2. Fig 1
Estimated relative strength cost (%) to ascend (A) and descend (B) stairs without (NH) and with (H) the use of a handrail. Values are mean + SD. *Indicates a significant difference between groups (P<.05). †Indicates a significant difference between sides (P<.05). NOTE. For measures at the ankle: NH, n=7; H, n=9. For all other measures: NH, n=8; H, n=10. Abbreviations: Aff, affected side (stroke); LAff, less affected side (stroke).
