ABSTRACT
Introduction: Scapular dyskinesis is defined as a abnormal of position and/or motion of the scapula. The scapula is the connection between the trunk and the upper superior, an analysis of transmission variables is important for a better understanding of the kinetic chain. Purpose: to evaluate the head, shoulders, and thoracic spine; muscle flexibility; range of motion and strength of the cervical and thoracolumbar spine musculature in asymptomatic individuals. Methods: Fifty-two individuals were divided into two groups: with scapular dyskinesis (22.95 ± 2.86) and without scapular dyskinesis (age 22.06 ± 2.73). Dyskinesis was assessed using the Scapular Dyskinesia Test. A biophotogrammetry was used for a postural analysis. The Pectoralis Minor Index and the Levator Scapulae Index were used to assess muscle flexibility. The digital inclinometer was used to evaluate the range of motion of flexion, extension, lateral flexion and rotation of the cervical spine; and flexion, extension and flexion of the thoracolumbar spine. The handheld dynamometer was used to evaluate the muscle strength of the flexor, extensor and flexor lateral cervical and thoracolumbar muscles. The inter-examiner variable samples were a concordance that varied from good to almost perfect. Results: The difference (p> 0.05) between the groups was not observed for any of the variables. Conclusion: This results can be used as a growing doby of evidence that scapular dyskinesis to be prevalent and can be classified as a normal variation of human movement for this population.
