Cala Trio therapy is a groundbreaking treatment designed to temporarily and effectively reduce your hand tremor. It is the first and only non-invasive therapy that directly targets the source of the tremor by gently stimulating the wrist nerves with electricity (neuromodulation) and targeting the root cause of essential tremor.1

The Cala Trio device is FDA-cleared, safe, effective, and individually calibrated to each patient's unique brain signal pattern.1–3
How it works

1Cala Trio therapy measures your specific tremor.

2Gentle stimulation is sent to the median and radial nerves, traveling to the brain.

3The stimulation interrupts the tremor in the brain's ventral intermediate nucleus of the thalamus.

68%

68% of patients who self-rated as having “Severe or Moderate” difficulty in their activities of daily living self-rated as “Mild” or better at the end of the study. Patients reported using Bain-Finley Activities of Daily Living (BF-ADL).1

94 minutes

64% of patients reported persistent relief for an average of 94 minutes (standard deviation = 138; median = 60).1

Real World Evidence
Data analyzed from 22 months of real world use confirms prior clinical studies showing Cala Trio therapy effectively reduces tremor with no loss of effect over time and improves patient quality of life for those living with essential tremor (ET).5

Contraindications: Cala Trio therapy should NOT be used by patients with an implanted electrical medical device, those with suspected or diagnosed epilepsy or other seizure disorders, or used on the treated wrist with diseased skin (e.g., swollen, infected, inflamed areas, or open wounds), or by patients who are or may be pregnant.
