TENDON

Total Active Motion [ASSH]

The TAM of a finger is the total active ROM of the MCP, PIP and DIP joints. This is most often calculated by measuring the joint angles in full active flexion and the joint angles in full active extension. The difference in these angles is the TAM.

Strickland Criteria

An ordinal scale, rating the outcome from ‘Excellent’ to ‘Poor’ based on the return of motion.

Buck – Gramcko Method

This method is based on the evaluation of the TAM, the extension deficit and the pulp-to-crease distance. The maximum score is 15, with better scores for better function.
