Abstract：
UNASSIGNED: This study aims to measure the two-point discrimination (TPD) values of the upper extremities of healthy young Turkish individuals.
UNASSIGNED: Between March 2016 and June 2016, a total of 60 healthy students (31 males, 29 females; mean age: 22.0±1.7 years; range, 19 to 27 years) were included. Eleven grand upper limb parts which take innervation from the brachial plexus were measured with an esthesiometer.
UNASSIGNED: The values at the dominant sides were statistically significantly greater than the non-dominant sides at those areas: upper lateral arm (p=0.001), lower lateral arm (p=0.001), mid-posterior arm (p=0.001), mid-lateral forearm (p=0.001), mid-posterior forearm (p=0.012), skin over the first dorsal interossei muscle (p=0.031), and palmar surface of distal phalanx of the thumb (p=0.045). Both dominant and non-dominant lower lateral arm TPD measurement results increased in males compared to females, indicating a statistically significant difference (p=0.005 and p=0.011, respectively). Also, dominant and non-dominant mid-posterior arm measurement scores were found to statistically significantly increase in males compared to females (p=0.019 and p=0.040, respectively).
UNASSIGNED: Our study results show that laterality, with lower values on the non-dominant side, but not the sex, has an effect on TPD. The findings of this study may be useful in establishing the normative data for TPD in the upper extremity parts of healthy young Turkish individuals.

摘要：
■本研究旨在测量健康的年轻土耳其个体上肢的两点辨别（TPD）值。
■在2016年3月至2016年6月之间，共有60名健康学生（31名男性，29名女性；平均年龄：22.0±1.7岁；范围，包括19至27年）。用美感仪测量了从臂丛神经支配的11个上肢大部位。
■在这些区域，优势侧的值在统计学上显着大于非优势侧的值：上侧臂（p=0.001），下侧臂（p=0.001），中后臂（p=0.001），前臂中外侧（p=0.001），前臂中后（p=0.012），第一背侧骨间肌的皮肤（p=0.031），拇指远端指骨的掌面（p=0.045）。与女性相比，男性的显性和非显性下侧臂TPD测量结果均增加，表明统计学上的显着差异（分别为p=0.005和p=0.011）。此外，与女性相比，男性的显性和非显性中臂后臂测量得分在统计学上显着增加（分别为p=0.019和p=0.040）。
■我们的研究结果表明，在非优势侧具有较低的值，但不是性,对TPD有影响.这项研究的结果可能有助于建立健康的土耳其年轻人上肢TPD的规范数据。
