Finger-to-nose Under (hypometria) and over (hypermetria) shooting of a target (dysmetria) and the decomposition of movement (the breakdown of the movement into its parts with impaired timing and integration of muscle activity) are seen with appendicular ataxia.	ii
Foot rapid alternating movements Movements are slow and irregular with imprecise timing of agonist and antagonist muscle action.	ii
Toe-to-finger Same as finger-to-nose except for the lower extremities. For both the upper and lower extremities, it is important to always compare right versus left.	ii
Heel-to-shin The patient with ataxia of the lower extremity will have difficulty placing the heel on the knee with a side-to-side irregular over- and undershooting as the heel is advanced down the shin. Dysmetria on heel-to-shin can be seen in midline ataxia syndromes as well as cerebellar hemisphere disease so there is overlap between the two types of ataxias for this finding.	ii
Station Patient's feet will be placed wider apart then usual in order to maintain balance (broad or wide-based station). Midline ataxias cause instability of station with eyes opened or closed.	ii
