Psychomotric Perspectives of Rehabilitation in Chronic Brachial Plexus Palsies

Background. The perspective of ongoing electric signals within the motor cortex, conditioned by continuous rehabilitation strategies (doubled by adherence to the treatment protocol), is of interest related to understanding how cerebral plasticity is being modulated in adult traumatic brachial plexus (BP) lesions. Very often, patients with chronic BP lesions tend to be less compliant to rehabilitation therapy over time, since multiple reconstructive microsurgery interventions may not always offer a proper upper limb functionality, especially in severe, complex BP cases. Material and methods. In order to asses the ongoing psychomotric projection of the limb’s representation among the motor cortex, in relation with long term rehabilitation protocol we followed up a group of 11 chronic patients, by transcranial magnetic stimulation (TMS) during a time-lapse of two years. Results. Although modest in relation with amelioration of the deficit on the MRC scale, the patients had mild improvements of the parameter latency, but more important, by assessing the amplitude of the motor evoked potential (MEP), we observed a dynamism of the motor area. This we consider suggestive for ongoing psychomotor components stimulated by rehabilitation: ideomotricity, perceptual-motor coordination, laterality and body representation, as a foundation in maintaining a proven measurable potential of continuous neuroplasticity. Conclusion. From clinical perspective, since psychomotricity actually means interdisciplinarity, this is the common denominator found in the collaboration between medical specialties: plastic surgery and reconstructive microsurgery, clinical neurology, electrodiagnostic and neuromotor rehabilitation.
