Audio-Based Characterization of Gait Parameters in Mangalarga Marchador, Campolina, and Piquira Horses Using Deep Learning
This study presents an innovative AI model leveraging Long Short-Term Memory (LSTM) neural networks to objectively quantify equine gait parameters from acoustic data. Achieving a high predictive accuracy (R² = 0.98), the model translates subjective assessments into precise metrics for hoof-ground contact intervals and dissociation. Our findings lay the groundwork for a low-cost, non-invasive method that can significantly advance performance evaluation, selection, and digital phenotyping in equine breeding programs.

High-Fidelity Gait Interval Prediction
Our AI model, utilizing a Long Short-Term Memory (LSTM) neural network, achieved remarkable accuracy in predicting the time intervals between successive hoof-ground contacts. With an R² score of 0.98 and a Mean Absolute Error (MAE) of just 0.0071, this demonstrates a robust and reliable foundation for objective gait analysis in equine breeding programs. This precision allows for the quantification of previously subjective assessments, offering a new standard for performance evaluation and genetic improvement.
Unveiling Subtle Dissociation Dynamics
The analysis of dissociation percentage revealed no significant differences between marcha batida and marcha picada, yet confirmed both are distinct four-beat dissociated gaits. Breed-specific differences were observed, with Campolina horses exhibiting longer dissociation intervals. This highlights the model’s ability to capture subtle, biologically relevant locomotor variations directly from acoustic data, paving the way for refined breed standardization and technical training.
Acoustic Biomarkers for Gait Analysis
Root Mean Square Energy (RMS), Zero-Crossing Rate (ZCR), and Mel-Frequency Cepstral Coefficients (MFCCs) were found to be powerful descriptors for equine gait. PCA showed that while these features differentiate breeds and gait types, a cautious interpretation is needed due to potential extrinsic factors. However, functionally interpreted acoustic variables serve as promising objective biomarkers, offering unprecedented granularity in assessing hoof-ground contact patterns and ground surface interaction.
Pioneering Non-Invasive Equine Phenotyping
This study introduces a novel, non-invasive method for equine gait analysis by leveraging deep learning on acoustic signals. Through robust preprocessing, data augmentation, and an LSTM neural network, we've demonstrated a scalable and low-cost alternative to traditional subjective or expensive kinematic methods. Future research with standardized data acquisition will further enhance the model's generalization and diagnostic capabilities, transforming equine phenotyping.
