The effect of a 4-week elastic resistance training regimen in horses with non-performance limiting hindlimb lameness

Abstract

ObjectivesTo evaluate the effect of the Equiband® system on hindlimb kinematics/kinetics, postural stability, and back pain. AnimalsEight horses with mild hindlimb lameness/asymmetry ProceduresHorses were handwalked in the Equiband® system 5 days/week using a graduated exercise plan for 4 weeks. Hindlimb kinematics (inertial sensor system (ISS)), kinetics (stationary force platforms), postural stability (accelerometer), and back pain (mechanical nociceptive thresholds (MNTs)) were evaluated. ResultsNo significant difference in lameness was seen over the course of the study. Significantly improved hindlimb stance duration symmetry at the trot was seen on force plate analysis. There was a significant decrease in craniocaudal and mediolateral range of motion during quiet standing. Significant increase in mediolateral and significant decrease in craniocaudal range of motion were seen at the walk and trot. On baseline MNTs, significantly lower values were found on the lame side versus non-lame side. At 4 weeks, there was only a significant difference in MNTs between lame and non-lame sides at T13. Clinical relevanceThe results of this study suggest that the Equiband® system is effective at improving hindlimb symmetry, spinal stability, and back pain symmetry to hindlimb lameness.
