OBJECTIVE: To check using the infrared thermography if the skin has a temperature reduction in the lumbar region induced by chiropractic adjustment. METHODS: Research with 22 men with complaints of low back pain. They were splitted into two groups: (a) the intervention group consisted of 14 individuals who received lumbar spinal manipulation between the thermography analysis and (b) the control group with eight individuals was submitted to the thermography analysis. The comparative analysis of the results was performed using graphs and the Kolmogorov-Smirnov and T-Student tests. RESULTS: The data presented in the control group proved an average decrease in the lumbar temperature of (0.6°C), and that the temperature average pre interval of 20 minutes was 30.5°C and the post temperature of 29.9ºC. The temperature average value of the pre chiropractic adjust was 30.7ºC and the post was 30.1°C. The statistic comparison values showed a significant difference between the average (p=0.009). CONCLUSIONS: The articular therapy adjustment proved effective, presenting a significant decrease of temperature in the lower back of the individuals at the intervention group when compared to the control group. The thermography proved itself important in the analysis of the results.
