Objective. We analyze the explanatory hypotheses proposed in most
relevant studies on the different altered movements (AM) in the
unaffected part of the body following a stroke. We report 25 cases of AM
patients whose clinical signs do not correspond with the AM described
in previous studies. A possible explanation could be established from a
different neuroplastic hypothesis. Development. To review the main
hypotheses which try to explain the presence of AM in the part of the
body ipsilesional to the injured hemisphere of the brain. To this end we
overview some updated studies concerning the corticospinal tract
function, and the neuroplastic capacity after a stroke. Simultaneously,
we study 25 cases of patients with cerebrovascular disease and some
clinical findings which present a different type of AM from those
previously reported. Conclusions. Motor alterations described in most
studies concerning stroke patients correspond well to a diminished
selectivity of movements of the unaffected hand, to associated movements
in both upper limbs or to mirror movements. Explanations of these
hypothesis are: the effect of injured fibres of the uncrossed
corticospinal tract and neuroplastic reorganization of the ipsilateral
pathways. The existence of different AM is observed in some clinical
cases which we found to be scarcely studied in published research. These
movements appear in the non-affected part of the body throughout
cerebrovascular disease evolution, and which could be caused by
maintained hypersolicitation of the unaffected part of the body and the
neuroplastic process following a stroke. Further functional neuroimaging
investigations are needed to confirm this clinical hypothesis.
