Effects of Dual-Task Training on Gait Ability in Older Adults with Mild Cognitive Impairment: A Randomized Controlled Trial Focused on Obstacle Negotiation
Abstract
Highlights What are the main findings? Optical sensor-based gait assessment showed that dual-task gait training with visual adaptation improved spatiotemporal gait performance in older adults with MCI. The largest gains occurred during level walking and predictable obstacle negotiation, whereas unpredictable obstacle conditions showed more selective improvements in adaptive gait control. What are the implications of the main findings? Technology-assisted dual-task rehabilitation may improve balance, executive function, and fall-related confidence in older adults with MCI. Sensor-derived gait metrics may help quantify treatment effects during complex walking tasks and support digitally enabled gait rehabilitation research. Abstract Older adults with mild cognitive impairment (MCI) often show gait impairment during dual-task walking and obstacle negotiation. This assessor-blinded randomized controlled trial investigated whether dual-task gait training with visual adaptation, added to a general exercise program, improves gait and related functional outcomes in older adults with MCI. Forty participants aged 65 years or older who met the MCI criteria were randomly allocated to a dual-task gait training with visual adaptation group or a control group (n = 20 each). Spatiotemporal and adaptive gait parameters were assessed before and after 4 weeks of intervention during level walking and during predictable and unpredictable obstacle negotiation under light and noise conditions.…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 20 participants or records.
