Our neurophysiology department diagnoses and monitors disorders of the brain and nervous system.

Coming into hospital

Neurophysiology 4

The clinical neurophysiology department at Worcestershire Royal Hospital conducts around 5000 investigations each year.

We offer a wide range of neurophysiological procedures for both adults and children. We often train student clinical physiologists. A student may watch or perform your test under supervision. 

Unfortunately, we cannot see people who are more than 20 minutes late. It can take a long time to park, so give yourself plenty of time to get here.

What to bring to hospital

A list of your or your child's current medication.

Some of our procedures may leave your hair 'messy' and needing to be washed when you get home. You might like to bring a hat or head scarf.

If you are attending a prolonged or multiple sleep test, bring something to keep you occupied.

Bring any drinks or bottle feeds your child may need as well as any comforting items, such as a dummy, toy or blanket.

If your child is coming in for Melatonin sleep electroencephalogram (EEG) their Melatonin is usually sent to us. However if your doctor has given you the prescription, please take this to your pharmacist as soon as possible so you can bring the Melatonin to your child's appointment.

If you are attending a visual evoked potential electroretinography (VEP/ERG) appointment, please bring your glasses or spectacles with you.

How long will it take?

Each procedure takes a different amount of time to complete.

  • Visual evoked potential electroretinography (VEP/ERG) will take 1 - 2 hours
  • Routine electroencephalograms (EEGs) take up to 1 hour
  • Prolonged electroencephalograms (EEGs) may take 2 - 6 hours
  • Electroencephalograms (EEGs) with partial or full sleep deprivation take up to 2 hours
  • Multiple sleep latency tests (MSLT) will take most of the day (lunch is provided)
  • Nerve conduction studies (NCS) and electromyograms (EMG) take around 20 minutes

Preparing for your sleep test

Please eat and drink and take your medications as normal leading up to your sleep test. It is best to make sure you eat something a few hours before your appointment.

Your hair should be clean and free of hair styling products on the day of the test.

Full sleep deprivation (EEG)

We would like you to sleep during the EEG test.

Remain awake all night before the morning of your EEG. You will be sleepy before and after your EEG. You should not drive to or from this appointment and it is best to have someone accompany you home.

If you fall asleep during the night before your test, please call us to make another appointment.

Partial sleep deprivation (EEG)

Go to bed late the night before and get up very early on the day of your test.

Aim to have 2 - 4 hours sleep the night before.

Multiple sleep latency test (MSLT)

If you are taking any medication, in particular benzodiazepines, anti-depressants or sleeping tablets, please call us beforehand to let us know, as some medications can affect the recording.

Preparing your child for a sleep test

Your child can eat and drink and take their medications as normal leading up to their sleep test. It is best to make sure they eat something a few hours before their appointment.

Their hair should be clean and free of hair styling products on the day of the test.

Children 3 years and under

Please make sure that you bring your child as tired as possible.

Avoid any daytime naps your child may normally have.

We understand that this may be difficult but it is very important for this type of test.

Children over 3 years

You should aim for them to have 2 - 4 hours sleep on the night before the test, they should go to bed late and get up very early on the morning of the test.

Ideally they will then fall asleep during the EEG test.

During your sleep test

Electroencephalograms (EEG)

Small silver discs will be stuck onto your head with a paste.

You can either sit on a reclining chair or lie on a bed and relax.

You will not feel anything from an EEG.

During the EEG, we may ask you to do some deep breathing and look at a flickering light. You should be aware that flickering lights and /or deep breathing may increase the risk that you may have one of their attacks/ seizures.

Multiple sleep latency test (MSLT)

This test will be in several parts and will take most of the day.

We will take four or five recordings over the course of the day. Each recording will take up to an hour. You will not feel anything during the recording.

After each recording you will be asked to leave the department and return about one hour later for the next recording.

During this procedure you should not consume alcohol or caffeine or sleepinbetween recordings.

Preparing for your nerve conduction study

Wear loose clothing so that your arms and legs are easily accessible.

If the tests are on the nerves in your hands or arms, wear a short sleeved blouse or t-shirt with a jumper on top if it is cold.

If the test is on the nerves in your feet or legs, wear loose trousers and socks (not tights).

Wear gloves or woolly socks to keep your hands and feet warm.

If the tests are on your hands, please take off all jewellery and watches before the test. You can leave your wedding ring on.

Your hands, arms, legs and feet need to be clean and free of all moisturising creams or lotions, including tanning creams.

During your nerve conduction study

Small pads are placed on to the hands or feet and the nerve is stimulated.

You will feel a tapping or twitching sensation.

There are no after effects from these tests.

Occasionally additional tests are needed and the consultant will explain these if required.

Your test will take about 20 minutes, but is tailored to suit your particular symptoms, so may take less or more time.
