Measuring the range of motion (ROM) of the wrist is an important physical examination conducted in the Department of Hand Surgery for the purpose of evaluation, diagnosis, prognosis, and treatment of patients. The most common method for performing this task is by using a universal goniometer.
This study was performed using 52 healthy participants to compare wrist ROM measurement using a universal goniometer and the iPhone 4 Gyroscope application. Participants did not have previous wrist illnesses and their measured values for wrist motion were compared in each direction.
Normal values for wrist ROM are 73 degrees of flexion, 71 degrees of extension, 19 degrees of radial deviation, 33 degrees of ulnar deviation, 140 degrees of supination, and 60 degrees of pronation.The average measurement values obtained using the goniometer were 74.2 (5.1) degrees for flexion, 71.1 (4.9) degrees for extension, 19.7 (3.0) degrees for radial deviation, 34.0 (3.7) degrees for ulnar deviation, 140.8 (5.6) degrees for supination, and 61.1 (4.7) degrees for pronation. The average measurement values obtained using the iPhone 4 Gyroscope application were 73.7 (5.5) degrees for flexion, 70.8 (5.1) degrees for extension, 19.5 (3.0) degrees for radial deviation, 33.7 (3.9) degrees for ulnar deviation, 140.4 (5.7) degrees for supination, and 60.8 (4.9) degrees for pronation. The differences between the measurement values by the Gyroscope application and average value were 0.7 degrees for flexion, -0.2 degrees for extension, 0.5 degrees for radial deviation, 0.7 degrees for ulnar deviation, 0.4 degrees for supination, and 0.8 degrees for pronation. The differences in average value were not statistically significant.
The authors introduced a new method of measuring the range of wrist motion using the iPhone 4 Gyroscope application that is simpler to use and can be performed by the patient outside a clinical setting.
测量腕关节活动范围（ROM）是手外科进行的一项重要体格检查，用于患者的评估、诊断、预后和治疗。执行此任务最常用的方法是使用通用测角计。
本研究使用52名健康参与者，比较使用通用测角计和iPhone 4陀螺仪应用程序测量腕关节ROM的情况。参与者既往无腕部疾病，并对其每个方向的腕关节活动测量值进行比较。
腕关节ROM的正常值为屈曲73度、伸展71度、桡侧偏斜19度、尺侧偏斜33度、旋后140度和旋前60度。使用测角计获得的平均测量值为屈曲74.2（5.1）度、伸展71.1（4.9）度、桡侧偏斜19.7（3.0）度、尺侧偏斜34.0（3.7）度、旋后140.8（5.6）度和旋前61.1（4.7）度。使用iPhone 4陀螺仪应用程序获得的平均测量值为屈曲73.7（5.5）度、伸展70.8（5.1）度、桡侧偏斜19.5（3.0）度、尺侧偏斜33.7（3.9）度、旋后140.4（5.7）度和旋前60.8（4.9）度。陀螺仪应用程序测量值与平均值之间的差异为屈曲0.7度、伸展 -0.2度、桡侧偏斜0.5度、尺侧偏斜0.7度、旋后0.4度和旋前0.8度。平均值差异无统计学意义。
作者介绍了一种使用iPhone 4陀螺仪应用程序测量腕关节活动范围的新方法，该方法使用更简便，患者可在临床环境外自行操作。
