Abstract
The effect of repetitive magnetic stimulation on spasticity was evaluated in 38 patients with multiple sclerosis in a double-blind placebo-controlled study. One group was treated with repetitive magnetic stimulation (n=2l) and the other group with sham stimulation (n=l7). Both groups were seated twice daily for 7 consecutive days. Primary end-points of the study were changes in the patients self-score, in clinical spasticity score, and in the stretch reflex threshold. The self-score of ease of daily day activities improved by 22% (P=0.007) after treatment and by 29% (P=0.004) after sham stimulation. The clinical spasticity score improved 3.3±4.7 arbitrary unit (AU) in treated patients and 0.7±2.5 AU in sham stimulation (P-0.003). The stretch reflex threshold increased 4.3±7.5 degls in treated patients and-3.8±9.7 degls in sham stimulation (P=0.001). The data presented in this study supports the idea that repetitive magnetic stimulation has an antispastic effect in multiple sclerosis. Future studies should darify the optimal treatment regimen.
