^a ≤ 27 kg in men, ≤ 16 kg in women at hand-held dynamometer

^bThe subject does not refer the exact date (day/month/year)

^cThe words “bread-house-cat” are referred to the subject at the beginning of the questionnaire and then asked to the subject at this time of the questionnaire

All the binary variables have been coded using “0” to indicate the absence and “1” the presence of a deficit, except for the items 9 and 10 where the absence of help corresponds to “1” and the presence of help to “0”
