LOINC long common name : Percent impairment - confidence [OPTIMAL];
LOINC description : The OPTIMAL percent impairment should be calculated independently for difficulty and
confidence questions. Both the difficulty and confidence percent impairment can be
calculated based on the patient's answers to all 22 movement items, to the three items
the patient chooses as most important to be able to do without difficulty, or to a
single item that the patient chooses as most important. The percent impairment can
be mapped to the Centers for Medicare and Medicaid Services (CMS) Impairment Limitation
Restriction G-codes, which are required for reporting to CMS. [http://www.apta.org/OPTIMAL/];
