Summary
# Editorial Summary: Functional Electrical Stimulation in Equine Diagnosis and Treatment Biomechanical assessment has proven valuable in human medicine for identifying neuromuscular dysfunction and pain, yet equine practitioners lack equivalent diagnostic tools that isolate specific movement deficits from the confounding variables of over-ground locomotion. Schils and Ober adapted functional electrical stimulation (FES)—a technology that generates precise, voluntary-like muscular contractions through controlled electrical impulses—from human clinical practice to three equine case studies, demonstrating its application in diagnosing musculoskeletal and neuromuscular control abnormalities. The key advantage of FES lies in its ability to produce dynamic movement assessment whilst the horse remains stationary, thereby eliminating environmental variables and enabling targeted identification of dysfunctional anatomical regions that might otherwise be obscured during ridden or lunged work. The authors' case-based approach suggests FES kinematic data can direct both diagnostic reasoning and inform development of bespoke treatment protocols tailored to identified deficits. For farriers, physiotherapists and veterinarians seeking objective, movement-based evidence to guide intervention decisions—particularly in horses with subtle or persistent neuromuscular complaints—this work indicates FES warrants further investigation as a diagnostic and treatment-monitoring modality that bridges the gap between clinical observation and measurable biomechanical change.

Practical Takeaways
- •FES offers a diagnostic tool to isolate specific musculoskeletal and neuromuscular dysfunction in static position, potentially improving diagnostic accuracy compared to ridden or lunged assessment
- •The controlled movement data from FES can help develop targeted rehabilitation protocols by identifying precise regions of dysfunction
- •FES may reduce diagnostic ambiguity arising from compensatory movement patterns and environmental variables in routine clinical evaluation
Key Findings
- •FES can create action potentials producing musculoskeletal movement nearly indistinguishable from voluntary kinematics in horses
- •FES enables isolation of dysfunctional regions without confounding factors from over-the-ground movement and environmental stimuli
- •FES-derived kinematic information can direct further diagnostics and inform specific treatment protocol development in equine patients
