St. Luke’s Movement Disorders center is a multidisciplinary center that specializes in diagnosing and treating movement disorders in adults and children, and aims to help patients and their families lead productive and normal lives with therapy and medication. Movement disorders, an important subspecialty of neurology, consists of conditions causing inadequate or excessive motor activity. Examples of movement disorders include Parkinson’s Disease, Essential Tremor, dystonia, myoclonus, ataxia, tics and chorea.
Services and Facilities:
I. Diagnosis and treatment of movement disorders
II. Neuroscan: Surface Electromyography (SEMG)
Neurophysiologic SEMG data collected by the Neuroscan can help diagnose movement disorders. Many tremor disorders are characterized by distinct muscle activity patterns. The SEMG data collected is used to classify the tremor based on its frequency, amplitude of muscle activity and its presence at rest, with posture or with activity.
Other potentially important clinical applications of SEMG include differentiating tremor from myoclonus, spasmodic torticollis from other head tremors, and primary writing tremor from writer’s cramp, as well as identifying propriospinal myoclonus and psychogenic movement disorders.
A Neuroscan examination normally takes about 1 to 1 ½ hours. It starts with a clinical assessment of the patient by the movement disorders specialist who then decides which appropriate muscles to record. Usually, surface electrodes are pasted on the skin overlying pairs of antagonistic muscle, i.e. muscles that work opposite each other like wrist flexors and extensors. Neurophysiologic data are then recorded at rest, with posture, and with action. Standard activity such as writing or drawing spirals is augmented by specific activity that a patient, by experience, knows will activate an involuntary movement.
III. Botulinum Toxin A injections
IV. Comprehensive Parkinsons Disease Profile
