Neurology is the clinical medical discipline that is concerned with treating patients with nervous system and muscular disorders.

What exactly is neurology?
A neurologist is a specialist in the medical field that deals with diagnosing and treating nervous system conditions.
After having established a detailed history, the neurologist performs a clinical neurological examination in order to assess the patient's behaviour, speech, orientation status, memory, muscle strength, sensation, coordination, ability to perform skillful movements, balance, gait, and other nervous system characteristics.
Based on the patient's medical history and neurological examination at the clinic, the doctor identifies the condition and prescribed diagnostic tests such as computed tomography (CT), magnetic resonance imaging (MRI), jugular vein ultrasound (Doppler sonography), electromyography (EMG), electroencephalography (EEG), autonomic nervous system function test, and blood tests.

The most common symptoms and signs that lead patients to the neurology clinic include, among other, headaches, back and muscle pain, dizziness, gait and motor issues, and mental decline.

Electrodiagnostic testing of the peripheral nervous system is extremely useful in the management of peripheral nervous system disorders and diseases.
The electrodiagnostic testing of the peripheral nervous system will shed more light on the state as well as the condition.

if not already previously detected in a clinical investigation, it is rare for such an examination to actually reveal a nerve or musculoskeletal defect.However, without a doubt, EMG refines observation conditions and allows for a more accurate diagnosis.
Electromyography (EMG) is an important neurophysiological investigation method used to recognize peripheral nerve and muscle impairment.
The oscilloscope displays the muscular electrical activity in wave form.
The wave shape and intensity can be used to determine the disease location; furthermore, this technology can also be used to monitor the keep track of the success of treatment.
There is, however, an exception when the patient is referred for therapy exclusively, in which case the examination is performed using needles.
If the patient is suitably referred for an electromyographic examination, new information relevant to his or her treatment, or to better assess the disease prognosis, may be obtained.
Electromyography of the Upper and Lower Extremities
Electromyography of the Upper and Lower Extremities
Motor neurons transmit electrical signals from the central nervous system to the muscles. Damaged or diseased muscle fibers do not function properly or do not respond appropriately to nerve impulses.
Electromyography of the upper and lower extremities
If motor nerves are damaged or diseased, they may send abnormal electrical signals to the muscles. Electromyography (EMG) converts these impulses or signals into graphs and numerical data that help the physician establish a diagnosis.
Patients are referred for electrodiagnostic testing when there is suspicion of carpal tunnel syndrome (median nerve or ulnar nerve involvement), cubital tunnel syndrome (ulnar nerve), radiculopathy (compression of a spinal nerve root), polyneuropathy (systemic disorders affecting multiple peripheral nerves), or mononeuropathy (damage to an individual peripheral nerve).
Before the examination, it is important that patients inform the physician about all medications they are taking, including over-the-counter drugs. They should also mention if they have a bleeding disorder or a cardiac pacemaker. In some cases, the presence of these conditions may mean that an EMG examination cannot be performed or may require special precautions.
The examination is carried out in a neurophysiology laboratory by a specialist physician with the assistance of a neurophysiology technician. It consists of two parts: a nerve conduction study (NCS) and needle electromyography (needle EMG).
The nerve conduction study measures the strength and speed of electrical impulses as they travel along the nerves. The physician places a recording electrode on the skin over the nerve or nerves being examined and positions a second electrode approximately 20 millimetres away. This stimulating electrode delivers low-voltage electrical pulses that activate the nerve. As the impulse travels along the nerve, the recording electrode detects the electrical response and transmits it to a computer for analysis. Once the test is complete, the electrodes are removed.
The second part is the needle EMG examination. The physician first cleans the area with an antiseptic and then inserts fine needle electrodes directly into the muscle tissue. Needle EMG evaluates how well the affected muscles respond to electrical impulses. The needle electrodes detect the muscles' electrical activity both at rest and during contraction. This activity is displayed on an oscilloscope (a monitor that shows electrical activity as waveforms). An audio amplifier may also be used so that the electrical activity can be heard. During muscle contraction, the sound is often described as resembling hail falling on a metal roof.
During both components of the electromyography examination, electrodes transmit small electrical signals to the nerves. A computer converts these signals into graphs and numerical values, which the physician interprets to establish a diagnosis.
The entire examination typically takes 30 to 60 minutes. In most cases, the physician reviews the results with the patient immediately after the procedure. If the muscles are healthy, the EMG will detect very little electrical activity while the muscle is at rest.
