A VISUAL GUIDE TO SARA

Eight observations.
One severity score.

The Scale for the Assessment and Rating of Ataxia helps a trained clinician describe the severity of cerebellar ataxia and follow change over time.

00–4040

No ataxia signs on the scale

Most severe score on the scale

What the clinician observes

Each item contributes a set number of points. Higher scores mean greater impairment on the tasks assessed.

010–8

Gait

Walking, turning, tandem steps, and the level of support needed.

020–6

Stance

Standing with feet apart, together, and in tandem without support.

030–4

Sitting

Maintaining a seated position for 10 seconds without support.

040–6

Speech

Clarity and ease of understanding during normal conversation.

050–4

Finger chase

Following a moving target quickly and accurately with each hand.

060–4

Nose–finger

Reaching between the nose and a target while observing tremor.

070–4

Fast hand movements

Rapidly alternating palm and back of hand with each arm.

080–4

Heel–shin slide

Sliding each heel down the opposite shin with control.

Both sides count. For items 5–8, the clinician scores the right and left sides separately, then uses their arithmetic mean in the total.

A score is a measurement—not a diagnosis.

Useful for: documenting a baseline, describing current severity, and following change across visits or research assessments.

Not designed to: identify the cause of ataxia, predict an individual timeline, or replace a complete neurological evaluation.

Keep conditions consistent: fatigue, illness, medication effects, footwear, mobility aids, and the examiner can affect performance. Ask your clinician how to interpret a change.
