International Classifications of functioning (ICF) categories were later proposed, with a core-set of 78 (comprehensive) or 35 (brief) categories being recommended for LBP in 2004 [ 76].
Furthermore, the idea of the function decomposition matrix will be presented, and the classification of function decomposition matrices into fully segmented-type function decomposition, shared-type function decomposition, and adjusted-type function decomposition will be discussed.
The definition of MSI took as its starting point the standard WHO International Classification of Function (ICF) definition of impairment as "a loss or abnormality in body structure or physiological function".
A way to classify measurement instruments is the International Classification of Function, Disability and Health Problems ICFF) [ 28].
Measurements reported on ≥1 outcome from the domains within the international classification of function, disability and health, were included.
Since our hypothesis centered on loss of sexual function, each of the outcome measures was categorized according to a binomial classification of function relative to pre-surgical status.
ICF: International Classification of Function [ 34] identifies three health components: impairment of body structure and function; activity limitations; and participation restrictions.
Using the concepts from International Classification of Function (ICF) [ 60], these condition specific questionnaires appear to measure similar constructs, but at different functional levels.
The health care professionals answered questions about their evaluation of the patient's functional limitations, grounded on International Classification of Functioning, Disability and Health ICFF) [ 34].
Moreover, this research paper relied on the International Classification of Functioning, Disability and Health ICFF) as a conceptual framework for describing functional impairments in patients.
