Abstract
The development of on-board sensors, such as inertial measurement units (IMU), has made it possible to develop new methods for analyzing horse locomotion to detect lameness. The detection of spatiotemporal events is one of the keystones in the analysis of horse locomotion. This study assesses the performance of four methods for detecting Foot on and Foot off events. They were developed from an IMU positioned on the canon bone of eight horses during trotting recording on a treadmill and compared to a standard gold method based on motion capture. These methods are based on accelerometer and gyroscope data and use either thresholding or wavelets to detect stride events. The two methods developed from gyroscopic data showed more precision than those developed from accelerometric data with a bias less than 0.6% of stride duration for Foot on and 0.1% of stride duration for Foot off. The gyroscope is less impacted by the different patterns of strides, specific to each horse. To conclude, methods using the gyroscope present the potential of further developments to investigate the effects of different gait paces and ground types in the analysis of horse locomotion.
Highlights
The analysis of the locomotion is an essential point for the monitoring of the physical integrity of the sport horse [1]
Eight horses were equipped with kinematic markers, with a radius of 5 mm and 10 mm
The stride cycle detection with wavelets seems more reliable because this method is focused on the shape of the curves themselves correlated to the stride pattern [40,54]. The application of this method to different paces and types of ground surfaces will require the adjustment of the type of wavelets. This study made it possible to compare different methods of stance phases detections from an inertial measurement units (IMU) positioned on the cannon bone
Summary
The analysis of the locomotion is an essential point for the monitoring of the physical integrity of the sport horse [1]. The anatomical structures of the horse0 s limb are subjected to high mechanical stress during locomotion [3]. Mechanical stress could be emphasized by the nature of the ground [4] or the movement performed [5] i.e., landing after jumping a vertical fence [6]. These mechanical stresses repeated during the sporting exercise can lead to micro-lesions possibly leading to more serious injury causing lameness [7]. This leads to large veterinary costs and convalescence for the horse
