Gait alteration is a change in the manner that a person walks and generally moves about throughout their environment. Depending on the substance, this can often be described as walking in a "robotic", "mechanical", or "zombie-like" manner that although unusual in appearance, does not necessarily impede the person's ability to exert coordination or fine motor control.
Gait alteration is often accompanied by other coinciding effects such as motor control loss and sedation. It is most commonly induced under the influence of moderate dosages of dissociatives such as ketamine, and especially DXM.  However, it may also occur to a lesser extent under the influence of other compounds such as depressants, psychedelics and deliriants.
