Abstract:

Introduction: Multiple sclerosis (MS) is one of the most common neurological disorders. Many studies have shown that MS associated with postural control impairment. The aims of this study were to investigate the short-term and long-term effects of postural training along with transcranial direct electrical stimulation (tDCS) over the cerebellum on balance and postural stability in patients with MS. Method and Materials: This randomized clinical trial study was performed on 36 participants with MS. The participants were randomly assigned to three groups (experimental, sham and control). In all groups, the postural training program was progressively conducted on Byodex Balance System (BBS) during 20 minutes, three sessions per week for four weeks. In the experimental group, 2 mA anodal tDCS (a-tDCS) over the cerebellum was applied along with 20-minute postural training, while in the sham group, cerebellar a-tDCS turned on only for 30 seconds along with the postural training. In the control group, the patients performed the 20-minute postural training, without having tDCS. The balance and the postural stability indices were evaluated using berg balance scale and BBS, respectively, at baseline, immediately and one-month after the intervention. Results: The results of this study indicated that the experimental group as well as the sham and control groups could significantly increase the berg balance scores and decrease the postural stability indices immediate after intervention (p<0.05). However, the improvement in the experimental group was significantly higher than the sham and control groups immediately after intervention (p<0.05). In addition, this improvement in the experimental group was maintained after one-month follow-up (p<0.05), while it was not maintained in the other two control groups after one-month intervention (p> 0.05). Conclusion: Postural training can improve the balance and postural control in patients with MS. The cerebellar a-tDCS along with postural training can increase the lasting effects of this intervention on the improvement of balance and postural control in patients with MS.
