Effects of transcranial direct current stimulation on joint flexibility and pain in sedentary male individuals

Summary The aim of this study was to analyze the effects of cathodal tDCS (c-tDCS) on joint flexibility and pain perception in a sedentary male. Eight male healthy, sedentary right-leg-dominant and novice in muscle stretching aged between 19 and 30 years (24.0 ± 4.0 years) were recruited. Subjects performed three experimental conditions in a randomized, double-blinded crossover design: anodal stimulation (a-tDCS), c-tDCS and sham-tDCS (2 mA for 20 minutes targeting the bilaterally motor cortex). Before and immediately after the experimental conditions (baseline and post-condition, respectively), subjects completed the range of motion (ROM) of right hip test and the Visual Analogic Scale for Pain (VAS pain; level of significance P  P  P  P  P  P  P  P
