| Abstract |
| Introduction: Transcranial direct current stimulation (tDCS) is a non-invasive approach with minimal side effects that has garnered significant attention for pain management in individuals with knee osteoarthritis. These patients often experience poor motor function due to severe pain and decreased muscle strength. Therefore, the aim of this study was to examine the effects of six sessions of non-invasive anodal of M1 and DLPFC tDCS on pain and motor function in women with knee osteoarthritis. Methods: Fifty-four elderly women with knee osteoarthritis who met the inclusion criteria were randomly assigned to three groups: anodal- M1-tDCS (n=18), anodal- DLPFC - tDCS (n=18), and a Sham-tDCS for control group (n=18). Pain was assessed using a Visual Analog Scale (VAS), and motor function was evaluated through up and go test (3-meter test) and 40-meter walking tests. The interventions consisted of six consecutive 20-minute sessions of anodal tDCS in the M1 and DLPFC areas, administered using a NeuroStim2 device (Iran). Data analysis was conducted using SPSS version 27 software and included mixed ANOVA, paired t-tests, and one-way ANOVA statistical tests. Results: The results indicated that time had a significant effect on all indices (p<0.05), with a significant group effect observed in pain intensity and the 40-meter walk test. However, the interaction of group × time was not significant for any of the indices. The M1 stimulation group exhibited a greater reduction in pain intensity (87.54% vs. 41.76%) and improved function (70.10% vs. 33.7% in the 40-meter test and 36.07% vs. 20.89% in the 3-meter test) compared to the DLPFC stimulation group. Conclusion: Both interventions led to improvements in motor function and pain, with M1 stimulation proving more effective in reducing pain and enhancing lower limb function than DLPFC stimulation. |
