Barry AJ, et al. - Researchers evaluated the performance of the less affected upper limb in people with stroke, compared with normative values. They also assessed less affected upper limb function in those whose pre-stroke dominant limb became paretic and those whose pre-stroke non-dominant limb became paretic. A total of 40 chronic stroke survivors with severe hand impairment (Chedoke-McMaster Stroke Assessment rating of 2-3 on Stage of Hand) were included in this study. The researchers data from stroke survivors and normative age- and sex-matched data from neurologically intact individuals. Overall, stroke survivors with severe impairment of the paretic limb continue to exhibit significant upper extremity impairment in their nominally nonparetic limb even years after stroke. This was observed regardless of whether the dominant hand or non-dominant hand was primarily influenced. The researchers suggested that nonparetic upper limb should be targeted for rehabilitation, as this group of stroke survivors is particularly dependent on the nonparetic limb for performing functional tasks.
