摘要

本研究主要在探討中高齡者下肢運動的活動型態與輔助產品設計，針對缺乏活動的膝、髖關節向度發展出中高齡者下肢運動輔具產品，達到關節活動完整性，進而評估設計的可行性。因此，本研究以下肢運動來帶動膝、髖關節活動，做為研究方向，從生物力學角度，探討膝、髖關節的結構與運動型態分析，發展下肢運動輔具產品。研究結果包含以下三個部分：

(1)運動型態分析：針對中高齡者日常運動時之動作，依其下肢動作進行運動型態分析探討。從研究分析中發現外轉、內轉與內收三動作向度為中高齡者普遍較缺乏活動之動作角度，因此，將其設定為產品欲加強發展部分。

(2)設計發展：與復健治療專家擬定下肢運動輔具產品之設計方針，分別為關節多向度運動、舒緩下肢疼痛效用、簡潔輕巧不複雜、使用操作簡單、易於攜帶與安全操作方式不吃力六項，根據設計分針發展構想與模型打樣。

(3)產品驗證評估：以使用性評估準則之有效性與滿意度兩者作為驗證實驗評估。由結果得知透過本設計的訓練使用，對於膝、髖關節各向度皆獲得改善，其中以外轉與內轉兩者前後的關節角度差異最為明顯。此外，訓練後成效並未因性別、左右關節差異而有所影響。另外從主觀滿意度分析得知，三層面以使用操作評比滿意度較高，分別為使用操作>整體>外觀。

This study aims to discuss the lower limbs exercise types and product design for the middle-aged. For the knee and hip joints’ lacked for movement of range of motion, the study develops a lower limbs assistive product. In addition to achieving the joints of movement for its completeness, it evaluates the feasibility of the design. Therefore, the study draws up the lower limbs exercise to drive the movement of knee and hip joints as the research direction. Then, it investigates into the structure of knee and hip joints, and analyzes the exercise types from the aspect of biomechanics. Finally, it develops the lower limbs assistive product. The results of experiment are divided into three sections:

(1)Analysis of exercise type : The analysis method is used to measure the middle-aged’s lower limbs movement in the activities of daily livings. In this investigation, the motions of external rotation, internal rotation and adduction generally lack movement of range of motion for the middle-aged. Therefore, these motions are regarded as intensive development of product design.

(2)Product design: The guiding principles of design are according to the discussion with the physiatrics expert. The guiding principles are the complete range of motion, relieving pain of the lower limbs, brief and easy not complicated, easy to use, easy to carry and the safe operation. Then, it is based on these guiding principles to develop ideas and prototyping.

(3)Evaluation and verify for design: Using effectiveness experimentation and questionnaire survey of subjective verify for design. In this investigation, the range of motion (rom) of the knee and the hip joints are improving by using the design. The rom of external rotation and internal rotation are obviously difference between before use and after use. In addition, the result of rom doesn't get influence between the gender and the both sides of joints. In questionnaire survey of subjective, the subject gets most high score of evaluation for operation. The score of evaluation are the operation > the entirety of design > the appearance.
