“…Patient diaries included data on the total number of completed sessions, repetitions per session and reasons for protocol deviations. Secondary outcome data were obtained with voluntary MIP measurements using MicroRPM™, according to the protocol from a recently published study investigating the course of recovery of respiratory muscle strength among survivors of critical illness ( 14 ). The maximum of 3 MIP measurements was recorded twice: before the start of the training and after 6 weeks.…”

Objective: This study investigates the feasibility of delivering inspiratory muscle training as part of the physical therapy treatment for patients with post-COVID dyspnoea.Design: Mixed-methods pilot study.Subjects/patients: Patients with complaints of dyspnoea after COVID-19 infection and their physical therapists.Methods: The Amsterdam University of Applied Sciences and the Amsterdam University Medical Centers conducted this study. Participants performed daily inspiratory muscle training at home for 6 weeks, consisting of 30 repetitions against a pre-set resistance. The primary outcome was feasibility assessed as acceptability, safety, adherence and patient- and professional experience obtained through diaries and semi-structured interviews. The secondary outcome was maximal inspiratory pressure.Results: Sixteen patients participated. Nine patients and 2 physical therapists partook in semi-structured interviews. Two patients dropped out before initiating the training. Adherence was 73.7%, and no adverse events occurred. Protocol deviations occurred in 29.7% of the sessions. Maximal inspiratory pressure changed from 84.7% of predicted at baseline to 111.3% at follow-up. Qualitative analysis identified barriers to training: ‘Getting acquainted with the training material’ and ‘Finding the right schedule’. Facilitators were: ‘Support from physical therapists’ and ‘Experiencing improvements’.Conclusion: Delivering inspiratory muscle training to patients with post-COVID dyspnoea seems feasible. Patients valued the simplicity of the intervention and reported perceived improvements. However, the intervention should be carefully supervised, and training parameters adjusted to individual needs and capacity. LAY ABSTRACTMany people who have recovered from a COVID-19 infection develop persistent shortness of breath, fatigue and difficulties with memories, learning new things or making decisions. This condition affects their daily life and is called post-COVID syndrome. Inspiratory muscle training is a technique that aims to help people to breathe more easily by strengthening and improving the coordination of breathing muscles. We undertook this study to determine if performing such training was possible for these patients. We interviewed 2 physiotherapists who provided the training and 9 of their patients. In addition, we looked into the diaries 16 patients kept about their training to learn about their experiences or unexpected (medical) problems they might have had with the training. We found that the training seemed reasonable since patients and their physiotherapists found it simple, and no negative experiences happened. However, patients said it helped if the physiotherapist supervised them during the training.

Objective To describe hand grip strength, walking speed, functional mobility, and postural control at one year following intensive care unit admission for COVID-19, and to find any predictors that are associated with impaired hand grip strength, walking speed, functional mobility, or postural control at the 1-year follow-up. Design Retrospective cross-sectional and longitudinal observational study. Setting Intensive care unit and outpatient research clinic at Sahlgrenska University Hospital. Participants Of the 105 individuals in “The Gothenburg Recovery and Rehabilitation after COVID-19 and Intensive Care Unit” cohort, 78 participated in this study. Main measures Descriptive statistics for hand grip strength, walking speed, functional mobility, and postural control were presented and binary logistic regressions were performed to find their significant predictors. Results At 1-year following intensive care unit admission for COVID-19, impaired hand grip strength was found in 24.4% for the right hand and 23.1% for the left hand. Walking speed, functional mobility, and postural control were found to be impaired in 29.5%, 21.8%, and 5.1%, respectively. For impaired walking speed, longer length of stay at intensive care unit and presence of diabetes mellitus were risk factors. Diabetes mellitus was found to be the risk factor for impaired functional mobility. Conclusion In this study, 45% of the participants showed impairment in function, activity capacity or both. These results suggest that individuals who recovered after intensive care unit admission for COVID-19 would benefit from receiving long-term follow-up to enable identification of those with need of physical health assistance and rehabilitation.
