Effects of forelimb instrumentation on lameness detection in horses using a portable inertial sensor-based system.

This research investigated if placing a gyroscope sensor on a horse’s forelimb interferes with detecting lameness using a portable inertial sensor-based system (PISBS). The study found that placement did not affect the results, suggesting that gyroscopes can be freely positioned without obscuring lameness detection.

Objective of the Research

• The main objective of this research was to determine whether the placement of a small gyroscope sensor on a horse’s forelimb affects the detection and measurement of lameness in horses using a PISBS.

Study Design

• The study was conducted in a crossover design, where horses were evaluated twice using PISBS. In each evaluation process, the gyroscope was attached alternately to the right forelimb pastern region (as recommended by the manufacturer) or to the left forelimb pastern region.
• The two methods were compared graphically and analyzed using repeat measures ANOVA, Pearson correlation analysis, and Bland-Altman analysis to ensure statistical accuracy.
• The subject of the study was adult horses that showed no visible signs of lameness during a walk.

Results and Conclusions

• The study found no effect of the gyroscope placement on the detection or quantification of lameness in the forelimb or hind limb of the horses.
• These results suggest that affixing a lightweight gyroscope for lameness evaluations using a PISBS does not affect the results of the lameness measurements.
• In other words, placement of the instrument did not cause or mask lameness as per the measurements taken with PISBS.
• Finally, it was concluded that, when necessary, the gyroscope could be attached to the left forelimb instead of the right forelimb.
