The results are presented as mean ± SD or as n and %. Pain group was analyzed with chi² tests
NRS, numeric rating scale; PHV, peak height velocity; CMJ-AS, counter-movement jump with arm swing
^aAnalyzed with chi² test. Boys vs. girls, p = 0.005
^bRange for boys were 2–7 regions and for girls 2–12 regions
^cScored from best to worst
^dScored from worst to best. EQ-5D was dichotomized according to the best tertiary (1.00) vs. the two worst tertiaries (< 1.00)
