How to Use This Calculator

Enter Maximum Lift, Carry Distance, and Standing Tolerance.
Set Walking Tolerance and Sitting Tolerance.
Review Lift Category ((1=Sedentary, 2=Light, 3=Medium, 4=Heavy, 5=Very Heavy)) and Overall Capacity Score (/ 100).
Use Work Restriction Level ((1=None, 2=Light Duty, 3=Modified, 4=Unable)) to inform your decision.

What each input means

Maximum Lift: Maximum weight the patient can safely lift in pounds.
Carry Distance: Maximum distance the patient can carry a load in feet.
Standing Tolerance: How long the patient can stand continuously in minutes.
Walking Tolerance: How long the patient can walk continuously in minutes.
Sitting Tolerance: How long the patient can sit continuously in minutes.
