People with Parkinson’s disease (PD) frequently exhibit changes in spatiotemporal gait parameters that affect walking abilities. Preliminary studies suggested that dual-task training of gait could enhance walking; nonetheless, it remains unclear whether dual-task training can specifically enhance dual-task gait performance compared to single-task training.

We aim to conduct a systematic review to compare the effect of dual-task training relative to single-task training of gait on specific gait parameters during dual-task tests in subjects with PD.
