Chronic Pain Management

"As a chronic pain coach myself I have to say that it is amazing! The visual biofeedback is a really intuitive way to implement calming techniques such as breathwork and see how it affects your nervous system in real time." -Simone H.

“Such a wonderful product! My colleagues and I are big fans and recommend them for our patients who are struggling with pain and anxiety.” -Ericka Dickson, LCSW

Supports

Therapy Practices

"Utilizing the Calmstone during a therapy session was an awesome experience for myself and my client. In real-time we were able to track their baseline physiological state and track progress to achieve calm utilizing Calmstone’s visual feedback light indicators. Typically, we base progress with emotional regulation on self-reporting, but Calmstone actually provides feedback in-vivo for the client and therapist to record. Utilizing Calmstone regularly can provide regular exercise for the client to learn to master emotional regulation through controlled breathing and other coping techniques. It is truly an awesome device that is handheld and convenient to use in therapy practice." - Jacob Cordero, MS
