This study was designed to quantify the range of upper limb joint motion required during the performance of a specific type of functional activity. Ten able-bodied men were studied as they performed three feeding tasks--eating with a spoon, eating with a fork, and drinking from a handled cup. Three shoulder joint rotations, one elbow joint rotation, one forearm joint rotation, and three wrist joint rotations were quantified simultaneously using a three-dimensional measurement system. It was found that the required ranges of motion for the feeding tasks were 5 degrees to 45 degrees shoulder flexion, 5 degrees to 35 degrees shoulder abduction, 5 degrees to 25 degrees shoulder internal rotation, 70 degrees to 130 degrees elbow flexion, from 40 degrees forearm pronation to 60 degrees forearm supination, from 10 degrees wrist flexion to 25 degrees wrist extension, and from 20 degrees wrist ulnar deviation to 5 degrees wrist radial deviation. Wrist rotation was also measured, but it was found to be negligible.
本研究旨在量化进行特定类型功能活动时所需的上肢关节活动范围。对10名身体健全的男性进行了研究，他们执行了三项进食任务——用勺子进食、用叉子进食以及从有把手的杯子喝水。使用三维测量系统同时对三个肩关节旋转、一个肘关节旋转、一个前臂关节旋转和三个腕关节旋转进行了量化。结果发现，进食任务所需的活动范围为肩关节前屈5度至45度、外展5度至35度、内旋5度至25度，肘关节屈曲70度至130度，前臂旋前40度至旋后60度，腕关节屈曲10度至伸展25度，以及尺偏20度至桡偏5度。还测量了腕关节旋转，但发现其可忽略不计。
