The effect of ambient temperature on infrared thermographic images of joints in the distal forelimbs of healthy racehorses.

Abstract: The aim of the study was to describe the dependence on ambient temperature of distal joint temperature at the forelimbs of racehorses. The study also investigated the influence of differing ambient temperatures on the temperature difference between joints: this was measured ipsilaterally (i.e. between the carpal and fetlock joints along each forelimb) and contralaterally (i.e. between the same joints of the left and right forelimbs). Sixty-four healthy racehorses were monitored over 10 months. At each session, three thermographic images were taken of the dorsal, lateral and medial aspects of the distal forelimbs. Temperature measurements were made from regions of interest (ROIs) covering the carpal and fetlock joints. There was a strong correlation between ambient temperature and absolute joint temperature at all ROIs. The study also observed a moderate correlation between ambient temperature and the ipsilateral temperature differences between joints when measured from the medial and lateral aspects. No significant correlation was noted when measured dorsally. The mean contralateral temperature differences between joints were all close to 0°C. The data support previous reports that the temperature distribution between the forelimbs of the healthy equine is generally symmetric, although some horses differ markedly from the average findings.

The research paper explores how ambient temperature influences the thermographic images of joint temperature in horse’s forelimbs. The study examined both a direct comparison of joint temperatures and the temperature differences between various joints on the same and opposing sides.

Study Subjects and Methodology

  • The study involved 64 healthy racehorses monitored over a 10-month period.
  • In each session, three thermographic images were taken of the forelimbs focusing on the dorsal (back), lateral (side), and medial (middle) areas of the forelimbs.
  • The temperature measurements were taken from specified areas covering the carpal (wrist) and fetlock (ankle) joints, referred to as Regions of Interest (ROIs).

Role of Ambient Temperature

  • A strong correlation was found between the ambient temperature and the absolute joint temperature at all ROIs under investigation.
  • The researchers observed that changing ambient temperature moderately affected the temperature differences between the joints when measured from the side and middle aspects.
  • However, no significant changes were identified when the temperature differences were measured from the back aspect.

Symmetry in Distribution of Joint Temperatures

  • The study also looked at the temperature differences between the same joints of the left and right front legs of the horses. The average temperature difference was found to be nearly 0°C, indicating that the joint temperature distribution in horses’ limbs is generally symmetric.
  • This observation provides support to previous similar studies.

Individual Variations

  • Despite the general findings, the study noted that some horses exhibited markedly different temperatures in their limbs from the average findings, suggesting individual variations among horses.

In conclusion, the study sheds light on important considerations for thermographic imaging in veterinary medicine, particularly in relation to the effect of ambient temperature and the individual variations among horses.
