Some systems use a 2 day approach why is this not the case with the Matheson System?
The Matheson FCE focuses on tolerance within the course of one day. The rationale for this is to insure that prolonged positional tolerances and consistency of performance can be adequately assessed under the observation of the clinical evaluator. This approach avoids the need for extrapolation formulas, which are unproven to date, and when translated to the actual work environment can place the injured worker at risk of re-injury.
