: 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. : 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). : Rehabilitation had a notable impact on MIP in Group 2 (PR + IMT), with a highly significant difference between pre- and post-rehabilitation distributions ( < 0.0001). At the same time, Group 1 (PR-only) showed no significant changes ( = 0.27). In Group 1 (Control), pre- and post-rehabilitation comparisons reveal slight non-significant changes for SLS EO ( = 0.16), ABC ( = 0.07), TUG ( = 0.06), and BBS ( = 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 ( < 0.0001), ABC ( < 0.0001), TUG ( < 0.0001), and BBS ( < 0.0001). : 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.
