  1. The selected outcomes were based mainly on the recommendations of IMMPACT. Mean values (SD) together with statistical analyses Pre vs. FU-12 (*p < .00083) and effect sizes (Cohen’s d) are presented. For the ratings of global improvements are reported percentages (%). Retro-pain = Changes in perception of pain; Retro-life situation = changes in life in general. The variables were trichotomized into improved, no change, and worsened (%)
