长期练习太极可以调节老年人行走时的皮层-肌肉相互作用：一项横断面研究
Long-Term Tai Chi Practice Modulates Cortical-Muscular Interactions During Walking in Older Adults: A Cross-Sectional Study.
摘要(中文译文)
太极拳运动对老年人步行过程中神经协调的可能影响尚不明确。本研究旨在比较老年太极拳练习者、老年快走者和无运动对照者在步行过程中的皮层功能连接（FC）和皮层肌肉耦合（CMC）。本研究共招募62名参与者，包括老年太极拳练习者（n=20）、老年快走者（n=22）和无运动对照者（n=20）。参与者在进行步行测试时采集数据。通过功能性近红外光谱设备测量皮层氧合血红蛋白（HbO）浓度以评估FC，并计算HbO信号与表面肌电信号之间的CMC。与无运动对照者相比，太极拳练习者在右侧初级运动皮层-左侧辅助运动区（M1-SMA，p=0.006，d=1.081）、右侧初级运动皮层-右侧辅助运动区（M1-SMA，p=0.003，d=1.318）、右侧初级运动皮层-左侧初级躯体感觉皮层（M1-S1，p=0.002，d=1.150）以及M1-S1（p=0.011，d=1.015）表现出更强的FC，且与快走者相比，在M1-S1（p=0.015，d=0.856）表现出更强的FC。此外，与无运动对照者相比，太极拳练习者在左侧胫骨前肌-右侧辅助运动区（TA-SMA，p=0.015，d=0.991）、TA-S1（p=0.006，d=1.096）、MG-SMA（p=0.002，d=1.118）、右侧内侧腓肠肌-右侧辅助运动区（MG-SMA，p=0.015，d=0.962）以及MG-S1（p=0.017，d=0.939）表现出更强的CMC。老年太极拳练习者表现出更强的功能连接和皮层肌肉耦合，这可能有助于改善老年人的姿势控制并降低跌倒风险。
Abstract
The possible effects of Tai Chi exercise on neural coordination during walking in older adults remain unclear. This study aimed to compare cortical functional connectivity (FC) and corticomuscular coupling (CMC) during walking among older Tai Chi practitioners, older brisk walkers, and non-exercise controls. A total of 62 participants were recruited in this study, including older Tai Chi practitioners (n=20), older brisk walkers (n=22), and non-exercise controls (n=20). Participants performed a walking test during which data were collected. The FC was measured using cortical oxygenated hemoglobin (HbO) concentration via a functional near-infrared spectroscopy device, and CMC was calculated between HbO signals and surface electromyography signals. The Tai Chi practitioners showed greater FC in right primary motor cortex-left supplementary motor area (M1-SMA, p=0.006, d=1.081), right primary motor cortex-right supplementary motor area (M1-SMA, p=0.003, d=1.318), right primary motor cortex-left primary somatosensory cortex (M1-S1, p=0.002, d=1.150), and M1-S1 (p=0.011, d=1.015) compared with the non-exercise controls, and greater FC in M1-S1 (p=0.015, d=0.856) compared with the brisk walkers. In addition, the Tai Chi practitioners demonstrated greater CMC in the left tibialis anterior-right supplementary motor area (TA-SMA, p=0.015, d=0.991), TA-S1 (p=0.006, d=1.096), MG-SMA (p=0.002, d=1.118), right medial gastrocnemius-right supplementary motor area (MG-SMA, p=0.015, d=0.962), and MG-S1 (p=0.017, d=0.939) compared to the non-exercise controls. Older Tai Chi practitioners exhibited greater functional connectivity and corticomuscular coupling, which may contribute to improved postural control and reduced fall risk in older adults.
