The footswitch channels are supplementary to the 16
electromyographic channels.
Refer to § “Acquisition unit” for the list of probe combinations
possible in case of acquisition also with EGN.
Electrogoniometers (optional)
The electrogoniometer is an easy to use device that allows the measurement
of joint angle progress over time.
There are primarily two types of electrogoniometers: the potentiometer
and the strain gauge. BTS FREEEMG 300 uses the strain gauge
electrogoniometer of Biometrics LTD.
There are single-axle models for the neck (axial rotation) and the forearm
(prone-supination) and biaxial models for other main joints: wrist, elbow,
knee, ankle, hip and back.
The strain gauge electrogoniometers are made up of two sensors, connected
to each other, that are fixed to the bone segments involved in the joint to
value.
The measure of the angle is provided by the relative angle between the
axes of the two sensors and, unlike the potentiometric electrogoniometers,
