Abstract (EN):
Lesions at ipsilateral systems related to postural control at
ipsilesional side, may justify the lower performance of stroke subjects during
walking. Purpose: To analyse bilateral ankle antagonist coactivation during
double-support in stroke subjects. Methods: Sixteen (8 females; 8 males)
subjects with a first isquemic stroke, and twenty two controls (12 females; 10
males) participated in this study. The double support phase was assessed
through ground reaction forces and electromyography of ankle muscles was
assessed in both limbs. Results: Ipsilesional limb presented statistical
significant differences from control when assuming specific roles during double
support, being the tibialis anterior and soleus pair the one in which this atypical
behavior was more pronounced. Conclusion: The ipsilesional limb presents a
dysfunctional behavior when a higher postural control activity was demanded.
