Function Tests

The main elements of a chest assessment are outlined. Elementary measurements which should be taken by physiotherapists are described. Simple lung function tests which are within the capability of physiotherapists who are closely concerned with chest patients are explained in some detail. The tests concerned are: Peak Expiratory Flow Rate, Forced Vital Capacity, Forced Expiratory Volume in 1 sec. and the ratio Forced Expiratory Volume in 1 sec./Forced Vital Capacity as a percentage. Four of the more advanced tests and their underlying concepts which are more the domain of special pulmonary testing laboratories are briefly described.

The Relationship

1. As marked lability of bronchial obstruction is a risk factor for asthma severity, it may influence dyspnoea, the most common subjective complaint in asthma. We therefore studied the relationship between spontaneous dyspnoea and the degree of bronchial lability, as assessed by the daily variability in peak expiratory flow rate and the bronchial responsiveness to either carbachol or salbutamol, in 33 stable symptomatic asthmatic patients. 2. Three times daily, for 10 consecutive days, the patients rated the intensity of their dyspnoea on a visual analogue scale and immediately afterwards recorded their peak expiratory flow rate. Within the next 5 days, we determined the bronchial response by measuring the forced expiratory volume in 1 s and the specific resistance of airways to either carbachol or salbutamol according to baseline airway obstruction. 3. We characterized dyspnoea for each patient by using two parameters: (1) the relationship with underlying airway obstruction, as assessed by the correlation coefficient r between dyspnoea scores and corresponding values of peak expiratory flow rate (r DSc-PEFR), and (2) the intensity, as assessed by the mean visual analogue scale dyspnoea score adjusted for comparable airway obstruction. Bronchial lability was characterized by (1) variability in mean daily peak expiratory flow rate and (2) bronchial responsiveness to either carbachol (as assessed by the threshold dose and the slope of the dose-response curve) or salbutamol (as assessed by the threshold dose and maximal response). We assessed the relationship between dyspnoea and bronchial lability by correlating each of their respective characteristics. 4. We found large inter-subject differences in both characteristics of dyspnoea, r DSc-PEFR was unrelated to variability in mean daily peak expiratory flow rate and to all characteristics of bronchial responsiveness used, except for maximal salbutamol-induced increase in forced expiratory volume in 1 s (as a percentage of predicted). Adjusted visual analogue scale dyspnoea scores were unrelated to all characteristics of bronchial lability. 5. Our results suggest that spontaneous dyspnoea, as characterized by its intensity at comparable levels of airway obstruction and by its relationship with underlying airway obstruction, is poorly related to the degree of bronchial lability in stable symptomatic asthmatic patients.

Background:Despite the common use of braces to prevent curve progression in idiopathic scoliosis, their functional effects on respiratory mechanics have not been widely studied.Objective:The objective was to determine the effects of bracing on pulmonary function in idiopathic scoliosis.Methods:A total of 27 adolescents with a mean age of 14.5 ± 1.5 years and idiopathic scoliosis were included in the study. Pulmonary function evaluation included vital capacity, forced expiratory volume, forced vital capacity, maximum ventilator volume, peak expiratory flow, and respiratory muscle strengths, measured with a spirometer, and patient-reported degree of dyspnea. The tests were performed once prior to bracing and at 1 month after bracing (while the patients wore the brace).Results:Compared with the unbraced condition, vital capacity, forced expiratory volume, forced vital capacity, maximum ventilator volume, and peak expiratory flow values decreased and dyspnea increased in the braced condition. Respiratory muscle strength was under the norm in both unbraced and braced conditions, while no significant difference was found for these parameters between the two conditions.Conclusion:The spinal brace for idiopathic scoliosis tended to reduce pulmonary functions and increase dyspnea symptoms (when wearing a brace) in this study. Special attention should be paid in-brace effects on pulmonary functions in idiopathic scoliosis.Clinical relevanceBracing seems to mimic restrictive pulmonary disease, although there is no actual disease when the brace is removed. This study suggests that bracing may result in a deterioration of pulmonary function when adolescents with idiopathic scoliosis are wearing a brace.
