Does the Somatosensory Temporal Discrimination Threshold Change over Time in Focal Dystonia?

Figure 1

Somatosensory temporal discrimination threshold (STDT) in healthy subjects and in patients with focal dystonias (blepharospasm and cervical dystonia). (a) Mean STDT values (expressed in milliseconds) in healthy subjects and patients with dystonia (whole group). (b) Mean STDT values in patients with blepharospasm and cervical dystonia tested upon enrolment and 8 years later. Bars represent standard deviation.
