Talk to your Doctor about Cala Trio
The Cala Trio therapy is prescribed by a physician. It is indicated to aid in the transient relief of hand tremors in the treated hand following stimulation in adults with essential tremor.
Essential tremor (ET) is a common movement disorder affecting over 7 million Americans.1 The condition is marked by primarily hand tremors that make it difficult, if not impossible, to perform daily activities like eating, drinking, and writing.
Symptoms2 of essential tremor include:
- Uncontrollable shaking that occurs when you use your hands
- Shaking voice
- Nodding head
- Tremors that get worse with emotional stress
- Tremors that get worse with intentional movement
- Tremors that lessen with rest
If essential tremor makes it difficult to perform daily activities, there are treatment options including:
- Physical or Occupational therapy
- Brain surgery
Now a breakthrough in essential tremor is here.
Cala Trio has a wrist band that delivers electrical stimulation to the nerves in the wrist. The stimulation disrupts the tremor network in the brain and delivers meaningful tremor reduction in the treated hand. An effective, safe tremor therapy is here.
Your life and your experience with essential tremor are unique. Finally, an individualized treatment is here.
