Focused Ultrasound Therapy

Clinical Trials SquareFocused ultrasound is an early-stage, non-invasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with Holmes tremor. This novel technology focuses beams of ultrasonic energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue.

How it Works
Where the beams converge, focused ultrasound produces precise ablation (thermal destruction of tissue) enabling treatment of Holmes tremor without surgery.

The primary options for treatment of Holmes tremor include medications or unilateral thalamotomy.

Some of focused ultrasound advantages include:

  • It is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
  • Focused ultrasound can reach the desired target without damaging surrounding tissue.
  • Focused ultrasound does not require the use of ionizing radiation.
  • It can be repeated, if necessary.

Clinical Trials

At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of Holmes tremor.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for Holmes tremor is not yet approved by regulatory bodies or covered by medical insurance companies.
