先天性肌病（CM）患者由于颈部伸肌收缩而导致的颈部伸展常导致继发于下颌张开的低位舌。我们假设，在对照组的颈部延伸将重现较低的位置的舌头类似于发现在CM患者。一个简单的方法，制定了评估舌位置的舌压力上颌磨牙。将一对压力传感器连接到CM患者和四名对照受试者的上磨牙的颊面和舌面。在颊和舌压力的变化记录在颈部伸展位置的CM患者和在自然的头部位置和颈部伸展的对照组。CM患者颈后伸位颊舌压力差异显著：舌压力未检测到，表明舌与上磨牙无接触。对照组受试者在自然头部位置的颊侧和舌侧压力大致相等。然而，对照组受试者在颈部伸展期间颊侧和舌侧压力均降低，其中舌侧压力的降低幅度大于颊侧压力。这些发现表明，在控制对象的颈部延伸再现CM患者中观察到的舌的较低位置。我们建议，压力传感器可以评估舌头的位置，但需要进一步的调查。
Neck extension because of contraction of cervical extensor muscles often brings about a lower-positioned tongue secondary to jaw opening in patients with congenital myopathy (CM). We hypothesized that neck extension in control subjects would reproduce the lower position of the tongue similar to that found in a CM patient. A simple method was formulated to evaluate the tongue position in terms of tongue pressure on the maxillary molar. A pair of pressure sensors was attached to the buccal and lingual surfaces of the upper molar for both the CM patient and four control subjects. Changes in the buccal and tongue pressures were recorded at the neck extension position for the CM patient and during both the natural head position and neck extension for the control subjects. There was a remarkable difference between buccal and tongue pressures in the neck extension position in the CM patient: tongue pressure was not detected at all, indicating there was no contact between tongue and upper molar. The buccal and tongue pressures were approximately equal in the natural head position in the control subjects. However, both buccal and tongue pressures were reduced during neck extension in the control subjects, with a greater decrease in the tongue pressure than the buccal pressure. These findings suggest that neck extension in a control subject reproduces the lower position of the tongue observed in CM patients. We propose that the pressure sensor enables evaluation of the tongue position, but further investigation is required.
