Concurrent Validity of the ERGOS Work Simulator Versus Conventional Functional Capacity Evaluation Techniques in a Workers??? Compensation Population

The Concurrent Validity of the ERGOS™Work Simulator and the Ergo-Kit®with Respect to Maximum Lifting Capacity

“…One of these found the ERGOS TM Work Simulator and conventional FCE techniques with respect to dynamic lower and upper lifting to have moderate concurrent validity (9). The other study found poor concurrent validity for the Isernhagen Work Systems FCE as compared to several disability questionnaires (16).…”

“…Finally, we encountered two other studies that examine the concurrent validity of FCE methods (9,16). One of these found the ERGOS TM Work Simulator and conventional FCE techniques with respect to dynamic lower and upper lifting to have moderate concurrent validity (9).…”

“…However, no studies were found on the reliability of the Ergo-Kit  . Only one study compared the results of different FCE methods (9). Dusik et al (9) demonstrated moderate relationships for the concurrent validity of the ERGOS TM Work Simulator and conventional FCE techniques with respect to dynamic lower and upper lifting.…”

Practical Aspects of Functional Capacity Evaluations

“…One of the most comprehensive investigations of RTW criterion validity was conducted by Dusik et al (10). They compared FCE results using a standardized testing protocol for job simulation, and then followed RTW outcomes of a functional rehabilitation program postdischarge.…”

An examination of the perceptions of functional capacity evaluations in Prince George, British Columbia: A case study.

“…There have been concerns identified specifically in regards to basing the physical assessment on the Dictionary o f Occupational Titles. Dusik, Menard, Cooke, Fairbum, and Beach (1993) commented that the validity of the Dictionary of Occupational Titles physical characteristics were unknown. Ten years later, Frings-Dresen and Sluiter (2003) noted that the reliability and validity o f the Dictionary of Occupational Titles physical characteristics remains questionable and related this concern directly to its impact on the validity of the Functional Capacity Evaluations.…”
