In their JNNP publication, Nielsen et al1 present data from a randomised controlled trial of 57 patients with functional (psychogenic) motor disorders, such as limb weakness, gait disorder, tremor and dystonia. They are a leading cause of neurological disability at all ages. They may be isolated but more commonly co-occur with other physical and psychological comorbidities such as fatigue, pain and anxiety. Randomised trials are scarce.
