Repetitive peripheral magnetic stimulation. Treatment option for spasticity?

Background. In an open study the effect of repetitive peripheral magnetic stimulation (RPMS) on the spastic talipes equinus of varyious origins, degree and duration was evaluated in 53 children and adolescents. Study design and methods. Clinical and electrophysiological investigations were designed to measure the RMPS effect on the spasticity and the functional capabilities of the spastic talipes equines. Moreover, the duration of the effect of one RPMS session should be established. The magnetic stimulation comprising 10 series of 10 s duration was applied over the first sacral radix using a frequency of 20 Hz and a 1.2-fold intensity above the motoric threshold. Results. The RPMS significantly reduced the tonus of the spastic talipes equines and this effect lasted for 1 week. No significant changes of electrophysiological parameters measuring the F-wave, H-reflex und ASR tendon reflex could be observed. Conclusion. The RPMS could prove to be an effective option for the treatment of spasticity. However, this method needs further evaluation by evidence-based studies.
