At Neurodiagnostic Center, led by Dr. Ignacio Carrillo-Nunez, we provide Nerve Conduction Studies (NCS) to diagnose and assess nerve function and detect abnormalities affecting the peripheral nervous system. Our advanced diagnostic techniques and patient-centered approach ensure accurate diagnoses and personalized care for each patient.
A Nerve Conduction Study (NCS) is a diagnostic test that measures how well and how quickly electrical signals travel through your peripheral nerves. During the test, small electrodes are placed on the skin to stimulate the nerves with a mild electrical impulse. The results help determine if there is nerve damage or dysfunction.
Persistent numbness, tingling, or burning sensations in the hands, feet, arms, or legs
Muscle weakness that affects grip strength or mobility
Sharp or radiating pain that may suggest nerve compression
Unexplained cramping or discomfort in the muscles
Difficulty with fine motor skills such as buttoning clothing or holding small objects
Ongoing pain or discomfort after an injury that hasn’t improved
Electrode Placement: Small electrodes are placed on the skin over the nerve to be tested.
Electrical Stimulation: A mild electrical impulse is applied to stimulate the nerve.
Signal Recording: The speed and strength of the nerve’s response are recorded to assess how well the nerve is functioning.
Data Interpretation: Dr. Carrillo-Nunez reviews the results to identify any signs of nerve damage or dysfunction.
Preparation: No special preparation is required. Patients may be asked to avoid lotions or oils on the skin.
Electrode Application: Small, adhesive electrodes are placed on the skin over the targeted nerve and muscle.
Mild Sensation: A brief electrical impulse is delivered to stimulate the nerve, causing a mild tingling or twitching sensation.
Duration: The procedure typically lasts 30-60 minutes, depending on the number of nerves tested.
Post-Procedure: There is no downtime, and patients can return to normal activities immediately.
Carpal Tunnel Syndrome: Compression of the median nerve causing pain, numbness, and weakness in the hand.
Peripheral Neuropathy: Nerve damage often caused by diabetes or other underlying conditions.
Radiculopathy: Nerve root compression that may cause pain, weakness, and tingling in the arms or legs.
Guillain-Barré Syndrome: A rare condition where the immune system attacks the peripheral nerves.
Sciatic Nerve Dysfunction: Pain, tingling, and weakness caused by irritation or compression of the sciatic nerve.
Herniated Disc: Compression of nerves due to displacement of spinal discs, often leading to nerve pain and weakness.
Q: Is a Nerve Conduction Study painful?
A: Most patients experience mild discomfort or a tingling sensation, but the procedure is generally well-tolerated.
Q: How long does it take to get results?
A: Results are usually available within 1-2 days after Dr. Carrillo-Nunez reviews and interprets the data.
Q: Can I eat or drink before the test?
A: Yes, there are no dietary restrictions before an NCS.
Q: Will I need someone to drive me home after the test?
A: No, since the procedure is non-invasive, you can resume normal activities immediately afterward.
Q: Can an NCS detect muscle disorders?
A: NCS evaluates nerve function, but it is often performed alongside an EMG (Electromyography) to assess muscle activity.
