It appears that this form is a summary for case closure regarding the use of an FCE. It makes reference to research from Snook (our maximum occasional lifting evaluation) and infers that extrapolation can be used to estimate a client's ability to lift in some, somewhat abstract, categories referred to as "Never, Seldom, Occasional, Frequent and Continuously". This form also assigns repetitions for each category regarding material handling. To my knowledge, no research has been produced that validates anything other than "Occasional, Frequent and Constant" (the EPIC Lift evaluation). I believe this is expressed in percentages of a workday (following DOT guidelines). Unfortunately, I am not yet a certified EPIC evaluator.

I would caution an evaluator against using extrapolation, and if an EPIC protocol is not available, suggest using both the Snook and PILE evaluations to derive at Occasional and Frequent abilities, respectively. For assessing an individuals ability to perform "Continuous" lifting capacities, I would recommend a work simulation circuit using materials/shapes/movement patterns that replicate the task in question.

To directly answer the question as to how to arrive at extrapolated values, one would take percentages of a known value (i.e.; Max Occasional) and "extrapolate" the percentages listed (80, 70, 50%). How, why or with what reference this equates into repetitions, eludes me. Others as well, I'm sure. If known values per hour are known through a well documented job description, I would use that as a work simulation in an FCE. What could be better?
