拜託請幫幫忙翻這段句子

Having established the outline designs for each of the four types of knee orthoses, the other requirements which must be taken into account in compiling the detail designs must be con-sidered. The most significant of these are the problems of attaching the orthosis securely to the leg. As the lower limb essentially tapers from hip to ankle, knee orthosis have a ten-dency to slip distally under the action of gravity and the inertial forces generated at heel-strike. This will lead to misalignment of knee joint hinges with a subsequent reduction in knee flexion and sometimes also significant discom-fort. A compromise therefore needs to be sought between attaching the orthosis too lightly to the limb and hence risking slippage of the device, and strapping the orthosis so firmly that it is uncomfortable. It has been in an attempt to circumvent such difficulties that techniques such as suspension from a hip or waistband, or the attachment of the orthosis to below-knee elements anchored in the shoe have been tried.

    已經建立了四個類型的膝蓋矯正器的外型輪廓設計圖,其它必須被考慮到的需求在編輯詳細的設計時也應該深思熟慮。其中最重要的是將矯正器安全地裝附到腿上的相關問題。

    實質上人體的下肢從臀部到腳踝逐漸變細,膝蓋矯正器在地吸引力的作用下有向末端滑動的傾向,以及慣力產生在腳跟撞擊點。這將導致膝蓋連接樞紐的錯誤結合並削減接著發生的膝蓋彎曲幅度,而且有時也相當令人感到不舒服。需要在「較鬆地裝附矯正器於肢體上」及「因此承擔矯正器裝置下滑的風險」之中尋找一個妥協折衷的方式,並且若綁附矯正器過於牢固是令人不舒服的。

    有一些技術被試圖用來防止這些難題的發生,例如從臀部或腰間懸吊,或是矯正器的附加裝置在膝蓋部位底下被固定在鞋子上。
