概括
表面电肌图 (sEMG) 可以通过测量按摩器肌肉活动来区分正常的吞和努力的吞. 这种生物反方法与感知力度相关,有助于吞治疗.
科学领域:
- 运动学习和康复
- 吞的生物力学和生理学
- 生物反和神经康复
背景情况:
- 生物反对于运动学习至关重要,特别是在像吞这样的复杂行为中.
- 表面电肌图 (sEMG) 是评估吞肌肉活动和指导治疗策略的关键生物反工具.
- 努力吞 (EFS) 机动可能会改变吞的生理方面,包括产生压力和生物机械运动.
研究的目的:
- 为了检查是否masseter肌肉sEMG可以区分正常的吞 (NS) 和努力的吞 (EFS).
- 检查吞努力的主观感知与肌肉活动的客观sEMG测量之间的关系.
主要方法:
- 20名健康的成年人参与了这项研究,他们进行了NS和EFS.
- 马塞特的sEMG峰值幅度和持续时间记录在唾液吞期间.
- 参与者使用视觉模拟尺度 (VAS) 评价他们感知的吞力度.
主要成果:
- 与NS相比,EFS显示的masseter sEMG峰幅和持续时间显著更大.
- 在感知吞力 (VAS) 和masseter sEMG峰值幅度之间发现了正相关性.
- 这些发现表明,按摩器肌肉在区分吞类型方面具有实用性.
结论:
- 按摩肌的sEMG活动可以有效地区分正常和费力吞.
- 视觉模拟尺度 (VAS) 是一个有前途的补充工具,用于跟踪患者在吞治疗中的努力.
- 在吞康复中,sEMG和VAS可以很有价值,特别是在先进的生物反技术有限的地方.

01:23Salivary Glands and Saliva
763
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

01:14Muscles for Facial Expressions
2.3K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

01:26Assessment of the Mouth
259
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
