To establish normative pronation and supination torque values in right-handed adults without evidence of upper-extremity dysfunction or impairment in the forearm positions of neutral, pronation, and supination.
Fifty-one normal right-handed participants ages 22 to 45 years were enrolled and tested in this study using a custom device that incorporated a torque cell and a grip system that produced a digital recording of the peak torque during maximal resisted pronation and supination in positions of neutral forearm rotation, 60 degrees pronation, and 60 degrees supination.
The greatest peak torque strength for both male and female participants was found during resisted pronation in the supinated position. The peak torque values averaged 11.9 +/- 3.7 N.m on the right side and 10.4 +/- 3.3 N.m on the left side for men, and 6.0 +/- 1.4 N.m on the right side and 5.0 +/- 1.2 N.m on the left side for women. The weakest torque strengths were resisted pronation in the pronated position and resisted supination in the supinated position.
Torque strength measurements are reliable and should be collected when treating patients with forearm dysfunction. Maximal torque follows the same pattern related to hand dominance as grip strength. Men generate average torque strengths that are approximately twice the magnitude of those generated by women.
在无上肢功能障碍或前臂无损伤的右利手成年人中，建立中立位、旋前位和旋后位时正常的旋前和旋后扭矩值。
本研究纳入了51名年龄在22至45岁之间的正常右利手参与者，并使用一种定制设备进行测试，该设备包含一个扭矩传感器和一个握力系统，可在中立位前臂旋转、60度旋前和60度旋后位进行最大抗阻旋前和旋后时对峰值扭矩进行数字记录。
男性和女性参与者在旋后位抗阻旋前时的峰值扭矩强度最大。男性右侧峰值扭矩值平均为11.9±3.7N·m，左侧为10.4±3.3N·m；女性右侧为6.0±1.4N·m，左侧为5.0±1.2N·m。最弱的扭矩强度是旋前位抗阻旋前和旋后位抗阻旋后。
扭矩强度测量是可靠的，在治疗前臂功能障碍患者时应进行测量。最大扭矩与握力一样，遵循与利手相关的相同模式。男性产生的平均扭矩强度约为女性的两倍。
