Background The impact of COVID-19 on physical and mental health and employment after
hospitalisation with acute disease is not well understood. The aim of this study was to …

Background Breathlessness is a common and distressing symptom, which increases in
many diseases as they progress and is difficult to manage. We assessed the effectiveness of …

Background: Quadriceps weakness and loss of muscle mass predict mortality in chronic
obstructive pulmonary disease (COPD). It was hypothesised that a reduced quadriceps cross-…

Background Exacerbations of chronic obstructive pulmonary disease (COPD) are
characterised by increased dyspnoea, reduced quality of life and muscle weakness. Re-exacerbation …

Background: Respiratory muscle weakness is an important clinical problem. Tests of varying
complexity and invasiveness are available to assess respiratory muscle strength. The …

Background A standardised approach to assessing COVID-19 survivors has not been
established, largely due to the paucity of data on medium- and long-term sequelae. Interval chest …

The aim of the present study was to use the diaphragm electromyogram (EMG di ) to
compare levels of neural respiratory drive (NRD) in a cohort of healthy subjects and chronic …

Background: The load imposed on ventilation by increased body mass contributes to the
respiratory symptoms caused by obesity. A study was conducted to quantify ventilatory load and …

Background Neural respiratory drive (NRD) measured from the diaphragm electromyogram (EMGdi)
reflects the load/capacity balance of the respiratory muscle pump and is a marker of …

The aim of this study was to test the hypothesis that neural respiratory drive, measured using
diaphragm electromyogram (EMG di ) activity expressed as a percentage of maximum (…
