We compared VFC and registry participation lists to perform initial classifications of participation status; this initial status was confirmed by 62% of respondents to both the non-participant and participant surveys.
In the whole process of the unsupervised classification, there is no classification of sample participation, and the common used algorithms are K-Means and ISODATA.
Another unsolved conflict is the supraordinal classification of the domains activity and participation.
A recently published paper [ 29] has given an alternative classification of nodes based on their participation in control.
These include ladder models [ 16, 17], continuums or steps, each using different methods to describe levels of participation [ 18], and classifications of the type of involvement [ 19- 21].
The purpose of this study was to compare the content of participation instruments using the ICF classification.
The SF-6D classification system includes six multilevel dimensions (physical functioning, role of participation, social functioning, bodily pain, mental health, and vitality) and describes 18,000 health states [ 35].
To validate the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-Participation) in persons with spinal cord injury (SCI) using 2 International Classification of Functioning, Disability and Health (ICF -based ICF -baseds: the instruments of PartheICF Measure Activities-Screener (IMPACT-S) and the Wofld Health Organization Disability Assessment Schedule II (WHODAS II).
Impact was defined as impairment, activity limitations and participation restriction (International Classification of Functioning, Disability and Health (ICF)).
A classification tree (pruned on misclassification) was grown to identify useful cutpoints for the potential predictors of participation.
In his classification, "people participation level" is the horizontal axis, and "people," as one of the sources of proposal, is one category on the vertical axis.
