Electrolyte balance refers to the regulation of electrolytes—ions such as sodium, potassium, chloride, and bicarbonate—in the body. These ions are crucial for maintaining fluid balance, nerve function, and muscle activity. In psychology, electrolyte balance can influence cognitive function, mood, and overall mental health. Imbalances can lead to conditions such as dehydration, confusion, or even severe neurological disorders.

An Electromyograph (EMG) is defined as a test which measures muscle response to nerve stimulation. It is used to evaluate muscle weakness and to determine if the weakness is related to the muscles themselves or a problem with the nerves that supply the muscles.

refers to measurement of muscle tension through electrical sensors at skin surface

Electromyography refers to a method utilizing either surface electrodes or fine wire/needle electrodes to detect the action potentials of muscles and provide an electronic readout of the contraction intensity and duration.
