Question

Which of the following terms is defined as deformation divided by original length? stress strain strength elasticity plasticity In regard to the HMG signal, the is an indicator of the magnitude of muscle activity. Frequency Amplitude Normalization None of the above The EMG signal is based on the action potentials at the muscle fiber membrane. True False The amplitude of the EMG signal is measured in Hz, True False Shaving and cleaning the skin are 2 ways to increase the quality of the EMG signal when performing surface electromyography. True False

Explanation / Answer

21. B (Strain - amount of deformation divided by the original length of the object or by the original angular orientation of the object).

22. B (EMG amplitude recorded is a mix of both direct physiological procedures that create and transmit myoelectricity and a scope of other by implication related factors that likewise influence the qualities of the recording (Kamen and Caldwell, 1996). The span of the EMG amplitude is particularly influenced by noise from the equipment, the encompassing environment, and even the way of the signal itself.)

23. True (the measure of action potential in muscle cells)

24. True ( motor unit action potentials)

25. True (Also by using fine electrodes )
