Electromyography Primarily Detects What Types of Diseases?

Electromyography (EMG) is a diagnostic procedure mainly used to evaluate the health of peripheral nerves and muscles. It plays a crucial role in identifying various nerve-related conditions such as acute and chronic demyelinating diseases, Guillain-Barré syndrome, diabetic peripheral neuropathy, peripheral neuritis, and other forms of nerve inflammation.

Muscle Disorders That EMG Can Detect

In addition to nerve issues, EMG is also highly effective in diagnosing muscle disorders. Conditions like myositis, dystonia, and other forms of muscle dysfunction can be accurately assessed using this technique. By measuring the electrical activity in muscles, doctors can determine whether the problem originates in the muscle tissue itself or in the nerves controlling them.

EMG for Nerve Injury Assessment

Patients suffering from brachial plexus injuries, trauma, fractures, or unexplained weakness often undergo EMG to determine if there is any underlying nerve damage. This test helps physicians understand the extent of the injury and guides them in planning appropriate treatment strategies.

Role of EMG in Neurological and Spinal Conditions

Electromyography is also commonly used in diagnosing more complex neurological conditions such as amyotrophic lateral sclerosis (ALS), anterior horn cell disorders, and lumbar spine-related diseases. These conditions can cause progressive muscle weakness and atrophy, and EMG provides essential data to support early and accurate diagnosis.

In summary, electromyography is a versatile and valuable diagnostic tool used across multiple medical specialties. Whether for evaluating nerve conduction, muscle function, or spinal health, EMG remains an essential test for identifying a wide range of neuromuscular disorders.
