My husband had C2-T1 surgery 4 months ago. A side effect was left arm palsy (did not have it pre-surgery). He's being treated by an OT to make sure that he doesn't get frozen shoulder. He also sees an acupuncturist and has limited physical therapy. Surgeon says it usually resolves after 6 months but we are getting nervous. Is there any other treatments we can do to help his arm palsy? Parenthetically, he also has significant leg weakness and balance issues still (which he had pre-surgery).
