| Summary: | Despite many research studies, transcranial magnetic stimulation (TMS) is not yet an FDA-approved clinical therapy for dystonia patients. This review describes the four major challenges that have historically hindered the clinical translation of TMS. The four challenges described are limited types of clinical trial designs, limited evidence on objective behavioral measures, variability in the TMS clinical response, and the extensive TMS parameters to optimize for clinical therapy. Progress has been made to diversify the types of clinical trial design available to clinical researchers, identify evidence-based objective behavioral measures, and reduce the variability in TMS clinical response. Future studies should identify objective behavioral measures for other dystonia subtypes and expand the optimal TMS stimulation parameters for clinical therapy. Our review highlights the key progress made to overcome these barriers and gaps that remain for TMS to develop into a long-lasting clinical therapy for dystonia patients.
