Validity and reliability of a new device to simulate upper extremity work demands.
The device validity, intra-test reliability, and test-retest reliability of the LIDO WorkSET(TM) (Loredan Biomedical, West Sacramento, California) was studied. Subjects were 30 healthy incumbent workers at a manufacturing and warehousing facility. The results of this study demonstrate a very high degree of device validity in terms of torque measurements, power, and work. In addition, the test protocols were found to be reliable on an intra-test and inter-test basis. Finally, inter-test comparisons were found to be stable over time.
