Overview

Subacromial pain syndrome is one of the most common musculoskeletal health conditions, causing decreased of range of motion, loss of muscle strength and disability in the shoulder region. It has been proposed that dynamic humeral centering exercises could contribute to overcome these disorders, through the modification of the dimensions of the subacromial space, however, there is no consensus on its effectiveness nor direct variables that account for its efficacy. Therefore, the aim of this research is to determine the effects of a dynamic humeral centering exercise program on the functionality and disability of patients with subacromial pain syndrome.The effects of the dynamic humeral head exercises program, as well as the objective description of factors and variables associated with subacromial pain syndrome, will also allow rehabilitation science professionals to aim their interventions according to the knowledge of direct variables, which will allow objective follow-up of interventions on subacromial pain syndrome diagnosed patients.
