One hundred and seventy one patients with primary pneumonia entered a single blind, placebo controlled trial of physiotherapy. Treatment was allocated at random, physiotherapy consisting of postural drainage, external help with breathing, percussion, and vibration and the controls receiving advice on expectoration, deep breathing, and how to exercise to avoid thrombosis. Principles of pharmaceutical management were the same in the two groups. There was no objective evidence that daily physiotherapy helped during the acute phase of the disease. On the contrary, in younger patients, smokers, and patients with interstitial pneumonia physiotherapy appeared to prolong the duration of fever as well as the hospital stay. It is concluded that chest physiotherapy is at best useless in patients with primary infectious pneumonia. We undertook a randomized clinical trial to evaluate the efficacy of chest physiotherapy and intermittent positive-pressure breathing in the treatment of pneumonia. The diagnosis of pneumonia required a compatible clinical history and x-ray confirmation. A total of 54 patients were assigned to treatment and control groups and were similar in age, smoking history, underlying lung disease and prior antibiotic treatment. Antibiotic therapy, guided by Gram stain and sputum and blood cultures, was similar in both groups. Chest physiotherapy, consisting of postural drainage, percussion and vibration, was given concurrently with intermittent positive-pressure breathing with use of racemic epinephrine every four hours. There was no statistically significant difference in duration of fever, extent of radiographic clearing, duration of hospital stay and mortality between the control and treated groups. Chest physiotherapy and intermittent positive-pressure breathing do not hasten the resolution of pneumonia. To evaluate the benefits of conventional chest physiotherapy in acute bronchiolitis, 32 patients were allocated in a randomized controlled trial, 16 were given twice daily chest physiotherapy compared with 16 controls who were not given chest physiotherapy. The treatment group showed a mean clinical score for respiratory disability at admission of 5.56 (+/- 1.96), and 3.25 (+/- 1.27) when discharged. The control group presented a score of 5.75 (+/- 1.61) and 3.12 (+/- 1.30), p=0.77 and p=0.76 respectively. The mean length of illness in hospital in the treatment group was 4.00 (+/- 2.00) vs 3.87 (+/- 1.30) in the control group, p=0.84. Chest physiotherapy does not produce clinically important benefits in the treatment of acute bronchiolitis. Forty four children with acute bronchiolitis were given twice daily chest physiotherapy in addition to standard supportive measures and were compared with 46 controls who were not given physiotherapy. There was no clinically discernable benefit on the course of their illness. Acute bronchiolitis treatment in children and infants is largely supportive, but chest physiotherapy is routinely performed in some countries. In France, national guidelines recommend a specific type of physiotherapy combining the increased exhalation technique (IET) and assisted cough (AC). Our objective was to evaluate the efficacy of chest physiotherapy (IET + AC) in previously healthy infants hospitalized for a first episode of acute bronchiolitis.
                We conducted a multicenter, randomized, outcome assessor-blind and parent-blind trial in seven French pediatric departments. We recruited 496 infants hospitalized for first-episode acute bronchiolitis between October 2004 and January 2008. Patients were randomly allocated to receive from physiotherapists three times a day, either IET + AC (intervention group, n=246) or nasal suction (NS, control group, n=250). Only physiotherapists were aware of the allocation group of the infant. The primary outcome was time to recovery, defined as 8 hours without oxygen supplementation associated with minimal or no chest recession, and ingesting more than two-thirds of daily food requirements. Secondary outcomes were intensive care unit admissions, artificial ventilation, antibiotic treatment, description of side effects during procedures, and parental perception of comfort. Statistical analysis was performed on an intent-to-treat basis. Median time to recovery was 2.31 days, (95% confidence interval [CI] 1.97-2.73) for the control group and 2.02 days (95% CI 1.96-2.34) for the intervention group, indicating no significant effect of physiotherapy (hazard ratio [HR]=1.09, 95% CI 0.91-1.31, p=0.33). No treatment by age interaction was found (p=0.97). Frequency of vomiting and transient respiratory destabilization was higher in the IET + AC group during the procedure (relative risk [RR]=10.2, 95% CI 1.3-78.8, p=0.005 and RR=5.4, 95% CI 1.6-18.4, p=0.002, respectively). No difference between groups in bradycardia with or without desaturation (RR=1.0, 95% CI 0.2-5.0, p=1.00 and RR=3.6, 95% CI 0.7-16.9, p=0.10, respectively) was found during the procedure. Parents reported that the procedure was more arduous in the group treated with IET (mean difference=0.88, 95% CI 0.33-1.44, p=0.002), whereas there was no difference regarding the assessment of the child's comfort between both groups (mean difference=-0.07, 95% CI -0.53 to 0.38, p=0.40). No evidence of differences between groups in intensive care admission (RR=0.7, 95% CI 0.3-1.8, p=0.62), ventilatory support (RR=2.5, 95% CI 0.5-13.0, p=0.29), and antibiotic treatment (RR=1.0, 95% CI 0.7-1.3, p=1.00) was observed.
                IET + AC had no significant effect on time to recovery in this group of hospitalized infants with bronchiolitis. Additional studies are required to explore the effect of chest physiotherapy on ambulatory populations and for infants without a history of atopy.
                ClinicalTrials.gov NCT00125450. Chest physiotherapy is essential to the management of cystic fibrosis (CF). However, respiratory muscle fatigue and oxygen desaturation during treatment have been reported. The aim of this study was to determine whether non-invasive ventilation (NIV) during chest physiotherapy could prevent these adverse effects in adults with exacerbations of CF.
                Twenty six patients of mean (SD) age 27 (6) years and forced expiratory volume in 1 second (FEV1) 34 (12)% predicted completed a randomised crossover trial comparing standard treatment (active cycle of breathing technique, ACBT) with ACBT + NIV. Respiratory muscle strength (PImax, PEmax), spirometric parameters, and dyspnoea were measured before and after treatment. Pulse oximetry (SpO2) was recorded during treatment. Sputum production during treatment and 4 and 24 hours after treatment was evaluated.
                There was a significant reduction in PImax following standard treatment that was correlated with baseline PImax (r=0.73, p<0.001). PImax was maintained following NIV (mean difference from standard treatment 9.04 cm H2O, 95% confidence interval (CI) 4.25 to 13.83 cm H2O, p=0.006). A significant increase in PEmax was observed following the NIV session (8.04 cm H2O, 95% CI 0.61 to 15.46 cm H2O, p=0.02). The proportion of treatment time with SpO2 < or =90% was correlated with FEV1 (r=-0.65, p<0.001). NIV improved mean SpO2 (p<0.001) and reduced dyspnoea (p=0.02). There were no differences in FEV1, forced vital capacity (FVC) or sputum weight, but FEF(25-75) increased following NIV (p=0.006).
                Reduced inspiratory muscle strength and oxygen desaturation during chest physiotherapy are associated with inspiratory muscle weakness and severity of lung disease in adults with exacerbations of CF. Addition of NIV improves inspiratory muscle function, oxygen saturation and small airway function and reduces dyspnoea. The aim of our study was to compare the short-term efficacy of three different chest physiotherapy (CPT) regimens (PD, postural drainage; PEP, positive expiratory pressure physiotherapy; HFCC, high-frequency chest compression physiotherapy) on patients with cystic fibrosis (CF) hospitalized for an acute pulmonary exacerbation. Sixteen patients with CF, 8 males, 8 females, aged 15-27 years (mean, 20.3 +/- 4), met the inclusion criteria: 1) age over 14 years; 2) mild or moderate airway obstruction; 3) sputum volume > 30 mL/day; 4) being proficient in PD and PEP CPT. Patients at admission had (mean +/- SD) forced volume in 1 second (FEV1) 52.2 +/- 21.9 percent predicted; Shwachman-Kulczycki clinical score 65.1 +/- 11 points; Chrispin-Norman chest radiography score 18.6 +/- 4.3 points. The three CPT regimens and a control-treatment (CONT) were administered in a random sequence, each patient receiving each treatment twice a day (in 50 minute sessions) for 2 consecutive days. During CONT and for 30 minutes after each session only spontaneous coughing was allowed. Wet and dry weight of sputum were recorded during the 50-minute sessions and 30 minutes afterward. Lung function was measured before and 30 minutes after each session. For each treatment a score was given by the patient for efficacy, and by both the patient and the physiotherapist for tolerance. Wet and dry weights of sputum collected during the sessions were greater for all CPT regimens than for CONT (P < 0.001, P < 0.0001). No significant differences between the three CPT regimens for both wet and dry weights were found when the number of coughs was taken into account.(ABSTRACT TRUNCATED AT 250 WORDS) Regular chest physiotherapy is advocated in non-cystic fibrosis bronchiectasis despite little evidence supporting its routine use. This study aimed to establish the efficacy of regular chest physiotherapy in non-cystic fibrosis bronchiectasis compared with no regular chest physiotherapy. 20 patients not practising regular chest physiotherapy were enrolled in a randomised crossover trial of 3 months of twice daily chest physiotherapy using an oscillatory positive expiratory pressure device compared with 3 months of no chest physiotherapy. The primary end-point was the Leicester Cough Questionnaire (LCQ). Additional outcomes included 24-h sputum volume, forced expiratory volume in 1 s (FEV(1)), forced vital capacity (FVC), forced expiratory flow at 25-75% of FVC (FEF(25-75%)), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), exercise capacity, sputum microbiology and St George's Respiratory Questionnaire (SGRQ). The treatment effect was estimated using the differences of the pairs of observations from each patient. There was a significant improvement in all domains and total LCQ score with regular chest physiotherapy (median (interquartile range) total score improvement 1.3 (-0.17-3.25) units; p = 0.002). 24-h sputum volume increased significantly with regular chest physiotherapy (2 (0-6) mL; p = 0.02), as did exercise capacity (40 (15-80) m; p = 0.001) and SGRQ total score (7.77 (-0.99-14.5) unit improvement; p = 0.004). No significant differences were seen in sputum bacteriology, FEV(1), FVC, FEF(25-75%), MIP or MEP. Regular chest physiotherapy in non-cystic fibrosis bronchiectasis has small, but significant benefits. Patients aged over 45 admitted to hospital with exacerbations of chronic bronchitis alone or in association with cor pulmonale, pneumonia, or respiratory failure were placed in one of three groups (men with hypoxia, men without hypoxia, and women). Patients within these groups were then randomly allocated to receive either standard drug treatment alone or standard drug treatment plus intermittent positive-pressure ventilation (IPPV). No significant differences occurred between the controls and patients receiving physiotherapy and IPPV in any group. We conclude that when a patient with chronic bronchitis and respiratory failure is deteriorating emphasis should be on correct diagnosis, fluid electrolyte balance, and nutrition together with oxygen treatment when necessary, rather than on additional physiotherapy.
Based on current limited evidence, chest physiotherapy might not be recommended as routine additional treatment for pneumonia in adults.
