“…Dual-task training can improve the speed of attention conversion, improve the ability of attention allocation between tasks, and make the allocation of cognitive resources among different tasks more coordinated [50]. Therefore, our study can be used to guide and formulate targeted task balance control therapy [50] and optimize alternative interventions such as non-invasive brain stimulation [49]. Up-regulation or down-regulation of the excitability of speci c brain areas (such as BA45 and BA10) of PFC may have a certain effect on promoting balance control in older adults with MCI.…”

“…The current research may be of great signi cance in strengthen the balance control strategy of older adults with MCI. The theory of brain plasticity holds that the brain can still show plasticity in the face of cognitive decline in old age [49]. Dual-task training can improve the speed of attention conversion, improve the ability of attention allocation between tasks, and make the allocation of cognitive resources among different tasks more coordinated [50].…”

Background This study aimed to compare the balance ability and functional brain oxygenation in the prefrontal cortex (PFC) among older adults with mild cognitive impairment (MCI) under single and dual tasks, and also investigate their relationship. Neural regulatory mechanisms of the brain in the MCI were shed light on in balance control conditions. Methods 21 older adults with MCI were recruited as the experimental group and 19 healthy older adults as the control group. Participants completed balance control of single task and dual task respectively. Functional near-infrared spectroscopy (fNIRS) and force measuring platform are used to collect hemodynamic signals of the PFC and center of pressure (COP) data during the balance task, respectively. Results The significant Group*Task interaction effect was found in D-ml, 95%AREA, RMS, RMS-ml, RMS-ap, SP, SP-ml, and SP-ap. The significant group effect was detected for five regions of interest (ROI), namely L45, R45, R10, L46, and R11. Under single task, D-ap, RMS, and RMS-ap were significantly negatively correlated with R45, L45, and R11 respectively. Under dual task, both RMS and 95%AREA were correlated positively with L45, and both L10 and R10 were positively correlated with RMS-ap. Conclusion The MCI demonstrated worse balance control ability as compared to healthy older adults. The greater activation of PFC under dual tasks in MCI may be considered a compensatory strategy for maintaining the standing balance. The brain activation was negatively correlated with balance ability under single task, and positively under dual task. Trial registration: ChiCTR2100044221, 12/03/2021.

“…Therefore, high-density EEG outcomes recorded while walking may serve as biomarkers to assess the response to treatment aiming to improve gait in PD [ 24 ], but larger studies are needed. Future studies should investigate the effects of other interventions, particularly non-invasive brain stimulation techniques [ 48 , 49 , 50 ], on sensorimotor EEG outcomes recorded while walking in people with PD. Finally, future studies should consider the effects of disease progression on EEG recordings during walking in PD.…”

The neural correlates of locomotion impairments observed in people with Parkinson’s disease (PD) are not fully understood. We investigated whether people with PD present distinct brain electrocortical activity during usual walking and the approach phase of obstacle avoidance when compared to healthy individuals. Fifteen people with PD and fourteen older adults walked overground in two conditions: usual walking and obstacle crossing. Scalp electroencephalography (EEG) was recorded using a mobile 64-channel EEG system. Independent components were clustered using a k-means clustering algorithm. Outcome measures included absolute power in several frequency bands and alpha/beta ratio. During the usual walk, people with PD presented a greater alpha/beta ratio in the left sensorimotor cortex than healthy individuals. While approaching obstacles, both groups reduced alpha and beta power in the premotor and right sensorimotor cortices (balance demand) and increased gamma power in the primary visual cortex (visual demand). Only people with PD reduced alpha power and alpha/beta ratio in the left sensorimotor cortex when approaching obstacles. These findings suggest that PD affects the cortical control of usual walking, leading to a greater proportion of low-frequency (alpha) neuronal firing in the sensorimotor cortex. Moreover, the planning for obstacle avoidance changes the electrocortical dynamics associated with increased balance and visual demands. People with PD rely on increased sensorimotor integration to modulate locomotion.

“…Brain areas identified as affected by PD during walking and balance tasks are targeted by tDCS protocols (i.e., non-invasive brain stimulation through electrodes placed on the scalp). Lilian's team has demonstrated that tDCS can provide benefits to gait, balance and cognition as a stand-alone intervention and when combined with exercise 25,26,[28][29][30] .…”

Lilian Teresa Bucken Gobbi, or simply Lilian, a beloved friend of many of us, died unexpectedly on October 20, 2022. We wrote this tribute to recognize her legacy in science. We reviewed Lilian's education and career and her contributions to the research on balance and locomotion in children, older adults and people with Parkinson's disease. We also acknowledged her pioneering work on physical activity interventions for people with Parkinson's disease. Finally, but not least important, we tried to show a little bit about the wonderful human being who Lilian was beyond her scientific contributions.
