Cerebellar ataxia is caused by several hereditary or acquired aetiologies that eventually lead to abnormalities in the cerebellum. Patients with cerebellar ataxia may experience balance issues, eye movement abnormalities, limb incoordination, gait instability, and speech impairment as a result. The available treatment options for cerebellar ataxia are rather limited, causing many patients to struggle with daily activities. Although the success rate of a range of therapeutic interventions has been determined, evidence-based exercise guidelines for the treatment of balance disorders and associated problems in people with cerebellar ataxia are currently unavailable. Thus, physiotherapists must explore novel approaches to successfully manage the symptoms of ataxia and further improve the quality of life of patients. The current study protocol will provide new insight as no article available to date has looked at trunk and pelvis stabilization exercise programme as an intervention for treating cerebellar ataxia. We hereby propose a study, which aims to investigate the impact of conventional exercises and trunk and pelvis stabilization exercises along with conventional exercises on subjects with Cerebellar ataxia in a two-arm randomized controlled trial on improving SARA, TIS, BBS, Barthel Index, WHOQOL The total participants will be divided into two-arm parallel groups and the intervention will be given for complete 6 weeks, 5 days in a week. The outcome measure will be evaluated at baseline and the end of 6 weeks. The results will be evaluated after 6 weeks. If the hypothesis of our study proves to be effective, then this physiotherapy intervention could be included in the management of cerebellar ataxia
