What type of gait is characterized by uncoordinated movements and instability?

Ataxic gait is defined by a lack of coordination and instability, often resulting in an irregular walking pattern. This type of gait can be attributed to dysfunction in the cerebellum, which plays a crucial role in balance and motor control. Individuals with ataxic gait may appear to stagger or weave while walking, and they may have difficulty in maintaining a straight path. This uncoordinated movement leads to a wide-based stance, varying stride lengths, and often an increased reliance on visual input for balance.

In contrast, spastic gait usually involves stiff or jerky movements due to increased muscle tone and can reflect conditions like cerebral palsy. Parkinsonian gait is characterized by shuffling, reduced arm swing, and difficulty initiating movements, commonly associated with Parkinson's disease. Antalgic gait is a protective mechanism adopted to avoid pain, leading to a shortened stride on one side. Each of these gaits has its distinct clinical presentation, making ataxic gait identifiable by its hallmark uncoordination and instability.
