The BNS-40 is a miniaturized version of the Myomonitor designed to allow the patient to safely apply electrical stimulation while at home to relax tense muscles. It is a battery operated, ultra-low frequency electrical stimulator designed specifically for the dentalpatient. It is ideally suited when prescribed for the following purposes: Temporomandibular Disorders and associated pain Relieving symptoms associated with muscle spasm Relaxing orofacial muscles Increasing local blood circulation Increasing mandibular range of motion Dr. Barry Cooper of New York says, "I find muscle hyperactivity to be a key element in most tension headache/TMD patients. I utilize the BNS-40 for these patients in the office and often prescribe it for home use to treat the muscular components. These patients experience dramatic relief, and acute episodes of the underlying conditions diminish. We have several units in our office and they are in use constantly."
