Raynaud’s Phenomenon Differentiating After Cold Stress Using Thermal Parameters from Fingers

摘要: The objective of this study was to determine parameters that better describe thermal models separate people who present Raynaud’s phenomenon (RP) from those do not. A descriptive exploratory conducted with 284 participants (primary RP = 14; secondary 12; without diagnosis 258) aged between 18 and 60 years, in the city Curitiba, Brazil. camera (Fluke Ti400) used photograph skin temperature following a cold stress protocol. hands were then immersed up carpal level container water at 10 °C for s. Images both six different moments taken: (a) pre-stress cold; (b) immediately after related every 5 min, until 20 min post-immersion. In order find best identify primary Raynaud, several features based on dissimilarities fingers evaluated. Our results show dorsal-distal difference (DDD) is well-known individuals not have RP. However, Raynaud mix up, so no pattern can be possibly distinguished. addition, result classification achieved using maximum absolute 15 reaching an accuracy 80.56% ± 17.35%.
