[Temporal muscle fatigue studied via muscle conduction velocity technics and spectral analysis of the electromyographic signal].
We examined 6 normal volunteers (3 males and 3 females, age 26-30). They were requested to clench as hard as they could until they felt pain. The experiment was repeated one hour later. Emg was recorded during the fatiguing exercise and the recovery period. We couldn't determine the muscle conduction velocity, probably because of the anatomy of the temporal muscle. The mean of the power spectrum showed wide variability and proved unsuitable for clinical applications, both for diagnosis and follow-up.
