Orlando Avendaño has lived with Essential Tremor in one of his hands for 30 years, affecting every aspect of his life. But a focused ultrasound treatment on his brain, which lasted just a few hours, has restored the freedom that these tremors had taken from him. Avendaño, 72, said the movement disorder caused his hand to tremble uncontrollably whenever he performs fine motor tasks. "We’ve avoided visiting people because he feels embarrassed.”But his situation was about to change, thanks to an Israeli-developed technology that uses ultrasound inside an MRI machine. You can't.”Just as he arrived that morning, Avendaño went home a few hours later—without a tremor in his hand.
