When a patient presents with numbness, weakness or pain, electrodiagnostic testing can be a valuable diagnostic and prognostic tool. At Johns Hopkins, our physiatrists (rehabilitation physicians) offer a full spectrum of electrodiagnostic services. Our physicians are board-certified in electrodiagnostic medicine, and our electrodiagnostic consultations are accompanied by a detailed physical examination and functional assessment of each patient. This approach allows us to tailor the electrodiagnostic study to the specific findings on the physical examination. In this way, we can give the patient and referring physician the most accurate possible assessment of the problem. We use ultramodern, high-precision testing equipment to ensure accurate results. A preliminary report is faxed to the referring physician within 24 hours of testing, and a full report follows by mail soon thereafter. Standard services. Testing will typically include needle electromyography (EMG), nerve conduction studies (NCS) and neuromuscular junction testing (repetitive stimulation). Single-fiber EMG is also available. Special diagnostic studies. Our physicians have special expertise in the electrodiagnostic assessment of cranial nerve disorders and swallowing dysfunction. Patients with Bell's palsy, dysphagia and other craniofacial or oropharyngeal disorders will receive detailed evaluations on request. Therapy for spasticity. Hopkins physiatrists are specially trained to perform therapeutic procedures for the treatment of spasticity. Using electrodiagnostic instruments to assess the patient and to confirm results, our physicians can perform selective motor point blocks or administer botulinum toxin injections for the relief of refractory spasticity in patients with spinal cord injury, brain injury, developmental disabilities and other conditions. |
