How to Use This Calculator
  1. Enter Upper Extremity Impairment, Lower Extremity Impairment, and Spine Impairment.
  2. Review Combined WPI (%) and ADL Impact ((1=Minimal, 2=Mild, 3=Moderate, 4=Severe, 5=Total)).
  3. Use Functional Loss (%) to inform your decision.

What each input means

Upper Extremity Impairment
Whole person impairment percentage for upper extremity (shoulder, arm, hand) per AMA Guides.
Lower Extremity Impairment
Whole person impairment percentage for lower extremity (hip, knee, ankle, foot) per AMA Guides.
Spine Impairment
Whole person impairment percentage for spine (cervical, thoracic, lumbar) per AMA Guides.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Upper Extremity Impairment = 15, Lower Extremity Impairment = 10, Spine Impairment = 8 = 3 input(s) provided
  2. Calculate Combined WPI
    Combined WPI
    29.6 = 29.6%
  3. Calculate ADL Impact
    ADL Impact
    2 = 2
  4. Calculate Functional Loss
    Functional Loss
    29.6 = 29.6%
