Abstract

This project proposes an innovative approach to assess the biomechanics and gait symmetry of horses used in hippotherapy by integrating morphometric data and inertial sensors. Hippotherapy is well-recognized for its therapeutic benefits, but the subjective selection of horses can limit its effectiveness. Our study aims to develop objective methods to evaluate equine movement, which is crucial for ensuring consistent therapeutic outcomes. Currently, evaluations rely on subjective observations, overlooking biomechanical asymmetries that can affect the horse's movement. This project seeks to objectify hippotherapy horses' biomechanics and gait symmetry by correlating these data with morphometric and angular measurements to develop a scale of asymmetries impacting locomotion and, consequently, therapy. We will evaluate 180 horses of different breeds and morphological types (Brazilian Sport Horse, Quarter Horse, and Arabian) and those selected from hippotherapy programs (of various breeds). The evaluations will include linear measurements, body indices, and angular analysis through processed digital images. The gait analysis will use the EquiMoves® system, with eight strategically positioned inertial sensors. Data will be collected under various movement conditions and analyzed statistically to develop the evaluation scale. This pioneering study will provide a scientific basis for the judicious selection of horses in hippotherapy, enhancing treatments and ensuring consistent therapeutic benefits. The methods developed may be applied to other assessments of equine gait, broadening their clinical and scientific impact. (AU)
