My wife, a trumpet player, recently had rotor-cuff surgery on her right shoulder. She won't be able to even pick up a horn for many weeks; in the mean time she's thinking about her trumpet playing more abstractly than she could while playing regularly. One surprise we saw on the video recording of the arthroscopic surgery was a hole in a rotator-cuff tendon that the body had filled-in with fat. The doctor removed the fat deposit and bound the two major strands together so the weakened tendon would heal back into one strong tendon. There was much more damage to her RC that had weakened her right arm, and we are convinced her arm will become stronger than it has been in many years. The degree of weakness her shoulder reached over many years of progressive injury has made her reconsider the cause of the right-hand tremor she has experienced for a couple of years. Debilitating conditions like Parkinson's have already been ruled out by the doctors. The tremor has only been in her hand -- ESPECIALLY when in trumpet-playing position. Has anyone heard of shoulder weakness being related to arm or hand tremor in trumpet players?
