A Study of the Distribution of Pressure Pain Thresholds for the Human Head

Head constitutes a vital component of the human body. Therefore, in activities such as cycling, aviation, and other driving operations, ensuring adequate protection for the head through helmet usage becomes paramount. In this study, the area covered by the helmet is divided into six regions, and the high-density head pressure pain thresholds (PPT) are obtained through 128 measurement points. As a result, the PPT in the frontal pole and temporal regions gains the lowest index while that in the central gains the highest. Additionally, the PPT is slightly higher in females than that in males, but there was no statistical difference. PPT is negatively related to the body fat ratio (BFR), while the primary correlation area in both males and females are the parietal and occipital regions. Therefore, the results can provide a better understanding of the pressure pain sensitivity of the human head and offer robust data support for the design and optimization of ergonomic helmet pressure distribution in the future.
