The patient has mild postural and action tremor consistent with essential tremor. She also demonstrates distractibility when performing finger taps and suggestibility with a tuning fork, with reduction in tremor amplitude. She draws spirals slowly, with pauses, and portions of the spiral are irregular, without a consistent oscillatory pattern.
