The SFMA is a diagnostic system that is broken down into seven (7) Top Tier tests that are graded as Functional Painful (FP), Functional Non-painful (FN), Dysfunctional Painful (DP), Dysfunctional Non-painful (DN). Should a Top Tier test not pass a grade of FN, then that specific movement will be broken down further to the find the root cause of the dysfunction. This “root cause” can either stem from tissue, joint, or stability/motor control issues.
