only one footrest is not per-
missible.
When exercising the legs, both feet must be in
the footrests.
Repairs may only be carried out by trained
specialist dealers. If the exerciser is dam-
aged/faulty or if it produces abnormal noises
or smells, stop the exercising session immedi-
ately, unplug the power cord and contact your
trained service engineer.
Never use liquids that contain solvents to
clean the exerciser.
With a short crank length and a high motor
power setting, the patient can be subjected to
very strong forces. Limit the motor power to
the level necessary for the patient and his/her
exercising situation.
During upper torso exercising sessions using
forearm rests on a THERA-vital with 10.4"
screen, make sure that the patient's digits –
especially the thumbs –cannot strike the
screen.
Make sure that the coiled lead for the control
pad (optional feature, THERA-live) does not
fall into the area swept by the cranks. Other-
wise the coiled lead could become caught in
the cranks and cut off.
Only accessories approved by the manufac-
turer (medica) may be connected to the USB
connections.

5 Notes on exercise therapy
5.1 General observations
The object of therapy depends on the medical
condition of the patient and may be aimed at
maintaining mobility (preventative therapy) or at
rehabilitation after an operation, injury or illness,
i.e. at regaining mobility and strength.
We recommend that the THERA-Trainer is used
as part of a planned exercise programme pre-
scribed by a doctor or therapist.
Begin exercise sessions slowly and then
increase the level of intensity gradually to no
more than 70% of the user’s physical capability,
being particularly careful to avoid over-exertion.
5.2 Uses
The THERA-Trainers can be used both as leg
exercisers and as upper torso exercisers.
Using the THERA-Trainer as a leg exer-
ciser: The patient sits on a chair or wheel-
chair. The THERA-Trainer stands on the floor
in front of the patient. If possible the wheel-
chair footrests should be removed or folded to
the side out of the way. The feet are placed in
the exerciser footrests 5and may be further
secured by the calf rests 7or the foot
fixings 15. The leg exerciser is started by
means of the control pad 12 or 16remote
control.
Using the THERA-Trainer as an upper
torso exerciser: The patient sits on a chair or
wheelchair. The THERA-Trainer stands on
the floor in front of the patient. The patient’s
feet are placed on the floor or the wheelchair’s
footrests. The upper torso exerciser is
adjusted to the correct height and reach. The
arms are fixed to the therapy grips, wrist sup-
ports (optional feature), forearm rests
(optional feature) or the special Tetra-grips
(optional feature) (see page 19/ 20). The
upper torso exerciser is then started from the
control pad by an assistant.
THERA-Trainers are specifically recommended
for the following conditions:
Multiple sclerosis (MS)
Strokes, hemiplegia and apoplexy
Paraplegia, tetraplegia and spina bifida
Parkinson’s disease
Skull and brain trauma
Muscular diseases such as muscular dystro-
phy
Cerebral paresis
Cardio-vascular problems
Rheumatic conditions
Arthritis and osteoarthritis
Impaired mobility and ability to walk
General lack of mobility
5.3 Correct posture
Always make sure that the patient’s posture
when exercising with the THERA-Trainer is in
keeping with the purpose of the therapy.
The greater the distance between the THERA-
Trainer and the patient’s chair/wheelchair, the
more the knee and hip or elbow and shoulder
joints are stretched. Therefore, you should start
the exercise programme with the THERA-Trainer
positioned close to the patient’s chair/wheelchair.
When exercising in an electric wheelchair, the
height of the THERA-Trainer should be individu-
ally adjusted to suit. In that way you will avoid
overstretching the joints or damaging mus-
cles/tendons/ligaments.
It is also important to ensure that the
patient’s sitting position in the chair/wheel-
chair is as upright as possible.

| 10 |
5.4 Exercise programme planning
The frequency and duration of exercise sessions
are heavily dependent on the patient's particular
medical condition and should normally be individ-
ually planned and prescribed by a doctor or ther-
apist. Therefore, only general guidance on
exercise programme planning can be given at
this point.
Regular exercising with the THERA-Trainer is
extremely important if improvements in mobility,
and particularly in strength and endurance, are to
be achieved. Short but frequent sessions are bet-
ter than long strenuous ones.
You should therefore start with sessions of no
more than 15 minutes of continuous exercise.
Always start with a period of gentle passive exer-
cise to warm up and then progress to light, active
exercising with a low resistance setting. The
length of the session, the cadence, the amount of
active exercising and the resistance can be grad-
ually increased a small amount at a time.
You can also schedule several exercise sessions
a day – always providing that no negative symp-
toms of illness occur and that the physical capa-
bilities of the patient are not exceeded. The
intensity of the therapy is correct if strength,
endurance and mobility gradually improve and
the patient feels well.
5.5 Active and Passive exercising
Active exercising means that the patient uses
his/her own efforts and energy to turn the
machine’s cranks against the set resistance level
(see the section “Resistance/Power demand” on
page 24).
The THERA-vital offers the patient a number of
options for active exercising:
Resistance demand: the patient exercises
against a set resistance level (see page 24).
Power demand: the patient works at a con-
stant power output level (measured in watts).
The resistance is automatically adjusted
according to the pedalling speed (see
page 24).
Heart rate limit: the patient exercises up to a
level of intensity defined by a heart rate limit. If
the patient’s heart rate rises above the set
limit, the resistance is automatically lowered.
This function requires the optional Cardio-
Pulse set.
Speed demand: A required cadence (pedal-
ling speed) is set that is then held constant by
the THERA-vital throughout the exercising
session. The patient can thus make a physical
effort by actively pushing on the pedals with-
out having to co-ordinate the effort with the
speed of rotation (see page 24).
Passive exercising means that the patient’s
limbs are moved by the exerciser without any
effort on the part of the patient. The motive power
is provided by the THERA-Trainer.
When first switched on, the THERA-Trainer
always starts with a passive exercising phase
with a preset cadence. When the patient starts
actively exercising with the same motion, the
THERA-Trainer automatically changes over to
active exercising mode.

| 11 |
5.6 Muscle hypertonia/spasms
Muscle hypertonia can generally be reduced by
gentle and even circular motion on the THERA-
vital.
The important consideration is that the distance
between the THERA-Trainer and the patient’s
chair/wheelchair is kept as small as possible. If
this is combined with an upright sitting position
and a short crank length (see “Adjusting crank
length” on page 14), a reduction in the muscle
hypertonia can generally be observed within a
short time. Experience has shown that this effect
can last for several hours.
In consultation with a doctor or therapist, an exer-
cise programme should be drawn up so as to
achieve the correct “degree” of hypertonia reduc-
tion. If a spasm (= sudden, involuntary increase in
muscle tightness) occurs while exercising, the
electronic circuitry of the THERA-Trainer detects
it and immediately stops the motor – assuming
the anti-spasm function has been activated (fac-
tory setting).
When a spasm occurs, the THERA-Trainer stops
and then continues to rotate forwards after a
short delay (factory setting). That forward rotation
stretches the muscles and allows the spasm to
recede. Depending on the individual require-
ments, the direction of rotation after a spasm is
detected can be changed:
THERA-vital: Submenu, Spasticity program,
see page 35
THERA-live: Permanently changing factory
settings, see page 31
5.7 Side effects
In rare cases, exercising on the THERA-Trainer
can cause undesirable side effects such as:
an increase in pain in some cases
over-reduction of muscle tone in some cases
skin injuries (e.g. pressure ulcers)
However, in our many years of experience, we
know of virtually no side effects occurring.

| 12 |
6 Transporting and commissioning
6.1 Before using for the first time
Remove the THERA-Trainer from the packaging
and check for any signs of damage that may have
occurred in transit. Also check that the power
supply voltage specified on the rating plate
matches that of your mains power supply.
If you discover any damage or if the power supply
voltage is incorrect, you should contact your sup-
plier immediately.
6.2 Transporting
The THERA-Trainer is fitted as standard with
castors for the purposes of transporting. To move
the exerciser, tip it as shown and push it in front
of you or pull it behind you.
You can also pull the THERA-Trainer closer to
you when sitting in a chair/wheelchair so as to
obtain the best distance from the machine when
exercising. Tip the THERA-vital towards your
chair/wheelchair so that it is balancing on its cas-
tors. Then pull it towards you until it is at the right
distance.
Without the handlebar/upper torso exerciser fit-
ted, the THERA-live is easy to carry using the car-
rying grip. Take hold of the exerciser by the
carrying grip with one hand and under the motor
casing with the other.
6.3 Connecting to the power supply
Connect the THERA-Trainer to the power outlet
socket using the power cord. The exerciser is
then ready for operation. You can start it from the
control pad.
6.4 Switching the exerciser on/off
(standby mode)
As soon as the power supply is connected, the
THERA-Trainer is ready for operation and an exer-
cising session can be started (see page 24/ 28).
If no button is pressed on the THERA-Trainer for
more than a certain period of time, the exerciser
goes into standby mode. That is evident from the
display:
On the THERA-vital, the screen backlighting
switches off.
On the THERA-live the backlighting on the
control pad switches off and the display
shows three lines.
Pressing any button brings the THERA-Trainer
out of standby into normal operating mode. The
screen lights up and, following a self-test lasting
a few seconds, the THERA-Trainer is ready for
use.
The wheels are not suitable for moving
the exerciser over uneven surfaces or
unsurfaced ground.
▶The exerciser must be carried up or
down steps. This requires at least
two persons.

| 13 |
7Operation
7.1 Adjusting the exerciser stand
The THERA-Trainer can be given greater stability
by extending the stand. It is imperative that the
exerciser stand is extended, especially for upper
torso exercising.
▶Tip the THERA-vital on its rear bottom edge.
▶Undo the two fixing screws using the tool sup-
plied.
▶Extend the exerciser stand taking care not to
exceed the maximum extension marked on
the stand (12 cm).
▶Retighten the fixing screws.
▶Tip the THERA-vital forwards again into its
normal position.
▶To level the THERA-vital on an uneven floor,
the rubber feet on the exerciser stand can be
adjusted (except with adjustable legs option).
▶Undo the lock-nut with an open-ended span-
ner (size 10 mm) and unscrew the rubber foot
until the THERA-Trainer stands firmly.
▶Re-tighten the lock-nut.
7.2 Footrests
The footrests are designed for exercising with or
without shoes.
The feet can be securely fixed in the footrests
with the Velcro straps provided. To do so, pull the
Velcro strap over the top of the foot to the outer
side of the footrest and press it against the Velcro
strip.
Before every exercising session, check that your
feet are correctly positioned in the footrests and
are securely held by the Velcro straps.
7.3 Adjusting crank length, 2-posi-
tion cranks
The THERA-Trainers are fitted as standard with
cranks that have 2 length settings. They can be
adjusted by a technically competent person.
Using a 6 mm Allen key, the crank length can be
set to the suitable position. Please note that the
right-hand crank has a right-hand thread
(unscrewed by turning anticlockwise) and the
left-hand crank a left-hand thread (unscrewed by
turning clockwise). Make sure you tighten the
screws properly again after changing the crank
length.
The 2-position cranks are not suitable for fre-
quently changing the crank length. Optional infi-
nitely variable cranks are available for such
cases.
Do not wear open shoes when exercis-
ing on the exerciser. If shoes with open
heels are worn, the feet can slip back-
wards out of the footrests.
▶Do not wear shoes with laces. The
shoe laces could become caught in
the cranks and cause injury as a
result.
Exercising must only ever be under-
taken with both footrests fitted.

7.4 Infinitely variable crank length
(optional feature)
If the exerciser has the optional infinitely adjusta-
ble cranks, the crank length can be infinitely
adjusted. Thus the degree of movement can be
adjusted individually to suit each patient’s mobil-
ity.
▶Switch off the THERA-Trainer by pressing the
“STOP” button.
▶Unplug the power cord.
▶Remove the feet from the footrests.
▶Undo the variable-crank locking screw.
▶Slide the footrest along the crank to the
desired position and firmly tighten the lock-
ing screw.
▶Adjust the opposite crank in the same way.
Make sure that both cranks are set to the
same length (the cranks are marked with a
scale to facilitate adjustment). In certain
cases, it may be beneficial for therapeutic rea-
sons to have different crank lengths on each
side (e.g. if the patient’s legs are different
lengths or have different degrees of mobility).
If the crank length needs to be changed fre-
quently (e.g. in hospitals, medical practices,
etc.), infinitely variable cranks with T-bar Allen
key are available as an option.
7.5 Foot fixings (optional feature)
The foot fixings allow the feet to be secured in the
footrests quickly, safely and in many cases by
the patient.
To secure the foot in the footrest:
▶Press the locking button on the foot fixing.
The retainer strap will spring open.
▶Place the foot in the footrest.
▶Close the foot fixing so that it holds the foot
securely without being too tight.
If the crank lengths are set differently on
each side, no useful analysis of symmetry
is possible when using the Bio-feedback
function.
Exercising must only ever be under-
taken with both footrests fitted.
Risk of injury:
▶Only fasten/unfasten the foot fixings
while the THERA-Trainer is not run-
ning.

| 15 |
To undo the foot fixing:
▶press the retainer strap down slightly while
pressing the locking button on the foot fixing.
▶Let go of the retainer strap while still pressing
the locking button.
The retainer strap will open so that the foot
can be removed from the footrest.
7.6 Calf rests (optional feature)
The calf rests help to secure the legs in cases of
paralysis. They are connected to the footrests by
a pivoting joint so as not to impair movement of
the ankles.
Fitting the calf rests
The pivoting arm for attaching the calf rest is inte-
grated in the footrest.
▶Fold the pivoting arm upwards.
▶Undo the knurled-handle screw on the calf
rest and pass it through the slot in the pivoting
arm.
▶Secure the calf rest by tightening the knurled-
handle screw.
The pad on the foot fixing is attached by a
Velcro strap.
▶Position the pad so that it fits the
foot/shoe as snugly as possible.
Risk of injury:
▶if the calf rests are not used, the piv-
oting arms must be folded out of the
way. They are held in that position by
a magnet behind the footrest.
Positioning the calf rests
▶Adjust the height of the calf rests so that the
cups fit around the calves. Secure the lower
legs with the Velcro straps.
Make sure that patients whose legs are
held in the THERA-Trainer by Velcro
straps are able to undo the straps on
their own or else can always call on the
assistance of another person.

7.7 Adjusting the handlebar
(optional feature on THERA-live)
If you wish to exercise actively but suffer from
muscle hypertonia or a lack of abdominal stabil-
ity, the handlebar provides extra stability and bal-
ance. You can adjust the handlebar position to
suit your individual size and sitting position.
Height adjustment is effected by means of a
locating pin and clamp function:
▶Loosen the knurled-handle screw on the sup-
port tube by turning it anticlockwise (approx.
one turn).
▶Take the weight off the locating pin by lifting
the handlebar upwards.
▶Pull out the locating pin and move the handle-
bar to the desired height.
▶Allow the locating pin to snap into position and
tighten the knurled-handle screw by turn-
ing it clockwise.
▶If you wish to adjust the handlebar horizon-
tally, you must slightly loosen the eight screws
using the tool supplied.
▶Move the handlebar to the desired position
and then retighten the screws.
Risk of crushing:
When sliding the tubes together, it is pos-
sible for your hand to become trapped.
▶When adjusting, take hold of the
handlebar by the handle at the top
and not by the adjustable tube.
Do not withdraw the handlebar out of
the handlebar/upper torso exerciser
support tube any further than the mini-
mum insertion mark. No more than half
of the STOP label should be visible..
Set the handlebar position so as to obtain
as upright an exercising position as possi-
ble.

exerciser, the cranks must be unlocked
(see page 18).
The upper torso exerciser should be
adjusted so as to obtain as upright an exer-
cising position as possible. The crank
spindle should be roughly at shoulder
height.
▶Consult your doctor or therapist as to
the best position for the upper torso
exerciser.
Adjust the upper section to a height at
which the thighs/knees cannot strike the
upper torso exerciser at any point.
Risk of crushing:
When sliding the tubes together, it is
possible for your hand to become
trapped.
▶When adjusting, take hold of the
upper torso exerciser by the handle
at the top and not by the adjustable
tube.
Do not withdraw the upper torso exer-
ciser out of the handlebar/upper torso
exerciser support tube any further than

the arrester knob audibly snaps into position.
It should now not be possible to rotate the
cranks.
▶To unlock the cranks, pull the arrester knob
downwards, turn it a quarter turn and let it go.
7.8.3 Therapy grips for upper torso exer-
ciser
The therapy grips offer a variety of holding positions
for the hands. The therapy grips should only be used
for upper torso exercising if the patient is capable of
gripping them sufficiently well and securely.
To fit the exercising grip:
▶press in the locating pin on the exercising grip
and carefully slide the exercising grip onto the
crank spindle and push it fully home.
▶Now release the locating pin. The exercising
grip should snap audibly into position.
▶Repeat the operation with the second exercis-
ing grip.
To remove the exercising grip:
▶press in the locating pin and pull the exercis-
ing grip off the crank spindle.
▶Repeat the operation with the second exercis-
ing grip.
To use the upper torso exerciser with
adapter handles as a handlebar, the
cranks must be locked by means of the
arrester knob (see following section).
The adapter handles are not designed
to support the full weight of the body or
for carrying the exerciser.

7.9 Forearm rests (optional feature)
The purpose of the forearm rests is to help
patients with symptoms of paralysis, muscle
hypertonia, spasms or lack of hand/arm mobility
to obtain a secure hold.
Apart from the forearm rests for the therapy grips,
all forearm rests can and should be individually
adjusted. Combinations of forearm rests are also
possible, as is the use of only one forearm rest.
Adjustment by a doctor or therapist is essential.
Elastic Velcro straps allow the forearms to be
secured in the forearm rests.
You can either
▶place the arm in the forearm rest after the fore-
arm rest has been attached to the upper torso
exerciser
-or-
▶fix the forearm rest to the arm first and then
slide the forearm rest onto the spindle on the
crank.
