Shoulder Issues and the Rotator Cuff
The rotator cuff are a group of four muscles connecting between the shoulder blade and upper arm. The function of these muscles are to lift the arm away from the body, internally/ externally rotate and very importantly to stabilise the head of the upper arm in the socket. Compared with the hip joint the ball and socket of the shoulder is much shallower and relies on this muscular support as we lift and weight bare and hang through our arms.
Anyone that uses power tools regularly where you are constantly internally and externally rotating can suffer overuse of these relatively small muscles so it is good to both stretch and strengthen them. I will post a video to my vitalitysportsmassage facebook page and linkedin.
