“…These results, togheter with biases found in the breath‐by‐breath inspiratory and expiratory phase durations values (up to 0.15 seconds), are similar to values reported in previous studies adopting fiber optic‐based garments for the breathing rate monitoring . In addition, the f R estimation show that results herein reported are similar to those shown in a previous paper focused on the smart textile under test.…”

“…In fact, from a physiological point of view, the chest wall can be considered as a 6‐compartmental structure, composed by right and left sides of the pulmonary rib cage, the abdominal rib cage, and the abdomen that reflect anatomical and muscular districts working during the breathing activity . Motion capture (MoCap) systems have been extensively used on patients and athletes to investigate how the breathing biomechanics is influenced by postures, activities, diseases. These systems require the positioning of photo‐reflective markers attached on the skin , the adoption of dedicated computational methods together with high‐speed infra‐red (IR) cameras.…”

“…These systems require the positioning of photo‐reflective markers attached on the skin , the adoption of dedicated computational methods together with high‐speed infra‐red (IR) cameras. However, the high costs of cameras, the need of dedicated equipped room, professional staff required for pre‐ and post‐processing phase, strongly limit the use of MoCap systems especially for prolonged monitoring .…”

The use of wearable systems for monitoring vital parameters has gained wide popularity in several medical fields. The focus of the present study is the experimental assessment of a smart textile based on 12 fiber Bragg grating sensors for breathing monitoring and thoraco-abdominal motion pattern analysis. The feasibility of the smart textile for monitoring several temporal respiratory parameters (ie, breath-by-breath respiratory period, breathing frequency, duration of inspiratory and expiratory phases), volume variations of the whole chest wall and of its compartments is performed on 8 healthy male volunteers. Values gathered by the textile are compared to the data obtained by a motion analysis system, used as the reference instrument. Good agreement between the 2 systems on both respiratory period (bias of 0.01 seconds), breathing frequency (bias of -0.02 breaths/min) and tidal volume (bias of 0.09 L) values is demonstrated. Smart textile shows good performance in the monitoring of thoraco-abdominal pattern and its variation, as well.

Background Chronic obstructive pulmonary disease (COPD) leads to peripheral and respiratory muscle dysfunctions. Nowadays, inspiratory muscle training can be geared toward strength or endurance gains. This study aims to investigate the effects of an inspiratory muscle training (IMT) protocol using different therapeutic modalities to be implemented in pulmonary rehabilitation programs. The effects of IMT on exercise capacity were considered as the primary endpoint, and the effects of IMT on inspiratory muscle function, health-related quality of life, and daily physical activity level were considered as the secondary outcomes. Methods This study is a blinded-investigator randomized controlled clinical trial. Sixty subjects will be randomly allocated into three groups: (1) pulmonary rehabilitation (PR) associated with inspiratory muscle training without any load (PRWIMT), (2) PR associated with inspiratory muscle training with a linear load (PRIMTLL), and (3) PR associated with inspiratory muscle training with isocapnic voluntary hyperpnea (PRIMTIVH). The protocol will be performed 5 days a week (3 days with supervision) for 10 weeks. The study will assess anthropometric data, lung function, respiratory muscle strength, and functional capacity by the Incremental Shuttle Walking Test and the Six-Minute Walk Test, lung volumes during the submaximal endurance test, peripheral muscle strength of the upper and lower limbs, dyspnea, and quality of life related to health, before and after the training protocol. Normality will be tested using the Kolmogorov-Smirnov test, and variables will be compared by two-way analysis of variance. The significance level was set at p < 0.05. Ethics approval was obtained from the Institutional Ethics Committee in Research (1.663.411). The study results will be disseminated through presentation at specific scientific conferences and publication in peer-reviewed journals. Discussion The different IMT protocols used in our study will be able to guide respiratory therapists to understand and to include in conventional PR programs the most effective respiratory muscle training type in subjects with COPD.

“…However, the literature still lacks evidence to demonstrate which technique is superior when used alone, as well as whether the combination of techniques is effective in increasing volume variations of the CW evaluated by optoelectronic plethysmography (OEP). It is important to emphasize that the OEP is a device with good accuracy that provides valid and reliable measures of CW volumes and its compartments, as previously described [ 12 ]. The present study is also justified by the physiological importance of the response to increased pulmonary expandability in the prevention and treatment of several lung diseases that evolve with a restrictive respiratory pattern.…”

Acute effects of three pulmonary reexpansion modalities on thoracoabdominal motion of healthy subjects: Randomized crossover study

et al. 2019

BackgroundChest physiotherapy can be an alternative to increase lung volumes through pulmonary expansion therapies, but there is still inconsistency in the literature in order to determine which device can promote a greater volume increase at the expense of a better ventilatory pattern. Therefore, the aim of this study was to evaluate and compare the chest wall kinematics of healthy subjects submitted to the use of three different devices for pulmonary reexpansion.MethodsChest wall compartmental and operational volumes, breathing pattern and thoracoabdominal asynchrony were evaluated in 12 healthy individuals through optoelectronic plethysmography during quiet breathing, pulmonary reexpansion and recovery. Three different devices (volume-oriented incentive spirometer–IS-v; positive expiratory pressure–PEP; and incentive spirometer volume and pressure oriented–IS-vp) were administered in a random order with at least 48h between the devices.ResultsA greater volume variation in the chest wall and its compartments was observed when the IS-vp was used in comparison with the other devices (p<0.05). Furthermore, the IS-vp mobilizes a greater amount of volume accompanied by greater synchronism between the compartments when compared to IS-v (p <0.05).ConclusionThe IS-vp may be able to increase total and compartmental chest wall volumes, as well as improve synchrony among compartments when compared to IS-v and PEP devices, thus constituting an important tool for treating patients with restrictive ventilatory pattern.
