CHAPTER 2
1. Carefully read this user manual in full before starng up the THERA-Trainer
lyra and carefully note the warnings included inside.
2. Make this user manual available to all individuals who will be operang the
THERA-Trainer lyra.
3. Only qualied service personnel are allowed to install the THERA-Trainer lyra.
4. The use of mulple sockets is not permied.
5. An extension cable of a maximum length of ve metres may be used.
6. To reduce the risk of electric shocks, water must never come into contact with
any of the electrical components, including the motor, power cable and

7. When you press the release buon, the plate bindings start moving. Ensure
that no one is standing on or next to the plate bindings, otherwise there is a
risk of injury.
8. When using the body weight support feature, always ensure that the weight
of the paent is evenly distributed across both bar hooks by using an approved
harness system (see chapter 6).
9. Do not li or lower any load that is not evenly distributed.
10. Set the bar to the correct height (see chapter 5.3.2).
11. Never use the body weight support with just one hook.
12. The harness system is a safety device to prevent the paent from falling. Even

mes and aached to the bar. In these cases, set a minimal body weight
support weight and turn the crank unl the cable is under slight tension.
13. The rope must be pulled out up to the red marking maximum. If you pull out
the rope more there is a risk of wrong winding the rope. The brake acon will
be lost.
14. If the paent cannot be secured correctly on the plate bindings, e.g. if their
shoes are too large or too small for the bindings, the training session cannot
be carried out.
15. Ensure that the foot bindings are rmly fastened for the enre duraon of
the therapy session.
16. Ensure that there are no loose shoelaces, foot-binding and clothing es or
straps for the enre duraon of the therapy session, as these may get caught
in the plate bindings or in the plate binding openings in the casing.
17. The selecon and use of a specic harness system is the sole responsibility
of the medical professional.

THERA-Trainer lyra – User manual CHAPTER 5
5.3 Body weight support
The body weight support feature enables training for paents who cannot (yet)
carry their own body weight. The body weight support feature can be set to be
either dynamic or stac. For the dynamic body weight support feature, the
supported weight swings with the vercal shi of the body as the paent walks,
giving him constant support set to the required weight in all gait phases. In the
stac opon, the supported body weight does not swing along with the movements.
Depending on the gait phase, the paent is either given support equal to the
required weight or more (up to his or her full body weight).
The amount of body weight support depends on the weight and funconal
impairment of the paent. Weight support can be set to 10 to 60 kg.
The light spot on the display indicates the amount and type (dynamic/stac) of
body weight support selected.
5.3.1 Amount of body weight support
1. Set the amount of weight support by turning the handwheel.
2. The light spot on the display indicates the amount of weight support selected;
it can be moved along the weight scale with the handwheel. Set the amount
of weight support for the paent. If, for example, the light spot is under the
55 mark, the paent will be given weight support of 55 kg.
Please note: If the paent’s enre body weight is supported,
the paent’s feet may lose contact with the plate bindings
and hang in the harness system.
Please note: A clockwise turn increases the body weight
support, whereas an an-clockwise turn reduces it.
Warning: When using the body weight support, always
ensure that the weight of the paent is distributed evenly on
both bar hooks by means of an approved harness system (see
chapter 6). Do not li or lower any load that is not evenly
distributed. Never use the body weight support with just one
hook.

THERA-Trainer lyra – User manual
CHAPTER 5
5.3.2 Type of body weight support
The type of body weight support is set by adjusng the height of the bar. To set
the bar to the correct height, the paent must wear the harness system, stand
upright on the plate bindings and aach the harness system to the bracket.
1. Set the height of the bar by turning the crank. The light spot on the display
indicates the vercal height adjustment of the bar.
2. To select the dynamic weight support feature, turn the crank unl the light
spot is in the central area of the display, i.e. on the weight scale. To select the
stac weight support feature, turn the crank unl the light spot is in the upper
area of the display.
Warning: When using the body weight support, always
ensure that the weight of the paent is distributed evenly on
both bar hooks by means of an approved harness system (see
chapter 6). Do not li or lower any load that is not evenly
distributed. Never use the body weight support with just one
hook.
Please note: A clockwise turn raises the bar, whereas an an-
clockwise turn lowers it.
