IntroductionContinuous monitoring

Essential tremor (ET) shows amplitude fluctuations throughout the day, presenting challenges in both clinical and treatment monitoring. Tremor severity is currently evaluated by validated rating scales, which only provide a timely and subjective assessment during a clinical visit. Motor sensors have shown favorable performances in quantifying tremor objectively.


This study demonstrated the feasibility of continuous monitoring of ET for long period during daily activities by a portable nonrestrictive system. This fact could permit a better knowledge of tremor fluctuation patterns and provide clinicians a more objective measure of treatment interventions
