Subjects with Bell's palsy and healthy individuals were treated with moxibustion thermal stimulation on the Hegu (LI4) acupoint; an infrared thermal imaging system was used to observe facial-temperature changes. Bell's palsy patients developed low or high temperatures at the affected side, with poor symmetry. Healthy people showed high temperatures on the forehead, medial angle of the eye, nasal ala and around the lips, but low temperatures on bilateral cheeks, thus forming a "T-type hot area" in the face, with good temperature symmetry. Moxibustion treatment for 11 minutes significantly improved high asymmetry in temperature in the faces of Bell's palsy patients. This evidence indicates that moxibustion treatment on Hegu enables increases in facial temperatures in healthy people and Bell's palsy patients, especially around the lips. Moxibustion stimulation at the Hegu not only improves the global circulation but also has specific effects on the lips in Bell's palsy patients, but the underlying mechanism needs further investigation.
对贝尔氏面瘫患者和健康个体在合谷穴（LI4）进行艾灸热刺激；使用红外热成像系统观察面部温度变化。贝尔氏面瘫患者患侧出现低温或高温，对称性较差。健康人前额、内眼角、鼻翼和嘴唇周围温度较高，而双侧脸颊温度较低，从而在面部形成“T型热区”，温度对称性良好。艾灸治疗11分钟可显著改善贝尔氏面瘫患者面部温度的高度不对称性。这一证据表明，对合谷穴进行艾灸可使健康人和贝尔氏面瘫患者的面部温度升高，尤其是嘴唇周围。合谷穴的艾灸刺激不仅能改善全身血液循环，对贝尔氏面瘫患者的嘴唇也有特定作用，但其潜在机制尚需进一步研究。
