[Gait disorders: mechanisms and classification].
Gait disorders are important because of their prevalence, particularly among the elderly, and the associated risk of falls and injury. The main physiological characteristics of locomotion and neural networks that organize locomotion and maintain balance are briefly reviewed. A simplified classification designed clinical practice and based upon clinical characteristics and more recent data obtained from quantified gait analysis is proposed.
