The Stabilizer Pressure Biofeedback Unit is designed for both lumbar and cervical spine exercises. The device provides a valuable Bio-feedback loop to your patients. This assists you in training your patients to selectively isolate and contract core stabilization muscles. Patients with weak core muscles or spinal instabilities benefit in particular because the feedback effectively helps the patient make the necessary muscle to brain connections, therefore strengthening the intrinsic core muscles to the spine. Pain is reduced and the likelihood of re-injury is lessened as well. The device has a measuring accuracy of +/- 3 mnHz pressure.
