Safety conditions in dynamic IT examinations of rheumatoid arthritis lesions
Journal Title: Aparatura Badawcza i Dydaktycza - Year 2017, Vol 22, Issue 3
Abstract
Purpose of the article: Human skin temperature distribution is a source of clinically relevant informa- tion about tissue pathological process and can be observed with the use of non-contact ad non-invasive measuring technique named infrared thermography (IT). The aim of the study is to establish dynamic IT measurement safety conditions in RA examination in order to prepare the refined study protocol which provides for extracting the most reliable diagnostic thermal data. Experimental part: Thirty participants (20% of males) with diagnosed RA were included in this study. The protocol consisted in registration of thermal recovery processes after immersing left and right foot separately in ice water of less than 0 Celsius degrees. Cooling procedure included immersing left and right foot separately in ice water for 5 seconds. Separate recordings of left and right foot temperature changes were performed for 3 minute periods. The following joint temperatures were measured: ankle joint and 5 metatarsophalangeal joints. Conclusions: Difference between the moment right after immersion and the moment after 3-minute recovery appeared to be the lowest in two different patients’ ankle joints. These results suggest that the slowest rewarming rate occurs in the area of ankle joint.
