Study links Cala's wrist stimulation for tremor to changes in deep brain activity
Published in Brain Stimulation, the work found the non-invasive therapy affects the same thalamic region targeted by deep brain stimulation.
A study from the University of Wisconsin–Madison, published in Brain Stimulation, examined how Cala’s wrist-worn TAPS therapy reduces tremor in essential tremor. The researchers recorded brain activity in people who already had deep brain stimulation leads. Tremor reduction correlated with changes in alpha and beta rhythms in the thalamus, the region that surgical DBS targets.
The findings suggest a wearable nerve stimulator can influence the same circuits as brain surgery, giving a mechanism behind a non-invasive tremor treatment.
