Accelerometry-Based Step Count Validation for Horse Movement Analysis During Stall Confinement.

Abstract: Quantitative tracking of equine movement during stall confinement has the potential to detect subtle changes in mobility due to injury. These changes may warn of potential complications, providing vital information to direct rehabilitation protocols. Inertial measurement units (IMUs) are readily available and easily attached to a limb or surcingle to objectively record step count in horses. The objectives of this study were: (1) to compare IMU-based step counts to a visually-based criterion measure (video) for three different types of movements in a stall environment, and (2) to compare three different sensor positions to determine the ideal location on the horse to assess movement. An IMU was attached at the withers, right forelimb and hindlimb of six horses to assess free-movement, circles, and figure-eights recorded in 5 min intervals and to determine the best location, through analysis of all three axes of the triaxial accelerometer, for step count during stall confinement. Mean step count difference, absolute error (%) and intraclass correlation coefficients (ICCs) were determined to assess the sensor's ability to track steps compared to the criterion measure. When comparing sensor location for all movement conditions, the right-forelimb vertical-axis produced the best results (ICC = 1.0, % error = 6.8, mean step count difference = 1.3) followed closely by the right-hindlimb (ICC = 0.999, % error = 15.2, mean step count difference = 1.8). Limitations included the small number of horse participants and the lack of random selection due to limited availability and accessibility. Overall, the findings demonstrate excellent levels of agreement between the IMU's vertical axis and the video-based criterion at the forelimb and hindlimb locations for all movement conditions.

Summary

This research article focuses on the validation of accelerometry-based step count in horses during stall confinement using inertial measurement units (IMUs). The researchers found that the IMU’s vertical axis placed at the forelimb and hindlimb accurately captures the horse’s step counts.

Objective of the Study

  • The study sought to quantify equine movement during stall confinement, helping veterinary professionals detect early signs of reduced mobility due to injuries.
  • The researchers had a dual objective: (1) to compare IMU-based step counts against a visually-based method (video recording) for various types of movements in stall confinement (2) to determine the optimal sensor position on the horse for assessing movement.

Methodology

  • The researchers used an inertial measurement unit (IMU) attached at three different positions on six horses: the withers (the highest part of the horse’s back), right forelimb, and hindlimb.
  • These horses were involved in free movement, circles, and figure-eight movements, recorded in 5-minute increments, to identify the best sensor placement for counting steps during stall confinement.
  • The researchers analyzed data from all three axes of the triaxial accelerometer in the IMU to derive the step counts.

Findings

  • The results showed that the right-forelimb vertical-axis delivered the best results (ICC = 1.0, % error = 6.8, mean step count difference = 1.3 steps).
  • This was closely followed by the right-hindlimb (ICC = 0.999, % error = 15.2, mean step count difference = 1.8 steps).
  • The study, therefore, suggests that the IMU’s vertical axis at the forelimb and hindlimb delivers excellent agreement with the video-based criterion in all movement conditions.

Limitations

  • The researchers admit that the study had several limitations such as a restricted number of horse participants.
  • They were unable to randomly select test subjects, thus potentially introducing selection bias, which can affect the overall validity of the research.
