Posture disorder affects more and more people in every age and social group, causing a huge drop in energy (tiredness, depression) or even nerve compression. The early assessment allows introducing therapy that minimizes the influence on everyday life. In the presented approach authors focused on the analysis of thermal images. The research group consists of 101 people, but only 69 were selected for further analysis (24 in the pathological group and 44 described as normative). Appropriate clothing for women turns out to be a very important element of the protocol. Each patient was photographed 3 times by thermovision camera (before, immediately after and 10 min after exercises). Using a proprietary algorithm the patient’s body (back) was divided into 10 ROI. The cross-validation kNN classifier was used to divide the subject into appropriate categories – normative or pathological. On the basis of the temperature data, the matched-pair t-test shows the significant statistical difference before and after exercise for all ROI in both normative and pathological group. Classification result based on after exercise data is 72.1% in contrary to 57.4% obtained from data before exercise.
