Gait Performance and Lower-Limb Muscle Strength Improved in Both Upper-Limb and Lower-Limb Isokinetic Training Programs in Individuals with Chronic Stroke
Table 3
Mean (SD), range, and 95% confidence interval (CI) for the laboratory self-selected and maximal gait speeds (m/s) and mean (SD) for the related peak positive power of the affected plantarflexors, hip flexors, and extensors for the experimental (lower-limb training—) and control (upper-limb training—) groups at pre- and posttraining.
