Objectives: After studying the article entitled “Upper Extremity Kinematics in Sonographers During Kidney Scanning,” you will be able to:
Describe the musculoskeletal injuries that frequently affect sonographers
Determine the underlying causes of these injuries
Describe the postures and positions that put significant stress on the upper extremities when scanning
The most recent published data suggest that approximately what percentage of sonographers scan in pain? 60% 70% 80% 90%
Fatigue, reduced blood flow, and the potential for repetitive stress injury occur when the shoulder is persistently abducted during scanning to greater than 20 degrees 30 degrees 40 degrees 50 degrees
Sonographers in the study tended to have larger ranges of shoulder motion when they Sat Stood Twisted their torso Leaned forward
Compared to scanning while standing, average shoulder flexion noted in this study for seated scans was approximately The same Twice as much Three times as much Five times as much
Published acceptable limits for wrist extension during scanning are 0 to 15 degrees 0 to 20 degrees 10 to 20 degrees 15 to 25 degrees
Average wrist extension by sonographers during this study, compared to the acceptable upper limit, was found to be approximately The same Double Triple Four times as much
The number of sonographer subjects who experienced external shoulder rotation in this study was 1 2 3 4
Flexion of the elbow joint was experienced by how many of the sonographer subjects in this study? 1 2 3 4
Ultrasound transducer design had the greatest effect on differences for Maximum shoulder flexion Maximum shoulder abduction Maximum elbow flexion Maximum wrist flexion
Based on the results of this study, the majority of time, sonographers tend to scan with their shoulders in Flexion, abduction, and external rotation Flexion, abduction, and internal rotation Extension, abduction, and external rotation Extension, abduction, and internal rotation
