目前針對下肢失能患者所開發的階梯移行輔具產品相當昂貴，且不普及。許多患者在居家環境面臨階梯或樓層障礙時，多半將其活動空間限制於居家平面部份或進行環境改造，結果不僅造成患者居家活動空間減少，也影響其生活品質。本研究主要針對下肢失能患者在居家環境的階梯移行提供新的構想，在增加階梯支撐底面積與可調整雙手支撐位置的概念下，研發設計一組簡易、實用、安全且便宜的階梯移行輔具。期望患者在不需要進行居家環境改造下，也能達到居家階梯移行無障礙的目的，以提升其生活品質。

Commercial locomotion devices for stairs negotiation are now expensive and not available. House adaptation or limitation of living space to ground floor will be the common choice for the patients who encounter great difficulties in climbing stairs at own home, Consequently, it would condense the daily activity space of ground floor for other family members and decreases their quality of life. In this study, we tried to design a convenient, practical, protected, and inexpensive advice for stair climbing underlying an idea of both increasing the stairs' base of support and being capable of adjusting the positions of hand Support. We hope it could help the patients with lower limbs dysfunction to negotiate stairs independently and safely without need for adapting their home environment.
