- Effects of transcranial direct current stimulation on joint flexibility and pain in sedentary male individualsPublication . Lins, V.; Lattari, E.; Monteiro, Diogo; Cid, Luis; Neto, G. Albuquerque Maranhão; Machado, S.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 < 0.05). In post-condition, c-tDCS was greater than to a-tDCS (P < 0.001), and sham-tDCS (P < 0.001) in the right hip ROM. Hip ROM increased in the post-condition compared to baseline in the c-tDCS condition (P < 0.001). In the a-tDCS condition, hip ROM decreased in the post-condition compared to baseline (P < 0.001). For VAS pain, in post-condition, c-tDCS was less than a-tDCS (P < 0.001), and sham-tDCS (P < 0.001). In the c-tDCS condition, the VAS pain decreased in the post-condition compared to baseline (P < 0.001). This study suggests that c-tDCS applied to SM1 may promote increased in ROM of the hip and decreased and perception of pain.
