About

Demonstrate safety and effectiveness of symptomatic action tremor relief in the treated hand following stimulation with the Cala Trio System using the Trio+ bands as compared to the Trio bands in adults with Essential Tremor (ET) and/or Parkinson's Disease (PD) over 2 weeks.

Full description

20 patients with (13 with ET and 7 with PD) with at least mild postural tremor were enrolled in a prospective, single-center, two-arm, crossover study that took place over the course of four weeks. TAPS devices were shipped to patients to run the study remotely. In the first arm of the study, subjects received TAPS treatment using the original. Cala Trio band for two weeks. Followed by a wash-out period (> 24 hours), subjects entered the second arm and received TAPS using the Trio+ band for an additional two weeks. Unsupervised motion assessments were captured at home, and at the beginning and end of the four weeks by telemedicine.
