Trans Cranial Magnetic Stimulation for Treatment Refractory Tardive Dyskinesia?

I had read some information on TCMS being used for treatment refractory tardive dyskinesia. I have tried every known treatment and there still are many breakthrough spasms (dystonic, akathestic, myoclonic). Is this showing to be of any help or is it too soon to tell? I had almost signed into a study for TCMS (before it was FDA approved) for the psychosis I experienced from schizoaffective but at the time as a treatment as a whole it was under study. I've made a good recovery from that now but I still need help with the tardive dystonia. Now that TCMS is FDA approved in general I know it would be safe. But is there any evidence it would be effective on tardive dyskinesia, tardive dystonia or other related conditions? Any information would be appreciated. Thanks.
