Our awareness of the environment and our responses to adapt to the environment can be through bioelectrical processes.
Physics (light, heat, burning, stinging, pain, contact, pressure, etc.) and chemical factors (compounds that create taste and smell) in the environment, and factors indicating the state of the organism (position, stress, gravity, starvation, etc.) through special receptors It is transformed into electrical signals and transferred to the relevant sensory nerves. These sensory nerves transmit the electrical signal it receives to the central nervous system through the spinal cord, the signals are evaluated there, compared with those in memory and perceived as sensation.
These sensations perceived in the organism determine the state of the organism against the environment and reactions occur in the organism in order to adapt to the condition of the environment.
The most well-known reaction is movement. The electrical signals coming from the generator cells responsible for the movement in the brain are transmitted to the spinal cord and the related muscles through the nerve wires originating from it.
We can compare the senses that transmit these sense and motion signals to the telephone wires, where thousands of insulated conductor wires come together.
Curl movement of our finger as we want; Although it will be explained in computer language, it can be accomplished by making healthy exchange of millions of bits per second. In order to achieve this, the electrical signal passing through the nerve wires must have a certain speed and quality, the electrical signal flow from the nerves to the muscles and the muscles must have a certain standard in their own electrical behavior.
Here is the laboratory of neurology, which is used to investigate the electrical conduction in the electronurophysiology, sensory and motor transmission paths, the reflex responses in these pathways, the electrical signals from the motor nerves to the muscles, and the electrical behavior in the muscles, to determine and evaluate the electrical conditions in these elements, and to determine the abnormal findings and to determine what the pathology is. and EMG reviews are one of these methods.
What to do in EMG reviews?
- Measuring nerve conduction veins, motor nerves, and both, nerve conduction velocities, sensory potential and muscle action potential amplitudes.
- Measurement and temporal evaluation of reflex arc (H) and motor late responses (F), comparison with the opposite arm or leg
- Assessment of muscle rest activities, motor unit potentials and maximal contraction samples (motor neuron diseases, neck hernia, trap neuropathies, nerve injury or disruption) or the diseases of the muscles themselves by using needle electromyography method.
- Evaluation of muscular nerve junction diseases (miyastania gravis, Botulism – congestive disease – etc.) evaluating electrical exudation from nerves to muscles
- By doing this, the degree of these diseases are determined and the clinician is informed about this and assisted in evaluating treatment options.
In what cases is an EMG examination applied?
- Waist and neck hernias,
- Numbness in the hands, feet, pain and burning
- Numbness and weakness in the legs,
- Numbness in diabetes
- Numbness in dialysis patients
- Melting and progressing in the muscles
- Excessive contraction in the muscles,
- Muscle pains
- From time to time attacks of weakness
- Especially in the later hours of the day, force decreases and eyelid drops
- Facial paralysis
- Weakness in certain muscle groups
- Movement and sensory defects due to accident and piercing cutter weapon injuries
- Movement and sensory defects due to injections
- Movement and sensory defects due to poisoning and drugs
