Description
Summary:碩士 === 國立成功大學 === 醫學工程研究所 === 88 === "Manual Materials Handling" (M.M.H.) included lifting, carrying, pushing, pulling, lowering and holding. It has been a topic of interest in many fields of research, particularly manual lifting. The primary reason for this interest is the devastating cost and human suffering caused by the severity of M.M.H.-related injuries. The lifting tasks are necessary in our active daily living. One potential hazard in lifting is the related musculo-skeletal injury of upper extremity, especially the wrist. Hence a number of recent studies sought to give recommendations for handles or containers to aid in manual lifting tasks. It is happened to reduce injury efficiently at the every joint of the upper extremity . The purpose of this study was to establish the 3-D kinematic and kinetic models of upper limbs. By imaged based motion analysis system, the movement pattern, the force and moment of the shoulder, elbow and wrist joint of eight right-handed male subjects during nine different types box lifting were collected and analyzed. One handle angle rotates about the vertical axis of the lifting box, and another rotates about the horizontal axis of the lifting box. By using the platform force plate on the ground, the ground reaction force all over these different types lifting was also collected and analyzed. The handle angles rotating the vertical axis of the lifting box are more singular than the handle angles rotating the horizontal axis for the biomechanical effect of upper extremity.
