Clinical Trial of a Low-Temperature Plastic Anterior Ankle Foot Orthosis for Children with Habitual Toe Walking

為探討低溫成形前方踝足裝具（low temperature plastic anterior ankle foot orthosis, AFO）對原因不明（習慣性）足尖步行兒童的療效，本研究對6位患童施用該項治療。病童年齡由2歲至6歲，本身沒有神經肌肉異常症狀（neuromuscular disorder），且家屬同意合作讓病童穿著此種AFO，每日穿著5至8小時，療程共3至8週。所有兒童均在治療後進步至踝關節可前屈20度，不再以足尖步行，且追蹤1至2年並無復發現象。此種AFO裝具可以在穿載後赤足步行，故十分適合東方人在屋內不穿鞋子的習慣。且價格低、舒適、打模及修改容易，對習慣性使用足尖走路兒童的矯正只需短期穿戴即達成永久習慣更改，以避免日後病發後跟肌腱縮短而需手術治療的機率。

Six children with idiopathic (habitual) toe walking were fitted with a new type of plastic anterior ankle foot orthosis made from a low-temperature thermoplast. The age of the children ranged from 2 to 6 years and none had an associated neuromuscular disorder. The splint could be taken off and put on at will. The child wore it for a duration of 5 to 8 hours daily for a period of 3 to 8 weeks. At the end of treatment, all children had improved their range of dorsiflexion by at least 20 degrees. No recurrence was found at one to two years follow-up. The orthosis fits on the front of the shin and extends around the malleoli behind the metatarsal heads in the sole of the foot. It allows the child to walk barefoot indoors which is an important feature especially in oriental cultures. This splint is inexpensive, comfortable, easily molded and remolded. It is an alternative form of treatment for toe walking and only a short period of time is needed for treatment. The use of this splint may avoid unnecessary heel cord lengthening surgery.
