Intra-rater reliability was > 0.75 for all ICC measures except the ePT (tester A) day 2 for hip extension, internal rotation seated, knee extension, and ankle dorsiflexion; nPT (tester B) day 1 knee flexion; and SPT (tester C) for day 1 knee extension and ankle eversion and days 1 and 2 for ankle dorsiflexion and inversion. It is concluded that HHD can reliably measure force production of hip, knee, and ankle muscle groups without use of external fixation devices.This study investigated the prevalence of perfectionism among young female competitive Irish dancers and examined the relationships between perfectionistic tendencies and coping strategies used when experiencing injury. Sixty-eight female dancers (Mean age 14 ± 2.3 years) completed the Child-Adolescent Perfectionism Scale and the Ways of Coping Questionnaire and provided a record of injuries incurred during their championship careers. Participants reported 189 injuries, mostly involving the lower extremities. Seventy-nine percent of dancers reported perfectionistic tendencies (mixed perfectionism 40%, pure self-oriented perfectionism 29%, pure socially prescribed perfectionism 10%), and most frequently adopted "planful problem-solving," "seeking social support," "distancing," and "self-controlling" strategies to cope with injury. Perfectionism and two coping strategies were found to be significantly related (p = 0.03); "planful problem-solving" was typically used "quite a bit or a great deal" by the mixed perfectionism group, but only "somewhat" by the non-perfectionism group, whereas "confrontive coping" was typically not used by the non-perfectionism group but was used "somewhat" by the mixed perfectionism group. Given the presence of such a large degree of perfectionism and the simultaneous employment of problem- and emotion-focused strategies when coping with
