Objectives: After studying the article entitled "Variation of Pinch and Grip Force between Different Size Transducers: A Preliminary Study " you will be able to:
determine the relationship between transducer size and force exerted when scanning
describe the three commonly measured types of inch strength
determine characteristic factors that make scanning of patients challenging
Of sonographers that report work-related musculoskeletal pain, those that report severe pain constitute about
20% 40% 80-85% > 90%
Significant contributing factors to the prevalence of work-related musculoskeletal disorders in sonographers include
repetitive motions isometric muscle contractions awkward body positions all of the above
Of those shown below, the most significant contributing factor to hand and wrist strain is
transducer design right versus left handedness sitting versus standing while scanning height of the examination stretcher
In the study reported, the most common sites of pain that was noted were the
wrist, neck and shoulder wrist, neck and back arm, neck and shoulder back, neck and shoulder
A research study on cylindrical-shaped handles has reported the diameter best suited to minimize grip force should be
27mm 30mm 33mm 54mm
In the study reported, correlation was seen between pre-existing pain and
low grip strength and low sensor pressure high grip strength and high sensor pressure low grip strength and high sensor pressure high grip strength and low sensor pressure
In the study reported, correlation was seen between pain while scanning and
high overall force exerted low overall force exerted high overall pinch strength high three-jaw chuck pinch strength
The digit which produced the overall highest measured pressures while scanning was the
thumb index finger middle finger ring finger
An adequate time interval of rest to recover hand stability after heavy lifting is
5-10 minutes 10-20 minutes 15-30 minutes 30-45 minutes
Highest maximum forces while scanning were typically associated with
the large transducer the small transducer scanning with the dominant (right) hand scanning with the non-dominant hand
