Many jobs in industry place severe demands on the worker's musculoskeletal system--demands that may approach or exceed worker voluntary strength capabilities. There is evidence to suggest that such jobs increase the likelihood that the worker will experience a musculoskeletal disorder. For this reason, a great deal of effort has been focused recently on developing methods to evaluate muscular strength capabilities of workers, both for purposes of ergonomic job design and for developing worker selection procedures. However, the necessity of using indirect measures of muscular strength makes its assessment quite complex, which has sometimes led to confusion and misunderstanding about appropriate uses of strength measurement techniques. The chapter provides information about the appropriate procedures for measuring and reporting of strength test results for three common measurement techniques used in ergonomics: isometric, isoinertial, and psychophysical. It is hoped that the information in this chapter will provide the reader with a better understanding of the advantages, disadvantages, caveats, and limitations associated with the use of these strength assessment techniques.
