Brain plasticity can be classified as adaptive and maladaptive. Maladaptive
plasticity indicates hindered functional recovery or the development of an
unwanted symptom. Although a considerable amount is known about adaptive
plasticity in stroke, relatively little is known of maladaptive plasticity. In the current study, previous studies on motor function-related maladaptive plasticity in stroke are reviewed in terms of compensatory movement pattern
(CMP), delayed-onset involuntary abnormal movements (IAMs), and the ipsilateral
motor pathway as a motor recovery mechanism. For successful stroke
rehabilitation, it is important that the characteristics of maladaptive
plasticity are accurately recognized. However, there is a lack of definitive
evidence regarding the recognition of motor function-related maladaptive
plasticity, although it seems that each of the three above-mentioned topics are
involved. As for CMP, patients with a good neurological state as much as having a
normal movement pattern, should be considered to have maladaptive plasticity, and
in terms of the ipsilateral motor pathway, patients with bilateral innervations
can be considered to have maladaptive plasticity. On the other hand, IAMs due to
delayed neuronal degeneration should be ruled out in patients with delayed-onset
IAMs. Therefore, for the accurate recognition of motor function-related
maladaptive plasticity in stroke, a thorough evaluation of neurological state
using brain mapping techniques is necessary, and subsequently, the prevention or
intensive management of maladaptive plasticity is needed.
