Stringhalt is a neurological condition causing involuntary hindlimb flexion in horses, with Australian stringhalt from plant toxins causing particularly severe welfare impacts.
Severe stringhalt causes significant welfare compromise through impaired ambulation and the distress of uncontrollable, repetitive limb movements. Horses with severe bilateral Australian stringhalt may be unable to walk normally or may fall when attempting to move, causing both physical injury and the psychological distress of loss of normal movement control. The involuntary nature of the condition means horses cannot suppress the movements despite apparent frustration with their own gait. Rapid pasture change to remove the causative plant in Australian stringhalt cases can produce rapid welfare improvement within weeks. Surgical management in true stringhalt cases provides permanent relief for appropriate candidates. Appropriate pain management and rest during acute severe episodes protect welfare while recovery occurs.
