Local Vibrational Therapy for Essential Tremor Reduction: A Clinical Study

Area of Science:

• Neurology
• Biomedical Engineering
• Medical Devices

Background:

• Essential Tremor (ET) is an involuntary movement disorder impacting quality of life.
• Pharmacotherapy is the current standard treatment for ET.
• Innovative interventions are needed to manage ET symptoms effectively.

Purpose of the Study:

• To evaluate the tremor reduction efficacy of an innovative medical device (IMD) in Essential Tremor patients.
• To assess the safety and functional outcomes associated with the IMD.
• To investigate the impact of local hand-arm vibration therapy on tremor severity.

Main Methods:

• A prospective, single-center, single-arm pragmatic study was conducted.
• The study involved 17 Essential Tremor patients in the main efficacy assessment.
• An extended safety study included 51 patients with Essential Tremor or Parkinsonian tremor.

Main Results:

• The device use resulted in a statistically significant reduction in tremor power spectrum (p=0.027).
• In the extended safety study, 48/51 patients reported improved tremor symptoms and 49/51 improved function.
• No serious adverse events were reported; some patients experienced lack of efficacy or increased tremor.

Conclusions:

• The vibrational medical device shows potential for reducing essential tremor in a subset of patients.
• The device is safe for use in Essential Tremor patients.
• Further research may explore personalized treatment approaches for optimal outcomes.
