Electroencephalography (EEG) is the recording of electrical activity along the scalp. EEG measures voltage fluctuations resulting from ionic current flows within the neurons of the brain. EEG helps in diagnosis of tumors, stroke and other focal brain disorders.

Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated. The signals can be analyzed to detect medical abnormalities, activation level, or recruitment order or to analyze the biomechanics of human or animal movement.

Treadmill Test (TMT) is done to find the stress on the heart. On the machine the patient walks and the readings are taken. Treadmill Test machine from GE Marquette (USA) for stress test of heart. Treadmill is a device used for exercise testing. The subject walks on a motorized belt, the speed and gradient of which can be adjusted. The blood pressure is measured and entered in the console by the operator. The test is conducted in the medical setting by a trained technician with resuscitatory equipment at hand in case of any untoward events.
