Introduction
Nerve conduction studies can assist in diagnosing diseases such as hypertension, myelitis, trigeminal neuralgia, peripheral neuritis, and muscular atrophy. This test evaluates the conduction of nerve impulses along nerve fibers and is primarily used to assess nerve function. However, it should be noted that if abnormal results are detected, further diagnostic analysis should incorporate findings from other tests.
Generally, nerve conduction refers to the process of nerve impulses transmitted through nerve fibers. Nerve conduction studies can be used to diagnose diseases such as hypertension, trigeminal neuralgia, peripheral neuritis, myelitis, and muscular atrophy. If experiencing any discomfort, timely medical consultation is recommended. Detailed analysis is as follows:
1. Hypertension
Hypertension may be associated with factors such as family genetics and high sodium diet. Patients typically experience symptoms like headache and dizziness. As the condition progresses, it may affect nerve conduction, and the examination may reveal decreased muscle strength and hyperactive tendon reflexes.
2. Trigeminal Neuralgia
Trigeminal neuralgia may be caused by local inflammation or trauma. When the nerve is compressed, pain in the trigeminal nerve area occurs, typically described as sharp or burning sensations. On palpation, patients experience pain, and nerve conduction studies may show slowed conduction velocity and reduced amplitude.
3. Peripheral Neuritis
Peripheral neuritis is often associated with factors such as heredity and abnormal immunity. When peripheral nerves are affected, patients may experience symptoms such as sensory abnormalities and limited mobility. Nerve conduction studies may show reduced muscle strength and weakened or absent tendon reflexes.
4. Myelitis
Myelitis may be associated with factors such as infection and trauma. Common symptoms include sensory disturbances and motor dysfunction. Patients undergoing nerve conduction studies may show weakened or absent tendon reflexes.
5. Muscular Atrophy
Conditions such as neurogenic muscular atrophy and myogenic neuromuscular atrophy are usually associated with factors like muscular dystrophy and peripheral nerve lesions. The main manifestations include reduced muscle volume and weakened muscle strength. These examinations usually indicate decreased muscle strength, reduced muscle tone, and changes in muscle morphology.
It should be noted that nerve conduction studies can only provide preliminary diagnosis of the aforementioned diseases but cannot confirm them. Therefore, after detecting abnormalities, further diagnosis should combine clinical symptoms and other tests to ensure timely treatment.
