Physical Healthcare of Jacksonville utilizes advanced computerized diagnostics for testing including Nerve Conduction Velocity (NCV) and Electromyograms (EMG) to diagnose nerve related issues. Patients preparing to take an NCV or EMG may be asked to avoid caffeine and smoking for two to three hours prior to testing. Patients may also be asked to avoid aspirin and nonsteroidal anti-inflammatory (NSAID) drugs for 24 hours before the test. Our medical team utilizes 4D color Ultrasound to properly visualize soft tissue treatment and diagnostics.
Dr. Pierce developed and utilizes a computerized, digital X-ray analysis system to properly visualize and identify skeletal abnormalities and spinal misalignment.
For the NCV test, a technician tapes two sets of electrode pads on the skin over the concerned area. The first set of electrodes sends small pulses of electricity (similar to the sensation of static electricity) to stimulate the nerve that directs a particular muscle. The second set of electrodes transmits the responding electrical signal to a recording machine. Once completed, the physician reviews the response to verify any nerve damage or muscle disease.
For the EMG test, wire electrodes are inserted into a muscle to monitor changes in the electrical voltage when the muscle is at rest and during contraction. The electrodes are attached through a series of wires to a recording instrument. Once inserted, patients are asked to contract the target muscle. The activation of the muscle fibers creates wavelengths, which are sent to the recording machine. Tests can last an hour and may take longer, depending upon the number of muscles and nerves being tested. Due to the insertion of the electrodes, patients may experience some discomfort, similar to receiving a shot.
