  1. First main complaint was selected, TSK subscale Activity Avoidance (items 1,2, 9,10, 13, 14, 15, 17),
  2. TSK subscale Harm (items 3, 5, 6, 7, 11).
  3. RDQ = Roland Disability Questionnaire, MC = Main Complaint, VAS = Visual Analog rating Scale, IPA = Impact on Participation and Autonomy, TSK = Tama Scale for Kinesiophobia, SF-36 = Short Form-36.
