    Rectification is the translation of the raw EMG signal to a signal with a single polarity, usually positive. The purpose of rectifying the signal is to ensure the signal does not average to zero, due to the raw EMG signal having positive and negative components. Two types of rectification are used: full-wave and half-wave rectification. [27]

    Accurate differentiation of PD from any other neurological disorder and the identification of the disease course is important in establishing an appropriate antiparkinsonian therapy. In the diagnostic role, surface EMG is a very informative method used to obtain relevant quantitative characteristics. [citation needed]

  4. Bioamplifier - Wikipedia

    en.wikipedia.org/wiki/Bioamplifier

    The EMG signals are acquired from the electrodes applied over or nearby the muscles to be monitored. The electrodes delegates signals to the amplifier unit, usually consisting of high performance differential amplifiers. The usual types of the signal of the interest are in the range of 0.1–2000 mV amplitude, over a bandwidth of about 25–500 Hz.

    EEG, ECG, EOG and EMG are measured with a differential amplifier which registers the difference between two electrodes attached to the skin. However, the galvanic skin response measures electrical resistance and the Magnetoencephalography (MEG) measures the magnetic field induced by electrical currents ( electroencephalogram ) of the brain.

  6. Electromyoneurography - Wikipedia

    en.wikipedia.org/wiki/Electromyoneurography

    Electromyoneurography is a technique that uses surface electrical probes to obtain electrophysiological readings from nerve and muscle cells. The nerve activity is generally recorded using surface electrodes, stimulating the nerve at one site and recording from another with a minimum distance between the two.

  7. Neuromechanics - Wikipedia

    The signal source refers to the location at which the EMG electrode is place. EMG signal acquisition is dependent on distance from the electrode to the muscle fiber, so placement is imperative. The transducer used to detect the signal is an EMG electrode than transforms the bioelectric signal from the muscle to a readable electric signal. [10]

    The doctors and nurses didn’t believe Tomisa Starr was having trouble breathing. Two years ago, Starr, 61, of Sacramento, California, was in the hospital for a spike in her blood pressure.

  9. Event-related potential - Wikipedia

    en.wikipedia.org/wiki/Event-related_potential

    The random brain activity together with other bio-signals (e.g., EOG, EMG, EKG) and electromagnetic interference (e.g., line noise, fluorescent lamps) constitute the noise contribution to the recorded ERP. This noise obscures the signal of interest, which is the sequence of underlying ERPs under study.
