UNASSIGNED: Study Design Controlled Laboratory; Repeated Measures. Background PTTD is a common musculoskeletal problem that includes @entity528 of the medial arch of the foot ( @entity85 ). Ankle-foot-orthoses (AFOs) typically are used to correct @entity85 . Correction of @entity85 involves increasing forefoot adduction, @entity1411 , and hindfoot inversion. Objectives To test a foot orthoses with a lateral extension component to determine if it reduces forefoot abduction in @entity1 with Stage II Posterior Tibial @entity409 (PTTD) while walking. Methods The gait of 15 @entity1 with Stage II PTTD was evaluated under 3 conditions; a standard AFO, an AFO with a lateral extension, and a control shoe-only condition. Kinematic variables of interest were evaluated at designated time points in the gait cycle and included hindfoot inversion/eversion, @entity1411 / dorsiflexion, and forefoot abduction/adduction. A 3 x 4 repeated measures ANOVA (brace condition x gait phase) was used to compare variables across conditions. Results The AFO with a lateral extension was associated with a significantly greater change in forefoot adduction compared to the standard AFO (2.6 degrees, p=0.02) and shoe-only conditions (4.1 degrees, p<0.01) across all phases of stance. @entity1411 was significantly increased when comparing the standard AFO and AFO with a lateral extension to the shoe-only condition. The AFO with the lateral extension component also demonstrated significantly increased hindfoot inversion during the loading response and terminal stance phases. Conclusions Off the shelf and standard AFOs have been shown to improve @entity1411 and hindfoot eversion, but not forefoot adduction. A lateral extension added to a standard AFO along the forefoot significantly improved forefoot adduction in @entity1 with PTTD while walking. Level of Evidence Therapy, level 4.
