Learning Confounds Algometric Assessment of Mechanical Thresholds in Normal Dogs
Tóm tắt
To perform algometric readings in normal dogs in a design that would assess possible confounding factors.
Prospective study.
Skeletally mature spayed female, intact male and castrated male retriever or retriever mix dogs without orthopedic or neurologic disease (n = 19).
Twelve common surgical sites were selected for algometric pressure testing. Threshold response was defined as a conscious recognition of the stimulus, and recorded in Newtons. Sites were tested in the same order, and the testing sequence repeated 3 times on each side of the dog. Dogs were tested in the morning and evening of the same day and was repeated 10–14 days later, allowing 4 separate data collections for each dog.
Data were analyzed using ANOVA or ANCOVA. When all the data were included in the analysis, dog (
These results suggest that learning occurred over repeated collection time points, with dogs anticipating the stimulus and reacting at lower thresholds.
