Inclusion criteria: primary research studies, adults post-stroke, severity of upper limb motor impairment and\/or activity limitation described. We classified included papers by assessing descriptor precision: \u2018green\u2019 (studies including descriptors that used recommended outcome measures, cut-offs or central tendency and dispersion), \u2018red\u2019 (descriptors only), and \u2018amber\u2019 (remaining studies). Of the \u2018green\u2019 studies, we identified the most commonly reported descriptors and measures, and computed cut-off scores using non-parametric statistics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>From 17,273 records, 750 studies were included. The most commonly used severity descriptors were \u2018mild, and\/or moderate, and\/or severe,\u2019 used in 580 (77%) of studies. For the Fugl-Meyer Assessment (Upper Extremity) (57 studies, 8% of the total number of studies included), \u2018severe\u2019 ranged from 0 to 25, \u2018moderate\u2019 from 26 to 50, and \u2018mild\u2019 from 51 to 66.
