The committee will review new or improved diagnostic or evaluative techniques for assessing physical disabling impairments in the Cardiovascular, Neurological, Respiratory, Hematological, and Digestive body systems. The committee should describe accepted uses for each technique as well as date the technique became available. The technique should offer diagnostic information of a nature previously unavailable or that is substantially more precise than earlier techniques. These techniques should have the potential to show that a previously evaluated impairment was either more or less severe than was found before. For further information please see Project Scope.
