Abstract : Pain threshold is the lowest intensity at which a specific stimulus is perceived as painful; it’s relatively constant across subjects for a given stimulus. For example, most subjects will define a thermal stimulus as painful when it reaches about 50° C. Similarly, mechanical pressure produces pain (Pressure Pain Threshold/PPT) at approximately the same pressure across subjects. Pain threshold because it relates to sensitivity to pressure is measured with a pressure algometer. The most objective of this study was to research the correlation between Faces Pain Scale-Revised (FPS-R) and the pressure algometer as assessment of pain threshold in normal healthy children. 170 normal healthy children of both sexes with age ranged from 4-10 years old were allocated into three groups: (4 < 6 years old) group (1), (6 < 8 years old) group (2) and (8-10 years old) group (3) who been selected from several nurseries and schools. The pain threshold was assessed by both the Digital Pressure Algometer (Egyptian Digital Algometer, Patent No.258 for 2017) and FPS-R on dominant upper limb and lower limb. The results showed that the correlation between FPS-R and PPT of the study group was a weak negative significant correlation in both upper limb and lower limb. The correlation between FPS-R and PPT of children in group (1) was a weak positive non-significant correlation in both upper and lower limbs. The correlation between FPS-R and PPT of children in group (2) was a weak positive non-significant correlation in both upper and lower limbs. The correlation between FPS-R and PPT of children in group (3) was a weak positive non-significant correlation in both upper and lower limbs. We concluded that there is no correlation between the pressure algometer and FPS-R in assessing the pain threshold.
