Abstract
Introduction: This study examined whether a single session of combined transcranial direct current stimulation (tDCS) and guided mindfulness yields benefits for static and dynamic single-leg balance and pain in athletes with patellofemoral pain syndrome (PFPS).
Materials and Methods: Ten athletes with PFPS completed a pilot randomized, sham-controlled crossover trial. Participants received active tDCS-mindfulness and sham-mindfulness in randomized order with a 1-week washout; they were blinded to condition. Both sessions lasted 20 min with the anode over C3 at 2 mA while participants listened to a brief guided mindfulness recording. In the sham condition, current was ramped down after 30 seconds. Static and dynamic single-leg balance were assessed using the Biodex Balance System (BBS), and pain intensity was rated on a 10-cm visual analogue scale (VAS). Outcomes were compared using analysis of covariance.
Results: Active tDCS-mindfulness improved overall static and dynamic balance and reduced pain compared with sham (p < 0.05). No significant differences were observed for the anteroposterior or mediolateral balance subcomponents (p > 0.05).
Conclusion: A brief combined tDCS-mindfulness session may produce immediate improvements in balance and pain in athletes with PFPS. This approach could represent a promising option for practitioners in time-limited settings, pending confirmation in larger trials.
