WS6.4. Demonstration of SFEMG technique

A healthy subject will be examined with SFEMG in the frontalis muscle. First slight voluntary activation and then with electrical stimulation. Concentric needle electrodes will be used. Potential pairs of good and non-acceptable quality will be shown and comments will be made on pitfalls particularly in stimulation SFEMG. Remarks on criteria for signal acceptances will be made and a few examples of post-processing will be given.
