Shell shock at Queen Square: Lewis Yealland 100 years on

Abstract

This article reviews the treatment of functional neurological symptoms during World War I by Lewis Yealland at the National Hospital for the Paralysed and Epileptic in London. Yealland was among the first doctors in Britain to incorporate electricity in the systematic treatment of shell shock. Our analysis is based on the original case records of his treatment of 196 soldiers with functional motor and sensory symptoms, functional seizures and somatoform disorders. Yealland’s treatment approach integrated peripheral and central electrical stimulation with a variety of other—psychological and physical—interventions. A combination of electrical stimulation of affected muscles with suggestion of imminent improvement was the hallmark of his approach. Although his reported success rates were high, Yealland conducted no formal follow-up. Many of the principles of his treatment, including the emphasis on suggestion, demonstration of preserved function and the communication of a physiological illness model, are encountered in current therapeutic approaches to functional motor and sensory symptoms. Yealland has been attacked for his use of electrical stimulation and harsh disciplinary procedures in popular and scientific literature during and after World War I. This criticism reflects changing views on patient autonomy and the social role of doctors and directly impacts on current debates on ethical justification of suggestive therapies. We argue that knowledge of the historical approaches to diagnosis and management of functional neurological syndromes can inform both aetiological models and treatment concepts for these challenging conditions.
