To investigate whether exposure to pulsed high-frequency electromagnetic field (pulsed EMF) emitted by a mobile phone has short-term effects on the visuo-motor choice reaction time (RT) and movement time (MT).
A double blind, counterbalanced crossover design was employed. In 16 normal subjects, we studied the performance of a visuo-motor precued choice reaction time task (PCRT) before and after exposure to EMF emitted by a mobile phone for 30 minutes or sham exposure.
The RTs and MTs under different conditions of precue information were not affected by exposure to pulsed EMF emitted by a mobile phone or by sham phone use.
Thirty minutes of mobile phone use has no significant short-term effect on the cortical visuo-motor processing as studied by the present PCRT task.
This is the first study to investigate visuo-motor behavior in relation to mobile phone exposure. No significant effect of mobile phone use was demonstrated on the performance of the visuo-motor reaction time task.
研究暴露于手机发出的脉冲高频电磁场（脉冲电磁场）是否对视动选择反应时间（RT）和运动时间（MT）有短期影响。
采用双盲、平衡交叉设计。在16名正常受试者中，我们研究了在暴露于手机发出的电磁场30分钟或假暴露前后，视动预提示选择反应时间任务（PCRT）的表现。
不同预提示信息条件下的RT和MT不受暴露于手机发出的脉冲电磁场或假使用手机的影响。
如本PCRT任务所研究，使用手机30分钟对皮质视动加工没有显著的短期影响。
这是第一项研究与手机暴露相关的视动行为的研究。未证明使用手机对视动反应时间任务的表现有显著影响。
