This study investigated the effectiveness of adding neuromuscular electrical stimulation (NMES) to endurance training (ET) and resistance training (RT) on exercise tolerance and balance in COPD patients. 42 patients were assigned randomly to the ET + RT + NMES group (n = 22) or ET + RT group (n = 20). Two training programs were performed including 72 sessions. The center of pressure (CoP) displacement in the mediolateral direction (CoPML), in the anteroposterior direction (CoPAP), and the center of pressure velocity (CoPV) were recorded using a stabilometric platform with eyes open (EO) and eyes closed (EC). Time up and go and Berg Balance Scale tests, 6-minute walking test (6MWT), and the maximal voluntary contraction (MVC) were measured before and after the intervention. The walking distance, the dyspnea, and the heart rate were improved after the training period () for both groups (). The ET + RT + NMES group showed better improvement than the ET + RT group in terms of 6MWD. CoP_ML, CoP_AP, and CoP_V were significantly (; ; , respectively) more improved in EO and EC conditions in the ET + RT + NMES group than the ET + RT group. BBS, TUG, and MVC values improved in both groups after the training (). The performances in TUG and MVC tests were significantly greater in the ET + RT + NMES group than those in the ET + RT group (; , respectively). Combining NMES, RT, and ET improves balance in patients with COPD.

添加神经肌肉电刺激与耐力和抗阻训练对慢性阻塞性肺疾病患者运动能力和平衡的影响：随机对照试验


本研究调查了在耐力训练（ET）和阻力训练（RT）中添加神经肌肉电刺激（NMES）对慢性阻塞性肺病患者运动耐量和平衡的有效性。 42 名患者被随机分配至 ET + RT + NMES 组（ n = 22）或 ET + RT 组（ n = 20）。开展了两个培训项目，共 72 场次。使用稳定测量平台在睁眼（EO）和闭眼（EC）的情况下记录中外侧方向（CoPML）、前后方向（CoPAP）的压力中心（CoP）位移和压力中心速度（CoPV） ）。干预前后测量Time Up and Go和Berg平衡量表测试、6分钟步行测试（6MWT）和最大自主收缩（MVC）。训练结束后步行距离、呼吸困难和心率均得到改善（ ）对于两组（ ）。 ET + RT + NMES 组在 6MWD 方面表现出比 ET + RT 组更好的改善。 CoP _ML 、CoP _AP和 CoP _V显着（ ; ;分别）ET + RT + NMES 组的 EO 和 EC 条件比 ET + RT 组有更多改善。训练后，两组的 BBS、TUG 和 MVC 值均有所改善（ ）。ET + RT + NMES 组的 TUG 和 MVC 测试表现明显优于 ET + RT 组（ ; ，分别）。结合 NMES、RT 和 ET 可改善 COPD 患者的平衡能力。
