Prevention and improvement of sarcopenia by means of skeletal muscle electrical stimulation

本研究的目的是探讨骨骼肌电刺激对老年人骨质疏松症的预防和改善作用。将41例老年人随机分为3组(对照组、电刺激组、电刺激加营养补充组)，观察功能性电刺激对老年人护理预防和生活质量的影响。结果表明，肌肉电刺激联合营养干预组的肌肉横截面积和伸膝力量明显增加。此外，接受肌肉电刺激的23名老年人的脑源性神经营养因子(BDNF)水平随年龄的下降明显降低。

The purpose of this study was to investigate the effects of skeletal muscle electrical stimulation upon prevention and improvement of sarcopenia in the elderly. Forty-one elderly persons were divided into three groups (Control, Electrical stimulation Group, Electrical Stimulation with nutritional supplement Group) in order to determine the effects of functional electrical muscle stimulation upon care-prevention and QOL of the elderly. Results indicated that electrical muscle stimulation together with nutritional intervention group demonstrated significant increases in muscle cross sectional area and knee extension strength. In addition, 23 elderly persons who received electrical muscle stimulation demonstrated a significantly lower decline in the age-associated decrease in brain derived neurotrophic factor (BDNF) level.
