Pulsating magnetic device may offer benefits for some MS patients - University of Washington News and Information

This double blind study was done on patients with MS and seems to show that there were improvements when these devices were used.

This is welcome as double blind experiments are very hard to do with many complemetary therapies due to the nature of the therapies. The sample size was very small which may throw doubt on the results but this is often the case with mainstream clinical trials too.
