An interventional study of Aerobic training and Balance training in Spinocerebellar Ataxias, sponsored by Columbia University. Completed at 1 site in United States. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2022-10-12.

The primary aim is to show balance training improves DCD individual's ability to compensate for their activity limitations, but does not impact disease progression.
The second aim is to demonstrate aerobic exercise improves balance and gait in DCD persons by affecting brain processes and slowing cerebellar atrophy.
Individuals with degenerative cerebellar disease (DCD) exhibit gradual loss of coordination resulting in impaired balance, gait deviations, and severe, progressive disability. With no available disease-modifying medications, balance training is the primary treatment option to improve motor skills and functional performance. There is no evidence, however, that balance training impacts DCD at the tissue level.
Aerobic training, on the other hand, may modify DCD progression as evident from animal data. Compared to sedentary controls, aerobically trained DCD rats have enhanced lifespan, motor function, and cerebellar Purkinje cell survival. Numerous animal studies also document that aerobic training has a direct, favorable effect on the brain that includes production of neurotrophic hormones, enhancement of neuroplasticity mechanisms, and protection from neurotoxins.
The effects of aerobic training in humans with DCD are relatively unknown, despite these encouraging animal data. A single study to date has evaluated the benefits of aerobic exercise on DCD in humans, and this was a secondary outcome of the study. Although participants performed limited aerobic training during the study, modest functional benefits were still detected.
The main objective of this project will be to compare the benefits of aerobic versus balance training in DCD. We hypothesize that both aerobic and balance training will improve function in DCD subjects, but that the mechanisms in which these improvements occur differ. 1) Balance training improves DCD individual's ability to compensate for their activity limitations, but does not impact disease progression. 2) Aerobic exercise improves balance and gait in DCD persons by impacting the cerebellum

Exclusion Criteria:
Other neurologic conditions • Heart disease
Participants will be given a stationary exercise bike for home use. They will be instructed to use the exercise bike five times a week for thirty-minute sessions. The exercise intensity prescription will be based on the subject's VO2max determined on pre-test day. The exercise program will start at 60% of intensity per session, and then will be increased by steps of 5% intensity every 2 sessions until participants reach 30 minutes of training at 80% intensity. Participants will be contacted weekly by e-mail or phone to answer any questions about the exercise protocol and will be instructed to log each training session. Subjects will record duration of exercise, perceived exertion, average heart rate, maximum heart rate, and distance.
Behavioral: Aerobic training
Balance Training A physical therapist will tailor a home balance training program for each participant based on pre- training capabilities. Subjects will be asked to perform exercises five times a week for thirty-minute sessions. Both dynamic and static exercises will be performed in sitting and standing positions. Exercises will start with stabilizing in a challenging static position and progress to dynamic arm and leg movements in the same or modified position. Participants will be contacted weekly by e-mail or phone to answer any questions about the exercise protocol and will be required to log their exercise effort in terms of frequency and level of balance challenge. Individuals will be instructed to perform more difficult exercises if balance
Behavioral: Balance training
Aerobic training on stationary bike 5x a week for 30 minutes a day
Training 5x a week for 30 minutes. Standard of care
Cerebellar volume
Cranial MRI will be performed in all participants using a 3-T scanner. Using each individual's T1-weighted image, structural imaging measures of cerebellar brain volume will be derived using the FreeSurfer software package (http:// surfer.nmr.mgh.harvard.edu/). FreeSurfer will automatically assign a neuroanatomic label to each voxel. From this labeling, a set of volumetric regions of interest is defined. The calculated volume within the cerebellar region is adjusted for variations in individual's intracranial brain volume (ICV) which is measured using BrainWash (an automatic - Page 3 of 5 \[DRAFT\] - multi-atlas skull-striping software package). We will process the longitudinal T1-weighted images
Time frame: 6 months
Cognition
The NIH toolbox will be used before and after training to determine impact of training on cognition
Time frame: 6 months
Ataxia severity
The Scale for the Assessment and Rating of Ataxia (SARA) will be done to before and after training. This scale ranges from 0 to 40 with higher scores indicating more ataxia
Time frame: 6 months
Gait speed
Participants will walk 8 meters as fast as possible
Time frame: 6 months
Balance
The dynamic gait index will be performed to test balance
Time frame: 6 months
