Effects of Prefrontal Transcranial Direct Current Stimulation on Retention of Performance Gains on an Obstacle Negotiation Task in Older Adults
Neuromodulation. 2022 Apr 8:S1094-7159(22)00561-X. doi: 10.1016/j.neurom.2022.02.231. Online ahead of print.ABSTRACTOBJECTIVES: Complex walking in older adults can be improved with task practice and might be further enhanced by pairing transcranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex. We tested the hypothesis that a single session of practice of a complex obstacle negotiation task paired with active tDCS in older adults would produce greater within-session improvements in walking performance and retention of gains, compared to sham tDCS and no tDCS conditions.MATERIALS AND METHODS: A total of 50 older adults (mean age = 74.46 years ± 6.49) with self-reported walking difficulty ... read more
