Ethics approval and consent to participate
: The current study was approved by the local ethical committees of the four-evaluation centres. For Clinique romande de réadaptation, the “Commission Cantonale Valaisanne d’Ethique Médicale” (n° CCVEM 050/12), for France (two centres) and the “Comité d’Ethique de l’Institut Régional de Médecine Physique et Réadaptation”; for Portugal, “Comissao de Etica para a Saude do Hospital Particular de Algarve” (n° 1/2013) gave consent. All patients received an information sheet about the study and signed an informed consent if they were included.
: The individuals featured in the protocol (supplementary material pages 6 and 22) consented to participate to the study. The consent form did not include the consent to publish, so the two photos were cropped to maintain anonymity. All the other photos were taken by occupational therapists and concerned the hands of occupational therapists.
