Evidence-Based Classification

Competition in Paralympic sport is based on systems of classification. The Classification Code of the International Paralympic Committee (IPC), mandates the development of evidence-based systems in all para-sports to improve the validity of Paralympic classification. An evidence-based system is one in which the purpose of the system is stated unambiguously; empirical evidence indicates the methods used for assigning classes will achieve the stated purpose.

Evidence-based practice is a growing movement in the health and educational disciplines that recommends an emphasis on research outcomes during decision-making in practice. Evidence-based is made possible through evidence-based research, which attempts to synthesize the volume and scientific rigor of intervention effectiveness.

The vision of the Paralympic movement is “to enable Paralympic Athletes to achieve sporting excellence and inspire and excite the World” and evidence-based classification systems are critical for fully realizing this vision.

Aims:

• Provide ideas to suppport and improve the classification system used for IFCPF sports by evidence-based research.
• Develop Research questions that can be used by researchers for future research programs/proposals. Particularly related to classification of athletes that meet the current IFCPF classification rules.
• Monitor international research of classification in paralympic sport and in particular for athletes with CP, ABI and other neurological conditions similar to the athletes that meet the minimum criteria for IFCPF classification system.
• Establish collaborations with other research groups, individuals and/or sport federations which are working in the field of evidencedbased classification research.
• Communication of results and reports, representing IFCPF at scientific meetings related with sports for persons with disabilities. 

Evidence-Based Classification and Research in CP-Football:

The current classification system is based on a combination of different approaches (i.e., quantitative/qualitative) in line with evidence-based practices and according to the International Paralympic Committee Classification Code. From 2012-2013 when CP football was governed by the Cerebral Palsy International Sports and Recreation Association (CPISRA) to the transition to an independent specific para-sport international federation (IFCPF), the approach has been to meet the compliance of the International Paralympic Committee Classification Code with evidence-based methods.

The CP football classification committee and the rest of the organization, members, collaborators, and para-athletes have been important efforts to meet the requirements of the Code. These efforts are traduced in different research and academic work supporting the classification system which transfers all this knowledge to practical methods during the class allocation of para footballers.

The following section is presented the available scientific literature on the topic, infographics, and posters/lectures presented at international conferences:
