Some new aspects of the functional anatomy of the shoulder.
The authors investigated the functional role of the shoulder muscles in various active movements using simultaneous polymyographic recordings. Ten muscles were investigated in both normal subjects and in patients with pathological conditions. Ten patients were also studied during the course of operations for nonrelated conditions by "tetanizing" stimulation of nerves to individual muscles to determine their action as single muscles.
