简要总结
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.
详细描述
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.

结局指标
主要结局
Tremor power changes from pre-stimulation to post-stimulation
时间窗: baseline, pre-intervention and immediately after the intervention
Tremor improvement was measured by Tremor Power Improvement Ratio (TPIR) using kinematic data collected by the device. The TPIR was calculated as pre-stimulation power divided by post-stimulation power, which was computed from device-collected accelerometer data
次要结局
- Change in BF-ADL(baseline, pre-intervention and immediately after the intervention)
- Change in UPDRS Part III from pre-stimulation to post- stimulation within each visit(baseline, pre-intervention and immediately after the intervention)
- Change in TETRAS from pre-stimulation to post- stimulation within each visit(baseline, pre-intervention and immediately after the intervention)
