One hundred normal upper extremities in 50 adults were sequentially studied in a Bledsoe brace, which limited elbow motion. The amount of flexion and extension of the elbow was serially limited by 15 degree increments. At each setting, the subjects were asked to perform 12 activities of daily living. The percentage of subjects who completed each task with the specified range of motion was determined. Overall, 49 of the subjects performed all of the tasks with extension limited at 75 degrees and flexion limited at 120 degrees. By isolating the allowable range of motion of the elbow and allowing for compensatory motions and strategies of the normal adjacent joints, the functional elbow range of motion is established as 75 degrees-120 degrees flexion. Thus, the functional status of a patient with a specific elbow range of motion can be predicted more accurately.
对50名成年人的100条正常上肢依次使用限制肘部活动的布莱索支具进行研究。肘部屈伸的幅度以15度的增量依次受限。在每个设置下，要求受试者进行12项日常生活活动。确定了在指定活动范围内完成每项任务的受试者百分比。总体而言，49名受试者在伸展受限75度和屈曲受限120度的情况下完成了所有任务。通过分离肘部允许的活动范围，并考虑正常相邻关节的代偿性运动和策略，确定功能性肘部活动范围为屈曲75度至120度。因此，可以更准确地预测具有特定肘部活动范围的患者的功能状态。
