Many tools used for recording the response to botulinum toxin treatment are disease‐specific, observer‐based and cumbersome to implement in service settings, especially where clinics treat a variety of disorders. Physicians, clinics, researchers, and patients themselves could benefit from a practical and generic patient‐reported outcome tool. The Liverpool botulinum toxin effects chart (LIVECHART) is a patient‐administered questionnaire developed and used informally over 25 years in a major UK botulinum toxin treatment clinic. In preparation for more formal validation studies, this cross‐sectional study aimed to understand how well LIVECHART captures the effects of botulinum toxin treatment, using patients with cervical dystonia as exemplars.
