概括

疼痛的关节肌肉显示温度降低和活动减少,而不是过度活跃. 这表明神经抑制可能会导致关节疾病患者的肌肉低活性.

科学领域:

神经学神经学
生物医学工程生物医学工程
口腔和牙面部外科手术

背景情况:

部疾病 (TMD) 是影响肌肉的常见疾病.
在TMD中肌肉疼痛和多动性之间的关系仍在争论中.
需要客观的临床数据来了解TMD相关肌肉疼痛的病理生理学.

研究的目的:

通过客观测量来研究TMD肌肉疼痛的临床表现.
测试一种假设,即TMD的肌肉疼痛与肌肉过度活动有关.
探索热学,算法和表面电肌学 (EMG) 在评估TMD肌肉疼痛中的作用.

主要方法:

一项涉及50名患有TMD的参与者的横截面分析研究.
临床检查,包括前和双侧按摩器肌肉的温度,算法和表面电肌图 (EMG).
症状肌肉与逆侧肌肉和无症状肌肉的比较.

主要成果:

与对照组相比,症状肌肉呈现低辐射和较低温度.
表面EMG分析显示,静止状态下没有肌肉过度活跃.
症状肌肉在关节减压测试后显示肌肉招募能力降低,表明低活性.

结论:

在TMD中肌肉疼痛可能与肌肉低活性有关,而不是过度活跃.
肌肉纤维招募的神经抑制可能是这种低活性的基础.
对于TMD肌肉疼痛的治疗策略应该解决这些神经生理学变化.

Disorders of the Skeletal Muscle

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Myasthenia Gravis: Diagnostic Tests

Myasthenia Gravis: Diagnostic Tests

Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...
