Ataxia is a neurological disorder affecting coordination, caused by damage to the cerebellum, brainstem, or related pathways. It can be hereditary (e.g., Friedreich's ataxia) or acquired (e.g., multiple sclerosis, stroke). Though rare, ataxia significantly impacts quality of life and independence. Treatments are limited and mainly focus on multidisciplinary rehabilitation. Accurate assessment is essential, yet current tools like Scale for the Assessment and Rating of Ataxia (SARA) have limitations. This study aims to validate a new scale, named the Ataxia Trunk, Lower And upper extremity Scale (ATLAS), through Rasch analysis, to develop a shorter, reliable version. It will assess internal consistency, construct validity, and inter-rater reliability
