[The Frühreha-Index (FRI): a manual for its operationalization].

The Frühreha-Index (FRI) was first described by Schönle 1995 to complement the established Barthel-Index in the early phase of inpatient neurological rehabilitation. The dichotomic scale was designed to allow for a simple determination of the seven items for each patient. In the authors' experience, however, inclusion and exclusion criteria are necessary to define each item correctly. The aim of the work presented therefore was to operationalize the items of the FRI. The operationalized criteria are described in detail, and their limitations are discussed.
