Abstract：
Background and Objectives: Improving extrapulmonary symptoms in COPD through respiratory muscle training can help alleviate the burden of respiratory symptoms, reduce fatigue, and improve exercise capacity in patients with COPD. This, in turn, can enhance physical activity, balance, and gait, ultimately improving the overall quality of life for individuals with COPD. This study aimed to investigate the effects of respiratory muscle training on balance and gait in patients with moderate to severe COPD. Materials and Methods: We included 65 patients with moderate to severe COPD randomly assigned to either the pulmonary rehabilitation protocol group (PR) or the pulmonary rehabilitation and inspiratory muscle training group (PR + IMT) for three weeks. Patients performed a spirometry, maximal inspiratory and expiratory pressure (MIP/MEP), 6 min walking test (6MWT), activities-specific balance confidence (ABC) scale questionnaire, Berg Balance Scale (BBS), timed up and go test (TUG), and single-leg stance test (SLS). Results: Rehabilitation had a notable impact on MIP in Group 2 (PR + IMT), with a highly significant difference between pre- and post-rehabilitation distributions (p < 0.0001). At the same time, Group 1 (PR-only) showed no significant changes (p = 0.27). In Group 1 (Control), pre- and post-rehabilitation comparisons reveal slight non-significant changes for SLS EO (p = 0.16), ABC (p = 0.07), TUG (p = 0.06), and BBS (p = 0.13). In contrast, in Group 2 (Cases), there are significant improvements in all variables after rehabilitation compared to the pre-rehabilitation values: SLS EO (p < 0.0001), ABC (p < 0.0001), TUG (p < 0.0001), and BBS (p < 0.0001). Conclusions: Our research demonstrated that respiratory muscle training significantly positively impacts balance and gait performance among patients with moderate to severe COPD compared to a control group.
摘要：
背景与目的：通过呼吸肌训练改善COPD患者肺外症状有助于减轻呼吸道症状负担。减少疲劳,改善COPD患者的运动能力。这个,反过来,可以增强身体活动，balance,和步态，最终改善COPD患者的整体生活质量。本研究旨在探讨呼吸肌训练对中重度COPD患者平衡和步态的影响。材料和方法：我们纳入了65例中度至重度COPD患者，随机分为肺康复方案组（PR）或肺康复和吸气肌训练组（PRIMT），为期三周。病人做了肺活量测定,最大吸气和呼气压力（MIP/MEP），6分钟步行测试（6MWT），特定活动平衡信心(ABC)量表问卷，伯格平衡量表（BBS），定时并进行测试（TUG），和单腿站立测试（SLS）。结果：康复对第2组（PR+IMT）的MIP有显著影响，康复前后分布差异显著(p<0.0001)。同时,第1组（仅PR）没有显着变化（p=0.27）。在第1组（对照）中，康复前和康复后的比较显示SLSEO有轻微的不显著变化(p=0.16)，ABC（p=0.07），TUG（p=0.06），和BBS（p=0.13）。相比之下,在第2组(案件)中，与康复前值相比，康复后所有变量都有显著改善：SLSEO(p<0.0001)，ABC（p<0.0001），TUG（p<0.0001），和BBS（p<0.0001）。结论：我们的研究表明，与对照组相比，呼吸肌训练对中度至重度COPD患者的平衡和步态表现显着积极影响。
