  1. Prevalence of 'some tenderness' and 'severe tenderness' - as well as the total prevalence of tenderness (total = some + severe; note that not all sums match due to rounding) - of 8 selected anatomical locations in the 198 generally healthy office workers with frequent neck/shoulder pain. The anatomical locations are ranked in descending order of the tenderness score for women. Average scores (0-2) are calculated as the average right and left score, where some tenderness = 1 and severe tenderness = 2. Between-location and between-gender differences were based on ANOVA's of the tenderness scores (0-2).
  2. *: sign.diff. from deltoideus
  3. #: sign.diff. from supraspinatus
  4. $: sign.diff. from occipital border
  5. £: sign.diff. from trapezius
  6. &: sign.diff. from infraspinatus.
