Abstract
A cross-sectional representative sample of 1722 sonographers and vascular technologists was analyzed using quantitative/qualitative methods to reveal that 60% are experiencing wrist-hand-finger discomfort, believed to be from work-related repetitive injury. The years of scanning accumulated by the participants was chosen as a variable to determine the relationship to the range of discomforts reported. A strong statistical correlation was noted between years of experience and the side of discomfort as well as the severity of hand-wrist-finger discomfort. In this study, a strong statistical association was also noted between increasing years of scanning and decreasing aggravation due to the transducer. A complete linkage between work-related exposure and hand-wrist-finger discomfort is difficult to make because of the contribution of leisure-time activities. A controlled experimental study is needed to determine the contribution that grip and pushing on the transducer may have on the incidence of hand-wrist-finger discomfort, leading to diagnoses such as carpal tunnel syndrome.
