Abstract:
Objective To compare the effect of transcranial direct current stimulation(tDCS)combined with seated Taijiquan Yun-shou in different sequences on brain functional activation in healthy youths.Methods From September to December,2024,14 healthy young medical interns or probationers were recruited from the Fifth Hospital of Xiamen.They randomly completed three interventions in a crossover design:Yunshou training followed immediately by tDCS(Y-S group),tDCS intervention followed immediately by Yunshou training(S-Y group),and simultaneous implementation of tDCS intervention and Yunshou training(Sim group).Yunshou was practiced in a seated position.For tDCS,the anode was placed over the left primary motor cortex(M1),and the cathode over the right M1.Changes in oxyhemoglobin(HbO2)concentration in the regions of interest were mea-sured using functional near-infrared spectroscopy.Results Three cases dropped down.The brain regions with significant differences before and after intervention included:CH3,CH7 and CH23 of right prefrontal cortex(PFC)in Y-S group;CH12 of left PFC in S-Y group;and CH9,CH10 and CH25 of the left PFC,CH13 and CH14 of the left sensorimotor cortex(SMC),CH15 of the right pre-motor and supplementary motor cortex(PMC),and CH16 of the right SMC in Sim group(P<0.05).After inter-vention,HbO2 concentration was the highest in the bilateral PFC,bilateral PMC and left SMC in the Y-S group(P<0.05);and it was almost the same between Sim group and S-Y group(P>0.05),except that of the right PFC decreased in Sim group.Conclusion The sequential combination of brain-limb integrated regulation is a key factor influencing the immediate cor-tical activation pattern.
