Title: Ankle antagonist coactivation in the double-support phase of walking: stroke vs. healthy subjects
Issue Date: 2015
Abstract: Lesions at ipsilateral systems related to postural control atipsilesional side, may justify the lower performance of stroke subjects duringwalking. Purpose: To analyse bilateral ankle antagonist coactivation duringdouble-support in stroke subjects. Methods: Sixteen (8 females; 8 males)subjects with a first isquemic stroke, and twenty two controls (12 females; 10males) participated in this study. The double support phase was assessedthrough ground reaction forces and electromyography of ankle muscles wasassessed in both limbs. Results: Ipsilesional limb presented statisticalsignificant differences from control when assuming specific roles during doublesupport, being the tibialis anterior and soleus pair the one in which this atypicalbehavior was more pronounced. Conclusion: The ipsilesional limb presents adysfunctional behavior when a higher postural control activity was demanded.
