Johnson et al evaluated the effect of deep dermal burns on the range of motion for a finger. The Total Active Motion (TAM) Rating Scale can be used to categorize the level of impairment.
(1) maximal flexion of the distal interphalangeal joint (DIP)
(2) maximal flexion of the proximal interphalangeal joint (PIP)
(3) maximal flexion of the metacarpophalangeal joint (MCP)
(4) loss in full extension of the distal interphalangeal joint (DIP)
(5) loss in full extension of the proximal interphalangeal joint (PIP)
(6) loss in full extension of the metacarpophalangeal joint (MCP)
The maximum angle for each joint is measured separately. Ideally the finger in extension is straight and the finger can be flexed into a tight curl. An inability to fully extend a finger is considered the loss of extension.
Degrees When Normal
extension loss DIP
extension loss PIP
extension loss MCP
total active motion in degrees =
= SUM(degrees of flexion for the 3 joints) - SUM(loss of extension for the 3 joints)
• maximum TAM: around 260 degrees
• minimum TAM: < 60 degrees
220 to 259 degrees
180 to 219
< 180 degrees
• I am not sure how a TAM of 220 to 259 qualifies for being excellent (good maybe, with 180 to 219 fair).
