目的：为了确定一个8周的神经肌肉刺激程序的大腿肌肉的力量和横截面积的难治性心力衰竭患者列出transplantation.Design的影响：42例稳定的病程随机分配到一个刺激组（SG）或对照组（CG）。刺激协议包括双相对称脉冲的频率为50 Hz和开/关制度的2/6 sec.Results：主要结果的措施是等长和等速大腿肌肉力量和肌肉横截面积。我们的研究结果表明，平均增加22.7膝伸肌和35.4膝屈肌肌肉力量。CG保持不变或伸肌强度下降-8.4。横截面积在SG增加了15.5，在CG增加了1.7。结论：日常生活活动能力以及生活质量在SG增加，但在CG没有。SF-36各分量表在SG中显著增加，特别是身体功能增加了+7.5（1.3-30.0），情感角色增加了+33.3（0-66.6），社会功能增加了+18.8（0-46.9），均P < 0.05。在CG中未观察到变化或降低。难治性心力衰竭患者大腿肌肉的神经肌肉电刺激可有效增加肌肉力量和体积，并对生活质量和日常生活活动的感知产生积极影响。
Objective: To determine the impact of an 8-wk neuromuscular stimulation program of thigh muscles on strength and cross-sectional area in patients with refractory heart failure listed for transplantation.Design: Forty-two patients with a stable disease course were assigned randomly to a stimulation group (SG) or a control group (CG). The stimulation protocol consisted of biphasic symmetric impulses with a frequency of 50 Hz and an on/off regime of 2/6 sec.Results: Primary outcome measures were isometric and isokinetic thigh muscle strength and muscle cross-sectional area. Our results showed an increase of muscle strength by mean 22.7 for knee extensor and by 35.4 for knee flexor muscles. The CG remained unchanged or decreased by -8.4 in extensor strength. Cross-sectional area increased in the SG by 15.5 and in the CG by 1.7.Conclusions: Activities of daily living as well as quality of life increased in the SG but not in the CG. Subscales of the SF-36 increased significantly in the SG, especially concerning physical functioning by +7.5 (1.3-30.0), emotional role by +33.3 (0-66.6), and social functioning by +18.8 (0-46.9), all P < 0.05. Neither a change nor a decrease was observed in the CG. Neuromuscular electrical stimulation of thigh muscles in patients with refractory heart failure is effective in increasing muscle strength and bulk and positively affects the perception of quality of life and activities of daily living.
