受控实验室，重复测量。胫后肌腱功能障碍是一种常见的肌肉骨骼问题，包括肌腱变性和足内侧弓塌陷（扁平足畸形）。踝足矫形器（afo）通常用于矫正平足畸形。平足畸形的矫正包括增加前足内收、前足足底屈曲和后足内翻。测试具有侧伸的足部矫形器是否能减少II期胫后肌腱功能障碍患者行走时的前足外展。15名II期胫骨后肌腱功能障碍患者的步态在3种情况下进行评估：标准AFO，外侧延伸AFO和仅穿鞋对照条件。在步态周期的指定时间点评估感兴趣的运动学变量，包括后脚内翻/外翻、前脚足底屈曲/背屈和前脚外展/内收。采用3 × 4的重复测量方差分析（按步态阶段进行支架状态）来比较不同条件下的变量。与标准AFO（2.6°，P = 0.02）和仅穿鞋的AFO（4.1°，P< 0.01）相比，侧伸的AFO在站立的所有阶段导致前足内收的显著变化。将标准AFO与侧伸的AFO与仅穿鞋的AFO进行比较，前足足底屈曲明显增加。侧伸的AFO在负荷响应和站立末期也表现出明显的后足内翻。现成的和标准的afo已被证明可以改善前足足底屈曲和后足外翻，但不能改善前足内收。在标准AFO的基础上沿前足进行侧伸，可显著改善行走时胫后肌腱功能障碍患者的前足内收。
Controlled laboratory, repeated measures. Posterior tibial tendon dysfunction is a common musculoskeletal problem that includes tendon degeneration and collapse of the medial arch of the foot (flatfoot deformity). Ankle-foot orthoses (AFOs) typically are used to correct flatfoot deformity. Correction of flatfoot deformity involves increasing forefoot adduction, forefoot plantar flexion, and hindfoot inversion. To test whether a foot orthosis with a lateral extension reduces forefoot abduction in patients with stage II posterior tibial tendon dysfunction while walking. The gait of 15 participants with stage II posterior tibial tendon dysfunction was evaluated under 3 conditions: a standard AFO, an AFO with a lateral extension, and a shoe-only control condition. Kinematic variables of interest were evaluated at designated time points in the gait cycle and included hindfoot inversion/eversion, forefoot plantar flexion/dorsiflexion, and forefoot abduction/adduction. A 3-by-4, repeated-measures analysis of variance (brace condition by gait phase) was used to compare variables across conditions. The AFO with a lateral extension resulted in a significantly greater change in forefoot adduction compared to the standard AFO (2.6°, P = .02) and shoe-only conditions (4.1°, P<.01) across all phases of stance. Forefoot plantar flexion 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 also demonstrated significantly increased hindfoot inversion during the loading response and terminal stance phases. Off-the-shelf and standard AFOs have been shown to improve forefoot plantar flexion and hindfoot eversion, but not forefoot adduction. A lateral extension added to a standard AFO along the forefoot significantly improved forefoot adduction in participants with posterior tibial tendon dysfunction while walking.
