This study examined the outcomes of 10-week daily resistive inspiratory exercise in 34 adults with advanced multiple sclerosis (MS) in a long-term care facility. Respiratory muscle strength (maximum inspiratory [MIP] and expiratory pressure [MEP]) and fatigue (Modified Fatigue Impact Scale-5) were measured at pretest, post-test, and 8-week retention. Activity participation (days/week attending group social activities) and respiratory infections were analysed during the baseline, exercise, and retention. Participants were aged 60.0±8.5 years and non-ambulatory (Expanded Disability Status Scale = 8.5±0.4). MIP (p=0.02) and activity participation (p=0.019) differed significantly by time. Bonferroni post-hoc analysis revealed that MIP was greater at post-test (41.6%±23.9%) than pre-test (35.6%±22.0%) (p=0.004), and participants attended more social activities during exercise phase (5.0±3.4 days/week) than baseline (4.0±2.1 days/week) (p=0.043). Fatigue did not change by time. Among the participants, 18%, 6%, and 9% had respiratory infections during baseline, exercise, and retention, respectively. Resistive inspiratory exercise improved activity participation without worsening fatigue during the course of exercise in persons with advanced MS.
