WebThe stress–strain index (SSI), of a bone, is a surrogate measure of bone strength determined from a cross-sectional scan by QCT or pQCT (radiological scan). The stress–strain index is used to compare the structural parameters determined by analysis of QCT/pQCT cross-sectional scans to the results of three-point bending test. WebAug 20, 2002 · A: The Strain Index is a tool used to evaluate a job’s level of risk for developing a disorder of the hand, wrist, forearm, or elbow. The analyst evaluates six task variables (intensity of exertion, duration of exertion, exertions per minute, hand/wrist posture, speed of work, and duration of task per day). The task variable is given a value ...
