Non-Invasive Neuromodulation for Essential Tremor: Long-Term Safety and Effectiveness Study
A Prospective, Single-Center, Single-Arm, Open-Label Clinical Study Evaluating the Long-Term Safety and Efficacy of Transcutaneous Afferent Patterned Stimulation (TAPS) in Patients With Essential Tremor
This is a prospective, single-center, single-arm, open-label clinical study designed to evaluate the long-term efficacy and safety of non-invasive neuromodulation using transcutaneous afferent patterned stimulation (TAPS) in patients with essential tremor (ET).
Essential tremor is a common movement disorder that can significantly impair daily functioning and quality of life. Pharmacological treatments are often limited by suboptimal efficacy or adverse effects, highlighting the need for alternative therapeutic approaches.
In this study, eligible participants with essential tremor will receive TAPS treatment over a defined follow-up period. Clinical outcomes, including tremor severity, functional performance, and patient-reported outcomes, will be assessed longitudinally to evaluate treatment effectiveness. Safety will be monitored throughout the study by recording adverse events and device-related complications.
The results of this study aim to provide clinical evidence regarding the long-term therapeutic potential and safety profile of TAPS as a non-invasive neuromodulation strategy for essential tremor.

Change in Activities of Daily Living (Blessed Functional Activities of Daily Living [BF-ADL] Score)
Prazo: Baseline; Day 1; 1 month; 3 months
|
Change in activities of daily living from baseline to each post-treatment time point, assessed using the Blessed Functional Activities of Daily Living Scale (BF-ADL).
The BF-ADL score ranges from 0 to 17, with higher scores indicating greater functional impairment.
