Cala Trio patient stories

 

 

The Science

Surface stimulation delivered at your wrist is thought to disrupt the central tremor network in your brain that causes the hand tremor.

  • Developed through Clinical Studies
  • Reduces tremor for an average of 96 minutes after stimulating1
  • 50% reduction in tremor was reported by 54% of users1
  1. The stimulation interrupts the tremor in the ventral intermediate nucleus of the thalamus part of the brain
  2. Gentle stimulation is sent to the median and radial nerves, traveling to the brain
  3. Cala Trio measures your specific tremor

Cala Trio is indicated to aid in the transient relief of hand tremors in the treated hand following stimulation in adults with essential tremor. Please refer to the Safety Information for a complete listing of warnings and cautions.
