Treatments We offer

While pain medication is helpful for some of our patients, we offer many non-medicinal options for managing the pain, including, but not limited to, the treatments listed below. Our physicians are leaders in the field of neuromodulation, which involves the electrical stimulation of the central nervous system to help manage pain and other chronic conditions.

We are committed to “whole patient health care,” and in addition to the advanced pain therapies we offer, we work with many patients on nutrition, exercise, physical therapy, smoking cessation and other health and wellness programs.

TMS at Neurovations

TMS works by using short, magnetic pulses to stimulate the nerve cells in the parts of the brain believed to regulate mood and emotions. TMS stands for Transcranial Magnetic Stimulation. It is a non-medication, non-invasive therapy cleared by the FDA for the treatment of depression in patients who were unsuccessful with other methods of treatment. This treatment has helped thousands of patients find relief and gain back control of their life.
