METHODS: Static TPD thresholds of 67 healthy young adults aged 18-35 years were assessed. Eight skin areas in the face and upper extremity on the dominant side were assessed using a \"method of limits\" approach with an aesthesiometer. Differences between genders were examined with the Mann-Whitney U test. The Spearman correlation analysis investigated the relationship between age and TPD measurements.
RESULTS: TPD values ranged between 4.66 and 19.16 mm and 1.33-68.66 mm in the face and upper extremity, respectively, in the participants with a mean age of 23.83 ± 4.66 years. Fingertips and the area over the lateral mandibula showed the greatest sensitivity. The threshold values of TPD showed both interindividual and intraindividual variability. There was no statistical difference in the TPD values according to gender in any of the measured areas, and there was no relationship between age and TPD test values.
CONCLUSIONS: The threshold values of TPD have clinical applicability in various diseases affecting the sensation of the upper extremity and/or face. These data may help the detection of early sensory loss.
方法:对67名年龄在18-35岁的健康年轻人的静态TPD阈值进行评估。使用“极限方法”方法和美学仪对优势侧的面部和上肢的八个皮肤区域进行了评估。使用Mann-WhitneyU检验检查了性别之间的差异。Spearman相关分析研究了年龄与TPD测量值之间的关系。
结果:面部和上肢的TPD值介于4.66和19.16mm和1.33-68.66mm之间,分别,在平均年龄为23.83±4.66岁的参与者中。指尖和下颌骨外侧区域显示出最大的敏感性。TPD的阈值显示了个体间和个体内的变异性。在任何测量区域中,根据性别的TPD值没有统计学差异,年龄与TPD测试值之间没有关系。
结论:TPD的阈值在影响上肢和/或面部感觉的各种疾病中具有临床适用性。这些数据可能有助于早期感觉丧失的检测。
