Non-Invasive Neuromodulation for Essential Tremor: Long-Term Safety and Effectiveness Study

2026年8月17日 更新者：Ruijin Hospital

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.

主要结果指标

结果测量
措施说明
大体时间
Change in Tremor Severity (The Essential Tremor Rating Assessment Scale [TETRAS] Score)
大体时间：Baseline; Day 1; 1 month; 3 months
Change in tremor severity from baseline to each post-treatment time point, assessed using the The Essential Tremor Rating Assessment Scale (TETRAS). The TETRAS score ranges from 0 to 64, with higher scores indicating more severe tremor.
Baseline; Day 1; 1 month; 3 months
Incidence of Adverse Events
大体时间：3 months
Incidence, type, and severity of adverse events occurring after treatment initiation. Adverse events will be graded according to standard criteria (e.g., CTCAE)
3 months

次要结果测量

结果测量
措施说明
大体时间
Change in Activities of Daily Living (Blessed Functional Activities of Daily Living [BF-ADL] Score)
大体时间：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.
Baseline; Day 1; 1 month; 3 months
Change in Anxiety Severity (Hamilton Anxiety Rating Scale [HAMA])
大体时间：Baseline; 1 month; 3 months
Change in anxiety severity from baseline to each post-treatment time point, assessed using the Hamilton Anxiety Rating Scale (HAMA). The HAMA score ranges from 0 to 56, with higher scores indicating more severe anxiety.
Baseline; 1 month; 3 months
Change in Depression Severity (Hamilton Depression Rating Scale [HAMD])
大体时间：Baseline; 1 month; 3 months
Change in depression severity from baseline to each post-treatment time point, assessed using the Hamilton Depression Rating Scale (HAMD). The HAMD score ranges from 0 to 52, with higher scores indicating more severe depression.
Baseline; 1 month; 3 months
Change in Cognitive Function (Montreal Cognitive Assessment [MoCA])
大体时间：Baseline; 1 month; 3 months
Change in cognitive function from baseline to each post-treatment time point, assessed using the Montreal Cognitive Assessment (MoCA). The MoCA score ranges from 0 to 30, with higher scores indicating better cognitive function.
