BACKGROUND
Polygraph or lie detection test has been used since early 90s as an effective method in forensic investigations. However, polygraph does not have a stand-alone value in legal forums. Any novel scientific addition can strengthen the credibility of the polygraph.
AIM
This study aims to determine whether the deception could be detected with the help of polygraph where electromyography (EMG) readings of the masseter muscle, along with electrocardiography and galvanic skin response, were considered.
MATERIALS AND METHODS
The study was conducted on 14 participants in a well-established research setup. Card Test and Affirmative Test were performed on participants and the readings were critically analyzed.
RESULTS
In both the tests performed, the deceptions were easily detected once and rarely detected twice. In some cases, the deceptions were undetected.
CONCLUSION
The result indicated with minimal credence that EMG helps in detecting deception. The accuracy of detection however can be confirmed only after an extensive research.
背景
自20世纪90年代初以来，测谎仪或说谎检测测试一直被用作法医调查中的一种有效方法。然而，测谎仪在法律论坛中并没有独立的价值。任何新的科学补充都可以增强测谎仪的可信度。
目的
本研究旨在确定在将咬肌肌电图（EMG）读数与心电图和皮肤电反应一并考虑的情况下，是否可以借助测谎仪检测出欺骗行为。
材料与方法
该研究在一个成熟的研究机构中对14名参与者进行。对参与者进行了卡片测试和肯定性测试，并对读数进行了严格分析。
结果
在进行的两项测试中，欺骗行为很容易被检测出一次，很少被检测出两次。在某些情况下，欺骗行为未被检测到。
结论
结果以极小的可信度表明，肌电图有助于检测欺骗行为。然而，只有经过广泛研究才能确认检测的准确性。
