Hi all,
(i) Is anyone using the Noraxon Telemyo 2400T G2 and 2400R G1? Have you experienced any problems with recordings using this mis-match in generations? In particular we are observing packets of high frequency noise which last a few seconds throughout surface and fine-wire EMG recordings.
(ii) I have collected surface and fine-wire EMG recordings on a treadmill using the above system and have observed very large amplitude high frequency artefacts in the fine-wire recordings which appear to occur at heel contact. Due to its nature the artefact is difficult to remove with filtering. Has anyone observed this problem with fine-wire or treadmill recordings previously and have any advice to offer?
Thank-you,
