The association between craniofacial muscles and postural control is well-known because of numerous anatomical connections. However, there are a few conflicting studies that correlated the activity of the masticatory muscles with the distribution of body weight pressure on the feet, which can strongly influence balance. Therefore, the purpose of our study was to evaluate the association between the masseter and temporalis muscle activity and foot pressure distribution. Fifty-two women were recruited, and baropodometric and EMG analyses of the masseter and temporalis baseline activities were analyzed. An ipsilateral association was found between the right temporal muscle activity and the right rearfoot load (r = 0.29, < 0.05) and right forefoot load (r = -0.29; < 0.05), as well as the percentage of muscle activation of the right masseter muscles with the percentage of pressure on the right forefoot (r = 0.31, < 0.05) and right rearfoot (r = -0.31, < 0.05). While further studies are needed, an ipsilateral association was found between masticatory muscles and foot pressure distribution.
由于存在众多解剖学联系，因此颅面肌肉与姿势控制之间的关系是众所周知的。然而，有一些相互矛盾的研究将咀嚼肌的活动与体重在足部的分布相关联，而体重的分布会强烈影响平衡。因此，我们的研究目的是评估咀嚼肌和颞肌活动与足部压力分布之间的关系。招募了 52 名女性，并对咀嚼肌和颞肌的基线活动进行了足底压力分布和肌电图分析。发现右侧颞肌的活动与右侧后足负荷（r = 0.29，<0.05）和右前足负荷（r = -0.29；<0.05）以及右侧咀嚼肌的肌肉激活百分比与右侧前足（r = 0.31，<0.05）和右侧后足（r = -0.31，<0.05）的压力百分比之间存在同侧关联。虽然还需要进一步的研究，但我们发现咀嚼肌和足部压力分布之间存在同侧关联。
