Take the Test
Patients with symptoms of essential tremor may have great difficulty completing an exercise in which a line is drawn through a spiral pattern. Try the exercise here:
Starting at the center dot, use your mouse to click and draw your way out of the spiral without touching the sides.
Before & After
At left, results of a line exercise by a trial participant with essential tremor before the focused ultrasound procedure. At right, results from another participant who completed the exercise after receiving focused ultrasound.
