What Is the SARA Score for Ataxia Progression?

The Scale for the Assessment and Rating of Ataxia (SARA) is a standardized, 5-to-10-minute clinical test neurologists use to measure the severity of ataxia symptoms ^[1]. When your neurologist gives you a SARA score, they are assigning a total number from 0 to 40 based on your physical coordination, where 0 means no ataxia and 40 represents the most severe ataxia ^[2][3]. This score provides an objective way to see exactly how your symptoms are changing over time ^[4].

The Eight Tasks of the SARA Assessment

During your appointment, the neurologist will ask you to perform a series of specific physical tests. The SARA assessment consists of exactly eight items, each testing a different aspect of motor coordination ^[3][1]:

• Gait: You will be asked to walk a short distance. The doctor watches for unsteadiness, how wide your steps are, and whether you need support.
• Stance: You will be asked to stand with your feet together, and sometimes with one foot in front of the other, to test your standing balance.
• Sitting: You will sit on an exam bed without back support and with your feet dangling to check your core balance.
• Speech Disturbance: The doctor will listen to you talk, paying attention to dysarthria (slurred or uneven speech caused by muscle coordination issues).
• Finger-Chase Test: The doctor will move their finger around, and you will be asked to follow it with your own finger.
• Nose-Finger Test: You will touch your own nose and then reach out to touch the doctor’s finger, back and forth.
• Fast Alternating Hand Movements: You will quickly flip your hands palm-up and palm-down on your lap to test speed and coordination.
• Heel-Shin Slide Test: While lying down or seated, you will slide the heel of one foot down the shin of your opposite leg to check lower body coordination.

Your performance on each task is graded and then added together to create your total SARA score. Because some skills impact your daily life more than others, the tasks carry different maximum point values—for example, gait is scored out of 8 points, while sitting balance is scored out of 4 ^[2][3].

Why Tracking Your SARA Score Matters

In conditions like autosomal dominant cerebellar ataxia (often referred to as spinocerebellar ataxia or SCA), symptoms change slowly. It can be difficult for both you and your doctor to notice tiny differences from month to month. Tracking your SARA score annually helps your neurologist measure disease progression objectively rather than relying on memory or guesswork ^[4][5].

A higher score generally corresponds to a greater impact on your daily life, and tracking it can help predict your future needs for physical therapy, walking aids, or home modifications ^[5][6].

It is completely normal to feel emotionally exhausted or anxious when taking this test. Watching a doctor objectively quantify changes in your body can be difficult. It is also important to remember that progression is not always constant ^[7]. You might see small fluctuations in your score—going up slightly one visit and stabilizing the next. Factors like fatigue, stress, a poor night’s sleep, or fighting off a mild illness can make your ataxia temporarily worse on the day of the test ^[8].

While progression rates vary widely depending on the exact subtype of ataxia and the age your symptoms began, a typical progression for many genetic ataxias might be an increase of 1 to 2 points per year ^[4]. Therefore, a slight bump in your score does not necessarily mean a rapid decline in your day-to-day abilities.

Finally, because SARA is considered a highly reliable reference tool in research, knowing your score can help determine if you are eligible for certain clinical trials ^[3][4][1]. Experimental treatments rely on this scale to prove whether a new therapy is effective at slowing the disease.
