Gait disorders are seen frequently and often have a neurological cause. The clinical management of patients presenting with a gait disorder is often complicated due to the large number of diseases that can cause a gait disorder and to the difficulties in interpreting a specific gait disorder properly. In addition, the currently available classification systems are confusing. Gait disorders can be classified into the following categories: antalgic, paretic-hypotonic, spastic, vestibular, ataxic, hypokinetic-rigid, cautious, or functional. A correct interpretation of the gait disorder is important as this determines the diseases to be considered, the auxilliary investigations that have to be carried out, and the selection of rational therapeutic options.
