OBJECTIVE To evaluate sarcopenic indices in relation to respiratory muscle strength (RMS) in elderly people. METHODS This study included 65 volunteers over the age of 60 (30 men and 35 women). The skeletal muscle mass index (SMI) was measured using bioimpedance analysis. Limb muscle function was assessed by handgrip strength (HGS), the Short Physical Performance Battery (SPPB), and gait speed...

BACKGROUND It has been known for many years that there are variations between asthmatic patients in terms of their perception of breathlessness during airway obstruction. STUDY OBJECTIVE To investigate the relationship between beta(2)-agonist consumption and the score of perception of dyspnea, in mild asthmatics, and the relationship between the effect of specific inspiratory muscle training ...

We investigated (1) the relationship between the baseline and inspiratory muscle training (IMT) induced increase in maximal inspiratory pressure (P(I,max)) and (2) the relative contributions of the inspiratory chest wall muscles and the diaphragm (P(oes)/P(di)) to P(I,max) prior to and following-IMT. Experiment 1: P(I,max) was assessed during a Müeller manoeuvre before and after 4-wk IMT (n=30)...

Background Maximal inspiratory pressure (MIP) is used to assess respiratory muscle strength of patients with myasthenia gravis (MG) requiring ventilatory support. Electrical activity of the diaphragm (E-di) has been used to guide weaning. Case presentation The MIP and tidal volume/ΔE-di (the patient-to-ventilator breath contribution) were monitored in a 12-year-old girl with MG requiring vent...

that the authors never used a flanged mouthpiece nor did they make their PI,max measurements from functional residual capacity but rather from residual volume. The type of mouthpiece and the way it is used result in large pressure differences obtained during the measurements of PI,max and PE,max [5]. Lung volumes also affect these measurements and appropriate reference values should be used [6]...

OBJECTIVE To investigate the relationships between respiratory muscle strength and conventional sarcopenic indices such as skeletal muscle mass and limb muscle strength. METHODS Eighty-nine young adult volunteers who had no history of medical or musculoskeletal disease were enrolled. Skeletal muscle mass was measured by bioelectrical impedance analysis and expressed as a skeletal muscle mass ...

[Purpose] Counteracting the systemic cytokine release and its inflammatory effects by improving respiratory muscle strength and controlling lung inflammation may be important for improving immune system in patients with chronic obstructive pulmonary disease, So the aim of the present study was to evaluate the effect of low level laser therapy and inspiratory muscle training on interleukin-6 (IL...

We studied 53 patients with proximal myopathy to determine at what level of muscle weakness hypercapnic respiratory failure is likely, and which tests of pulmonary function or respiratory muscle strength would best suggest this development. Respiratory muscle strength was determined from maximal static efforts and in half the patients, both inspiratory and expiratory muscle strengths were less ...

OBJECTIVE The objective of this study was to evaluate and correlate inspiratory muscle strength using maximal inspiratory pressure (MIP) and sniff nasal inspiratory pressure (Pnsn) in patients with coronary artery disease in pre- and postoperative of myocardial revascularization surgery. METHODS Thirty-eight men were studied, divided into a control group (CG) comprised of healthy individuals ...
