“…Our findings were in line with those of previous studies, 2,8,9,26,27 which have shown that females have a wider rib cage and lower abdominal contributions to tidal volume than males during quiet breathing. However, in multiple models there were no significant relationships between breathing movement during quiet breathing in the supine position and sex.…”

BACKGROUND: Physical assessment of breathing is an important component of physical therapy evaluations. However, there are no standardized reference values of breathing movements available for use in clinical practice. The purpose of this study was to determine the 3-dimensional distances of observational points on the thorax and abdomen during breathing in healthy subjects and to assess the effects of age, posture, and sex on breathing movements. METHODS: We studied the 3-dimensional breathing movement distances of the thorax and abdomen in 100 healthy subjects (50 males, 50 females). Breathing movements were measured with a 3-dimensional motion system during quiet and deep breathing with subjects in supine and sitting positions. Thirteen reflective markers were placed on the upper (the clavicles, 3rd ribs, and sternal angle) and lower thorax (the 8th ribs, 10th ribs, and xiphoid process) and the abdomen (upper abdomen and lateral abdomen). Range of movement in both breathing conditions was measured as the 3-dimensional distance at half respiratory cycle. Respiratory rates were calculated based on the breathing movements analyzed. One-way analysis of variance, t tests, and multiple regression were used for statistical analysis. RESULTS: The average marker distances for the thorax and abdomen during quiet breathing were less than one third of those during deep breathing. Upper thoracic movement was significantly decreased with age. There was less abdominal movement in females than in males, except during quiet breathing in the supine position. The distances between the thoracic markers were greater and those of the abdomen were less during quiet and deep breathing in the sitting position, compared with those in the supine position. CONCLUSIONS: We found that the observed breathing movements were related to the effects of age, sex, and posture. These findings are in agreement with those reported in previous studies. The results may be helpful in assessing breathing movement by physical examination.

“…Although phonation and, in turn, the production of speech, can be changed by lung disease, no references in the specialized literature have been observed (7,8) . Thus, the aim of this study was to correlate the measurement of maximum phonation time with the volume of air which can be exhaled from the lungs in the first second and compare maximum phonation time, emission of /s/, /z/ and 's"/"z" ratio in healthy individuals and individuals with chronic obstructive pulmonary disease.…”

“…Oral communication is the means by which the individual relates experiences, ideas, knowledge and feelings and the individual with COPD may have difficulty communicating because phonation tasks impose considerable respiratory requirements for the performance of speech, both in terms of expiratory flow and excursions of expiration lung volume (7) . Despite the understanding that phonation can be altered by lung disease, there is no scientific evidence of objective measures and little phonatory evidence in routine clinical evaluation of patients with COPD (8) .…”

Purpose: This study correlates the extent of maximum phonation time (MPT) with the volume of air exhaled in the first second pulmonary (FEV 1 ) and compares the MPT emission of /s/, /z/ and s/z ratio in healthy subjects and those with chronic obstructive pulmonary disease (COPD). Methods:We studied 14 normal volunteers (control group), mean age 65 years, and 16 patients with COPD, mean age 68 years. The diagnosis of

“…However, physical examinations are not quantitative and depend on the experience of the assessor. Although precision measurement equipment such as a magnetometers 1) , respiratory inductive plethysmography 2) , optoelectronic plethysmography [3][4][5][6][7] , and respiratory movement measuring instrument 8) can be used for quantitative measurements, these devices are unsuitable for clinical practice because of their high cost and complexity. Therefore, a breathing movement scale that assesses five levels of breathing movements of the chest and abdominal wall by physical examination was developed.…”

Abstract.[Purpose] The purpose of this study was to test the reliability and validity of a breathing movement measuring device (BMMD) that was newly developed for the objective assessment of breathing movements in clinical practice. [Subjects and Methods] The breathing movement distances of the chest (bilateral third and eighth ribs) and abdomen (upper abdomen) of 30 healthy young males were measured using the BMMD and a threedimensional (3D) motion analysis system during quiet breathing. During measurements, the pen-size mechanical BMMD was held in the hand and placed on selected observation points. Distances on the BMMD scale were read by two raters. In addition, the breathing movement distances of 10 subjects were measured during quiet breathing using the BMMD fixed on a tripod. The distances between the reflective markers on the observation points were measured. The intraclass correlation coefficient, Bland-Altman analysis, and Pearson's correlation coefficient were performed.[Results] The inter-rater reliability of the BMMD was low-to-moderate. However, the reliability and validity between the two measurement methods were high. Systematic errors were identified for almost all the observation points.[Conclusion] The reliability and validity of the BMMD, which works by comparing the reflective marker distances, were acceptable. These findings suggest that the BMMD may be useful for quantitatively assessing chest and abdominal wall movements during quiet breathing in clinical practice.

Breathing pattern and kinematics in normal subjects during speech, singing and loud whispering

Abstract: Physical characteristics have a greater importance than gender in determining breathing pattern and chest wall kinematics during phonation. The activity of the control of expiration during phonation is more complex than during exercise.
