Abstract

Introduction: Physical exercise favorably affects visceral adipose tissue (VAT), which is a risk factor for cardiometabolic diseases. However, many people are unable or unwilling to conduct frequent and intensive exercise programs that have favorable effects on VAT. The present study aimed to determine the effect of time-efficient and joint-friendly whole-body electromyostimulation (WB-EMS) technology on VAT volume in overweight-to-obese adults with osteoarthritis of the knee.

Methods: In total, 46 women and 26 men (58.4 ± 7.0 years; BMI: 30.2 ± 4.2 kg/m²) with femuro-tibial knee osteoarthritis were randomly allocated to WB-EMS (n = 36) with 1.5 × 20 min/week for 29 weeks or a usual care control group (CG: n = 36) with six sessions of physiotherapy. Magnetic resonance imaging (MRI) using a non-contrast enhanced two-point Dixon gradient echo volumetric interpolated breath-hold examination determined the VAT from mid L2 to mid L3.

Results: In summary, VAT volume increased non-significantly in the CG (p = 0.246) and decreased non-significantly in the WB-EMS group (p = 0.143). We failed to determine significant WB-EMS-induced effects, i.e., group differences for absolute changes in the VAT volume (p = 0.090). However, we observed gender differences with significantly higher effects in men than in women (p = 0.032).

Discussion: We conclude that low volume, non-superimposed WB-EMS is not a perfect tool for decreasing VAT, particularly in overweight-to-obese women.

全身肌电刺激对超重至肥胖成人膝骨关节炎患者内脏脂肪组织体积的影响：一项随机对照研究。

体育锻炼有利于内脏脂肪组织（VAT），这是心脏代谢疾病的危险因素。然而，许多人不能或不愿意进行频繁和高强度的运动项目，这对增值税有有利的影响。本研究旨在确定时间效率和关节友好型全身肌电刺激（WB-EMS）技术对超重至肥胖膝关节骨关节炎成人VAT体积的影响。方法：女性46例，男性26例(58.4±7.0岁；BMI: 30.2±4.2 kg/m2)的股骨-胫骨膝关节骨性关节炎患者随机分为WB-EMS组（n = 36）和常规护理对照组（n = 36），分别进行1.5 × 20分钟/周的理疗，疗程为29周。磁共振成像（MRI）采用非对比增强两点Dixon梯度回声容积内插式屏气检查确定了从L2中部到L3中部的VAT。结果：综上所述，CG组的VAT体积无显著性增加（p = 0.246）， WB-EMS组的VAT体积无显著性减少（p = 0.143）。我们未能确定显著的wb - ems诱导效应，即VAT体积绝对变化的组间差异（p = 0.090）。然而，我们观察到性别差异，男性的影响明显高于女性（p = 0.032）。讨论：我们的结论是，小体积，非叠加的WB-EMS不是降低增值税的完美工具，特别是对于超重到肥胖的女性。
