To investigate the effects of water-based exercise training on postural balance in individuals with chronic obstructive pulmonary disease (COPD), and compare the effects of two similar protocols of land- and water-based exercise programmes on postural balance in this population.
Randomised clinical trial.
University-based, outpatient, physical therapy clinic.
Fifty individuals with COPD.
Participants were assigned at random to the land group (LG; n=27) or the water group (WG; n=23), and underwent high-intensity endurance and strength training three times per week for 3months.
Functional balance was assessed by the timed up and go test (TUG), and static balance was assessed with a force platform in the following conditions: standing with feet hip-width apart and eyes open; standing with feet hip-width apart and eyes closed; standing on a short base; and one-legged stance.
Seventeen subjects completed the intervention in the LG {nine males, mean age 64 [standard deviation (SD) 8] years, mean forced expiratory volume in 1 second (FEV) 48 (SD 17) %predicted} compared with 14 subjects in the WG [nine males, mean age 65 (SD 8) years, FEV 51 (SD 15) %predicted]. Water-based exercise training had a positive effect on functional balance [TUG: mean difference -1.17 (-1.93 to -0.41 95% confidence interval) seconds; P=0.006], whereas static balance remained unaltered for both groups. There was no between-group difference in postural balance after exercise training; however, a higher proportion of participants who had a clinically relevant improvement in the TUG were in the WG (LG 35%, WG 64%; P<0.001).
Functional balance improved after 3months of high-intensity exercise training performed in water. Despite the environment, non-specific training seems to be insufficient to improve static balance.

研究水基运动训练对慢性阻塞性肺疾病（COPD）患者姿势平衡的影响，并比较两种类似的陆地和水基运动方案对该人群姿势平衡的影响。
随机临床试验。
以大学为基础的门诊物理治疗诊所。
50 名 COPD 患者。
参与者被随机分配到陆地组（LG；n=27）或水上组（WG；n=23），每周进行 3 次高强度耐力和力量训练，持续 3 个月。
功能性平衡通过计时起立行走测试（TUG）评估，静态平衡通过测力平台在以下条件下评估：双脚分开与肩同宽，睁眼站立；双脚分开与肩同宽，闭眼站立；站在短底座上；单腿站立。
LG 组有 17 名受试者完成了干预（9 名男性，平均年龄 64 [标准差（SD）8]岁，预测第 1 秒用力呼气量（FEV）48 [SD 17]%），而 WG 组有 14 名受试者（9 名男性，平均年龄 65 [SD 8]岁，FEV 51 [SD 15]%）。水基运动训练对功能性平衡有积极影响[TUG：平均差异-1.17（-1.93 至-0.41，95%置信区间）秒；P=0.006]，而两组的静态平衡均未改变。运动训练后两组间的姿势平衡无差异；然而，TUG 有临床相关改善的参与者中，WG 组比例更高（LG 组 35%，WG 组 64%；P<0.001）。
高强度水中运动训练 3 个月后，功能性平衡得到改善。尽管环境不同，非特异性训练似乎不足以改善静态平衡。
