Participants will receive up to 5 individualized coaching sessions delivered via telehealth to facilitate and optimize exercise uptake. The therapist will facilitate discussion on specific and measurable goals, and will provide options for tracking their progress, such as written or web-based exercise logs or an activity monitor. The recommended exercises will be individualized to each participant but will primarily focus on increasing general physical activity (e.g. steps per day) as well as engagement in moderate intensity aerobic exercise a minimum of three times per week. Balance and strengthening exercises will also be recommended as appropriate.

Clinical rating scale for severity of ataxia symptoms. This is an 8-item clinical performance based scale, which individuals are graded according to total ataxia severity. Total scores can range from 0 (no ataxia) to 40 (most severe ataxia). Scores are based on performance of the following tasks: 1) Gait, 2) Stance, 3), Sitting, 4) Speech Disturbance, 5) Finger Chase, 6) Nose-Finger Test, 7) Fast alternating hand movements, 8) Heel-shin slide. For the purpose of this study, we will be performing a modified version of the SARA, and be using the first four items of the SARA Scale (Gait, Stance, Walking, Speech) to be administered via telehealth.

The Cerebellar Cognitive Affective Syndrome Scale (CCAS) was developed as a bedside quick screen for Cerebellar Cognitive Affective Symptom (also referred to as Schmalmann's Syndrome). The CCAS is a 10-item scale of cognitive and neuropsychiatric tests detailing executive function, working and verbal memory, language, visuospatial function, abstract reasoning, behavior and affect. Two scores are reported; a raw score ranging from 0 (severe cognitive impairment) to 120 points (no cognitive impairment), as well as a Pass/Fail marker for each of the 10 items on the scale. 1 fail is considered as possible cerebellar cognitive affective symptom, 2 fails are considered probable, and 3 fails are considered clinically definite.

Evaluates both pre-planned and unplanned physical activity. Both pre-planned and unplanned physical activity subsections are separately scored through summation and average. Higher averages (closer to 5) indicate greater physical activity, whereas lower averages (closer to 0) indicate little to no physical activity in either category.

Questions pertaining to salience of exercise identity. Scores range from 0 (no exercise identity) to 45 (high degree of exercise identity).
