Handedness

Mô tả: Hand dominance, or ‘handedness’ (e.g. right-handedness, left-handedness, or ambidexterity), is clinically significant in the context of dominant cortical localising signs andor non-dominant cortical localising signs (see Table 5.15). The side of hand dominance correlates with the side of the dominant cerebral hemisphere and therefore has potential localising value. • Right hand dominance: • 96% of patients have left-sided dominant cerebral hemisphere99 • 4% of patients have right-sided dominant cerebral hemisphere99 • Left hand dominance: • 73% of patients have left-sided dominant cerebral hemisphere99 • 27% of patients have right-sided dominant cerebral hemisphere99

Ý nghĩa lâm sàng: In patients with dominant or non-dominant cortical localising signs, hand dominance has potential localising value.
