Popis:	Mechanical behavior is difficult to monitor in experimental environments, usually because of geometric or technology implementation limitations. Nevertheless, thermography has been shown to overcome these issues.The aim of this study was to evaluate four types of assemblies between a Jaipur foot and a polyethylene tube using infrared thermography in order to find the best mechanical configuration in terms of thermal behavior.Mechanical testing.An infrared camera captured short videos every 5 min over 10 h in six different positions (three in the back and three in front of the Jaipur foot) around a prosthesis subjected to repetitive stresses (axial force 980 N) simulating kinematic variables like joint angles. We established a region of interest around the foot-ankle assemblies and calculated maximum temperatures and thermographic indices.In this study, the best foot-ankle assembly used epoxy adhesive because it presented the lowest temperature in the six positions and the lowest thermal index.Thermographic techniques can be used to study mechanical behaviors in complex experimental situations.
