Table 1: Gait classification schemes*.

CLASSIFICATION	EXAMPLES	DRAWBACKS
Phenomenological	Antalgic Spastic Hypokinetic-rigid	Pathophysiology not taken into account.
Anatomical	Frontal Cerebellar	Different anatomical lesions may present with similar gait patterns. A given anatomical lesion may present with different gait patterns.
Hierarchical	Lower level Intermediate level Higher level	Symptom overlap between levels. Subdivisons of higher level category difficult to use in clinical practice. Higher level often abused as basket term for poorly understood disorders.
Etiologic	Neurodegenerative Vascular	Ancillary studies or post-mortem often Needed.
