Neurogenic damage to the upper and lower extremities indicates damage to the nerves that innervate the upper and lower extremities, resulting in dysfunction of the limbs.
Neurogenic impairment is the term used for neurophysiologic tests such as electromyography and nerve conduction velocity, which can help to determine whether the disease is nerve or muscle damage.
Common diseases that cause neurogenic damage to the upper and lower extremities include motor neuron disease, spinal cord cavernous disease, radiculopathy due to cervical spondylosis, acute inflammatory demyelinating disease, and diabetic peripheral neuropathy. And common myogenic damage are polymyositis, acute type of muscular dystrophy and so on.
If the electromyography suggests that the upper and lower limbs have neurogenic damage, then myogenic diseases can be excluded, and which kind of neurogenic damage should be analyzed together with the patient’s clinical symptoms, physical examination, and the results of the relevant examinations, such as magnetic resonance imaging (MRI).
When neurogenic damage of upper and lower extremities occurs, it is necessary to actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
