RESEARCH INTERESTS:
My research interests focus on the neurophysiological mechanisms underlying sensorimotor impairments and improvements of hand and foot/locomotor function in adults having sustained a stroke or a trauma and in children born preterm. The idea is to identify neural indicators that may characterize the influence of lesion or of a preterm birth on motor control. Daily motor tasks such as isometric contraction, precision grip, standing, sitting, rising-up from a seat to walk are targeted. The reliability of neural indicators reflecting the modulation of corticospinal and intracortical excitability (whether facilitation or inhibition of brain circuits) is still to be demonstrated in healthy adults and full term children. Using such indicators will help first detect adults and children at risk of long-term disability in neural functioning. Then, this will contribute to follow-up recovery/improvement of sensorimotor function in adults with stroke and follow-up the development in children born preterm. In turn, I am interested in refining diagnosis and prognosis owing to the risk of subsequent lesion due to higher sensitivity of brain tissues, subsequent risk of fall due to faulty coordination for posture and movement, specific dysfunction in cerebral palsy, etc. To this end, changes in spinal reflexes measurement and muscle responses to transcranial magnetic stimulation of brain structures (brain plasticity) are tested together with changes in motor and biomechanical patterns of performance and clinical (including cognitive) outcome measures.
