Clinical Neurophysiological Evaluation for Simple Motor Tics

Simple motor tics are sudden, nonrhythmic jerk like movements that are often preceded by premonitory urge and can be voluntarily suppressed. Some clinical characteristic of tics such as variability of movement, distractibility and fluctuating course can mimic functional movement disorders. Here we report a case of motor tics where the physiological approach in addition to careful clinical assessments is helpful to support the diagnosis of tic.
