electromyographic examination and nerve conduction studies are often the most accurate means to localize and determine the exact nature and site of the plexopathy.
Plexopathies are a form of peripheral neuropathy (i.e., a form of damage to peripheral nerves).
Depending on the source of the damage, treatment for plexopathies can include direct surgical correction, medication to relieve pain, and/or physical therapy.
Diagnosis of multifocal motor neuropathy usually requires both a careful physical examination, as well as electromyographic (EMG) testing.
Common plexopathies include brachial plexopathy affecting the upper thorax, arm, and shoulder region, cervical plexopathy affecting the neck and head, and lumbosacral plexopathy affecting the lower back and legs
Accurate diagnosis of congenital myasthenia requires specialized testing. These include testing specific nerves to determine if the nerves fatigue more quickly than is normal
Myotonic dystrophy is diagnosed clinically in individuals that have a specific type of muscle weakness. This is confirmed with molecular genetics testing, where the DMPK is analyzed
Blood tests, neuroimaging studies, genetic tests, electroencephalography (EEG) and other types of studies may be performed in order to determine the underlying disorder.
Tests that can be performed in the doctor's office include taking a blood pressure reading, recording the heartbeat (an electroencephalogram, or EEG), and obtaining blood for laboratory analysis
Periventricular leukomalacia can be diagnosed through cranial ultrasound, which allows the brain to be examined using ultrasound techniques through the soft spots, or fontanelles, in the baby's skull
specialized testing can be done to determine if the virus is wild type (that is, it has been acquired from the environment), or whether it is a vaccine type (polio vaccines utilize intact, but weakened viruses).
The child is often placed by an open window so he/she may be checked in natural light. Blood samples may be taken to determine the bilirubin level in the blood.
