Abstract

Orthostatic intolerance (OI) is common in Long Covid. Physical counterpressure manoeuvres (PCM) may improve OI in other disorders. We characterised the blood pressure-rising effect of PCM using surface electromyography (sEMG) and investigated its association with fatigue in adults with Long Covid. Participants performed an active stand with beat-to-beat hemodynamic monitoring and sEMG of both thighs, including PCM at 3-minutes post-stand. Multivariable linear regression investigated the association between change in systolic blood pressure (SBP) and change in normalised root mean square (RMS) of sEMG amplitude, controlling for confounders including the Chalder Fatigue Scale (CFQ). In 90 participants (mean age 46), mean SBP rise with PCM was 13.7 (SD 9.0) mmHg. In regression, SBP change was significantly, directly associated with change in RMS sEMG (

$\beta =0.25$

, 95% CI 0.07–0.43, P = 0.007); however, CFQ was not significant. PCM measured by sEMG augmented SBP without the influence of fatigue.

应用表面肌电图表征长期新冠肺炎患者对物理对抗动作的血压反应

直立性不耐受（OI）在Long新冠肺炎中很常见。物理反压操作（PCM）可以改善其他疾病的OI。我们使用表面肌电图（sEMG）表征PCM的血压升高效应，并研究其与长期新冠肺炎成人疲劳的关系。参与者进行了一次积极的站立，并对两条大腿进行了逐搏血液动力学监测和sEMG，包括站立后3分钟的PCM。多变量线性回归研究了收缩压（SBP）变化与sEMG振幅归一化均方根（RMS）变化之间的相关性，控制了包括Chalder疲劳量表（CFQ）在内的混杂因素。在90名参与者（平均年龄46岁）中，PCM引起的平均收缩压升高为13.7（SD 9.0）mmHg。在回归中，SBP的变化与RMS sEMG的变化直接相关（$\β=0.25$，95%CI 0.07–0.43，P=0.007）；但是CFQ并不显著。通过sEMG测量的PCM增强SBP而不受疲劳的影响。

期刊介绍： The IEEE Journal of Translational Engineering in Health and Medicine is an open access product that bridges the engineering and clinical worlds, focusing on detailed descriptions of advanced technical solutions to a clinical need along with clinical results and healthcare relevance. The journal provides a platform for state-of-the-art technology directions in the interdisciplinary field of biomedical engineering, embracing engineering, life sciences and medicine. A unique aspect of the journal is its ability to foster a collaboration between physicians and engineers for presenting broad and compelling real world technological and engineering solutions that can be implemented in the interest of improving quality of patient care and treatment outcomes, thereby reducing costs and improving efficiency. The journal provides an active forum for clinical research and relevant state-of the-art technology for members of all the IEEE societies that have an interest in biomedical engineering as well as reaching out directly to physicians and the medical community through the American Medical Association (AMA) and other clinical societies. The scope of the journal includes, but is not limited, to topics on: Medical devices, healthcare delivery systems, global healthcare initiatives, and ICT based services; Technological relevance to healthcare cost reduction; Technology affecting healthcare management, decision-making, and policy; Advanced technical work that is applied to solving specific clinical needs.
