<unk>  (or trunk ataxia) is a wide-based "drunken sailor" gait characterised by uncertain starts and stops, lateral deviations and unequal steps. It is an instability of the trunk and often seen during sitting. It is most visible when shifting position or walking heel-to-toe. As a result of this gait impairment, falling is a concern in patients with ataxia.<unk>  affects the muscles closer to the body such as the trunk, shoulder girdle and hip girdle. It is involved in gait stability.<unk>  is different from appendicular ataxia. Appendicular ataxia affects the movements of the arms and legs. It is caused by lesions of the cerebellar hemispheres.
