Summary
# Editorial Summary: Acupuncture and Recurrent Airway Obstruction in Horses Despite growing interest in acupuncture for equine respiratory disease, evidence supporting its use in severe recurrent airway obstruction (heaves) remains limited. Wilson and colleagues conducted a randomised, controlled trial in 10 heaves-affected horses to determine whether acupuncture could objectively improve lung function during an acute exacerbation, comparing treatment efficacy against both sham controls (halter restraint and handling) and a recipe-based acupuncture approach administered by an untrained operator. Objective pulmonary function measurements (maximal pleural pressure change, airway resistance, dynamic compliance, respiratory rate and tidal volume) showed temporal improvements across all treatment groups within the first 4 hours, yet these gains were modest, short-lived (resolving within 24 hours) and indistinguishable between acupuncture and control treatments, indicating that observed improvements were attributable to the handling intervention itself rather than any specific acupuncture effect. Notably, simply removing horses from the dusty stabled environment failed to improve lung function in the initial 6-hour period, suggesting that acute airway obstruction in heaves is not immediately reversible through environmental modification alone. For equine practitioners, this evidence indicates that a single acupuncture session should not be considered an alternative to conventional pharmacological management of heaves exacerbations, though it may provide minor symptomatic relief through non-specific handling effects.

Practical Takeaways
- •Do not recommend acupuncture as a standalone treatment for acute heaves attacks; conventional medical therapies remain the evidence-based standard
- •Any apparent improvement in respiratory signs following acupuncture treatment may simply reflect the calming effect of handling rather than therapeutic acupuncture effect
- •Environmental management (removal from dust exposure) should be prioritized for heaves management, though acute improvements may take longer than 6 hours to manifest
Key Findings
- •Single acupuncture treatment produced no specific improvement in lung function beyond that achieved by handling alone in heaves-affected horses
- •Temporal improvements in pleural pressure, pulmonary resistance, dynamic compliance, respiratory rate, and tidal volume occurred after all treatments but lasted less than 24 hours
- •Most observed improvements in lung function were attributable to the handling procedure rather than acupuncture treatment itself
- •Removal from dusty environment did not produce lung function improvement within the first 6 hours of measurement
