  1. Abbreviations: RH, Right hand; LH, Left hand; RA, Right affected participant; LA, Left affected stroke; MoCA, Montreal Cognitive Assessment; FIM, Functional Independence Measure, m and t after FIM denote motor and total score, respectively; BIT, Behavioural Inattention Test.
  2. Values in bold indicate p-value < 0.01.
  3. Percentages for stroke group reflect performance above and/or below bounds defined by the healthy population (defined in column: Cut off range (%). Inter-rater values reflect performance assessed in two separate sessions performed by different operators. Last 4 columns display correlations between each parameter and MoCA, FIM and BIT clinical scores. Bottom 5 rows display number of task parameters failed by each group.
