From: The relationship between cervical flexor endurance, cervical extensor endurance, VAS, and disability in subjects with neck pain

  1. Differences between groups were analyzed with a Student unpaired t test*, a Mann–Whitney U test**, or a Chi-square test*** as appropriate.
  2. aThe categories for the characteristic “symptoms localization” are: upper cervical spine/lower cervical spine/trapezius muscle and shoulder/two areas/three areas.
  3. bThe categories for the characteristic “frequency” are: sometimes/often/constant.
  4. cThe categories for the characteristic “other symptoms” are: no symptoms/headache/vertigo or dizziness/headache and other.
