A-1 7 Limb Ataxia assesses for unilateral cerebellar lesions by evaluating coordination and control of limb movements. The test is conducted with the patient's eyes open to observe how visual input affects their coordination. If the patient has a visual defect, testing should be performed in the intact visual field to ensure accurate assessment. The finger should be moved in a smooth, controlled manner to detect any ataxia or irregularities in movement.
