Electroacupuncture shows promise for headshaking in horses

Electroacupuncture has emerged as a promising treatment for horses suffering from trigeminal-mediated headshaking (TMHS), according to a recent study by the Royal Veterinary College (RVC). The research, led by Professor Bettina Dunkel, found that 64% of horses treated showed improvement, with one-third experiencing complete resolution of symptoms.

TMHS causes involuntary, painful head flicking, often rendering horses unrideable. While the condition has no known cure, electroacupuncture—using needles and electrical current to alter nerve pain perception—proved effective in the retrospective study of 42 cases between 2015 and 2024.

The treatment was well tolerated across all horses, with the average severity grade dropping from three to one. Only 4.8% experienced worsening symptoms, and complications were minimal.

Professor Dunkel called the results “very encouraging,” suggesting the technique offers a viable, low-risk option that can be applied on-site. Further refinements, such as adjusting treatment length or frequencies, could enhance outcomes and extend remission.

Equine vet Sue Devereux, who pioneered research into the technique, welcomed the findings: “This confirms electroacupuncture is a worthwhile option for TMHS,” she said, sharing the success story of a once-unrideable dressage mare now back in the ring year-round.

While the exact cause of TMHS remains unknown, this study adds hope for horses affected by the debilitating condition.
