Inter electrode distance
'Inter electrode distance' is defined as the centre to centre
distance between the conductive area's of 2 bipolar electrodes.
The influence of the inter electrode distance on the pick-up
area and crosstalk is a relevant item in literature.
SENIAM recommendations
for inter electrode distance
The SENIAM recommendations for sensors restrict to bipolar
sensors only. 'Inter electrode distance' is defined as the
centre to centre distance between the conductive area's of
2 bipolar electrodes.
SENIAM recommends to apply the bipolar SEMG electrodes around
the recommended sensor location with an inter electrode distance
of 20 mm. When bipolar electrodes are being applied on relatively
small muscles the inter electrode distance should not exceed
1/4 of the muscle fibre length. In this way unstable recordings,
due to tendon and motor endplate effects can be avoided.
