Association of Activity Limitations and Lower-Limb Explosive Extensor Power in Ambulatory People With Stroke

The relationships between the explosive lower-limb extensor power (LLEP), measured in W/kg, of the affected (■) and unaffected (□) lower limbs and performance of specific functional activities assessed using the FRT, TUG test, chair-rising time, and comfortable walking velocity. When arms were used for assistance during chair rising and TUG test the data are marked differently (× affected, + unaffected). For clarity the lines of best fit with 95% CIs are included only for the unaffected lower-limb extensor power data.

The relationship between the explosive lower-limb extensor power, measured in W/kg, of the affected (■) and unaffected (□) lower limbs and global indices of activity limitation assessed using FIM instrument, RMI, and NEADL. For clarity the lines of best fit with 95% CIs are included only for the unaffected explosive lower-limb extensor power data.
