研究目的:

本研究旨在通过前瞻性随机对照试验,评价低强度脉冲超声治疗对脓毒症患者胫骨前肌结构完整性与神经肌肉功能的保护作用。 1.明确低强度脉冲超声治疗能否有效延缓脓毒症患者急性期胫骨前肌横截面积及厚度的萎缩进程; 2.探究低强度脉冲超声治疗对患者表面肌电信号(如M波波幅、均方根值)的影响,验证其在改善神经肌肉电生理活动方面的效能; 结合ICU活动能力评分,综合评估该疗法对患者早期运动功能预后的潜在临床价值,从而为ICU获得性肌无力的防治提供一种新型、无创的物理治疗策略。  

Objectives of Study:

This study aims to evaluate the protective effect of Low-Intensity Pulsed Ultrasound treatment on the structural integrity and neuromuscular function of the tibialis anterior muscle in patients with sepsis through a prospective randomized controlled trial. Specifically, the objectives are: 1. To determine whether Low-Intensity Pulsed Ultrasound treatment can effectively delay the atrophy process of the cross-sectional area and thickness of the tibialis anterior muscle during the acute phase in patients with sepsis; 2. To investigate the impact of Low-Intensity Pulsed Ultrasound treatment on surface electromyography signals (such as M-wave amplitude and root mean square value) in patients, and to verify its efficacy in improving neuromuscular electrophysiological activity;By combining these findings with the mobility scale scores in the intensive care unit, this study intends to comprehensively assess the potential clinical value of this therapy for the prognosis of early motor function in patients, thereby providing a novel, non-invasive physical therapy strategy for the prevention and treatment of weakness acquired in the intensive care unit.
