The impact of WRMSDs range from minor discomfort to career-ending injuries. In the study by Pike et al, 20% of sonographers who were symptomatic suffered career-ending injuries.4 The onset of WRMSD symptoms occurs as early as six months from the start of employment (15% incidence), increasing to 45% after three years, and as high as 72% after ten years of employment.11 There are also a number of emotional and financial implications for the worker, as well as an impact on co-workers and the employer.
Pain is the most common symptom and may be accompanied by joint stiffness, redness or swelling, and/or muscle tightness. Numbness and tingling may also occur. The progression of symptoms is defined according to stages in Figure 5. The most common injuries among sonographers are carpal and cubital tunnel syndrome, epicondylitis of the elbow, shoulder capsulitis and tendonitis, and neck and back strains. In a 2009 sample by Evans et al, 90% of sonographers reported shoulder pain, with 69% reporting low back pain and more than half (54%) reporting work related symptoms of the hand and wrist.6
It is difficult to successfully treat WRMSDs if reporting is delayed or the worker is sent back to the same work environment that produced the initial injury. Therefore, early reporting of symptoms and efforts to prevent injuries is critically important. The first onset of pain is a signal that the muscles and tendons need to rest and recover. Otherwise, an injury can become longstanding, and sometimes, irreversible.
