There has been a lack of detailed studies focusing on measuring pressure thresholds in the auricle and periauricular areas. This study aimed to investigate surface pressure sensitivity (SPS) in 320 healthy Chinese adults (aged 20–59), measuring Pressure Pain Threshold (PPT). Significant differences of PPTs observed between age groups and genders. PPT values varied across different measurement points and areas, showing correlations with age, height, weight, and BMI changes. Additionally, certain characteristics such as the ear lobe extension and external ear protrusion were associated with lower SPS in the measurement areas. The results and findings of this study pertain to the Chinese population and give an understanding of age-related trends, bilateral differences, and gender influences on SPS for the development of ear-related wearables.

摘要

There has been a lack of detailed studies focusing on measuring pressure thresholds in the auricle and periauricular areas. This study aimed to investigate surface pressure sensitivity (SPS) in 320 healthy Chinese adults (aged 20–59), measuring Pressure Pain Threshold (PPT). Significant differences of PPTs observed between age groups and genders. PPT values varied across different measurement points and areas, showing correlations with age, height, weight, and BMI changes. Additionally, certain characteristics such as the ear lobe extension and external ear protrusion were associated with lower SPS in the measurement areas. The results and findings of this study pertain to the Chinese population and give an understanding of age-related trends, bilateral differences, and gender influences on SPS for the development of ear-related wearables.
