About Nihon Kohden company:
When Dr. Yoshiro Ogino was studying medicine and doing research in electrical engineering, one day he was working on an experiment involving the stimulation of the neuromuscular tissue of a small bird. That’s when he understood and realized the important parameters of biology and noted: “to measure the parameters of a living body, it requires several hundred times more sensitivity and at least two decimal places more than the equipment developed in Japan by leading experts in electrical engineering.”
He wondered if it was possible to apply a higher level of engineering to the subtleties of biology and thus study the parameters of the human body. With this strong inspiration, he studied medicine and founded Nihon Kohden Corp. in August 1951. With the unwavering belief that “to cure disease is something that transcends politics and national borders, and we will never regret putting all our energy into this cause”, Nihon Kohden has produced a range of cutting-edge medical electronic devices.
As medicine developed, Nihon Kohden products branched out into many fields. However, the original vision has not changed and continues to inspire Nihon Kohden engineers. Thanks to the late Dr. Yoshio Ogino, the founder of Nihon Kohden, the company still offers top medical devices with the most advanced medical engineering solutions and continues to grow as a company that provides the world with advanced technology based on over 60 years of experience in medical engineering.
EMNG (electromyoneurography) is an indispensable diagnostic method for diseases of muscles and peripheral nerves, which examines the electrical potential of muscles and the electrical conductivity of nerves with the help of surface or needle electrodes. It is an irreplaceable method in the diagnosis of pathology of muscles, peripheral nerves and nerve roots from the spine. With this method, it is possible to precisely determine which nerve root in the spine is damaged, in what degree and percentage, and whether the nerve compression is acute or chronic. The EMNG search is performed by Dr. Ante Katić, a specialist in physical medicine and rehabilitation.
EMNG examination is performed for diagnosis:
- peripheral neuropathies,
- various types of polyneuropathies (eg diabetic),
- lumboischialgia,
- herniation of intervertebral discs
- nerve injury (nerve paralysis, traffic accidents and injuries to the spine and extremities, postoperative conditions),
- primary neuromuscular diseases,
- hereditary neuropathies,
- compression of nerves: in so-called canalicular syndromes – e.g. nerve entrapment in the elbow, carpal canal (hand), Gyon’s canal (hand), peroneal canal (knee), tarsal canal (ankle),
- some rheumatological diseases,
- chronic diseases,
- spinal amyotrophy,
- ALS – amyotrophic lateral sclerosis,
- polio.
In the Aqua Med polyclinic, a new generation Nihon Kohden device is used, the method is less invasive, almost painless, because most of the recording is done with digital electrodes, and a smaller part of the recording with needles. The search lasts from 30 to 60 minutes. There is no contraindication for this test.
At the Aqua Med polyclinic, EMNG (electromyoneurography) can be performed, namely:
– EMNG of the upper extremities i
– EMNG of the lower extremities.
EMNG is determined individually, in accordance with the referral diagnosis and the duration of the complaints. It is performed strictly according to the principle of minimizing pain and discomfort for patients.
EMNG (electromyoneurography) is a diagnostic procedure that evaluates the function of the peripheral nervous system, and includes the activities of the muscles and nerves that control them.
It consists of two parts: electroneurography (ENG) and electromyography (EMG).
• ENG (electroneurography) is a test that analyzes the function of peripheral nerves. The obtained results indicate the height of the site and the type of peripheral nerve damage. The search is performed with surface electrodes that are placed on the skin above the examined muscle. During the examination, there are no stings or other unpleasant sensations, i.e. the examination is completely painless.
• EMG (electromyography) shows the state of the muscles and shows whether weakness or loss of muscle mass is the result of nerve disease or the muscle itself. The search is performed using a thin disposable sterile needle – electrode. The method is irreplaceable because it gives the right answer about the real state of the muscles. To be used only in exceptional cases, a detailed medical history and neurological status is taken before the examination. Thanks to the expertise and experience of our specialist physiatrist, Dr. Katić, who performs the examination and high-quality equipment, that feeling is reduced to a minimum.
Površinska elektromioneurografijasekoristi u svim slučajevima gdje potvrda radne dijagnoze ne requires data only available using a needle electrode. It is most often used to examine symptoms such as pain, tingling, numbness, or muscle weakness. The test lasts 30-60 minutes. Peripheral nerve conduction testing is performed on motor and sensory nerves using surface electrodes. The test involves the use of a series of mild electrical stimuli applied to specific areas on the arms or legs. Although the examination is usually not painful, the patient may experience a slight local burning sensation during the examination.
The course of the search and preparation for the search:
Be sure to bring all medical documentation (medical history) related to the examination you are doing. Tell the doctor performing the EMNG if you have a pacemaker or any other electrical medical device implanted, if you use blood thinners, if you have hemophilia or a clotting disorder. Before the examination, take a shower to remove oil from the skin. Do not apply lotions or creams before the test so that the electrodes stick better to the skin. If additional instructions are required, you will receive them when ordering.
During the test, patients were asked to contract and relax certain muscles. Patients should know that they are partially undressed before the examination itself, this means that the extremities (limbs) being examined must be accessible for examination. The examination does not require special preparations. Food can be consumed normally before the examination.
What can you expect during EMNG?
The test is performed on computerized devices, where the conductivity of peripheral nerves is tested with the help of surface electrodes placed on the skin, while sterile, disposable thin needle-electrodes are used to test muscle function.
The electrodes will sometimes release a small electrical pulse that can be felt as a jolt or spasm. Doctors will assess whether there is any spontaneous electrical activity when the muscle is at rest and the degree of activity when the muscle is stressed, i.e. contracted. An EMNG examination usually lasts from 30 to 60 minutes, depending on the area of examination.
EMNG – results immediately available
Test results are available immediately upon completion of the search. The search gives us valuable information about the condition of your muscles and nerves, which helps your doctor to diagnose and determine the appropriate treatment for your disease or condition. The search leaves no lasting consequences.
What after EMNG?
There may be temporary, minor bruising where the electrode was placed. Bruising should fade within a few days. If the bruise persists, contact your primary care physician.
The price of an examination in our polyclinic for:
• EMNG of hands or feet amounts to EUR 65 / 489,74 kn.
• EMNG of hands and feet amounts to EUR 105 / 791,12 kn.
