We used a robotic exoskeleton to quantify specific patterns of abnormal upper limb motor behaviour in people who have had transient ischemic attack (TIA). A cohort with TIA was recruited within two weeks symptom onset. All individuals completed robotic-based assessment 8 behavioural tasks related and proprioceptive function, as well cognitive function. Robotic task performance compared large controls without neurological impairments corrected for the influence age. Impairment defined below 5th percentile controls. Participants were also assessed National Institutes Health Stroke Scale (NIHSS) score, Chedoke-McMaster Assessment (CMSA) arm, Behavioural Inattention Test (BIT), Purdue pegboard test (PPB), Montreal Cognitive (MoCA). Age-related white matter change (ARWMC), prior infarction cella-media index (CMI) from baseline CT scan that performed 24 hours TIA.
