Transcranial Direct Current Stimulation Combined With Tai Chi for Dual-Task Mobility and Cognitive Function in Older Adults With Cognitive Decline

Résumé succinct

This randomized clinical trial evaluated the effects of transcranial direct current stimulation (tDCS) combined with Tai Chi on dual-task mobility, cognitive function, and physical function in older adults with mild cognitive impairment or self-reported memory concerns. Participants were randomly assigned to receive either Tai Chi combined with tDCS or Tai Chi alone for 8 weeks. Assessments were conducted at baseline and at Weeks 8, 20, and 32. Outcome measures included dual-task Timed Up and Go (DT-TUG) time, single-task TUG, dual-task cost, Montreal Cognitive Assessment-Basic (MoCA-B), Digit Span Test, balance, gait, lower-extremity function, health-related quality of life, sleep quality, anxiety, and depressive symptoms.
