Learning effects during balance analysis on a modified posturomed-platform in healthy dogs

Area of Science:

• Veterinary medicine
• Animal biomechanics
• Balance assessment

Background:

• Posturographic balance assessments are increasingly utilized in veterinary diagnostics.
• Potential learning effects in canine posturography have not been previously studied.
• This research addresses the gap in understanding learning effects during canine balance evaluations.

Purpose of the Study:

• To investigate learning effects in static, slow-dynamic, and fast-dynamic posturography in healthy dogs.
• To determine if repeated exposure to posturographic assessments influences balance parameters.
• To provide insights for optimizing canine balance evaluation protocols.

Main Methods:

• Twenty healthy adult dogs underwent static, slow-dynamic, and fast-dynamic posturography using a modified pressure-sensitive platform.
• Center of Pressure (COP) parameters (path length, ellipse area, average velocity) were analyzed over three repeated trials spanning three weeks.
• Statistical analysis employed generalized linear or robust linear mixed-effects models to assess changes in COP parameters over time.

Main Results:

• No significant learning effects were found for static posturography across all measured COP parameters.
• Significant decreases in COP parameters were observed between the first and second trials under slow-dynamic conditions, with stability thereafter.
• All COP parameters significantly decreased over time under fast-dynamic conditions, indicating a training effect.

Conclusions:

• Static posturography in healthy dogs does not appear to be influenced by learning effects.
• Training effects are evident in both slow- and fast-dynamic posturography, suggesting that repeated trials can alter balance performance.
• These findings highlight the importance of considering training effects when interpreting dynamic posturographic data in canine evaluations.
