Fatigue is one of the factors causing disturbance in proprioception which can be manifested in two ways: general and local. Due to the important role of cervical proprioception on body stability and posture, research on the effects of general fatigue on proprioception helps to better understand its mechanism and to improve the strategies to prevent injury. Therefore, the aim of this study was to identify the effects of general fatigue on head and neck proprioception in young healthy adults.
This clinical study was done by implementing pre- and post-test measurements in 112 young healthy subjects aged between 18-30 years and able to walk at a speed of 10Km for 5 minutes. They were randomly divided into an experimental and control group. The patients in the control (not exposed to a general fatigue task) and experimental (exposed to a general fatigue task) groups were matched for age, height and weight. In the first step, the zero absolute reposition angle of the head and neck was measured in all participants. Then the subjects in the experimental group did a five-minute run on the treadmill to achieve the level of general fatigue, following which the head and neck reproduction angle was measured in all subjects for the second time.
There was a statistical significant difference between pre- and post-test absolute angular error in the experimental group; however, there was no noticeable difference between the pre- and post-test data in the control group.
疲劳是导致本体感觉紊乱的因素之一，可通过两种方式表现出来：全身性和局部性。由于颈部本体感觉对身体稳定性和姿势具有重要作用，研究全身性疲劳对本体感觉的影响有助于更好地理解其机制，并改进预防损伤的策略。因此，本研究的目的是确定全身性疲劳对年轻健康成年人头颈部本体感觉的影响。
本临床研究通过对112名年龄在18至30岁之间、能够以每小时10公里的速度行走5分钟的年轻健康受试者进行测试前和测试后测量来完成。他们被随机分为实验组和对照组。对照组（未接受全身性疲劳任务）和实验组（接受全身性疲劳任务）的患者在年龄、身高和体重方面进行了匹配。第一步，测量所有参与者头颈部的零绝对复位角度。然后，实验组的受试者在跑步机上进行五分钟跑步以达到全身性疲劳水平，之后再次测量所有受试者的头颈部再现角度。
实验组测试前和测试后绝对角度误差之间存在统计学显著差异；然而，对照组测试前和测试后的数据之间没有明显差异。
