The self-administered questionnaire was designed to elicit general information on age, gender, years of
practice, work and employment setting, and patient population. Musculoskeletal and LBP problems were
addressed by 5 multiple choice questions on lifetime prevalence, sickleave, treatment of LBP. We did not
include duration of symptoms as a criterion. The last question was an open one. The respondents were asked
about other musculoskeletal problems which in their opinion are related to the PT practice.
