[Thermography findings in the hands in relation to the age of the examined individual].

The authors compared thermographic findings of hands in two groups of apprentices (average age 15 and 16 years) with a group of students (average age 21 years) and a group of young workers (average age 29 years). There was a highly significant difference in the number of cold hands before and after vibration test in the apprentices and adults (29 years). The authors arrive at the conclusion that 1) thermoregulation reaches its final shape only after 20 years of age, 2) in the apprensitive thermographic finding must be verified by regular thermographic control examinations.
