Sensory-Discriminative Three-Dimensional Body Pain Mobile App Measures Versus Traditional Pain Measurement With a Visual Analog Scale: Validation Study

Abstract: Background To quantify pain severity in patients and the efficacy treatments, researchers and clinicians apply tools such as the traditional visual analog scale (VAS) that leads to inaccurate interpretation of the main sensory pain. Objective This study aimed to validate the pain measurements of a neuroscience-based 3D body pain mobile app called GeoPain. Methods Patients with temporomandibular disorder (TMD… Show more

“… 25 , 35 The GeoPain is a 3D-body navigation system to record objective sensory-discriminative information of pain in real-time, which is quantifiable, reproducible, and validated. 36 In addition to pain area and average pain intensity by body region (eg, head), it produces a Pain Area and Intensity Number Summation (PAINS) score by multiplying the pain area (from the 220 cells) by their numerical headache intensity (mild=1 (visual analog scale [VAS]: 1–3), moderate=2 (VAS: 4–7), severe=3 (VAS: 8–10)). We divided this individual PAINS score by 660 (220 * 3) to calculate a percentage estimate of the ictal pain severity.…”

“…Patient-reported pain intensity is commonly measured with the single VAS. However, VAS alone may not capture all features of pain [ 69 , 70 ] and may be not sufficient to assess pain in patients with axSpA [ 71 ]. Finally, additional research is required to determine whether factors other than pain may influence gait in patients with axSpA.…”

“…Quanto ao método utilizado nos estudos, percebe-se prevalência do processo de validação por comparação com método previamente validado, com diferentes formas de análises, que se mostrou eficaz, evidenciando a usabilidade e qualidade dessas tecnologias (Bastawrous et al, 2015;Kaciroti et al, 2020;Purves et al, 2019), de modo que, ao comparar uma mHealth em contraste a outros métodos, mostrou-se a preferência pelo uso da tecnologia pela população (Ahmed et al, 2017). Destarte, evidencia-se também o processo de validação por meio da Escala de Usabilidade do Sistema que traz protagonismo ao usuário no processo de validação de modo relevante, como evidenciado (Seeber et al, 2017).…”
