本研究的目的是观察颅颈肌疼痛患者与非患者在头颈姿势、咀嚼肌活动和手部施加的力量方面的差异。观察了 51 名患者和 28 名非患者。当受试者在下颌处于休息、紧握和用纱布紧握的位置进行捏或抓时，记录咬肌的电活动。通过正面和侧面的照片来测量头部和颈部的左右倾斜或伸展和弯曲。结果发现，男性的捏和抓力比女性强，非患者的捏和抓力比疼痛患者强得多。牙齿咬紧的时候，捏握的力量更加强大。用纱布握紧并没有增加，反而更多地降低了手的力量。咬紧牙关时咬肌的活动约为静息活动的 10 至 26 倍。当捏紧或抓握时，活性略有下降。患者的颈部更容易伸展，头部也更伸展。他们的咬肌活动和手部力量明显弱于非患者。
The aim of this study was to observe the difference between patients of craniocervical muscle pain and nonpatients in head-neck posture, masticatory muscle activity, and the force exerted by the hand. Fifty-one patients and 28 nonpatients were observed. The electric activity of the masseter muscles was recorded when the subjects were doing pinching or grasping with the jaw in positions of rest, clenched, and clenched with gauze. Measurement of right and left tilting or extension and flexion of the head and neck was made from photographs of frontal and lateral views. It was found that the pinching and grasping force was much stronger in men than in women and in nonpatients than in patients with pain. The pinching and grasping force was more powerful with the teeth clenched. Clenching with gauze did not increase, but more often decreased the strength of the hand. The activity of the masseter muscle during clenching was about 10 to 26 times that of the resting activity. The activity decreased slightly when clenching with pinching or grasping. Patients were more likely to have a stretched neck with more extension of the head. Their masseter muscle activity and hand force were significantly weaker than that of the nonpatients.
