History
The patient had a history of stifle lameness.
Physiological Screen with Digital Thermal Imaging
The patient was acclimated to room temperature, was not handled during acclimation, and remained calm during image capture. Digital thermal images were captured with a Digatherm IR camera.
Interpretation of the Thermal Images
The initial image (Fig. 1) shows generalized areas of hypothermic activity and scattered small areas of hyperthermia. The pattern is consistent with reduced circulation secondary to nerve inflammation from chronic stifle disease.
Interpretation of the Follow-up Thermal Images
Fifteen minutes after aquapuncture follow-up thermal images were captured. The left lateral image (Fig 2.) showed a significant increase in the thermal gradient in the left rear leg, correlating with re-establishment of circulation.
