本研究目的為檢視腿前式踝足矯具 (anterior ankle-foot orthosis, AAFO) 在中風 患者站立之靜態及動態平衡的效果，以平衡儀 (Balance Master) 的感覺組合測驗 (Sensory Organization Test) 及穩定限度測驗 (Limit of Stability Test) 作為研究工具， 使用壓力中心數據計算靜態站立穩定度、對稱性、重心轉移最大移動範圍及重心 轉移後最大患側承重比率。本研究採重複量測之實驗設計，共24位中風患者參與 研究，評量穿戴及不穿戴AAFO在感覺組合及穩定限度測驗之表現，使用配對t檢 定比較有無穿戴AAFO在上述測驗之差異情形。結果顯示中風患者穿戴AAFO在 穩定限度測驗中，身體重心轉移至患側斜前方 (p < .001) 及患側 (p = .002) 之最大 移動範圍顯著增加。此外，中風患者穿戴AAFO重心轉移至患側 (p = .003) 及患側 斜後方(p < .001) 後之最大患側承重比率顯著增加。但中風患者穿戴AAFO於感覺 組合測驗評量之站立穩定度及站立對稱性無顯著差異 (p > .01)。本研究發現中風 患者穿戴腿前式踝足矯具能夠改善重心轉移至患側時之患側方向穩定限度範圍與 承重。因此，建議中風患者可穿戴AAFO來執行重心轉移之活動以增進其動態平 衡表現。

The objective of this study was to examine the effects of anterior ankle-foot orthosis (AAFO) on the static and dynamic balance of standing in stroke patients. Static and dynamic balance were measured by the Sensory Organization Test (SOT) and the Limit of Stability (LOS) test of the SMART Balance Master. Stance stability, stance symmetry, maximal weight-shi ing distance and maximal a ected side weight-bearing percentage were calculated  om center of pressure (COP) measures. Twenty-four stroke subjects participated in a repeated measures study.  e static and dynamic balance of the subjects were measured with and without an AAFO. Paired t-tests were used to determine the difference between balance performance with and without an AAFO.  e results show that stance stability and stance symmetry measured by the SOT did not improve when the subjects wore an AAFO (p < .01).  ere were signi cant increases in the maximal distance of weight shi ing toward the a ected-forward (p < .001) and the a ected side (p = .002) during the LOS test.  ere were also signi cant increases in the maximal a ected weight-bearing percentage a er weight shi ing toward the a ected side (p = .003) and the a ected-backward side (p < .001) during the LOS test.  is study revealed that the stroke subjects wearing an AAFO could improve the maximal distance of the limit of stability and the percentage of weight bearing of the affected side during weight shifting toward the affected side. Therefore, we suggest stroke patients should wear an AAFO to improve dynamic balance performance during weightshi  ing activities.
