However, “I would regard the results as preliminary and would need confirmation and study in a larger series of patients,” he added. “Furthermore, the stimulation was done in the operating room for 1 hour [with patients] under general anesthesia. This is a significant period of time, and to be clinically useful, there needs to be a more efficient way to deliver the treatments.”
Dr. Armstrong concluded: “I consider this thought provoking and a technique that may be useful to help rehabilitate spinal accessory nerve weakness, and it may have applicability for other cranial nerves. It will require further study.” ■
