The Neurophysiology Unit in Vigo
The Neurophysiology service at the Ribera Povisa Hospital in Vigo is dedicated to functional diagnosis of the nervous system through tests that evaluate brain, nerve and muscle electrical activity. We offer advanced examinations, therapeutic monitoring and guidance in neurological pathologies, to provide the patient with a comprehensive approach tailored to their needs.
Meet our team of clinical neurophysiologists in Vigo
Our team consists of specialists in clinical neurophysiology, with extensive experience in neurological diagnostic tests, and the management of pathologies such as epilepsy, neuropathies, sleep disorders, etc. Each patient receives close, professional and quality care from the first consultation.

What should you know?
What is neurophysiology? Functional diagnosis of the nervous system
Clinical neurophysiology is the specialty that studies the electrical function of the brain, nerves, and muscles. Through tests such as EEG, EMG, evoked potentials, and sleep studies, we analyze how your nervous system functions both at rest and under stimulation, allowing us to detect, monitor, and guide treatments for various neurological diseases.
Exploration, monitoring and therapeutic guidance for neurological pathologies
We offer comprehensive follow-up for neurological conditions requiring functional diagnosis: from the initial assessment to the design of medical or physiotherapy treatment plans (in collaboration with Neurology). We provide ongoing support in symptom management and adjusting the appropriate treatment.
Key neurophysiological tests: electroencephalogram, electromyography, electroneurology, evoked potentials, sleep studies...
• Electroencephalogram (EEG): It records brain electrical activity, both during wakefulness and sleep, to diagnose epilepsy, sleep disorders, or other neurological conditions.
• Simultaneous video-electrocephalography: Synchronized recording of EEG and patient video to correlate electrical activity with clinical manifestations; useful in epilepsy and in differentiating seizures from non-epileptic events.
• Electroneurology (ENG): Study of the conduction of peripheral nerves by means of electrical stimuli, measuring latencies, amplitudes and speed; useful for diagnosing neuropathies and entrapments (e.g. carpal tunnel).
• Electromyography (EMG): It measures the function of muscles and motor nerves, useful in neuropathies, myopathies, carpal tunnel syndrome, etc.
• Single-fiber electromyography: It evaluates neuromuscular transmission (jitter) to diagnose myasthenia gravis and other neuromuscular junction disorders.
• Evoked potentials: They evaluate nerve conduction in response to somatosensory, visual, and auditory stimuli.
• Eelectroretinogram: It records the electrical response of the retina to light stimuli to evaluate photoreceptors and retinal pathways.
• Electroculogram: It measures the corneoretinal potential during eye movements to assess the pigment epithelium and retinal function.
• Sleep studies: They help diagnose sleep disorders such as apnea, narcolepsy, or parasomnias. (PSG: polysomnography; LMT: multiple sleep latency test)
Who is the consultation for? We explore brain, nerve, and muscle activity using the latest technology.
This consultation is indicated for patients of all ages who present with symptoms such as seizures, sleep disturbances, muscle weakness, tingling, numbness, nerve pain, movement disorders, or sensory deficits. It is also for follow-up of previously diagnosed conditions or after referral by Neurology; and for those who need a functional assessment to plan treatment.
Specialized treatments and diagnostic tests
Our clinical neurophysiology team in Vigo performs advanced diagnostic tests for the study and monitoring of various neurological and muscular pathologies, among others:
Amyotrophic lateral sclerosis (ALS)
Electromyography allows us to assess the function of motor neurons and detect their deterioration.
Attention deficit hyperactivity disorder (ADHD)
EEG helps to identify brain electrical patterns characteristic of this disorder.
Parkinson's disease
Motor impairments and response to treatment are evaluated using evoked potentials and EMG.
Narcolepsy
Sleep studies allow for the diagnosis of excessive sleepiness and sudden sleep episodes.
Epilepsy
EEG is the key test for recording epileptic seizures and abnormal brain activity.
Myasthenia gravis
Repetitive stimulation and EMG detect failures in neuromuscular transmission.
Carpal tunnel syndrome
Nerve conduction studies confirm entrapment of the median nerve at the wrist.
Dementia
EEG and evoked potentials help to differentiate types of cognitive impairment.
Restless Leg Syndrome
Polysomnography detects alterations in nighttime rest related to this disorder.
Myopathies
EMG distinguishes between muscular and neurological diseases.
Polyneuropathies
Nerve conduction studies diagnose the involvement of multiple peripheral nerves.
Parasomnias
Sleep studies allow the identification of abnormal behaviors during rest.
