Nerve Conduction Study in Sharjah

What is a nerve conduction study and EMG?

The two tests are usually booked together because they answer linked questions. A nerve conduction study checks the wiring: small sticky pads are placed on the skin over a nerve, a brief electrical pulse is given a little further along it, and the equipment times how long the signal takes to arrive and measures how big it is when it gets there. A slowed signal suggests the insulating coating of the nerve is affected, while a small signal suggests the nerve fibres themselves are damaged. That distinction helps narrow down the cause.

Electromyography, or EMG, checks the muscles those nerves supply. A needle about as fine as an acupuncture needle is placed into a muscle and records its electrical activity at rest and as you tighten it. Healthy muscle is electrically quiet at rest, so activity at rest tells the neurologist something useful. At Dar Al Kamal Hospital, Sharjah, the nerve conduction study in Sharjah is performed and interpreted by the neurologist, who links the findings to your symptoms and examination.

Who needs it

Your neurologist may recommend these tests if you have:

• Numbness, tingling or pins and needles in the hands, particularly at night
• Burning or numb feet, which may point to peripheral neuropathy
• Pain, numbness or weakness spreading down an arm or leg from the neck or back, suggesting a trapped nerve root
• Weakness, wasting or cramping of muscles with an unclear cause
• A dropped foot or a weak hand after an injury, or after pressure on a nerve from sitting or lying in one position

Carpal tunnel syndrome, where the median nerve is squeezed at the wrist, is among the most common reasons for referral. The test shows how badly the nerve is affected, which guides the choice between a wrist splint, an injection and surgery. People with diabetes are tested often, because nerve damage is a frequent complication of the condition and diabetes is common in the UAE. When the pattern suggests a problem in the spine, imaging through radiology, such as an MRI scan, is often arranged alongside the test.

What happens

1. You lie on a couch in a quiet room, wearing loose clothing or a gown so the arms and legs are easy to reach.
2. The skin is cleaned and small pads are stuck over the muscles and nerves being studied. Cold hands or feet are warmed first, because cool skin slows the signal and can make a healthy nerve look damaged.
3. Brief electrical pulses are given over each nerve in turn. Each one feels like a quick tap or snap, sometimes with a small twitch of the finger or toe.
4. For the EMG, the neurologist places the fine needle into a few selected muscles. You relax, then gently tighten the muscle when asked. The activity is shown on the screen and played as a crackling sound through a speaker.
5. The neurologist chooses the next nerve or muscle based on what each result shows, so the exact route of the test is tailored to you.

Most people describe the sensations as odd and mildly uncomfortable. Tell the neurologist if you would like a pause at any point.

Preparing for it

Clean, warm, bare skin gives the clearest recording.

• Bathe or shower on the day and leave the skin free of creams, lotions and body oils, which stop the pads sticking well
• Wear loose sleeves and trousers that roll up easily, and leave rings and bracelets at home
• Take your usual medicines at the usual times
• Tell the team in advance if you take blood thinners, because the neurologist may adjust which muscles are tested with the needle
• Tell the team if you have a pacemaker or implanted defibrillator, so the pulses can be planned safely
• Bring a list of your medicines, recent blood test results and any previous nerve test reports

Air-conditioned waiting rooms in Sharjah can leave the hands and feet cool, so wear socks and bring a light layer. During Ramadan, discuss appointment timing and medicine times with your neurologist in advance.

Afterwards

You can drive, work and carry on with your normal day straight away. A needled muscle may feel a little sore or show a small bruise for a short while, and a simple painkiller usually helps. The neurologist often explains the main findings at the end of the test and discusses the full picture, including treatment and any further tests, at your follow-up appointment.

Contact the neurology team if a needle site becomes very swollen, hot or increasingly painful. Call emergency services immediately if you develop sudden weakness of the face, arm or leg, or difficulty speaking, whatever your test result.

Cost and insurance

A nerve conduction study and EMG requested by a doctor for symptoms is covered by most UAE health insurance plans, and some insurers require pre-approval before the appointment. Dar Al Kamal Hospital, Sharjah can help you confirm your cover on 06 599 7777.
