  • Abstract:
  • Gait analysis has emerged as a valuable biometric tool in forensic science, particularly in cases where traditional identification methods such as DNA profiling fail to distinguish between individuals. This study examines the effectiveness of gait pattern analysis in differentiating identical (monozygotic) twins using two-dimensional (2D) footprint measurements. Identical twins share nearly identical genetic material, making conventional forensic identification methods inadequate in certain scenarios. Therefore, this research explores whether measurable gait parameters—such as step length, stride length, step width, and foot angle—can provide reliable distinguishing features. The study involved collecting 2D footprint samples from identical twins under controlled conditions using ink-based walking techniques. The collected data were analysed using statistical tools, including paired t-tests, to determine the presence of significant differences between twin pairs. The findings revealed minor variations in gait parameters; however, these differences were not statistically significant (p > 0.05), indicating a high level of similarity in walking patterns among identical twins. The study concludes that while gait analysis demonstrates potential as a supportive forensic tool, it cannot serve as a standalone method for differentiating identical twins. Further advancements in analytical techniques and integration with other biometric methods are essential to enhance forensic identification accuracy.
