Electroencephalogram (EEG) finds problem related to the electrical activity of the brain. EEG tracks the brain wave patterns.
Electromyography (EMG) assesses the health of the nerve cells (motor neurons) that control the muscles. Motor neurons transmit electrical signals that causes muscles to contract.
Nerve Conduction Velocity (NCV) unlike EMG uses electrodes that is taped to the skin to measure the speed and strength of signals travelling between two or more points. NCV uses tiny devices to transmit to detect electrical signals and reveal nerve dysfunction.
Pulmonary function tests (PFT) is majorly to assess the strength and functional efficiency of lungs along with the volume of air that circulates in the respiratory system. Patients who suffer from breathing problems, asthma and breathlessness can undergo this test.
