BACKGROUND - Currently, infra red thermography was being widely used in diabetic foot diagnosis. It has been reported predict high risk for developing diabetic foot ulcers (DFU), distinguish presence neuropathy, determine presence complications, predict acute inflammation and latent inflammation, identify the presence of infection, biomechanics status of the foot. Nowadays, FLIR ONE™, a non-contact infra-red mobile thermography, which attaches to smart phone was available. However, its reliability and validity are not reported.

 

OBJECTIVE - The aims of this study were to evaluate the validity and reliability non contact infrared thermography in healthy adults

 

METHODS - Two healthy adults participate in this study. Participants acclimatisated at least 15 minutes in the supine position without socks and shoes with ambient room, temperature controlled at 26 0C and 60% for room humidity.  To maintain relative point-to-point measurement, hydrocolloid will be using a skin marker at dorsal site and plantar side both foot. A non-contact infra-red mobile thermography (FLIR ONE™) which attached to iPhone 5s (Apple Inc) compared with Raytek ST 60 as validity control.  Data collecting two times (baseline and 30 minutes). Validity between devices and reliability between observer were analyzed with Pearson correlation by using SPSS ver 16.

 

RESULTS - Validity between devices were correlated in baseline right dorsal (r = 0. 854, p = 0.001), (r = 0. 598, p = 0.010), baseline right plantar (r = 0. 707, p = 0.001), (r = - 0. 523, p = 0.026), left dorsal 30 minutes (r = 0. 552,  p = 0.017) and left plantar baseline (r = - 0. 566, p = 0.014). However, other observation areas were not significant (p< 0.05).  Regard to interobserver reliability, correlation were significant in right dorsal baseline (r = 0. 612, p = 0.007) and right plantar 30 minutes  (r = 0. 885, p = 0.001).

 

CONCLUSIONS - This finding indicates interpretation should be noted related to quantitative data of FLIR ONE™.
