The aim of this study is to analyze the effect of stress-induced cortisol increase on the sense of ankle proprioception.
Between April 2016 and May 2016, a total of 60 students (30 males, 30 females; mean age: 19.2±1.5 years; range, 19 to 20 years) from İnönü University, Faculty of Medicine, Department of Freshmen were included in the study. Separate measurements were made for the right and left ankle to make ankle proprioception measurements a month before the committee exam during their relaxed period using a device designed with digital inclinometer. The sense of ankle proprioception was measured at 10° dorsiflexion (DF), 11° plantar flexion (PF), and 25° PF angles with open eyes and closed eyes using active reproduction test. Salivary samples were taken for stress assessment and State Trait Anxiety Inventory-I (STAI-I) was conducted. The same tests were repeated on the day of committee exam.
Test results showed no statistically significant difference between the right and left ankle proprioception measurements of 10° DF, 11° PF, and 25° PF angles with open eyes (p>0.05). However, a statistically significant difference was found between the right and left ankle proprioception scores at the same angles with closed eyes (p<0.05). According to the Wilcoxon analysis conducted for the comparison of the relaxed and stressed periods of cortisol and STAI-I inventory, a statistically significant difference was found (p<0.05). The Spearman's Rho analysis showed no significant correlation between the right and left ankle proprioception scores and cortisol and STAI-I with open eyes, while there was a statistically significantly positive direction and low correlation between the same angles with closed eyes.
Our study results show that the increase in the stress-related cortisol is negative for the ankle proprioception sense.
本研究旨在分析应激诱导的皮质醇增加对踝关节本体感觉的影响。
2016年4月至2016年5月，来自伊诺努大学医学院大一新生系的60名学生（30名男性，30名女性；平均年龄：19.2±1.5岁；范围19至20岁）被纳入研究。在委员会考试前一个月的放松期，使用数字倾角仪设计的设备对左右踝关节进行单独测量，以进行踝关节本体感觉测量。使用主动再现测试，在睁眼和闭眼状态下，于10°背屈（DF）、11°跖屈（PF）和25°PF角度测量踝关节本体感觉。采集唾液样本进行应激评估，并进行状态特质焦虑量表-I（STAI-I）测试。在委员会考试当天重复相同测试。
测试结果显示，睁眼状态下10°DF、11°PF和25°PF角度的左右踝关节本体感觉测量之间无统计学显著差异（p>0.05）。然而，闭眼状态下相同角度的左右踝关节本体感觉评分之间存在统计学显著差异（p<0.05）。根据对皮质醇和STAI-I量表放松期和应激期进行比较的Wilcoxon分析，发现存在统计学显著差异（p<0.05）。Spearman's Rho分析显示，睁眼时左右踝关节本体感觉评分与皮质醇和STAI-I之间无显著相关性，而闭眼时相同角度之间存在统计学显著的正相关且相关性较低。
我们的研究结果表明，应激相关皮质醇的增加对踝关节本体感觉有负面影响。
