[Gait disturbances in neurology].

Gait disorders lead to loss of mobility and therefore of an individual's autonomy. The greatest risk factor for gait disorders is old age. Other important factors include drugs and their side effects, cognitive impairment, and alcohol abuse. In successful aging there is only a slight decline in gait velocity. The classification into lower- (peripheral), middle- (spinal, basal ganglia), and higher-level gait disorders (e.g. frontal or psychogenic) is still common but contradictory. Gait disorders in neurology are frequent. Detailed descriptions of gait patterns in hypokinetic gait disorders, dystonic, hemi-, and paraparetic gait, ataxia, vestibular, neuromuscular, and psychogenic gait are given. Besides reduction of risk factors, improving the physical state (physiotherapy, sports), descriptions of walking aids, and the prevention of falls are extraordinarily important for the therapy of gait disorders.
