Abstract

The spinal reflexes are a part of the neurological examination that aids in lesion localization. There are many factors that could influence the reflex response and its grading, and the reliability of the reflexes is still being discovered. This study aims to investigate the effect of age and weight on the intensity of the thoracic limb reflexes and to grade the thoracic limb reflex and to conduct inter-observer agreement on the thoracic limb reflex response in healthy dogs. This study used dogs with 30 dogs consisting of 25 males and 5 females, various dog breeds with mean age (7.9 ± 3.98) years and a mean weight (20.86 ± 7.98) kg. The dogs were categorized into 1 or 2 groups based on age: group 1, <7 years; and group 2, >7 years and weight into group 1, <15kg; and group 2, >15kg. All dogs were healthy at the time of examination. Triceps reflex, extensor carpi radialis reflex and withdrawal reflex were elicited on both limbs by a hammer reflex while the dog was in lateral recumbency while the processed is video tapped. The reflex presence was scored by three different groups of observers depending on the level of expertise (one neurologist, one veterinary surgeon, and two veterinary students). Fleiss’ Kappa Correlation were applied for analysis of inter-observer agreement on the reflexes. Withdrawal reflex being the easiest reflex to elicit with overall Kappa value (0.20) which was the highest (fair agreement) scored by the observers. Triceps and extensor carpi radialis reflex had value of (0.06) and (0.04) which was of poor agreement. Spearman’s rank test was used to show that age and weight have no correlation with the reflexes.
