Graduated Work Hardening In each program module, aerobic exercises decrease as work     simulation increases. Includes body mechanics and exercise instruction, as well as     structured work simulations. Individualized over a 2 to 6 week program. Functional Capacity Evaluation Assess physical functioning for lifting, carrying, pushing, pulling,     and extremity use. Use of the computerized Ergos Work Simulator for objective     measurements. Accomplished over a 4 to 6 hour period. Work Tolerance Screening Includes provision of an initial Functional Capacity Evaluation to     determine baseline physical tolerances. Structured job-specific activities to determine vocational     feasibility. Conducted in 2 or 3 day modules.
