Effectiveness of Prefabricated and Customized Foot Orthoses Made From Low-Cost Foam for Noncomplicated Plantar Fasciitis: A Randomized Controlled Trial

      Abstract

      Baldassin V, Gomes CR, Beraldo PS. Effectiveness of prefabricated and customized foot orthoses made from low-cost foam for noncomplicated plantar fasciitis: a randomized controlled trial.

      Objectives

      To evaluate the effectiveness of prefabricated and customized foot orthoses made from low-cost foam (ethylene vinyl acetate [EVA]) in plantar fasciitis.

      Design

      Double-blinded randomized controlled trial.

      Setting

      Public rehabilitation referral medical center.

      Participants

      One hundred forty-two adults (75% women) with plantar fasciitis, without anatomical alterations in the feet. Seventeen subjects (12%) were lost during the follow-up.

      Interventions

      Prefabricated and customized foot orthoses, both made from EVA, used for 8 weeks.

      Main Outcome Measures

      The primary outcome was pain (modified subscale of the Foot Function Index, [FFI] pain). The secondary outcomes were pain elicited by palpation in the medial calcaneal tuberosity and modified FFI total. Each participant was reviewed in the 4th and 8th weeks of follow-up.

      Results

      One hundred twenty-five participants returned to at least 1 of the follow-up evaluations (63 in the prefabricated and 62 in the customized groups). There was a significant improvement in both groups (P<.05), but there was no difference of modified FFI pain between intragroup differences at 4 (4.03 points; 95% confidence interval [CI], −4.2 to 12.3) and 8 weeks (3.93 points; 95% CI, −4.6 to 12.5).

      Conclusions

      The low-cost prefabricated and customized foot orthoses, as used in this trial, had similar effectiveness in the treatment of noncomplicated plantar fasciitis after 8 weeks of use. Our results were similar to other trials, although those trials did not use orthoses made from EVA. Thus, EVA prefabricated inserts may be the best choice for the treatment of plantar fasciitis without complication.
