McLaren Greater Lansing’s annual electromyography volume likely ranks among top 10% in U.S.
Look no further than McLaren Greater Lansing Orthopedic Hospital (McLaren Orthopedic Hospital) for a state-of-the-art Neurodiagnostics Center that diagnoses nerve and muscle disorders. Physicians can refer children and adults to the Center for evaluation of pain, weakness, numbness, movement disorders, or musculoskeletal deficiencies. Test results are always sent back to the referring physician.
Three types of studies are offered:
ELECTROMYOGRAPHY (EMG) and NERVE CONDUCTION STUDIES
Nerve Conduction Studies
The study is used to diagnose common conditions, such as carpal tunnel syndrome, ulnar neuropathy, and peripheral neuropathy.
Small electrical impulses are used to evaluate nerve integrity. Nerves in the arm and leg have both sensory and motor function. The study evaluates whether conduction pathways are transmitting information appropriately.
Very specialized studies may be used to evaluate diseases, such as Myasthenia Gravis, which affect the junction where nerves connect with muscle fibers.
This is a needle examination of selected muscles of the arms, legs and small muscles along the spinal regions of the neck and back. This test is primarily used to evaluate cervical or lumbar (neck or back) nerve root compression.
The needle is inserted just under the skin into the underlying muscle. Specific waveforms, indicating the presence or absence of nerve injury and its effect on muscle function, are observed on a computer screen.
The needle examination is used for diagnosis of ALS and other motor neuron disorders (polio, for example).
For patients with specific pain concerns, referring doctors may prescribe pre-test pain or anti-anxiety medication.
The test is usually well tolerated by patients, who are advised about each step of the procedure.
While preliminary results are reviewed with patients, Patients are encouraged to schedule a follow-up appointment with their referring physician for treatment recommendations.
These studies evaluate brain wave and electrical function.
Physicians refer patients for evaluation of seizures, epilepsy, attention deficit disorders, headaches, dizziness, fainting, and memory disorders.
Electrodes are taped to the scalp, and the patient is evaluated in a relaxed state. Brain wave activity is monitored and measured. Some studies are done, with electrodes in place, over a 24-hour period. All studies are reviewed by the Center’s neurologists, and results are sent to the referring physician.
EVOKED POTENTIALS (EP)
This test evaluates how long it takes for a stimulus to reach the brain from a point of stimulation.
Stimulation points may be on the arms and legs. Visual and auditory impulses are also used.
Specialized EP tests evaluate Multiple Sclerosis and other conditions affecting brain or spinal cord function.
This is done by surgeon request. Intraoperative monitoring during surgery evaluates peripheral and central nervous system function at the surgical site. This is particularly useful in back and spinal cord surgery.
The key to success in treating neurological disorders and diseases is accurate diagnosis of the problem. McLaren Orthopedic Hospital offers a sophisticated diagnostic resource for all of mid-Michigan.
Skilled technologists and physicians perform diagnostic testing in a professional, caring environment. The department boasts the only two Registered Electroneurodiagnostic Technologists (REEGT) in the mid-Michigan area!
Post-graduate fellows, residents, and medical students participate in case studies and patient care with the physicians and technologists. McLaren Orthopedic Hospital Neurodiagnostic Services and its patients benefit greatly from the academic endeavors, questions, challenges, and research initiated by the teaching staff and students.
