Feasibility, safety, and patient acceptability of electronic inspiratory muscle training in patients who require prolonged mechanical ventilation in the intensive care unit: A dual-centre observational study. Aust Crit Care 2024; 37:448-454. [PMID: 37321882 DOI: 10.1016/j.aucc.2023.04.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 04/19/2023] [Accepted: 04/19/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND Inspiratory muscle training (IMT) is an intervention that can be used to rehabilitate the respiratory muscle deconditioning experienced by patients with critical illness, requiring prolonged mechanical ventilation. Clinicians are currently using mechanical threshold IMT devices that have limited resistance ranges. OBJECTIVES The objective of this study was to evaluate the safety, feasibility, and acceptability of using an electronic device to facilitate IMT with participants requiring prolonged mechanical ventilation. METHOD A dual-centre observational cohort study, with convenience sampling, was conducted at two tertiary intensive care units. Daily training supervised by intensive care unit physiotherapists was completed with the electronic IMT device. A priori definitions for feasibility, safety, and acceptability were determined. Feasibility was defined as more than 80% of planned sessions completed. Safety was defined as no major adverse events and less than 3% minor adverse event rate, and acceptability was evaluated following the acceptability of intervention framework principles. RESULTS Forty participants completed 197 electronic IMT treatment sessions. Electronic IMT was feasible, with 81% of planned sessions completed. There were 10% minor adverse events and no major adverse events. All the minor adverse events were transient without clinical consequences. All the participants who recalled completing electronic IMT sessions reported that the training was acceptable. Acceptability was demonstrated; over 85% of participants reported that electronic IMT was either helpful or beneficial and that electronic IMT assisted their recovery. CONCLUSION Electronic IMT is feasible and acceptable to complete with critically ill participants who require prolonged mechanical ventilation. As all minor adverse events were transient without clinical consequences, electronic IMT can be considered a relatively safe intervention with patients who require prolonged mechanical ventilation.

"Inspiratory muscle weakness in acutely hospitalized patients 75 years and over": a secondary analysis of a randomized controlled trial on the effectiveness of multicomponent exercise and inspiratory muscle training. Eur Geriatr Med 2024; 15:83-94. [PMID: 37755683 DOI: 10.1007/s41999-023-00865-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 09/05/2023] [Indexed: 09/28/2023]
Abstract
PURPOSE The impact of hospitalization for acute illness on inspiratory muscle strength in oldest-old patients is largely unknown, as are the potential benefits of exercise and inspiratory muscle training (IMT) during in-hospital stay. DESIGN AND METHODS This was a sub-study of a randomized clinical trial that evaluated the efficiency of a multicomponent exercise program in preventing hospitalization-associated disability. Patients were randomized into control (CG) and intervention (IG) groups. The intervention included two daily sessions of supervised walking, squat, balance, and IMT. Baseline and discharge maximal inspiratory pressure (MIP) and inspiratory muscle weakness (IMW) were determined. The effect of the intervention on inspiratory muscle strength was assessed by analyzing (1) the differences between groups in baseline and discharge MIP and IMW, (2) the association, patient by patient, between baseline and discharge MIP, and the improvement index (MIP discharge/baseline) in patients with or without IMW. RESULTS In total, 174 patients were assessed (mean age of 87), 57 in CG and 117 in IG. Baseline MIP was lower than predicted in both sexes (women 29.7 vs 44.3; men 36.7 vs 62.5 cmH2O, P < 0.001, baseline vs predicted, respectively). More than 65% of patients showed IMW at admission. In women in IG, the mean MIP was higher at discharge than at admission (P = 0.003) and was the only variable that reached expected reference levels at discharge (Measured MIP 39.2 vs predicted MIP 45 cmH2O, P = 0.883). Patients with IMW on admission showed a statistically significant improvement in MIP after the intervention. CONCLUSION IMW is very prevalent in oldest-old hospitalized with acute illness. Patients might benefit from a multicomponent exercise program including IMT, even during short-stay hospitalization. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov; No.: NTC03604640. May 3, 2018.

J Clin Hypertens (Greenwich) 2023; 25:971-982. [PMID: 37803506 PMCID: PMC10631095 DOI: 10.1111/jch.14655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Revised: 03/06/2023] [Accepted: 03/07/2023] [Indexed: 10/08/2023]
Abstract
The aim of this study was to evaluate the hypotensive effect and optimal protocol of inspiratory muscle resistance training (IMST). Randomized controlled trials using IMST to lower blood pressure (BP) were retrieved from 12 databases as of July 2022. A meta-analysis of BP and heart rate variability (HRV) was performed and a trial sequence analysis was performed using trial sequential analysis (TSA) software. Twelve articles (n = 386 participants) from five countries were included, with a mean quality score of 5.83. IMST achieved significant results in reducing systolic, diastolic, and mean arterial pressure (-7.93 [-12.08, -3.78]; -3.80 [-6.08, -1.53]; -4.90 [-13.76, 3.96]). Furthermore, TSA has shown that the findings for systolic and diastolic BP are conclusive. Finally, considerable variation remained between studies when analyzing HRV. The overall hypotensive effect of IMST was demonstrated by the TSA and was well tolerated in different populations. Of these, two interventions, high resistance or low resistance combined with slow breathing, showed the best efficacy under an 8-week exercise intervention. In addition, the process of lowering BP by modulating sympathetic vagal activity has not been further confirmed in this study. Future long-term interventions, especially those over 3 months, are needed to observe the prolonged antihypertensive effects and modulatory mechanisms; controlling for variables such as respiratory rate and executing more rigorous studies to further explore antihypertensive options.

Abstract
OBJECTIVES The MIP (maximum inspiratory pressure) and MEP (maximum expiratory pressure) are sensitive indicators of respiratory muscle function. The aim of the study was to assess the function of respiratory muscles in patients after COVID-19 infection, before and after hospitalisation at the Pulmonary Rehabilitation Ward. MATERIALS AND METHODS The study was conducted on a group of 19 people with laboratory-confirmed COVID-19 infection, who, in the period from 1 February to 31 May 2021, were hospitalised at the Independent Public Pulmonary Hospital and underwent respiratory rehabilitation in hospital conditions. A statistical analysis was performed using the STATISTICA package, ver. 10. A respiratory pressure meter (RP Check) was used to measure muscle strength. Measurements were performed twice on each patient-before admission and after hospitalisation in the Pulmonary Rehabilitation Ward. RESULTS We show that conducting pulmonary rehabilitation contributes to the increase in MIP and MEP, which are associated with increased strength of the inspiratory and expiratory muscles. The average value of MIP increased by 11.95 cmH2O and MEP by 26.16 cmH2O. The improvement was visible in both female and male patients. CONCLUSIONS Pulmonary rehabilitation contributes to the improvement of respiratory muscle function indicators among patients after COVID-19 infection. Assessment of the MIP and MEP indices is a simple and quick way to reliably assess the function of the respiratory muscles.

Abstract
BACKGROUND The S-Index assessed by means of electronic devices is a measure of Inspiratory Muscle Strength (IMS) that highly correlates with the maximal inspiratory pressure (MIP). The variables involved when using regression models for the prediction of IMS/MIP depend on both the sample characteristics and the device or protocol used. In light of the scarce information on the influence of physical activity (PA) on IMS in healthy older adults (OA), together with the incorporation of new assessment devices, the objectives of this research are: 1) to determine which factors influence the IMS in a group of trained OA, using a portable electronic device; and 2) to propose a regression model to improve its assessment and training. METHODS One hundred and fifty-nine individuals were assessed for body composition, lung capacity, IMS, and PA. A total of 92 individuals (72.73 ± 4.99 years) were considered for the final sample. RESULTS Using age, sex, and weight as control variables, forced expiratory volume in the first second (FEV1) is the variable which is most likely to be included in the model (80%), without physical fitness appearing to be decisive. In the absence of spirometric variables, cardiorespiratory fitness (6MWT) takes on this role in a predictive model (16%). CONCLUSIONS This is the first study proposing IMS predictive formulas considering spirometry and/or physical fitness results for a Spanish, healthy, and trained OAs population. A predictive formula including also the spirometric variables (mainly the FEV1) might better predict the inspiratory muscle strength. In addition, physical and respiratory functions confirm to be different, so it is necessary for the inspiratory muscles to be trained in a specific way.

Abstract
The 2019-2020 coronavirus pandemic elucidated how a single highly infectious virus can overburden health care systems of even highly economically developed nations. A leading contributor to these concerning outcomes is a lack of available intensive care unit (ICU) beds and mechanical ventilation support. Poorer health is associated with a higher risk for severe respiratory complications from the coronavirus. We hypothesize that impaired respiratory muscle performance is an underappreciated factor contributing to poor outcomes unfolding during the coronavirus pandemic. Although impaired respiratory muscle performance is considered to be rare, it is more frequently encountered in patients with poorer health, in particular obesity. However, measures of respiratory muscle performance are not routinely performed in clinical practice, including those with symptoms such as dyspnea. The purpose of this article is to discuss the potential role of respiratory muscle performance from the perspective of the coronavirus pandemic. We also provide a theoretical patient management model to screen for impaired respiratory muscle performance and intervention, if identified, with the goal of unburdening health care systems during future pandemic crises.

Abstract
BACKGROUND Alternatives to acute hospital admission are required to accommodate the increasing pressures on health services. Since physiotherapists and occupational therapists are integral to inpatient teams, they may also be integral to admission replacement services, and thus their roles in these services merit investigation. AIMS Primarily to determine the presence and roles of physiotherapists and occupational therapists in services replacing acute hospital admission. The secondary outcome is to determine the impact of therapists in such services. METHODS Five electronic databases were searched, with keywords related to therapy, discharge, and admission replacement. Inclusion criteria were that studies explicitly described at least one therapist role within a service replacing acute hospital admissions. Two authors independently reviewed all potentially eligible studies. Two reviewers independently assessed data extracted from included studies into a standardized data extraction form. RESULTS Fifteen studies (3 Hospital at Home, 12 Early Supported Discharge) were included. Both clinical (eg, exercise prescription) and non-clinical (eg, organization and study outcome assessments) therapist roles were described in different admission substitution services. Some roles were only reported among teams, not individually ascribed to therapists. CONCLUSIONS The roles of therapists in services that replace hospital admission are rarely described in detail, with wide variation in reported roles, including across service types and patient populations. This review could not determine the impact of individual therapists on patient or service-level outcomes. Future studies need to more clearly define therapist roles and impact.
