Abstract

An abnormal gait is not uncommon in patients with medically unexplained neurological symptoms, including those with other psychogenic movement disorders (PMDs). Previous studies have not evaluated the gait characteristics of patients with a variety of PMDs and there are no reports comparing PMDs with and without gait disturbances. We were interested in determining how those with and without additional involvement of gait differed and how PMD patients differed from those with a pure psychogenic gait disorder (PGD) in the absence of another PMD. We investigated gait features in a large series of patients with PMD (n = 279), dividing them into two groups (Group I with a normal gait and Group II with an abnormal gait). Group I included those with PMD with a normal gait and no change in the PMD while walking (I‐1), and those with a change in PMD while walking, but not affecting gait (I‐2). Group II was divided into those with PMD with additional abnormal gait (II‐1) and those with pure psychogenic gait disorder without other abnormal movements (II‐2). Excessive slowing of movement was more common in PMD patients with an abnormal gait (Group II) compared to those without (Group I). Slowness of gait was the most common feature in patients with PMD combined with a PGD (II‐1) and buckling of the knee pattern was the most common type of pure PGD (II‐2), followed by astasia–abasia. © 2006 Movement Disorder Society

## Abstract Psychogenic movement disorder is defined as abnormal movements unrelated to a medical cause and presumed related to underlying psychological factors. Although psychological factors are of both clinical and pathophysiological relevance, very few studies to date have systematically assess
