Objectives: Identify the effects of inspiratory muscle training (IMT) on walking capacity, strength and inspiratory muscle endurance, activities of daily living, and quality of life poststroke. Design: Double-blind randomized trial. Setting: The Sarah Network of Rehabilitation Hospitals. Subjects: Adult poststroke inpatients with inspiratory muscle weakness. Interventions: The Experimental Group (EG) ( n = 23) underwent IMT for 30 minutes/day, five times/week over six weeks. The Control Group (CG) ( n = 27) performed sham IMT. Both groups underwent standard rehabilitation. Main measures: Primary outcome was post-intervention six-minute walking test (6MWT) distance. We also measured maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), inspiratory muscle endurance, activities of daily living (functional independence measure – FIM), and quality of life at baseline and post-intervention. Three months after intervention, we measured MIP, walking capacity and quality of life. Results: Baseline characteristics were similar, with mean age 53 ± 11 years and FIM 74 ± 10p. Both groups similarly increased the walking capacity at six weeks (63 vs 67 m, P = 0.803). Compared to the CG, the EG increased the inspiratory endurance (22 vs 7 cmH2O, P = 0.034) but there was no variation in MEP (14 vs 5 cmH2O, P = 0.102), MIP (27 vs 19 cmH2O, P = 0.164), FIM (6 vs 6, P = 0.966) or quality of life (0 vs 0.19, P = 0.493). Gains in both groups were sustained at three months. Conclusion: Adding IMT to a rehabilitation program improves inspiratory muscle endurance, but does not further improve MIP, 6-MWT distance, activities of daily living or quality of life of individuals after stroke beyond rehabilitation alone.

Inspiratory Muscle Strength

Abstract Background: In ventilator-dependent ICU patients, inspiratory muscle training may improve inspiratory muscle strength and accelerate liberation from the ventilator, but optimal training parameters are yet to be established and little is known about the impact of inspiratory muscle training on quality of life or dyspnea. Thus we sough to ascertain whether inspiratory muscle training, commenced while ventilator-dependent, would improve outcomes for ICU patients invasively ventilated for 7 days or longer.Methods: In this randomized trial with assessor-blinding and intention-to-treat analysis, 70 participants (mechanically ventilated ≥7 days) were randomized to receive once- daily supervised high-intensity inspiratory muscle training with a mechanical threshold device in addition to usual care, or usual care (control). Primary outcomes were inspiratory muscle strength (maximum inspiratory pressure % predicted) and endurance (fatigue resistance index) at ventilator-liberation and 1 week later, and quality of life (SF-36v2, EQ-5D). Secondary outcomes included dyspnea, physical function, duration of ventilation and in-hospital mortality.Results: 33 participants were randomly allocated to the training group and 37 to control. There were no statistically significant differences in strength (maximum inspiratory pressure) (95% CI -7.4 to 14.0) or endurance (fatigue resistance index) (95% CI -0.003 to 0.436). Quality of life improved significantly more in the training group than control (EQ5D 17.2; 95% CI 1.3-33.0) (SF36-PCS 6.97; 96%CI 1.96-12.00). Only the training group demonstrated significant reductions in dyspnea (-1.5 at rest, -1.9 during exercise). There were no between-group differences in duration of ventilation or other measures. In-hospital mortality was higher in the control group than the training group (9 vs 4, 24% vs 12%, p=0.23).Conclusions: In ventilator-dependent patients, mechanical threshold loading inspiratory muscle training improves quality of life and dyspnea, even in the absence of strength improvements or acceleration of ventilator liberation.

The value of inspiratory muscle training (IMT) in pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) is unclear. The RIMTCORE (Routine Inspiratory Muscle Training within COPD Rehabilitation) randomised controlled trial examined the effectiveness of IMT added to pulmonary rehabilitation.In total, 611 COPD patients (Global Initiative for Chronic Obstructive Lung Disease stage II–IV) received a 3-week inpatient pulmonary rehabilitation, of which 602 patients were included in the intention-to-treat analyses. The intervention group (n=300) received highly intensive IMT and the control group (n=302) received sham IMT. The primary outcome was maximal inspiratory pressure (PImax). The secondary outcomes were 6-min walk distance, dyspnoea, quality of life and lung function. Outcomes were assessed pre- and post-pulmonary rehabilitation. ANCOVA was used.The intervention group showed higher effects in PImax (p<0.001) and forced inspiratory volume in 1 s (p=0.013). All other outcomes in both study groups improved significantly, but without further between-group differences. Sex and pulmonary rehabilitation admission shortly after hospitalisation modified quality of life effects.IMT as an add-on to a 3-week pulmonary rehabilitation improves inspiratory muscle strength, but does not provide additional benefits in terms of exercise capacity, quality of life or dyspnoea. A general recommendation for COPD patients to add IMT to a 3-week pulmonary rehabilitation cannot be made.

IntroductionA significant number of patients with COVID-19 may experience dyspnoea, anxiety, depression, pain, fatigue and physical impairment symptoms, raising the need for a multidisciplinary rehabilitation approach, especially for those with advanced age, obesity, comorbidities and organ failure. Traditional pulmonary rehabilitation (PR), including exercise training, psychosocial counselling and education, has been employed to improve pulmonary function, exercise capacity and quality of life in patients with COVID-19. However, the effects of inspiratory muscle training (IMT) in PR programmes remain unclear. This study aimed to determine whether the addition of a supervised IMT in a PR is more effective than PR itself in improving dyspnoea, health-related quality of life and exercise capacity in symptomatic patients with post-COVID-19.Methods and analysisThis parallel-group, assessor-blinded randomised controlled trial, powered for superiority, aimed to assess exercise capacity as the primary outcome. A total of 138 are being recruited at two PR centres in Brazil. Following baseline testing, participants will be randomised using concealed allocation, to receive either (1) standard PR with sham IMT or (2) standard PR added to IMT. Treatment effects or differences between the outcomes (at baseline, after 8 and 16 weeks, and after 6 months) of the study groups will be analysed using an ordinary two-way analysis of variance.Ethics and disseminationThis trial was approved by the Brazilian National Ethics Committee and obtained approval on 7 October 2020 (document number 4324069). The findings will be disseminated through publications in peer-reviewed journals and conference presentations.Trial registration numberNCT04595097.

Objective: To evaluate the efficacy of an inspiratory muscle training protocol on inspiratory muscle function, functional capacity, and quality of life in patients with asthma. Design: A single-blind, randomized controlled clinical trial. Setting: Community-based. Subjects: Patients with asthma, aged between 20 and 70 years old, non-smokers. Interventions: Participants were randomized into two groups: inspiratory muscle training group performed inspiratory muscle training 5 days a week for 8 weeks, consisting of six sets of 30 breaths per day with a training load ⩾50% of maximal inspiratory pressure, plus an educational program; the control group only received the educational program. Main measurements: Maximal inspiratory pressure, inspiratory muscle endurance, and the distance performed on the incremental shuttle walking test were assessed pre-intervention, post-intervention and at follow-up (3 months after the end of the intervention). The asthma quality of life questionnaire was applied pre and post-intervention. Results: Data from 39 participants were analyzed. Maximal inspiratory pressure in percentage of predicted and endurance test duration were significantly higher post-intervention in the inspiratory muscle training group (∆ post–pre: 50.8% vs 7.3% of predicted – P < 0.001 and ∆ post–pre: 207.9 seconds vs 2.7 seconds – P < 0.001, respectively). There was no significant difference in the incremental shuttle walking distance between groups (∆ post–pre: 30.9 m vs −8.1 m, P = 0.165). Quality of life was perceived as significantly better, without a difference between groups ( P > 0.05). Conclusions: About 8 weeks of inspiratory muscle training in patients with controlled asthma significantly increased inspiratory muscle strength and endurance.

Background: Children with neuromuscular diseases (NMD) are at risk of morbidity and mortality because of progressive respiratory muscle weakness and ineffective cough. Inspiratory muscle training (IMT) aims to preserve or improve respiratory muscle strength, thereby reducing morbidity and improving health-related quality of life (HRQoL).Objectives: To describe the safety and feasibility of a 6-week IMT programme using an electronic threshold device (Powerbreathe®). Any adverse events and changes in functional ability, spirometry, peak expiratory cough flow (PECF), inspiratory muscle strength and HRQoL (Pediatric Quality of Life [PedsQL]) were recorded.Methods: A convenience sample of eight participants (n = 4 boys; median [interquartile range {IQR}] age: 12.21 [9.63–16.05] years) with various NMD were included in a pre-experimental, observational pre-test post-test feasibility study. Training consisted of 30 breaths, twice daily, 5 days a week, for 6 weeks.Results: There were significant pre- to post-intervention improvements in upper limb function and coordination (p = 0.03) and inspiratory muscle strength: maximum inspiratory mouth pressure (Pimax) (p = 0.01); strength-index (p = 0.02); peak inspiratory flow (PIF) (p = 0.02), with no evidence of change in spirometry, PECF or HRQoL. No adverse events occurred and participant satisfaction and adherence levels were high.Conclusion: Inspiratory muscle training (at an intensity of 30% Pimax) appears safe, feasible and acceptable, in a small sample of children and adolescents with NMD and was associated with improved inspiratory muscle strength, PIF and upper limb function and coordination.Clinical implications: Larger, longer-term randomised controlled trials are warranted to confirm the safety and efficacy of IMT as an adjunct respiratory management strategy in children with NMD.
