Question

Whose measurements are important for myoelectric control of prosthetic devices?

(a) VCG

(b) ECG

(c) EEG

(d) EMG

The question was asked in an interview for internship.

I need to ask this question from Measurement of Respiration Rate in section Patient Monitoring System of Biomedical Instrumentation

Answer 1

Correct answer is (d) EMG

The explanation is: EMG measurements are also important for the myoelectric control of prosthetic devices (artificial limbs). This use involves picking up EMG signals from the muscles at the terminated nerve endings of the remaining limb and using the signals to activate a mechanical arm. This is the most demanding requirement from an EMG since it depends on the working of the prosthetic device.
