  1. Values are n, mean and ± one standard deviation, except for Duration, for which median and range values are presented. The NDI and TSK scores are normalized to the range of 0 to 100. BMI: Body Mass Index; SF-36 PCS: Short Form 36 physical component summary; SF-36 MCS: Short Form 36 mental component summary; Physical activity: How physically active at leisure time have you been in the last year? (1-6); VAS pain: Visual analogue scale rating of pain (100 mm); NRS pain: Numerical rating scale of pain (0-10); NDI: Neck Disability Index; TSK: TAMPA Scale of Kinesiophobia; NA: Not answered.
