A cross-sectional observational study was performed between December 2013 and December 2014 in 80 patients with primary focal dystonia and 55 neurologically normal control subjects after obtaining informed consent.
Previous studies on patients with primary focal dystonia utilizing TCS have shown a higher prevalence of LN hyperechogenicity in patients compared with controls,[sup][6],[8],[9] which may be the result of moderate copper or manganese accumulation.
sup][27] At present, it is accepted that the frequency of SN hyperechogenicity in patients with primary focal dystonia is comparable to that of healthy controls; our present findings support these observations.
In conclusion, there is a greater prevalence of LN hyperechogenicity, as detected by TCS, in patients with primary focal dystonia than in neurologically normal populations.
