Effect of Needle and Extracorporeal Shockwave Stimulation of Acupuncture Points on Equine Chronic Multilimb Lameness Using a Single-Formula Approach

Abstract Objective The aim of this study was to compare effects with conventional (needle and electroacupuncture, NAP) shockwave stimulation acupuncture points (SAP) on chronic multilimb lameness in horses. Study Design Randomized crossover block design; ten mature Standardbred mares (< 4/10) underwent 3-weekly point stimulations (NAP/SAP) selected the basis their uniform applicability. Groups were reversed following a washout period (9 weeks). Lameness at trot video recorded quantified objectively using an inertial sensor-based system during 4-week pre- post-treatment period. Blinded expert review recordings resulted subjective qualitative (better, same, or worse) quantitative outcome measures (0–10 grade). Mixed effect repeated analyses performed objective gait parameters specific fore (Vector sum [VSHead]) hindlimb (average differences minimum [DIFFMINPelvis] maximum pelvic height [DIFFMAXPelvis]) Qualitative data assessed non-parametric tests. Results SAP had no forelimb but improved (DIFFMINPelvis; p < 0.001). NAP associated deterioration (VSHead, 0.001) lameness. VSHead differed between modalities when accounting for time observation (interaction effect; = 0.002). For other parameters, difference not observed. greater animal comfort compared pre-treatment assessments (p 0.036). Typically, improvement occurred by one two grades. Conclusion same treatment outcome. slightly did alleviate all Given non-invasive nature SAP, method may have potential management
