Effect of gluteus medius activity and step strategy on the multiple stepping threshold toward the paretic side: amplitude and onset of the paretic gluteus medius in people with stroke using crossover steps and side steps toward the paretic side. Side steps resulted in significantly higher multiple stepping thresholds toward the paretic side than no side steps. Individuals who used a side step and reached multiple stepping thresholds within healthy control values (>2.2 m/s²) demonstrated fast and large-amplitude responses in the paretic gluteus medius. These individuals also reached good scores on the clinical tests.
