Effect of Dual-Task Training on Gait Performance in Older Adults With Mild Cognitive Impairment: A Pilot Randomized Controlled Trial

To evaluate the efficacy of a virtual reality (VR)–based cognitive-motor dual-task training (CDTT) program on single-task gait performance, dual-task cost (DTC) of gait, and functional outcomes in older adults with mild cognitive impairment (MCI).
