Aim of the study: To determine the relationships between scapular dyskinesis, shoulder pain, disability and quality of life. Tasks of work: 1. To analyze the literature and select scientific articles that examine the relationship between scapular dyskinesis and shoulder pain, disability and quality of life; 2. To determine the relation between scapular dyskinesis and shoulder pain; 3. To evaluate the relation between scapular dyskinesis, disability and quality of life. Methodology of investigation: The systematic literature review was written in accordance with the PRISMA (Preferred Reporting Item for Systematic Review and Meta-Analyzes) systematic literature review. Searching for scientific articles in the PubMed and Web of Science databases. The search for scientific articles was carried out according to the date of publication of the research, which had to correspond to the years 2013 - 2023. The number of publications selected by keyword combinations was 237 of which 10 publications were included in the systematic literature review after selection according to the criteria of inclusion and exclusion of the systematic literature review. Results: Non-randomized studies showed that scapular dyskinesis could be observed in both subjects with and without shoulder pain (p=0,51; p=0,09), after evaluating all studies in the systematic literature that assessed scapular dyskinesis and shoulder pain. Also, scapular dyskinesis had a statistically significant reduction in one of the seven assessed tests (p=0,022; p=0,013; p=0,018; p=0,004; p=0,000) in studies where subjects had a statistically significant reduction in pain over time (p=0,022; p=0,013; p=0,018). Interventions such as physical therapy exercise, massage, manual therapy, dry needling therapy, improves scapular dyskinesis outcomes and reduce pain scores, in randomized controlled trials. Three of the four non-randomized studies did not find associations between disability, scapular dyskinesis and shoulder pain. It was found that interventions improve disability outcomes with other assessed outcomes, in randomized controlled trials, but improvements in disability outcomes may have been due to reduced pain and improved muscle function. Conclusions: 1.After searching the scientific literature and selecting the scientific articles and applying the inclusion and exclusion criteria, there was total 10 scientific publications, 3 of them was randomized controlled trials, and 7 non-randomized analytical observational studies examining the associations between scapular dyskinesis, shoulder pain and disability, were included in the systematic literature review. 2. Analytical observational studies shows that scapular dyskinesis are more common in subjects with established shoulder pain as well as in healthy subjects without shoulder pain. Pain decreases over time even without interventions, but scapular dyskinesis do not change. Meanwhile, randomized controlled trials shows that interventions reduces both pain and scapular dyskinesis. 3. To evaluate the associations between scapular dyskinesis, disability, and quality of life, were obtained different results: a) Most of the non-randomized studies did not show associations between scapular dyskinesis and disability. However, it has been observed that changes in scapular muscle activity may be associated with functional arm disability. b) Randomized clinical trials showed that all assessed indicators of scapular dyskinesis and disability showed changes after the interventions. However, we cannot conclude that these aspects have associations. c) Studies examining associations of quality of life with scapular dyskinesia, shoulder pain, and disability were not found in this systematic review. |
