“…Regarding the physical assessment of patients with asthma, spirometry parameters seem to be commonly used in order to evaluate the airways alterations 5. Indeed, the forced expiratory volume in one second (FEV 1 ), forced vital capacity (FVC) and FEV 1 /FVC relationship seem to be commonly considered as the most used spirometry parameters to predict physiological measurements in patients with asthma 6.…”

Purpose: Based on the possible association between reduced foot dorsiflexion and high risk of falls, the main objective was to determine the ankle and 1º metatarsophalangeal joint (1 st MTTP) dorsiflexion range of motion and falls rate in patients with asthma compared to healthy matched-paired controls. Methods: A case-control study was carried out. Eighty participants were recruited and divided into patients with asthma (case group; n=40) and matched-paired healthy participants (control group; n=40). Foot dorsal flexion range of motion (assessed by the Weight-Bearing Lunge Test [WBLT]) and falls rate (evaluated as falls number during the prior year) were considered as the primary outcomes. Indeed, ankle dorsiflexion was measured by a mobile app (º) and a tape measure (cm) as well as 1 st MTTP dorsiflexion was determined by and universal goniometer (º). Results: Statistically significant differences ( P <.05) showed that patients with asthma presented a greater falls rate than healthy participants and reduced bilateral ankle and 1 st MTTP dorsiflexion ranges of motion than healthy participants, except for the left ankle dorsiflexion measured as degrees ( P >.05). Conclusions: These study findings showed that a falls rate increase and bilateral foot dorsal flexion limitations of the ankle and 1 st MTTP joints are exhibited in patients who suffer from asthma.

“…As for the spirometry parameters, the FEV 1 /FVC parameter showed lower values in asthma patients than in healthy subjects based on physiological alterations and airways impairment reported in previous research studies of asthma patients [5,6]. Although patients diagnosed with asthma or allergic asthma were included based on an experienced allergists’ diagnosis, considering the typical clinical symptomatology of asthma diagnosis, as well as a positive lung function bronchodilator test with the FEV 1 parameter higher than 200 mL and 12% values with respect to baseline measurements [5,6]. The case group included individuals who had been prescribed bronchodilators interventions by their allergists.…”

“…Spirometry parameters were assessed by an experienced and specialist allergist to determine the airways flow restriction used the Datospir-600 Touch tool (software from SIBELMED e-20; Rosselló, 08026 Barcelona, Spain) [5]. FVC, FEV 1 , and FEV 1 /FVC parameters were measured as percentages (%) since these values are considered among the most useful spirometer values for physiological measurements prediction in patients diagnosed with asthma [6]. These values reflected lung function and were previously correlated with an r of 0.747 for chest wall expansion [31].…”

“…Lung function may be assessed by means of spirometry [5]. The most frequent used spirometry parameters in patients diagnosed with asthma may be the forced expiratory volume during 1 s (FEV 1 ) and the forced vital capacity (FVC), as well as the FEV 1 /FVC coefficient due to reflect airway alterations and the prediction of physiological measurements [6].…”

Background: Based on changes in lung function and musculoskeletal disorders in patients with asthma, this study aimed to compare the tarsal tunnel and fibular bone pressure pain thresholds (PPTs) of patients with asthma and healthy matched-paired controls. Methods: A case-control study was performed. One hundred participants were recruited: 50 asthma patients and 50 healthy matched-paired controls. Bilaterally, tarsal tunnel and fibula bone PPTs were registered. Results: Statistically significant differences (p < 0.01) were shown bilaterally for tarsal tunnel PPT. With the exception of fibula PPT (p > 0.05), asthma patients presented less tarsal tunnel PPT than healthy participants. Statistically significant differences (p < 0.05) were shown for two linear regression prediction models of the right (R2 = 0.279) and left (R2 = 0.249) tarsal tunnels PPTs as dependent variables, and based on sex, group, contralateral tarsal tunnel PPT and ipsilateral fibula PPT as independent variables. Conclusions: The study findings showed that a bilateral tarsal tunnel mechanosensitivity increase is exhibited in patients diagnosed with asthma. The presence of asthma may bilaterally predict the PPT of tarsal tunnel. These findings may suggest the presence of central sensitization in asthma patients, which could clinically predispose them to musculoskeletal disorders, such as tarsal tunnel syndrome.

The spirometry is considered a preclinical tool for the evaluation of the respiratory system. The formal lung volumes measurement and health status lung system are made using spirometry. Artificial neural network (ANN) has been introduced in solving complex problems in a large number of different settings, including medical diagnosis support system as predictive power. An objective of this research was intended to investigate the development of a new decision support system (DSS) using ANN modeling approaches and algorithms to predict pulmonary function in people. The spirometry data and general characteristics, anthropometric data, and body composition parameters (N = 130) were obtained from subjects. The classification of pulmonary function was performed by the multi-layer perceptron (MLP) model. Findings show that the MLP model is capable of classifying respiratory abnormalities in different people. The ANN model was totally 93.6%, 92.3%, 84.6%, and 91.5% successful in correctly classified in training, validation, test, and all data, respectively. Also, a DSS tool was created that allows the evaluation and classification of the results of spirometry data. It appears that ANNs are useful in classification pulmonary function.
