Academic debate on ICF and a theory of social productivity 247 is not whether consumptive and productive activities can be approached without being normative. The ques- tion is whether they should be considered important for the human being, and consequently introduced in the ICF as central issues of participation. If this is true, the approach to them should not be normative as correctly proposed. Jerome Bickenbach indicated that he does not see a difference between activity and participation, which for him is a continuum. We probably need more clarity on this matter. In fact, one could argue that a difference clearly comes from the most important point he raised, i.e. that we must not be normative in the ICF. As physicians, the absence of norms can be considered true only for participa- tion (better or worse mobility should be judged only by the patient themself), while we absolutely need to be normative in activities, measuring and defining what is the “normal” activity for a human being as a reference to judge the presence or not of an activity limitation. In this sense, for physicians there is a clear distinction between activity and participation, and this should be maintained. For Negrini this also explains why the PRM specialty is clearly primarily focused on activities and impairments, while participation is ultimately the goal, but not one of our main fields of competence. itself, e.g. the problem of not classifying personal factors and to not distinguish between activities and participation. • There was no doubt that there is a need for scienti- fic theories to describe functioning and health. The theory of social productivity seems to be an important contribution towards this goal. However, here some major questions have been raised: • The definition of well-being (and quality of life) in relation to the operationalization of functioning and health needs to be further developed. The theory of social productivity provides one approach, but other approaches seem to be necessary. • The theory of social productivity addresses one important factor to operationalize functioning; however, the questions remains unanswered as to whether other (additional) approaches are needed and whether this theory is applicable across cultures. CONCLUSION The authors would like to thank the members of the European Academy of Rehabilitation Medicine for their participation in the debate in Budapest, September 2016: Kristian Borg, Anne Chamberlain, Gabor Fazekas, Charles Gobelet, Alvydas Juoce- vicius, Jaro Karppinen, Gustaaf Lankhorst, Angela McNamara, Xanthi Michail, Johan Rietman, Joao Pascoa Pinheiro, Jean Paysant, Diane Playford, Bengt Sjölund, Henk Stam, Gerold Stucki, Brigitte Perrouin-Verbe, Mauro Zampolini. All in all, the first structured academic debate within the EARM focussed on a very relevant topic: is it pos- sible to provide a theory neutral framework to describe the lived experience of health, or is there an appropriate theory to understand what constitute the most relevant factors of health (and well-being) (and how they can be operationalized). The ICF provides a framework to operationalize health and functioning and is supposed to be “theory neutral”. The emerging questions from the debate relate to 2 main issues: • The independence of the ICF model from any theory must be further elucidated both in reviewing the pro- cess of its development including comparisons with already existing theories on health and participation, and in demonstrating its feasibility to be used in dif- ferent theories on health and participation as well as in different settings and cultures. • With regard to the feasibility of the use of the ICF, it seems that the efforts to make the classification more user-friendly should continue. In addition, some questions about the ICF remain open, e.g. whether it can be understood across cultures. Last, but not least, the debate showed some issues of the classification Last, but not least, the conclusion cannot be an “either- or” (classification vs theory). More work should be invested and projects should be set up both to further develop the ICF and refine (or develop new) theories. Further debates, scientific projects and symposia around these topics should be organized. ACKNOWLEDGEMENTS The authors have no conflicts of interest to declare. REFERENCES 1.
