3.4 OPTOGAIT ELECTROMYOGRAPHY CONNECTOR
OptoGait can be used as a simple and non-invasive support for connection to EMG
(Electromyography) devices. The OptoGait digital outputs (or alternatively analogue) can be used as
“virtual footswitches”, completely eliminating the need for contact sensors on the sole of the
patient's foot.
This is a significant leap forward in terms of patient preparation speed and data reliability. The
correlation of EMG data with the Gait Analysis data supplied by OptoGait provides a complete
picture of the patient very quickly, on any natural surface or treadmill.
The OptoGait interface is equipped with a specific connection to enable the link with the EMG
device. The default connector on the connecting cable is a LEMO connector on the interface side
and a 3 poles 3.5mm Mini Jack on the EMG side. If you need another connector, please contact
Microgate.
Please note that the transmission of the impulses has a fixed delay of 300 milliseconds. To ensure
data accuracy, your EMG software will need to take this delay into account.
Also note that the OptoGait software must be run regularly even if the user does not need it. In
example, if the user wants to perform an EMG on a treadmill, the OptoGait software will need to be
set to perform a test on a treadmill (of the desired duration) and the test will need to be started and
stopped regularly to ensure that the impulses are assigned to the correct feet and that the error
filters are working properly. This of course also enables to perform EMG and gait analysis at the
same time.
