"[When] it first started, it was the body, and then it went to just waist up,"Highberg said. She was diagnosed with essential tremors, a type of involuntary movement disorder that does not have a clear cause.

The tremors became concentrated inher hands. Leavingher without the abilityto play the piano and write as well as she used to.

University of Virginia Health Systemresearchers calledHighberg and asked her to participate in a trail that uses ultrasound to treat essentialtremors.
