A prospective case control investigation was conducted to assess corticomuscular coherence (CMC) under different balance conditions in order to identify alterations that may arise due to forward head posture (FHP). Sixty-four participants (between the ages of 18-25) were recruited for this study. Participants were free from any musculoskeletal symptoms and matched for relevant demographic variables. Participants were assessed for FHP using the craniovertebral angle (CVA) and separated into either the normal head posture (NHP) group by CVA > 50° or the FHP group by CVA < 50°. Participants were evaluated using the Biodex balance system while both EEG and EMG signals which were acquired simultaneously to investigate CMC. Balance was investigated under four conditions increasing in challenge: (1) standing with eyes open, (2) standing with eyes closed, (3) unstable standing with eyes open with the Biodex set on level 8, and (4) unstable standing with eyes closed with the Biodex at level 8. In addition to recording delta, beta, theta, alpha, and gamma waves, we calculated both peak and average coherence values from the CMC analysis. Statistically significant differences were identified for the FHP group vs. the NHP group for both peak (p < .001) and average CMC values (p < .001) and for the interaction of balance difficulty (stage 1 vs. stage 4), p < .01. Similarly, all brain waves (delta, beta, theta, alpha, and gamma) demonstrated statistically significant differences between the NHP and FHP groups (p < .001) and for increasing balance difficulty across the four stages, p < .05. This study demonstrates that FHP is associated with a significant elevation of CMC, a unique compensatory burden on the brain, particularly during physically challenging balance tasks.
进行了一项前瞻性病例对照研究,以评估不同平衡条件下的皮质肌肉连贯性(CMC),以便识别可能因头部前倾姿势(FHP)而出现的变化。本研究招募了64名参与者(年龄在18 - 25岁之间)。参与者无任何肌肉骨骼症状,并在相关人口统计学变量上进行了匹配。使用颅椎角(CVA)评估参与者的FHP,并根据CVA>50°分为正常头部姿势(NHP)组或根据CVA<50°分为FHP组。使用Biodex平衡系统对参与者进行评估,同时采集脑电图(EEG)和肌电图(EMG)信号以研究CMC。在四种难度逐渐增加的条件下研究平衡:(1)睁眼站立,(2)闭眼站立,(3)Biodex设置在8级时睁眼不稳定站立,以及(4)Biodex在8级时闭眼不稳定站立。除了记录δ波、β波、θ波、α波和γ波外,我们还从CMC分析中计算了峰值和平均连贯性值。FHP组与NHP组在峰值(p<.001)和平均CMC值(p<.001)以及平衡难度的交互作用(第1阶段与第4阶段)方面存在统计学显著差异,p<.01。同样,所有脑电波(δ波、β波、θ波、α波和γ波)在NHP组和FHP组之间以及在四个阶段中平衡难度增加时均表现出统计学显著差异,p<.05。这项研究表明,FHP与CMC的显著升高有关,这是大脑独特的代偿负担,尤其是在身体挑战性的平衡任务期间。
