A population-based analysis of physician utilization of nerve conduction studies (NCS) for the assessment of DPN was conducted. All electrodiagnostic encounters over a 30-month period using a computer-based neurodiagnostic instrument linked to a data registry were analyzed retrospectively. The DPN case definition was abnormal sural and peroneal nerve conduction. The study cohort consisted of a total of 63,779 electrodiagnostic encounters performed by 3468 physician practices. Primary care and internal medicine physicians represented 80.1% of the practices and accounted for 65.7% of the encounters. Endocrinologists represented 4.6% of the practices and 20.1% of the encounters. The demographics of patients were 52.7% female; 63.411.8 (meanstandard deviation) years (age); 168.110.9cm (height); 92.222.6 kg (weight); and 32.67.2 kg/m2 (body mass index). The most common peroneal abnormality was F-wave latency (33.6%). The sural nerve response latency and amplitude parameters had similar abnormality rates (58.3 and 62.7%). DPN w Continue reading >>

Study Of Nerve Conduction Velocity In Type II Diabetes Mellitus NJIRM 2015; Vol. 6(4) July August eISSN: 0975-9840 pISSN: 2230 - 9969 Study Of Nerve Conduction Velocity In Type II Diabetes Mellitus Nidhi Yadav, Anjali Shete, Prashant Yadav, Nisha Yadav, S.T.Khan Department of Physiology, Government Medical College, Aurangabad. Maharashtra, India Abstract: Background& Objectives: Diabetic neuropathy is the most common and troublesome complication of diabetes mellitus, leading to great morbidity and resulting in burden for diabetes care. The progression of neuropathy can be reduced by early detection and intervention. Nerve conduction studies are the most sensitive indices of the severity of neuropathy. These tests can be used to localize lesions and describe the type and severity of the pathophysiologic process, including alterations that are not recognized clinically. This study was undertaken to compare nerve conduction study results in diabetes mellitus patients with good glycemic control and poor glycemic control and to compare it with non-diabetic subjects. This study aims to signify the role of nerve conduction study in diabetes mellitus. This can help in identifying the asymptomatic stage of diabetic neuropathy so that suitable preventive measures can be taken. Methodology: Total 90 subjects were included in the study group. 30 were non diabetic subjects and 60 were known cases of Type II diabetes mellitus patients attending diabetic OPD at GMCH, Aurangabad of age 30-50 years with duration of 5- 10 years. Glycated haemoglobin levels were estimated and on this basis the cases were divided into two groups; diabetic patients with good glycemic control and diabetic patients with poor glycemic control. Nerve Conduction parameters were measured by computerized micromed Continue reading >>

All electrophysiological studies were performed on a multiple channel EMG apparatus (Medelec Sapphire 4ME). The electrodiagnosis protocol recommended by the American Diabetes Association was used for the NCS12. Median, ulnar and peroneal motor fibers, median and ulnar sensory fibers and sural nerves were studied. The compound muscle action potentials (CMAP) were recorded with surface recording bar electrodes, which were placed over the main bulk of abductor pollicis brevis, abductor digiti minimi and extensor digitorum brevis for the median, ulnar and peroneal nerves respectively. A bipolar percutaneous stimulator was located at the wrist 7 cm proximal to the active recording electrode for median and ulnar motor NCS. Proximally the median nerve was stimulated just medial to the biceps tendon at the elbow crease and the ulnar nerve was stimulated below and above the elbow with a distance of at least 14 cm. The stimulation was delivered between the tendons of tibialis anterior and extansor hallicus longus muscles 9 cm proximal to the active recording electrode and from the fibular head for the peroneal motor NCS. A supramaximal stimulation of 0.1 ms duration was delivered for all the motor NCS. The sensory nerve action potentials (SNAP) were recorded by antidromic tecniques. The recording electrode was placed on the 3rd and the 5th digit for median and ulnar nerves respectively with stimulating 13 cm proximally from the wrist just medial to the flexor carpi radialis tendon for the median nerve and 11 cm proximally just posterior to the flexor carpi ulnaris tendon for the ulnar nerve. The recording electrode for sural nerve studies was placed behind the lateral malleolus and it was stimulated in the midcalf 14 cm proximal to the active recording electrode. All SNAP's were Continue reading >>

Electromyography (emg) And Nerve Conduction Studies (ncs) For Neuropathy Diagnosis

Electromyography (emg) And Nerve Conduction Studies (ncs) For Neuropathy Diagnosis

Electromyography (EMG) and nerve conduction studies (NCS) for Neuropathy Diagnosis This test has two parts. Nerve conduction studies are used to measure the health of your nerves. Electric shocks are administered by the nerve conduction technician to skin directly overlying the nerve. The response is measured by a second set of electrodes applied to the surface of skin. The strength of these shocks is equivalent to a strong static-electricity shock. During the EMG, the doctor will insert a very thin needle into one muscle at a time. You will be asked to relax the muscle and then contract the muscle after the needle is inserted. The needle is connected to a computer that helps the doctor determine whether your muscle is healthy or affected by a disease of the muscle or nerve. The number of muscles to be tested is highly variable and depends upon your symptoms and what is found during the actual test. Please do not apply lotion to your skin on the day of your appointment as this may interfere with nerve conduction testing. Also, let your EMG doctor know if you are taking blood thinners prior to the exam. Continue reading >>

Diabetic Neuropathy: Your Diagnosis

Diabetic Neuropathy: Your Diagnosis

If you've been diagnosed with prediabetes or type 1 or type 2 diabetes, getting checked for diabetic peripheral neuropathy—damage to nerves in your feet, lower legs, hands and elsewhere—is critical. Having this common condition diagnosed can help you get relief from nerve pain, protect your feet from small injuries before they become more serious, help you walk more easily if nerve damage is affecting your balance or coordination, and may motivate you to keep your glucose (blood sugar) within healthy limits and follow a healthy lifestyle strategies. This could prevent or delay the development of neuropathy if you have type 1 diabetes and may prevent or slow down the worsening of neuropathy if you have type 2 diabetes. That’s why the American Diabetes Association, the American Association of Clinical Endocrinologists1 and the American College of Endocrinology recommend screening for PDN when you are first diagnosed with type 2 diabetes or five years after a diagnosis of type 1 diabetes. After that, get rescreened every year. See your doctor sooner if you develop symptoms, such as pain, tingling or numbness in your feet between screenings. If you have prediabetes, ask your doctor about a PDN screening if you have symptoms, the ADA now recommends. 2 How Peripheral Neuropathy is Diagnosed Your screening may begin with a physical exam to assess your overall health – including your blood pressure, heart rate, reflexes, muscle strength, and ability to move. Your healthcare provider will ask you questions about your health and your symptoms; he or she will also run a few tests. In addition, your doctor will rule out other causes of nerve damage such as thyroid problems, vitamin B12 deficiency, infections like Lyme disease or hepatitis B, some medications and more. 3 A k Continue reading >>

Amplitude Of Sensory Nerve Action Potential In Early Stage Diabetic Peripheral Neuropathy: An Analysis Of 500 Cases Zhang Y, Li J, Wang T, Wang J - Neural Regen Res

Early diagnosis of diabetic peripheral neuropathy is important for the successful treatment of diabetes mellitus. In the present study, we recruited 500 diabetic patients from the Fourth Affiliated Hospital of Kunming Medical University in China from June 2008 to September 2013: 221 cases showed symptoms of peripheral neuropathy (symptomatic group) and 279 cases had no symptoms of peripheral impairment (asymptomatic group). One hundred healthy control subjects were also recruited. Nerve conduction studies revealed that distal motor latency was longer, sensory nerve conduction velocity was slower, and sensory nerve action potential and amplitude of compound muscle action potential were significantly lower in the median, ulnar, posterior tibial and common peroneal nerve in the diabetic groups compared with control subjects. Moreover, the alterations were more obvious in patients with symptoms of peripheral neuropathy. Of the 500 diabetic patients, neural conduction abnormalities were detected in 358 cases (71.6%), among which impairment of the common peroneal nerve was most prominent. Sensory nerve abnormality was more obvious than motor nerve abnormality in the diabetic groups. The amplitude of sensory nerve action potential was the most sensitive measure of peripheral neuropathy. Our results reveal that varying degrees of nerve conduction changes are present in the early, asymptomatic stage of diabetic peripheral neuropathy.

Diabetic Neuropathy--a Review

Diabetic Neuropathy--a Review

Nat Clin Pract Neurol.2007;3(6):331-340. Diagnosis of Diabetic Neuropathy: Nerve Conduction Studies In symptomatic diabetic neuropathy, there is slowing of nerve conduction velocity owing to demyelination and loss of large myelinated fibers, and a decrease in nerve action potentials owing to loss of axons.[ 39 , 56 , 57 ] Purely demyelinative neuropathy is rare in patients with diabetes, and is more suggestive of a demyelinative neuropathy of inflammatory or dysglobulinemic origin.[ 58 ] Systematic electrophysiological testing is not necessary in diabetic patients with typical peripheral neuropathy. Changes in conduction velocity can be detected in asymptomatic patients, but their presence is not predictive of the onset of symptomatic neuropathy. Nerve conduction studies (NCS) are the most objective noninvasive measures of nerve function. They represent a valuable tool of evaluation of neuropathy in large clinical and epidemiological studies.[ 59 ] In clinical practice, however, NCS should not be considered a substitute for careful clinical examination, because NCS have many pitfalls and their results must be interpreted in the context of clinical data. In the case of LDDP, as in all small-fiber polyneuropathies, the main drawback of NCS is that small myelinated and unmyelinated nerve fibers, which are affected early in the disease course of diabetic neuropathy, do not contribute to the sensory action potential detected by routine NCS. The sensory action potential is altered only after involvement of larger myelinated fibers, which is often a late event in patients with diabetes. Electrophysiological data must, therefore, always be evaluated in a clinical context. Continue reading >>

Diagnosis

Diagnosis

Print Diabetic neuropathy is usually diagnosed based on your symptoms, your medical history and a physical exam. During the exam, your doctor is likely to check your muscle strength and tone, tendon reflexes, and sensitivity to touch, temperature and vibration. Your doctor may also conduct tests that include: Filament test. Sensitivity to touch may be tested using a soft nylon fiber called a monofilament. Nerve conduction studies. This test measures how quickly the nerves in your arms and legs conduct electrical signals. It's often used to diagnose carpal tunnel syndrome. Electromyography (EMG). Often performed along with nerve conduction studies, electromyography measures the electrical discharges produced in your muscles. Quantitative sensory testing. This noninvasive test is used to assess how your nerves respond to vibration and changes in temperature. Autonomic testing. If you have symptoms of autonomic neuropathy, your doctor may request special tests to look at your blood pressure in different positions and assess your ability to sweat. The American Diabetes Association recommends that all people with diabetes have a comprehensive foot exam — either by a doctor or by a foot specialist (podiatrist) — at least once a year. In addition, your feet should be checked for sores, cracked skin, calluses, blisters, and bone and joint abnormalities at every office visit. Treatment Diabetic neuropathy has no known cure. Treatment for diabetic neuropathy focuses on: Slowing progression of the disease Relieving pain Managing complications and restoring function Slowing progression of the disease Consistently keeping blood sugar within a target range can help prevent or delay the progression of diabetic neuropathy and may even improve some of the symptoms you already have.

Diabetic Neuropathy Diagnosis

Diabetic Neuropathy Diagnosis

Your physician will conduct a medical history, physical exam, and even a pin-prick test to determine if you have diabetic neuropathy. In diagnosing diabetic neuropathy—also called diabetic nerve damage—your doctor may run a few exams and tests. He or she will also ask you about your symptoms. All this is done to get an accurate diagnosis. It's important to understand what type of diabetic neuropathy you have (diabetic peripheral neuropathy, proximal neuropathy, autonomic neuropathy, or focal neuropathy), as well as the extent of nerve damage. When describing your symptoms, be as specific as you can. The different types of diabetic neuropathy affect different nerves and cause different symptoms. Describing the severity and location of your pain (or other symptoms) will also help your doctor make an accurate diagnosis. Exams and Tests to Diagnose Diabetic Neuropathy The doctor will most likely perform a physical exam to assess your general physical condition, including your blood pressure, heart rate, reflexes, muscle strength, and ability to move. A critical part of the physical exam is a comprehensive foot exam. (People with diabetes should have a yearly foot exam.) In diabetic peripheral neuropathy—the most common type of diabetic neuropathy—the nerves in the feet and legs are usually the most damaged. Therefore, it's critical to check your foot health by assessing the circulation, bones, muscles, and skin. A neurological exam is also important in diagnosing diabetic neuropathy. Using various tests, the doctor will be able to determine how well your nerves are working. As mentioned before, different nerves transmit different messages; some are in charge of temperature and others deal with touch or vibration. By testing these different types of nerves, your doct Continue reading >>

Electrodiagnostic Testing

Electrodiagnostic Testing

An electromyogram (EMG) is a test that measures the electrical activity of a muscle. It detects any signs of blocking or slowing down of responses to nerve stimulation. The test provides information about the muscle itself and shows how well it receives stimulation from the nerve. Anerve conduction velocity(NCV) test is often done at the same time as an EMG. An EMG is often used to evaluate unexplained muscle weakness, twitching or paralysis, and to find the causes of numbness, tingling and pain. EMG testing can differentiate between true weakness and reduced use because of pain or lack of motivation. It can also determine whether a muscle disorder begins in the muscle itself or is caused by a nerve disorder. In an EMG, a physician or technician inserts a very fine needle, which serves as an electrode, through the skin into the muscle. With the electrode in place, the patient is asked to slowly contract the musclefor example, by bending the armwith gradually increasing force, while the electrical activity is being recorded. The activity can be displayed visually on an oscilloscope or screen, or played audibly through a speaker. The results can provide information about the ability of the muscle to respond to nerve stimulation. The patient may feel some minor discomfort, similar to an injection, when the needle or needles are inserted. Afterward, the examined muscle may feel tender or sore for a few days, and there may be a small bruise. A nerve conduction velocity test, also called a nerve conduction study, measures how quickly electrical impulses move along a nerve. It is often done at the same time as anelectromyogram,in order to exclude or detect muscle disorders. A healthy nerve conducts signals with greater speed and strength than a damaged nerve. The speed of ner Continue reading >>

Comparison of nerve conduction studies with diabetic neuropathy symptom score and diabetic neuropathy examination score in type-2 diabetics for detection of Sensorimotor Polyneuropathy Ambreen Asad, Amina Nadeem ( Army Medical College/NUST,Rawalpindi. ) Muhammad Amjad Hameed, Umar Ali Khan ( Islamic International Medical College,Rawalpindi. ) Mujeeb-ur-Rahman Abid Butt ( Combined Military Hospital,Rawalpindi. ) Nadeem Ahmed ( Armed Forces Institute of Rehabilitation Medicine,Rawalpindi. ) Objective: To compare the nerve conduction studies in clinically undetectable and detectable sensorimotor polyneuropathy in type 2 diabetics. Methods: Diagnosed diabetics (n=60) were divided in two groups. Group 1 (n1=30) with clinically undetectable and group 2 (n2=30) with clinically detectable Diabetic Polyneuropathy. Detection of the sensorimotor neuropathy was done according to Diabetic Neuropathy Symptom Score and Diabetic Neuropathy Examination scores. The simplified nerve conduction studies protocol was followed in recording amplitudes, velocities and latencies of minimum two (Sural, Peroneal) and maximum six i.e. three sensory (Sural, Ulnar, Median) and three motor (Peroneal, Ulnar, Tibial) nerves. Results: The comparisons were done between different parameters of nerve conduction studies with the neurological scores in undetectable and detectable groups using Pearson's chi square test. The amplitudes, velocities, latencies, outcome and grading of neuropathy in nerve conduction studies when compared with neurological detection scores showed a significant relation in each group regarding evaluation (p=0.005, p=0.004, p=0.05, p=0.00001, p=0.003 respectively). Conclusions: Diabetic Neuropathy Symptom Score and Diabetic Neuropathy Examination Score together can help in prompt eva Continue reading >>

Nerve Conduction Velocity (ncv) Test: What To Expect

Nerve Conduction Velocity (ncv) Test: What To Expect

A nerve conduction velocity (NCV) test is used to assess nerve damage and dysfunction. Also known as a nerve conduction study, the procedure measures how quickly electrical signals move through your peripheral nerves. Your peripheral nerves are located outside of your brain and along your spinal cord. These nerves help you control your muscles and experience the senses. Healthy nerves send electrical signals more quickly and with greater strength than damaged nerves. The NVC test helps your doctor differentiate between an injury to the nerve fiber and an injury to the myelin sheath, the protective covering surrounding the nerve. It can also help your doctor tell the difference between a nerve disorder and a condition where a nerve injury has affected the muscles. Making these distinctions is important for proper diagnosis and determining your course of treatment. An NCV test can be used to diagnose a number of muscular and neuromuscular disorders, including: Its also important for your doctor to know if you have a pacemaker. The electrodes used in the NCV test may affect the electronic impulses of your medical device. Stop using any lotions or oils on your skin a few days before the test. These creams can prevent the electrode from being properly placed on the skin. Fasting usually isnt necessary, but you may be asked to avoid caffeine beforehand. Particulars of nerve conduction studies can vary, but they follow the same general process: Youll be asked to remove any metal objects, such as jewelry, that could interfere with the procedure. You may need to remove some clothing and wear a gown. Your doctor will find the nerve to be tested. Your doctor will place two electrodes on your skin, one that stimulates the nerve and one that records the stimulation. They may use a Continue reading >>
