Two tools developed at the Institute for Biomedical Technologies and their use in children with obstetric brachial plexus lesions, a rather complex upper limb movement disorder, have been presented in this article. The authors have given examples of useful patterns correlated to defined clinical situations, such as the reinnervation process in a voluntary muscle, the coactivation of antagonistic muscles, and the ill-defined individual motion pattern in an affected limb. The authors believe these dynamic descriptions combining electrophysiologic and video techniques offer excellent clinical possibilities for the future. Further attempts will be made to adapt them to clinical situations and thus contribute to a more objective and better scientific understanding of upper limb movement.
Seventy-four children with obstetric brachial plexus palsy registered with the British Paediatric Surveillance Unit were prospectively followed for a minimum of 2 years. Thirty-nine (52.7%) spontaneously recovered to normal or nearly normal levels and a further 29 (39.3%) regained good function in the upper limb. The most important secondary deformity involved the gleno-humeral joint and 20 patients (27%) needed surgical correction. Two more children await operation for shoulder deformity. The brachial plexus was explored in nine patients (12.2%) and repaired in seven.
