Prevalence of carpal tunnel syndrome and other work-related musculoskeletal problems in cardiac sonographers.

Cardiac sonographers at a regional medical center have experienced carpal tunnel syndrome symptoms and other work-related musculoskeletal injuries. The nationwide incidence of these problems was not known. A questionnaire pertaining to possible causes of work-related injuries was developed and distributed to 225 cardiac sonographers. A 47% response rate was achieved with 72% female respondents. Eighty-six percent reported one or more physical symptoms. Only 3% of respondents had been diagnosed with carpal tunnel syndrome. Posture correlated significantly with other work-related musculoskeletal injuries. High-pressure hand grip correlated significantly with carpal tunnel syndrome symptoms. No other strong relations with physical symptoms were found. The contribution of specific factors to musculoskeletal problems experienced by cardiac sonographers was difficult to determine.
