BACKGROUND
Reaction time (RT) is an indicator of neural activity, however, its variation due to visual (VRT), audio (ART) and tactile (TRT) in African medical students has not been investigated. The aim of the study was to determine relationships between VRT, ART and TRT amongst medical students in Uganda.
MATERIALS AND METHODS
This was a cross sectional study, the body mass index (BMI) and RT (i.e. VRT, ART and TRT) were determined using weighing scale with standiometer and the catch a ruler experiment respectively. A questionnaire was administered to collect information on participant's lifestyle patterns and analysis was done using SPSS Version 20.
RESULTS
The mean (± SEM) VRT, ART and TRT in the study were found to be 0.148 ± 0.002s, 0.141 ± 0.002s and 0.139 ± 0.003s respectively. A strong correlation between TRT and ART was found to exist in the youthful Ugandan medical student's population. Furthermore, significant differences in ART and VRT were observed with sex, although these were absent amongst preclinical and clinical students, showing the importance of sex in RT.
CONCLUSION
The low VRT and ART in Ugandan medical students is indicative of a healthy somatosensory connectivity, thus of academic importance.
背景
反应时间（RT）是神经活动的一个指标，然而，非洲医学生中视觉反应时间（VRT）、听觉反应时间（ART）和触觉反应时间（TRT）的变化尚未得到研究。本研究的目的是确定乌干达医学生中VRT、ART和TRT之间的关系。
材料与方法
这是一项横断面研究，分别使用带身高计的体重秤和抓尺子实验来测定体重指数（BMI）和反应时间（即VRT、ART和TRT）。通过问卷调查收集参与者生活方式模式的信息，并使用SPSS 20版进行分析。
结果
研究中VRT、ART和TRT的平均（±标准误）值分别为0.148±0.002秒、0.141±0.002秒和0.139±0.003秒。研究发现，在年轻的乌干达医学生群体中，TRT和ART之间存在很强的相关性。此外，观察到ART和VRT在性别上存在显著差异，尽管在临床前和临床学生中不存在这种差异，这表明性别在反应时间方面的重要性。
结论
乌干达医学生较低的VRT和ART表明其躯体感觉连接健康，因此具有学术意义。
