Summary
# Editorial Summary Wearable accelerometers offer considerable promise for monitoring equine performance in endurance events, yet existing systems are prohibitively expensive and limited in their operational range and duration. Yusoff and Azaman validated the Androsensor mobile application—a low-cost smartphone-based alternative—against a laboratory-standard inertial measurement unit (IMU) sensor attached to the forelimb pastern of two Thoroughbreds at walk, trot and canter. The smartphone application demonstrated good correlation with the established IMU device across all gaits (r > 0.5), suggesting reliable acceleration data capture despite operating at a higher sampling rate (200 Hz versus 150 Hz). For farriers, physiotherapists and endurance coaches, this finding is particularly significant: an accessible, wearable monitoring tool could enable longitudinal tracking of gait symmetry, lameness progression and fatigue indicators during competition without the logistical or financial barriers of current equipment. Whilst this preliminary validation involved only two horses, the results support further investigation into smartphone-based gait monitoring as a practical addition to performance assessment protocols for distance events.

Practical Takeaways
- •A low-cost smartphone app (Androsensor) may offer a practical, accessible alternative to expensive gait analysis equipment for monitoring endurance horses during training
- •Wearable sensors placed on the pastern can provide objective gait data useful for detecting early changes in movement quality that might predict injury or fatigue
- •Further validation with larger sample sizes and field testing during actual endurance events is needed before relying on this technology for performance decisions
Key Findings
- •Androsensor mobile application showed good correlation (r > 0.5) with validated IMU sensor for walk, trot, and canter gait recognition
- •Low-cost smartphone-based gait monitoring system demonstrated potential for equine performance monitoring in endurance events
- •Wearable IMU and smartphone sensors attached to forelimb pastern successfully captured and compared acceleration data across three gaits
