Stepien et al reported the Lichen Planus Activity and Damage Index (LiPADI). This measures disease activity and damage in various body sites. The authors are from Rzeszow University and Medical University of Lublin in Poland.
LiPADI subparts:
(1) skin activity
(2) activity at other site (mucous membranes and hair)
(3) damage at all sites
Skin anatomic locations:
(1) scalp
(2) face
(3) chest
(4) abdomen
(5) back and buttocks
(6) arms
(7) hands
(8) legs
(9) feet
Parameters for the most severely affected lichen planus lesion:
(1) erythema
(2) hypertrophy
(3) scale

subscore for each location =
= SUM(points for all of the parameters)
total score for skin activity =
= SUM(points for all locations)
Interpretation:
• minimum subscore for a location: 0
• maximum subscore for a location: 6
• maximum for hypertrophy: 9
• maximum for erythema: 27
• maximum for hypertrophy: 18
• maximum total score for skin activity: 54
