\"QuickConceptsSeries_Screen_FINAL\u201c[It] is a great fallacy: the Wisdom of [Age]. They do not grow wise. <\/em><\/strong><\/p>\n

They grow careful.<\/em>\u201d<\/strong><\/p>\n

That quotation, taken from Ernest Hemingway\u2019s A Farewell to Arms<\/strong> carries a deeper meaning for ultrasound\/sonographic professionals<\/a> insomuch as a lack of attention to ergonomics early in your career can result in a later \u201cFarewell\u201d to musculoskeletal<\/a> comfort in your arms, shoulders and wrist.<\/p>\n

\"posture\"25%<\/strong> of sonographers end their careers in scanning based on injuries sustained as a result of the \u201cwear and tear\u201d associated to the occupation<\/a>.\u00a0 Admittedly, your body is more resilient to misuse in your twenties and thirties.\u00a0 However, without precautions one finds this becomes less true over time.<\/p>\n

Developing good ergonomics is a practice best embraced early in one\u2019s scanning career.\u00a0 Sadly, many people \u201csee the light\u201d only after pain and discomfort arise.\u00a0 With that in mind, we outline a Top-5 list of habits to adopt in the video below.<\/p>\n

\"cantilever-faliure\"For those of you fascinated by the underlying physical principles, the science behind this is also illustrated in studying cantilevers<\/strong>.\u00a0 Your arm, attached to the trunk of your body by the shoulder, operates as a cantilever when the arm is extended. The weight of your arm is generally around 5-6% of your total body weight on average.\u00a0 Accordingly, we are lifting at least that 7-9lbs and exerting greater forces of tension\/shear as it approaches 90% (perpendicular) to the body trunk.<\/p>\n

\"shoulder-muscles\"Stated another way, the higher you raise your arm and the farther away you reach, the more stress and strain your shoulder endures. It should, therefore, seem clear that keeping our arm at lower angles (less than 300<\/sup>), and the patient closer to us will reduce those stress forces operating against our shoulders.<\/p>\n

Following good ergonomics and preventative measures will help you avoid ending your sonographic career prematurely.<\/strong><\/p>\n
