Biomechanical Aspects regarding Restoration of Shoulder Stability in Athletes

Abstract

Although the recovery of the body after exertion or post-trauma is particularly important, in contemporary sports, for various reasons, it is often not given the necessary time. The main objective of the research was to study the biomechanical particularities of the shoulder that ensure mobility and stability in order to recover post-luxation. The research activity was carried out on two athletes, during 8 months, and we followed the restoration of muscle imbalances and the biomechanical analysis of the unstable shoulder. The objectives of the research were to select the most effective methods and means of physical therapy, by which to restore the stability of the post-luxation shoulder, in athletes. As working methods we used exercises performed in a closed kinematic chain and neuromuscular and proprioceptive facilitation techniques, balancing the forces of the deep muscles. In conclusion, it can be said that through isometric work in a closed kinematic chain and through neuromuscular and proprioceptive facilitation techniques, we can balance the stabilizing muscle forces at the level of the shoulder joint. Through the recovery sessions performed, the muscle imbalances were diminished by the considerable increase in the muscle strength of the per articular muscles.
