Berger then investigated patients that consulted for Bell’s palsy with early stages of the condition and the Stimpod NMS460 was investigated to ascertain if changes in nerve conduction were possible. All patients had been administered with medication. Muscle grading tests were given initially to determine the status of each patient. When the Stimpod NMS460 was applied to the main facial nerve as it exited the stylomastoid foramen through the parotid gland and the branches of the nerve into the face (opthalmic, maxillary, mandibular), it was noted that even in muscles that had limited activity (0/5), there was immediate albeit weak initial stimulation. This was actively maintained immediately post-treatment and when the patient returned for the second treatment, voluntary facial movements had all improved.
