步行功能的喪失，代表病患必須依賴他人照顧，完成生活作息。因此，步態功能訓練是物理治療過程中重要的一環，也是復原程度的重要指標；步態訓練之物理治療理念，採用功能導向型的訓練模式，即動作學習理論，透過重複性方法，反覆地訓練步行過程，以期能重新學習正確的步行動作。早期臨床治療方式，採用平地練走，此種方式造成病患挫折感大、效果不彰。之後，病患使用跑步機結合懸吊系統進行復健缺點包含：腳無法施力抬起放下、踩踏過程膝蓋受到衝擊、跑步機運動步伐曲線不完全符合正常步態及至少需要兩位以上治療人力。
人、機、環系統，是『使用者、操作者＋操作機器＋作業環境』的系統，本研究採用人、機、環系統的分析方式，藉由參與觀察、訪談、問卷得到使用橢圓機復健過程中產生的問題，並歸納成為此系統的功能要素；藉由相關研究資料，歸納出對應的設計準則，並使用AHP對設計準則進行權重分析。
結果得到，橢圓軌跡結合懸吊系統之步態訓練機適合FAC值為1~2之病患，其設計介面首要條件為安全性考量，機構本身要堅固平穩，主機必須提供病患足夠的保護、固定裝置，例如手腳固定帶、轉位扶手等；吊帶、懸吊系統都應具備足夠的安全性、固定性與舒適性，吊帶容易穿脫、調整，減緩病人緊張的心情；治療師協助病患上下機的動線要保持流暢，進行步態訓練時，治療師站立水平面應略低於病患站立水平面。

Stroke patients lose their ambulant ability and depend on other people to take care of their daily life. Therefore, restoration of gait is a major goal in the rehabilitation of stroke patients. Modern concepts favor a task-specific, repetitive approach to walking training; and clear benefit from more intensive therapy has been demonstrated. Traditional therapeutic methods to improve gait include walking on the level ground with appropriate walking aids and with verbal and manual guidance. However, it needs a lot of therapeutic effort. Stroke patients always feel frustration. Treadmill training with partial suspension enables stroke patients to improve their gait ability. The major limitation of treadmill therapy as a daily routine was the effort required by 2 or even 3 therapists in assisting the gait of severely affected subjects setting the paretic limb and controlling the trunk movement.
Man-machine-environment system focuses on the interaction of users, operators, machines and the surrounding environment. By participative observation, interview and questionnaires, we explored in depth the interface problems and extracted design factors from them. The set of design factors were then converted into design criteria which were subsequently weighed by using analytic hierarchy process.
The results showed that the most important design criterion of gait trainer for stroke patients is safety. The gait trainer should be solid stable and provide with enough protection for hands and feet fastening as well as transfer handrail. The suspension should be smooth and steady. The harness should be easily put on and take off, easily adjustable, and felt comfortable. The movement flow of assisting patients on and off the trainer by the therapist should be kept unimpeded
