title: Integrated EMG feedback in the management of spasmodic torticollis and focal dystonia: a prospective study of 80 patients.
abstract: In summary, then, without consideration of specific circuits or transmitter agents, one can conceive of a hypothetical model that involves both learning and the functional nature of the defect in torticollis and focal dystonia to describe the results obtained. The model must be further elaborated upon and tested, preferably in a quantitative manner. Naturally, the specific finding of a defective transmitter agent (e.g., GABA) such as described in parkinsonian syndrome (dopamine) or the interruption of a specific pathway that causes and improves a dyskinesia is desirable. In this chapter we have described the use of integrated EMG feedback for the treatment of focal dystonia or spasmodic torticollis. Although we have achieved significant results, it remains clear that further research in the treatment of these disorders is required. However, since this treatment does not require medication or surgery and the possibility for significant improvement is greater than 40%, it should be attempted in patients with focal dystonia or torticollis prior to other forms of therapy. SFT should be considered as a standard mode in the medical armamentarium used for the treatment of these disorders, either primarily or in conjunction with other forms of medical, surgical, and physical therapy.
