Posterior tibial tendon dysfunction (PTTD), which results in painful pes planus, is a common clinical problem that requires careful orthotic management. The purpose of this study was to conduct a chart review and telephone survey to determine the effectiveness of orthotic treatment. In this preliminary study the authors define effective orthotic treatment as treatment that reduces pain and assists the patient in returning to pre-PTTD activity levels. When comparing orthotic management among foot orthoses fabricated from cork and pelite, UCB-type foot orthoses, and various types of AFOs, strong trends were noted. UCBs andAFOs reduced pain in five and seven subjects respectively, but only AFO management successfully increased activity levels of the subjects.
