摘要: | 肌肉組織是否強健會直接影響日常生活機能,應適當的予以鍛鍊,防止肌力逐漸衰弱,透過阻力運動(resistance exercise)可增強肌肉的強度與耐久力。本論文提出一個具有上肢特定肌肉強化與傷害防護訓練機的設計,不僅可提供健康的使用者作肌肉強度的訓練且可幫助肌肉能力退化的病患回復其肌肉的能力。常見之肌力訓練機器只允許單一平面運動但其訓練到的肌肉有限,反觀具有多自由度的自由重量運動(如啞鈴運動)則對整體肌肉強度的改善較為均勻。本文提出的設計在肩膀關節部份可提供三個自由度的運動且允許手肘關節一個自由度的運動,分別可作肩膀內旋-外旋(internal-external)、外展-內縮(abduction-adduction)與屈曲-伸展(flexion-extension)、再加上手肘屈曲-伸展運動。本文藉由建構一個自由重量運動之模型而得到在運動過程中人體上肢關節所受到的力矩值作為此設計的目標力矩值。此訓練機則是藉由三條彈簧的彈力來提供運動所需的阻力,使用者利用此訓練機進行運動時其關節所受到的力矩值必須相等於自由重量運動,進而達到相同的訓練效果。相較於自由重量運動是透過一個外加荷重提供運動所需之阻力,此設計之阻力值的增加則是藉由手動調整其彈簧的接點位置來達成,且其調整量與外加荷重呈現線性關係,可減少在啞鈴運動中高阻力時因過大的慣性力而導致關節過度伸展。本文提出之訓練機可模擬自由重量運動裡的啞鈴彎舉、前舉、側舉以及頭頂三頭肌延伸運動藉以訓練手臂上二頭肌、三頭肌、三角肌等手臂主要作用肌群,且藉由訓練機的幫助使手臂在運動過程中維持其正確的運動姿勢。同時,藉由等速肌力量測儀(isokinetic dynamometer)進行實驗量測實際自由重量運動時人體關節受到的力矩值,並與軟體模擬的結果相比,證實此設計的可行性並進行具體化設計。 Highly automated equipments and modern city life style lead to the diminishing opportunities for muscle using, however, the comfortable life is not always good for human health, and appropriate muscle training can not only enhance muscular strength and endurance but improve the health and fitness. Different kinds of ideas have been proposed for muscle training by exercise machines, which control direction of resistance for safety sake but merely isolate specific muscle groups to be trained. Compared with machines, free-weight exercise is a whole-body training in which human limb can move on different planes to train more muscle groups. In this study, an upper limb exoskeleton design is proposed for free-weight exercise to strengthen the principal muscles of upper limb and shoulder. The upper limb exoskeleton is consisted with 3-DOF shoulder joint and 1-DOF elbow joint. The joint torques of shoulder and elbow joints with the upper limb exoskeleton have to be equal to the objective joint torques that obtained from a model of free-weight exercise. The principal muscles of human arm and shoulder are training by dumbbell lateral raise, dumbbell frontal raise, dumbbell curl motion, and overhead triceps extension motion. Results of experiments which use isokinetic dynamometer to measure joint torques of male and female adult for shoulder abduction-adduction, flexion-extension, and elbow flexion-extension exercise prove the design is feasible. According to the results of preliminary design evaluation, this study provides the embodiment design of the upper limb exoskeleton. |
