Empty Can Test

Good Essays

"Anatomy is to physiology as geography is to history; it describes the theatre of events", was once stated by a French physician, Jean Fernel. Further elaborating on this concept, it is essential to understand the basics of shoulder anatomy before understanding what the empty can test is. It is also inherent to the future of the medical field that when these tests are conducted, they are supported with scientific research and evidence. This cannot be accomplished if the validity and reliability of the test are inconclusive. The empty can test is a test of the supraspinatus muscle, which is part of the shoulder muscle group known as the rotator cuff. This muscle stabilizes the shoulder joint. It originates on the supraspinous fossa of the scapula and inserts onto the greater tubercle of the humerus. The chief action of this muscle is abduction of the humerus (Marieb, 2014, p. 209). When testing the integrity of the supraspinatus muscle, the assessor is looking for …show more content…

All research shows that all tests conducted and possible differences within each test still lead to similar conclusions. With two different studies that both utilized electromyography as the primary distinction of the activation of the supraspinatus during the empty can test, this can give physical therapists and patients confidence that the validity of the test is tremendously accurate. All of the electromygraphy results deemed the supraspinatus strongly isolated during this test which is a sturdy indication that the test is valid. The third study shown is best in demonstrating the reliability of the empty can test. With the results being so similar in the two clinicians testing, this shows the test to be reliable. This test could have been made even more accurate had there been more clinicians to perform the test with their results compared to each
