A professional hockey player came to me for a persistent heavy sensation in her right arm. The patient presented with some shoulder, upper back and right side neck pain from playing the sport. I asked her to show me how to make a shot and noticed how her right scapula just wasn’t rotating properly. The patient told me that she usually carried her heavy hockey bag on the right shoulder too! I was instantly reminded of a conversation that Matt at Sports Medicine.Acupuncture had with us during a lecture in San Diego about what muscles that are usually affected in Thoracic Outlet Syndrome. I worked on the motor point of scalene muscle, then added a set of motor points of muscles to free up the sticky rotation of her scapula. At this point, the patient felt her shoulder and arm immediately relaxed. It was when I worked on motor points of serratus anterior muscle, the patient said she felt the relief going from her armpit all the way down to the fingers.
