概括

肌肉脂肪的透,而不是大小,影响慢性腰痛 (cLBP) 患者的肌肉激活. 康复应该针对cLBP个体的脂肪减少,以提高肌肉性能.

科学领域:

生物医学工程生物医学工程
肌肉骨成像系统的成像
临床生物力学临床生物力学

背景情况:

慢性腰部疼痛 (cLBP) 通常与肌肉质量的改变有关.
了解肌肉质量指标和肌肉激活之间的关系对于有效的康复至关重要.

研究的目的:

在有或没有cLBP的个体中调查电肌图 (EMG) 活动和肌肉质量参数 (CSA,FCSA,FA,FI) 之间的关联.
探索肌肉质量变化如何影响勃起器脊柱 (ES) 和多 (MF) 肌肉在标准化举重任务中的激活.

主要方法:

102名参与者 (60名cLBP,42名no-BP) 在10公斤起重时接受了EMG.
磁力共振成像评估了在L3 (ES) 和L5 (MF) 的肌肉质量指标 (CSA,FCSA,FA,FI).
线性回归模型分析了EMG-肌肉质量关联,根据年龄,性别和BMI进行了调整.

主要成果:

在没有血压的组中,CSA和FCSA与ES肌肉EMG活性负相关 (p<0.05).
在cLBP组中,CSA和FCSA与ES EMG活动没有显著的关联.
在cLBP患者中,ES肌肉中FA/FI增加与EMG活性降低相关 (p<0.05).

结论:

肌肉脂肪透显著影响cLBP患者的肌肉激活幅度,而不是肌肉大小.
与健康个体不同,肌肉大小 (CSA,FCSA) 与cLBP中的肌肉激活没有相关性.
对cLBP的康复策略应优先考虑减少脂肪透以提高肌肉性能.

Classification of Skeletal Muscle Relaxants

Classification of Skeletal Muscle Relaxants

Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
Peripherally acting skeletal muscle relaxants interfere with the neurotransmission at the neuromuscular end plate to induce paralysis during...

Local Anesthetics: Clinical Application as Spinal Anesthesia

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
