N2  - RESUMEN: Hyperpronation is a common foot problem in dancers. The aim of the study was to investigate the susage and effectiveness of orthotics in the management of symptomatic hyperpronation among dancers. A prospective cohort study of all dancer-patients in the investigators practice who were precribed orthotics for new symptoms related to hyperpronation between July 2008 and Juanuary 2009 was conducted. In this group, the longitudinal medial arch angle of the foot was measured by the Foot Build Registration System (FBRS), both barefootl and while wearing the orthotics. In addition, patients filles out questionnaires addressing perceived effectiveness of the orthotics for pain redution and dance ability, among other items. A second retrospective study was conducted in  orger to obtain longitudinal data regarding dancers´ compliance with, and subjective evaluation of, wearing orthotics over the preceding 6 years. A mong participating dancers who met criteria for the prospective (N= 24) or retrospective (N= 81) aspects of the study (total N=105), 67 % wore orthotics at the time of follow-up. The average compliance in usage was 6.0 (+-1.5) days per week and 7.5 (+-3) hours per day. The average rate of satisfaction was 67.9 (+-26  .5), average degree of relief in symptons was 58.3 (+-28.3), and self-reported degree of improvement in dance ability was 45.7 (+-27.9), on a 100 mm Visual Analogue Scale (VAS). There was a significant decrease in pain from the day of orthotics prescription to follow-up (25.9% or 18.9 mm decrease on the VAS, CI 6.6-30.9 ,p = 0.005) in the prospective group (N=24). Orthotics were found to decrease the medial longitudinal arch angle significanly during static stance with the orthotic in place (CI 0.08- 1.65,p= 0.03) It is concluded that the dancers in this study demonstrated a high rate of compliance in obtaining and wearing their orthotics and experienced a significant decrease in pain.
