Robinson reported a computation chart in 1973 for calculating the percent impairment to the individual with a significant skin disorder.

total percent impairment =
= SUM((percent of body region) * (percent of subtotal) * (percent whole body))
Purpose: To estimate the impairment to the patient caused by a skin disorder by the distribution of significant lesions.
Specialty: Sports Medicine & Rehabilitation, Dermatology
Objective: disability and performance
ICD-10: L98, L99,
