Effect of Low Pulsed Magnetic Field Therapy on The Motor Neuron Excitability in Normal Subjects

[摘要] Background: Pulsed magnetic field therapy has the ability to modulate neuropathic pain. Objective: The aim of our work is to investigate the effect of the low pulsed magnetic field therapy (LPMFT) on the motor neuron excitability in normal subjects Methods: Thirty volunteer male subjects were studied; assigned randomly into two groups; a study group (20 subjects) and a control group (10 subjects). The study group received LPMFT with a frequency of 10Hz and an intensity of 60 G for 30 min at the posterior aspect of the right calf muscle. The H reflex latency, amplitude, H/M ratio and intensity threshold were measured within 30 minutes before and after application of the therapy and 30 minutes after.  Results: A statistically significant decrease in H intensity threshold in the study group was noticed (P< 0. 0001). Conclusion:  Low pulsed magnetic field with a frequency of 10 Hz and an intensity of 60 G can increase the motor neuron excitability, providing us with an effective modality that could be used for the treatment of many neurological disorders.
