Limb ataxia is a term used to describe a type of ataxia that affects the upper limbs, resulting in incoordination and tremor. It is characterized by dysmetria, dyssynergia, and intention tremor, and is clinically assessed by the finger-to-nose and heel-to-knee tests. Limb ataxia is often used as a component of the NIH Stroke Scale, which is used to assess the severity of a stroke. In this context, limb ataxia refers to abnormal limb coordination, and is only scored if the patient is able to move the limb and the precision of movement is abnormal out of proportion to weakness.
