D-CMDQ German version of the Cornell Musculoskeletal Discomfort Questionnaire, κ Cohen’s Kappa, κ/κmax proportion of maximum kappa achieved, p _pos proportion of positive agreement, p _neg proportion of negative agreement, P _O proportion of observed agreement; * Variable at the second measurement point was a constant (all subjects reported “no pain”). For these body regions a relative Kappa (κ/κmax) could not be calculated. # p_pos could not be calculated as nil positive responses on either testing occasion
