The Influence of Kinetic Chain Sequencing on Throwing Performance in Athletes with and without Shoulder Injury

Researchers: Mr Liam Owens (PhD), Professor Mehmet Dorak, Associate Professor Omid Alizadehkhaiyat and Dr Ginny Coyles

The prevalence of shoulder injuries have been widely documented, with a high prevalence in overhead throwing sports. Shoulder injuries contribute to approximately 10% of all athletic injuries and this can be attributed to the importance of throwing at high speed as this usually influences the outcome in a number of sports. The Kinetic Chain plays an important role within overhead throwing action, involving the transfer of energy in a sequence from the lower body, through the muscles of the core and into the upper body. Due to the intense nature of maximal throwing, breakdowns in this sequence are common. The forces that result can put excessive strain on the shoulder joint and due to its’ anatomical make-up, can result in an injury or failure. Common injuries include Shoulder Instability, Shoulder Impingement and Rotator Cuff Tear. These injuries are common across a number of overhead throwing sports, namely Handball and Baseball.
Therefore, the main aim of this study is to identify muscle activation patterns in combination with kinematic sequencing of movement in overhead athletes. The main focus will be identify differences in this sequencing pattern between athletes who have had a shoulder injury in their throwing shoulder previously and athlete who have no shoulder injury prevalence.
The study aims to investigate differences in overhead throwing between injured and non-injured athletes, as well as the key muscle activation patterns involved in numerous rehabilitation exercises for shoulder injury. From the study, recommendations regarding differences in overhead throwing mechanics and relationships for exercise provision will be targeted. The potential to quantify the effectiveness of rehabilitation exercise provision will allow a prehabilitative outlook to be formed for minimising shoulder injury prevalence.
