4.2 Safety
4.2.1 Safety concept
The OMEGO
®
Basic is a mechatronic therapy system used for the rehabilitation of all gait-
relevant bodily functions.
The 2 separate motors are centrally controlled by the software installed on the PC. In
order to preclude the exertion of strong forces during therapy (e.g. in case of sudden
spasticity) or too big a range of motion on the patient several safety measures have been
put in place:
• The motors’ separate speed is limited to a maximum of 80 RPM.
• During therapy, the forces exerted on the motors are being constantly
measured so they can be switched off immediately in case the limit is exceeded.
• For the foot drop therapy, there are clearly separated mechanic foot
connections that limit the maximum force exerted on the patient by means of
a magnetic coupling. In case the magnetic force limit (> 70N) is exceeded, the
foot will automatically be released from the foot rest.
• The device has an emergency shutdown button for cases of unpleasant or
(seemingly) risky situations during therapy. By activating the emergency
shutdown function the motors will be deactivated, and the software will display
the message “The Emergency-button has been pressed”.
• A continuous supervision of the therapy by a therapist or physician is
recommended in any case.
The patient’s suitability for OMEGO
®
Basic is to be assessed by the
treating physician or therapist.
The suggested therapy duration is approx. 30-60 min/day but the
actually permissible duration is highly dependent on each patient’s
general condition and capacity and thus has to be assessed
individually.
Prior to therapy the treating physician or therapist has to assess if and
how long the patient can manage independently, taking into
consideration the patient’s cognitive capacities as well as the general
condition.
