Example sentences for: semg

How can you use “semg” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • MF decreases in all cases (both SEMG and MMG, both muscles, all subjects) from the very beginning of the muscle contraction.

  • RMS: The RMS of the SEMG signal is considered the most reliable parameter in the time domain [ 19 ] . An increase of the SEMG RMS with advancing fatigue has been reported in many cases [ 20 21 ] . RMS is claimed to be not affected by the cancellation due to the motor unit action potential train superposition, which affects other processing techniques involving rectification [ 19 ] . It is also related to the power of the signal via the Parseval's relation [ 22 ] , thus providing a direct connection with the frequency domain:

  • Fatigue is associated with a compression of the PSD of the SEMG toward lower frequencies, from the very beginning of the voluntary contraction [ 5 ] . This is due to the reduction in the conduction velocity in direct relation with the muscular fiber membrane excitability and with neural adaptations, resulting in an increase of the lower frequency content of the signal.

  • In all cases (Figure 11- SEMG, Figure 13- MMG, both muscles) the average slope (a1) of the RMS evolution is positive.

  • From (2) it follows that the overall average activity observed through the PSD of a certain SEMG segment, is expressed by the RMS value computed on the same specific SEMG segment of data.
