Abstract
We were interested in the question, if transcranial magnetic stimulation of nerve structures can be used in the objective description of motor impairment in humans with lumbosacral radiculopathies. We could demonstrate, that severe clinical motor deficit and changes of evoked muscle potentials correlate to a high degree. In contrast to electrical stimulation, magnetic impulses are not painful and offer the advantage of a selective activation of motor systems. Applications of the method in Orthopaedics involve perioperative control of motor capacity, description of radicular motor damage and the diagnosis of peripheral nerve lesions. Although the value of the method for orthopaedic purposes is not yet clear, our experiences indicates interesting diagnostic possibilities.
