Abstract
BACKGROUND Cystic fibrosis (CF) is an inherited life-limiting disorder. Over time persistent infection and inflammation within the lungs contribute to severe airway damage and loss of respiratory function. Chest physiotherapy, or airway clearance techniques (ACTs), are integral in removing airway secretions and initiated shortly after CF diagnosis. Conventional chest physiotherapy (CCPT) generally requires assistance, while alternative ACTs can be self-administered, facilitating independence and flexibility. This is an updated review. OBJECTIVES To evaluate the effectiveness (in terms of respiratory function, respiratory exacerbations, exercise capacity) and acceptability (in terms of individual preference, adherence, quality of life) of CCPT for people with CF compared to alternative ACTs. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search was 26 June 2022. SELECTION CRITERIA We included randomised or quasi-randomised controlled trials (including cross-over design) lasting at least seven days and comparing CCPT with alternative ACTs in people with CF. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our primary outcomes were 1. pulmonary function tests and 2. number of respiratory exacerbations per year. Our secondary outcomes were 3. quality of life, 4. adherence to therapy, 5. cost-benefit analysis, 6. objective change in exercise capacity, 7. additional lung function tests, 8. ventilation scanning, 9. blood oxygen levels, 10. nutritional status, 11. mortality, 12. mucus transport rate and 13. mucus wet or dry weight. We reported outcomes as short-term (seven to 20 days), medium-term (more than 20 days to up to one year) and long-term (over one year). MAIN RESULTS We included 21 studies (778 participants) comprising seven short-term, eight medium-term and six long-term studies. Studies were conducted in the USA (10), Canada (five), Australia (two), the UK (two), Denmark (one) and Italy (one) with a median of 23 participants per study (range 13 to 166). Participant ages ranged from newborns to 45 years; most studies only recruited children and young people. Sixteen studies reported the sex of participants (375 males; 296 females). Most studies compared modifications of CCPT with a single comparator, but two studies compared three interventions and another compared four interventions. The interventions varied in the duration of treatments, times per day and periods of comparison making meta-analysis challenging. All evidence was very low certainty. Nineteen studies reported the primary outcomes forced expiratory volume in one second (FEV1)and forced vital capacity (FVC), and found no difference in change from baseline in FEV1 % predicted or rate of decline between groups for either measure. Most studies suggested equivalence between CCPT and alternative ACTs, including positive expiratory pressure (PEP), extrapulmonary mechanical percussion, active cycle of breathing technique (ACBT), oscillating PEP devices (O-PEP), autogenic drainage (AD) and exercise. Where single studies suggested superiority of one ACT, these findings were not corroborated in similar studies; pooled data generally concluded that effects of CCPT were comparable to those of alternative ACTs. CCPT versus PEP We are uncertain whether CCPT improves lung function or has an impact on the number of respiratory exacerbations per year compared with PEP (both very low-certainty evidence). There were no analysable data for our secondary outcomes, but many studies provided favourable narrative reports on the independence achieved with PEP mask therapy. CCPT versus extrapulmonary mechanical percussion We are uncertain whether CCPT improves lung function compared with extrapulmonary mechanical percussions (very low-certainty evidence). The annual rate of decline in average forced expiratory flow between 25% and 75% of FVC (FEF25-75) was greater with high-frequency chest compression compared to CCPT in medium- to long-term studies, but there was no difference in any other outcome. CCPT versus ACBT We are uncertain whether CCPT improves lung function compared to ACBT (very low-certainty evidence). Annual decline in FEF25-75 was worse in participants using the FET component of ACBT only (mean difference (MD) 6.00, 95% confidence interval (CI) 0.55 to 11.45; 1 study, 63 participants; very low-certainty evidence). One short-term study reported that directed coughing was as effective as CCPT for all lung function outcomes, but with no analysable data. One study found no difference in hospital admissions and days in hospital for exacerbations. CCPT versus O-PEP We are uncertain whether CCPT improves lung function compared to O-PEP devices (Flutter device and intrapulmonary percussive ventilation); however, only one study provided analysable data (very low-certainty evidence). No study reported data for number of exacerbations. There was no difference in results for number of days in hospital for an exacerbation, number of hospital admissions and number of days of intravenous antibiotics; this was also true for other secondary outcomes. CCPT versus AD We are uncertain whether CCPT improves lung function compared to AD (very low-certainty evidence). No studies reported the number of exacerbations per year; however, one study reported more hospital admissions for exacerbations in the CCPT group (MD 0.24, 95% CI 0.06 to 0.42; 33 participants). One study provided a narrative report of a preference for AD. CCPT versus exercise We are uncertain whether CCPT improves lung function compared to exercise (very low-certainty evidence). Analysis of original data from one study demonstrated a higher FEV1 % predicted (MD 7.05, 95% CI 3.15 to 10.95; P = 0.0004), FVC (MD 7.83, 95% CI 2.48 to 13.18; P = 0.004) and FEF25-75 (MD 7.05, 95% CI 3.15 to 10.95; P = 0.0004) in the CCPT group; however, the study reported no difference between groups (likely because the original analysis accounted for baseline differences). AUTHORS' CONCLUSIONS We are uncertain whether CCPT has a more positive impact on respiratory function, respiratory exacerbations, individual preference, adherence, quality of life, exercise capacity and other outcomes when compared to alternative ACTs as the certainty of the evidence is very low. There was no advantage in respiratory function of CCPT over alternative ACTs, but this may reflect insufficient evidence rather than real equivalence. Narrative reports indicated that participants prefer self-administered ACTs. This review is limited by a paucity of well-designed, adequately powered, long-term studies. This review cannot yet recommend any single ACT above others; physiotherapists and people with CF may wish to try different ACTs until they find an ACT that suits them best.

Abstract
BACKGROUND Cystic fibrosis (CF) is an inherited progressive life-limiting disease characterised by the build-up of abnormally thick, sticky mucus affecting mostly the lungs, pancreas, and digestive system. Airway clearance techniques (ACTs), traditionally referred to as chest physiotherapy, are recommended as part of a complex treatment programme for people with CF. The aim of an ACTs is to enhance mucociliary clearance and remove viscous secretions from the airways within the lung to prevent distal airway obstruction. This reduces the infective burden and associated inflammatory effects on the airway epithelia. There are a number of recognised ACTs, none of which have shown superiority in improving short-term outcomes related to mucus transport. This systematic review, which has been updated regularly since it was first published in 2000, considers the efficacy of ACTs compared to not performing any ACT in adults and children with CF. It is important to continue to review this evidence, particularly the long-term outcomes, given the recent introduction of highly effective modulator therapies and the improved health outcomes and potential changes to CF management associated with these drugs. OBJECTIVES To determine the effectiveness and acceptability of airway clearance techniques compared to no airway clearance techniques or cough alone in people with cystic fibrosis. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register, which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings, to 17 October 2022. We searched ongoing trials registers (Clinicaltrials.gov and the WHO International Clinical Trials Registry Platform) to 7 November 2022. SELECTION CRITERIA We included randomised or quasi-randomised studies that compared airway clearance techniques (chest physiotherapy) with no airway clearance techniques or spontaneous cough alone in people with CF. DATA COLLECTION AND ANALYSIS Both review authors independently assessed study eligibility, extracted data, and assessed the risk of bias of the included studies. We used GRADE methodology to assess the certainty of the evidence. MAIN RESULTS We included 11 cross-over studies (153 participants) and one parallel study (41 participants). There were differences between studies in how the interventions were delivered, with several intervention groups combining more than one ACT. One study used autogenic drainage; five used conventional chest physiotherapy; nine used positive expiratory pressure (PEP), with one study varying the water pressure between arms; three studies used oscillating PEP; two used exercise; and two used high-frequency chest wall oscillation (HFCWO). Of the 12 included studies, 10 were single-treatment studies, and two delivered the intervention over two consecutive days (once daily in one study, twice daily in the second). This substantial heterogeneity in the treatment interventions precluded pooling of data for meta-analysis. Blinding of participants, caregivers, and clinicians is impossible in airway clearance studies; we therefore judged all studies at unclear risk of performance bias. Lack of information in eight studies made assessment of risk of bias unclear for most other domains. We rated the certainty of evidence as low or very low due to the short-term cross-over trial design, small numbers of participants, and uncertain risk of bias across most or all domains. Six studies (84 participants) reported no effect on pulmonary function variables following intervention; but one study (14 participants) reported an improvement in pulmonary function following the intervention in some of the treatment groups. Two studies reported lung clearance index: one (41 participants) found a variable response to treatment with HFCWO, whilst another (15 participants) found no effect on lung clearance index with PEP therapy (low-certainty evidence). Five studies (55 participants) reported that ACTs, including coughing, increased radioactive tracer clearance compared to control, while a further study (eight participants) reported no improvement in radioactive tracer clearance when comparing PEP to control, although coughing was discouraged during the PEP intervention. We rated the certainty of evidence on the effect of ACTs on radioactive tracer clearance as very low. Four studies (46 participants) investigated the weight of mucus cleared from the lungs and reported greater secretions during chest physiotherapy compared to a control. One study (18 participants) reported no differences in sputum weight (very low-certainty evidence). AUTHORS' CONCLUSIONS The evidence from this review shows that ACTs may have short-term effects on increasing mucus transport in people with CF. All included studies had short-term follow-up; consequently, we were unable to draw any conclusions on the long-term effects of ACTs compared to no ACTs in people with CF. The evidence in this review represents the use of airway clearance techniques in a CF population before widespread use of cystic fibrosis transmembrane conductance regulator (CFTR) modulators. Further research is needed to determine the effectiveness and acceptability of airway clearance in those treated with highly effective CFTR modulators.

Abstract
AIM This study aimed to determine the effect of assisted autogenic drainage (AAD) with or without bouncing (BAAD) on both acid and non-acid gastroesophageal reflux (GER) in infants <1 year. METHODS During a 24-h multichannel intraluminal impedance-pH monitoring (MII-pH), infants were treated with a 20-min intervention of AAD (in supine position) or BAAD (in upright position), 2 h postprandial. In this controlled trial with intra-subject design, the number of reflux episodes (REs) was the primary outcome measure. The results during AAD and BAAD were compared to a baseline period before intervention and 20 min after intervention. RESULTS Overall, 50 infants were included in both groups. During AAD a significant decrease of RE's was found compared to baseline (p = 0.001). No significant differences were found in the BAAD group compared to baseline (p = 0.125). CONCLUSION AAD and BAAD do not cause or increase GER in infants under the age of 1 year.

Abstract
Background Despite unclear evidence of effectiveness or safety, airway clearance therapy (ACT) is frequently performed in infants and children with acute pulmonary disease. Objectives The aim of this review was to critically synthesise published evidence, expert opinion and pathophysiological principles to describe the indications, effects, precautions and application of commonly used ACT modalities for managing infants and children with acute pulmonary disease. Method A comprehensive narrative review of published literature was conducted. Articles describing paediatric populations were prioritised, but adult and animal studies were also considered where appropriate. Results There is a dearth of high-level evidence supporting the use of ACT in acutely ill infants and children. Conversely, studies have highlighted the lack of effect of different modalities for a variety of conditions, and in some cases serious associated complications have been reported.Airway clearance therapy may be considered when there is retention of pulmonary secretions, and the consequential airway obstruction impacts either acutely on respiratory mechanics and gaseous exchange and/or has the potential for long-term adverse sequelae [a condition that is the consequence of a previous disease or injury]. However, it should not be considered a routine intervention. Conclusion Airway clearance therapy should not be performed routinely in children admitted to hospital with acute respiratory conditions. Patients should be clinically assessed and treatment planned according to individual presentation, in those with signs and symptoms that are potentially amenable to ACT. Clinical implications This review can serve as a guide for physiotherapists in the respiratory management of children with acute respiratory illness, as well as identifying areas for clinical research.

Standard (head-down tilt) versus modified (without head-down tilt) postural drainage in infants and young children with cystic fibrosis. Cochrane Database Syst Rev 2018; 3:CD010297.

Abstract
BACKGROUND Postural drainage is used primarily in infants with cystic fibrosis from diagnosis up to the moment when they are mature enough to actively participate in self-administered treatments. However, there is a risk of gastroesophageal reflux associated with this technique.This is an update of a review published in 2015. OBJECTIVES To compare the effects of standard postural drainage (15º to 45º head-down tilt) with modified postural drainage (15º to 30º head-up tilt) with regard to gastroesophageal reflux in infants and young children up to six years old with cystic fibrosis in terms of safety and efficacy. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register. We also searched the reference lists of relevant articles and reviews. Additional searches were conducted on ClinicalTrials.gov and on the WHO International Clinical Trials Registry Platform for any planned, ongoing and unpublished studies.The date of the most recent literature searches: 19 June 2017. SELECTION CRITERIA We included randomised controlled studies that compared two postural drainage regimens (standard and modified postural drainage) with regard to gastroesophageal reflux in infants and young children (up to and including six years old) with cystic fibrosis. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. Two review authors independently identified studies for inclusion, extracted outcome data and assessed risk of bias. We resolved disagreements by consensus or by involving a third review author. We contacted study authors to obtain missing or additional information. The quality of the evidence was assessed using GRADE. MAIN RESULTS Two studies, involving a total of 40 participants, were eligible for inclusion in the review. We included no new studies in the 2018 update. The included studies were different in terms of the age of participants, the angle of tilt, the reported outcomes, the number of sessions and the study duration. The following outcomes were measured: appearance or exacerbation of gastroesophageal reflux episodes; percentage of peripheral oxygen saturation; number of exacerbations of upper respiratory tract symptoms; number of days on antibiotics for acute exacerbations; chest X-ray scores; and pulmonary function tests. One study reported that postural drainage with a 20° head-down position did not appear to exacerbate gastroesophageal reflux. However, the majority of the reflux episodes in this study reached the upper oesophagus (moderate-quality evidence). The second included study reported that modified postural drainage (30° head-up tilt) was associated with fewer number of gastroesophageal reflux episodes and fewer respiratory complications than standard postural drainage (30° head-down tilt) (moderate-quality evidence). The included studies had an overall low risk of bias. One included study was funded by the Sydney Children's Hospital Foundation and the other by the Royal Children's Hospital Research Foundation and Physiotherapy Research Foundation of Australia. Data were not able to be pooled by meta-analysis due to differences in the statistical presentation of the data. AUTHORS' CONCLUSIONS The limited evidence regarding the comparison between the two regimens of postural drainage is still weak due to the small number of included studies, the small number of participants assessed, the inability to perform any meta-analyses and some methodological issues with the studies. However, it may be inferred that the use of a postural regimen with a 30° head-up tilt is associated with a lower number of gastroesophageal reflux episodes and fewer respiratory complications in the long term. The 20° head-down postural drainage position was not found to be significantly different from the 20° head-up tilt modified position. Nevertheless, the fact that the majority of reflux episodes reached the upper oesophagus should make physiotherapists carefully consider their treatment strategy. We do not envisage that there will be any new trials undertaken that will affect the conclusions of this review; therefore, we do not plan to update this review.

Abstract
OBJECTIVES To determine the influence of modern airway clearance techniques using assisted autogenic drainage (AAD), whether or not combined with bouncing, on acid gastro-oesophageal reflux (GOR) in infants <1 year. METHODS In this controlled trial with intra-subject design infants were studied using oesophageal pH monitoring over 24 h, during which they received one 15 min session of bouncing, AAD or bouncing combined with AAD (BAAD). The number of reflux episodes (RE) and the refluxindex (RI) were the outcome measures. The results obtained during (T15) and 15 min after the intervention (T30) were compared to a period of 15 min before treatment (T0). RESULTS The results of 150 infants, evenly distributed over the three treatment groups, were analyzed. No significant differences were found in number of RE at T15 and T30 compared to T0 in the bouncing group (P = 0.42), the AAD group (P = 0.14), and the BAAD group (P = 0.91). RI was significantly lower in the AAD group at T15 compared to T0 (P < 0.01). No differences in RI were found in the bouncing group (P = 0.28), nor in the BAAD group (P = 0.81). CONCLUSION Bouncing, AAD and BAAD do not induce, nor aggravate acid GOR in infants under the age of 1 year.

Abstract
Common symptoms of chronic suppurative lung disease or bronchiectasis in children and adolescents are chronic cough with sputum production, retention of excess secretions in dilated airways, and a history of recurrent infections. Clinical management includes the prescription of airway-clearance techniques (ACTs) to facilitate mucociliary clearance, optimize sputum expectoration, relieve symptoms, and improve well-being. A wide range of ACTs are available for selection, and these strategies may be applied in isolation or in combination. The choice of technique will depend in part on the age of the child, their clinical state, and factors which may influence treatment adherence. While the evidence base for ACTs in children and adolescent with these conditions is not robust, the current available evidence in addition to clinical expertise provides guidance for technique prescription and clinical effect. An overview of the most commonly applied ACTs, including their physiological rationale and discussion of factors influencing prescription in children and adolescents is outlined in this review.

Abstract
OBJECTIVES To determine the influence of physiotherapy using intrapulmonary percussive ventilation on gastro-oesophageal reflux (GOR) in infants <1 year. METHODS In this controlled trial with intra-subject design, children were studied using multichannel intraluminal impedance pH (pH-MII) monitoring over 24 hr, during which they received one 20-min session of intrapulmonary percussive ventilation in upright position (IPVR ), 2 hr after their latest feeding. Two hours after each feeding, the number of reflux episodes (RE) over a 20-min period was registered for each infant and a mean per 20 min was calculated in order to obtain a baseline value. The number of RE during IPVR intervention was compared to baseline. RESULTS Fifty infants with a median age of 133 days were recruited of whom 21 were diagnosed with pathological GOR. During IPVR , the incidence of RE in the entire group was significantly lower compared to baseline; median (inter-quartile range [IQR]) 0 (0-1) versus 0.71 (0-1.33) RE, respectively, P = 0.003. The subgroup with abnormal GOR showed also a significant decrease of RE during IPVR ; median (IQR) 0 (0-1) versus 1.17 (0.55-2.16) RE, respectively, P = 0.03. No difference was detected in the group with normal reflux; median (IQR) 0.6 (0-1) compared to 0 (0-1) RE, respectively, P = 0.34. CONCLUSION IPVR does not induce, nor aggravate GOR in infants without and with pathological GOR, respectively, but on the contrary decreases the number of RE in patients with pathological reflux.

Abstract
For many years physiotherapy for cystic fibrosis (CF) was synonymous with a daily routine of postural drainage and percussion. Improved longevity and a desire for independence, together with a clearer understanding of the pathophysiology of the disease, has led to the development of many airway clearance techniques. The contribution of ‘chest’ physiotherapy remained unchallenged until recent times when lack of robust evidence and the presentation of asymptomic infants and adults led some physiotherapists to question this traditional approach. As survival increases into the fourth and fifth decade unique complications have evolved and physiotherapy management is challenged with nonrespiratory aspects of treatment. This review will consider the evidence for, and current practice of airway clearance, the value of exercise and the emerging problems of musculoskeletal complications and incontinence.

Abstract
Chronic cough and sputum production are common featuresof chronic obstructive pulmonary disease (COPD) and havea significant impact on exacerbation frequency and qualityof life. Despite this, techniques to assist with removal of sputum from the airway do not have a well-defined role in COPD management. Clinical trials of airway clearance techniques (ACTs) in COPD have shown mixed results with little evidence of long-term benefit. However many studies havefailed to account for the heterogeneity of COPD lung disease, particularly with regard to the presence of bronchiectasis. Analysis of short-term studies suggests that there may be a cohort of patients who will benefit from prescription of a sputum clearance regimen. This review proposes a physiological rationale for the use of ACTs in COPD, taking into consideration the presence of bronchiectasis, the amount of sputum produced, the degree of airflow obstruction and the presence of decreased lung elastic recoil. The selection of an optimal ACT for individuals with COPD should take into account its effects on lung vloumes, expiratory flow and dynamic airway compression. Care should be taken to avoid airway collapse during forced expirations in patients with reduced lung recoil pressure; positive expiratory pressure therapy or autogenic drainage may prove effective in this patient group. The acceptability of ACTs to patients should also be considered, especially where long-term adherence is required. Future research should focus on more appropriate matching of the physiological effects of individual ACTs to the pathophysiology of lung disease in COPD.

Abstract
Physiotherapy management is a key element of care for people with cystic fibrosis (CF) throughout the lifespan. Although considerable evidence exists to support physiotherapy management of CF, there is documented variation in practice. The aim of this guideline is to optimize the physiotherapy management of people with CF in Australia and New Zealand. A systematic review of the literature in key areas of physiotherapy practice for CF was undertaken. Recommendations were formulated based on National Health and Medical Research Council (Australia) guidelines and considered the quality, quantity and level of the evidence; the consistency of the body of evidence; the likely clinical impact; and applicability to physiotherapy practice in Australia and New Zealand. A total of 30 recommendations were made for airway clearance therapy, inhalation therapy, exercise assessment and training, musculoskeletal management, management of urinary incontinence, managing the newly diagnosed patient with CF, delivery of non-invasive ventilation, and physiotherapy management before and after lung transplantation. These recommendations can be used to underpin the provision of evidence-based physiotherapy care to people with CF in Australia and New Zealand.

Abstract
BACKGROUND The aim of this systematic literature review was to grade the levels of evidence of the most widely used manual airway clearance techniques. METHODS A literature search was conducted over the period 1995-2014 from the Medline, PEDro, ScienceDirect, Cochrane Library, REEDOC and kinedoc databases, with the following keywords: "postural drainage", "manual vibrations", "manual chest percussion", "directed cough", "increased expiratory flow", "ELTGOL", "autogenic drainage" and "active cycle of breathing technique". RESULTS Two-hundred and fifty-six articles were identified. After removing duplicates and reading the titles and abstracts, 63 articles were selected, including 9 systematic reviews. This work highlights the lack of useful scientific data and the difficulty of determining levels of evidence for manual airway clearance techniques. Techniques were assessed principally with patients with sputum production (cystic fibrosis, DDB, COPD, etc.). It also shows the limited pertinence of outcome measures to quantify congestion and hence the efficacy of airway clearance techniques. CONCLUSION The 1994 consensus conference summary table classifying airway clearance techniques according to physical mechanism provides an interesting tool for assessment, grouping together techniques having identical mechanisms of action. From the findings of the present systematic review, it appears that only ELTGOL, autogenic drainage and ACBT present levels of evidence "B". All other techniques have lower levels of evidence. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND Chest physiotherapy is widely used in people with cystic fibrosis in order to clear mucus from the airways. This is an updated version of previously published reviews. OBJECTIVES To determine the effectiveness and acceptability of chest physiotherapy compared to no treatment or spontaneous cough alone to improve mucus clearance in cystic fibrosis. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search of the Group's Cystic Fibrosis Trials Register: 02 June 2015. SELECTION CRITERIA Randomised or quasi-randomised clinical studies in which a form of chest physiotherapy (airway clearance technique) were taken for consideration in people with cystic fibrosis compared with either no physiotherapy treatment or spontaneous cough alone. DATA COLLECTION AND ANALYSIS Both authors independently assessed study eligibility, extracted data and assessed the risk of bias in the included studies. There was heterogeneity in the published outcomes, with variable reporting which meant pooling of the data for meta-analysis was not possible. MAIN RESULTS The searches identified 157 studies, of which eight cross-over studies (data from 96 participants) met the inclusion criteria. There were differences between studies in the way that interventions were delivered, with several of the intervention groups combining more than one treatment modality. One included study looked at autogenic drainage, six considered conventional chest physiotherapy, three considered oscillating positive expiratory pressure, seven considered positive expiratory pressure and one considered high pressure positive expiratory pressure. Of the eight studies, six were single-treatment studies and in two, the treatment intervention was performed over two consecutive days (once daily in one, twice daily in the other). This enormous heterogeneity in the treatment interventions prevented any meta-analyses from being performed. Blinding of participants, caregivers or clinicians in airway clearance studies is impossible; therefore this was not considered as a high risk of bias in the included studies. Lack of protocol data made assessment of risk of bias unclear for the majority of other criteria.Four studies, involving 28 participants, reported a higher amount of expectorated secretions during chest physiotherapy as compared to a control. One study, involving 18 participants, reported no significant differences in sputum weight. In five studies radioactive tracer clearance was used as an outcome variable. In three of these (28 participants) it was reported that chest physiotherapy, including coughing, increased radioactive tracer clearance as compared to the control period. One study (12 participants) reported increased radioactive tracer clearance associated with all interventions compared to control, although this was only reported to have reached significance for postural drainage with percussion and vibrations; and the remaining study (eight participants) reported no significant difference in radioactive tracer clearance between chest physiotherapy, without coughing, compared to the control period. Three studies, involving 42 participants reported no significant effect on pulmonary function variables following intervention; but one further study did report significant improvement in pulmonary function following the intervention in some of the treatment groups. AUTHORS' CONCLUSIONS The results of this review show that airway clearance techniques have short-term effects in the terms of increasing mucus transport. No evidence was found on which to draw conclusions concerning the long-term effects.

Abstract
PURPOSE To provide a survey on the literature concerning the influence of respiratory physiotherapy on gastro-oesophageal reflux (GOR) in infants and young children. METHODS Electronic databases (Pubmed, Web of Science, PEDro) and reference lists of articles and narrative reviews were searched. Articles were included when infants and small children underwent oesophageal pH monitoring or pH-multichannel intraluminal impedance monitoring while respiratory physiotherapy was administered. Descriptive analysis was performed and two researchers scored the methodological quality of these studies. RESULTS Out of 985 articles, seven (six English, one French) have been included, In total 277 patients were involved, 71 with cystic fibrosis. Depending on the technique used, four studies showed GOR to be aggravated during therapy, three studies reported no effect. CONCLUSION The evidence is not conclusive on whether respiratory physiotherapy induces or aggravates GOR in infants and small children. Age, disease, and treatment options play an important role. More specific research, also focussing on the influence of respiratory physiotherapy on non-acid reflux and the impact of recently developed airway clearance techniques (ACT's) on GOR is necessary.

Abstract
Despite widespread practice, there is very little, high-level evidence supporting the indications for and effectiveness of cardiopulmonary/chest physiotherapy (CPT) in critically ill infants and children. Conversely, most studies highlight the detrimental effects or lack of effect of different manual modalities. Conventional CPT should not be a routine intervention in the pediatric intensive care unit, but can be considered when obstructive secretions are present which impact on lung mechanics and/or gaseous exchange and/or where there is the potential for long-term complications. Techniques such as positioning, early mobilization, and rehabilitation have been shown to be beneficial in adult intensive care patients; however, little attention has been paid to this important area of practice in pediatric intensive care units. This article presents a narrative review of chest physiotherapy in pediatric critical illness, including effects, indications, precautions, and specific treatment modalities and techniques.

Abstract
Gastroesophageal reflux (GER) is common in patients with cystic fibrosis (CF) and is often regarded as playing a role in the pathogenesis of CF lung disease. Individuals with CF have many predisposing factors to the development of GER, with a reported prevalence ranging from 35 to 81%. Several studies have suggested that patients with CF who have coexisting GER have more severe lung disease with lower pulmonary function and increased numbers of respiratory exacerbations. Furthermore, GER may alter the respiratory microbiology in CF. Both the acid and nonacid components of GER may have an effect on lung disease. More than 50% of U.S. patients with CF were being treated with proton pump inhibitors in 2012; however, data regarding safety and efficacy of these agents in CF are lacking. Pharmacologic and surgical treatment of GER may improve respiratory morbidity, although prospective controlled studies have not been performed. Given the lack of evidence-based guidelines for evaluation, diagnosis, and treatment of GER in CF, initiation of treatment for symptomatic GER should be based on standard guidelines for the general population. Because there is no clear evidence that GER leads to worse respiratory outcomes in CF or that treatment of GER improves pulmonary outcomes, invasive testing for GER in patients without reflux symptoms is not warranted. Further studies to determine the role of GER in CF lung disease and the risks and benefits of surgical and pharmacologic therapy for GER are warranted.

Abstract
BACKGROUND Postural drainage is used primarily in infants with cystic fibrosis from diagnosis up to the moment when they are mature enough to actively participate in self-administered treatments. However, there is a risk of gastroesophageal reflux associated with this technique. OBJECTIVES To compare the effects of standard postural drainage (greater (30° to 45° head-down tilt) and lesser (15° to 20° head-down tilt)) with modified postural drainage (greater (30º head-up tilt) or lesser (15º to 20º head-up tilt)) with regard to gastroesophageal reflux in infants and young children up to six years old with cystic fibrosis in terms of safety and efficacy. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register. We also searched the reference lists of relevant articles and reviews. Additional searches were conducted on ClinicalTrials.gov and on the WHO International Clinical Trials Registry Platform for any planned, ongoing and unpublished studies.The date of the most recent literature searches: 20 January 2015. SELECTION CRITERIA We included randomised controlled studies that compared two postural drainage regimens (standard and modified postural drainage) with regard to gastroesophageal reflux in infants and young children (up to and including six years old) with cystic fibrosis. DATA COLLECTION AND ANALYSIS Two review authors independently selected the studies to be included in the review, assessed their risk of bias and extracted data. MAIN RESULTS Two studies, including 40 participants, were eligible for inclusion in the review. The studies were different in terms of the age of participants, the angle of tilt, the reported outcomes, the number of sessions and the study duration. The following outcomes were measured: appearance or exacerbation of gastroesophageal reflux episodes; percentage of peripheral oxygen saturation; number of exacerbations of upper respiratory tract symptoms; number of days on antibiotics for acute exacerbations; chest X-ray scores; and pulmonary function tests. One study reported that postural drainage with a 20° head-down position did not appear to exacerbate gastroesophageal reflux. However, the majority of the reflux episodes reached the upper oesophagus. The second included study reported that modified postural drainage (30º head-up tilt) was associated with fewer number of gastroesophageal reflux episodes and fewer respiratory complications than standard postural drainage (30º head-down tilt). The included studies had an overall low risk of bias. Data were not able to be pooled by meta-analysis due to differences in the statistical presentation of the data. AUTHORS' CONCLUSIONS The available evidence regarding the comparison between the two regimens of postural drainage is still weak due to the small number of included studies, the small number of participants assessed, the inability to perform any meta-analyses and some methodological issues with the studies. However, it may be inferred that the use of a postural regimen with a 30° head-up tilt is associated with a lower number of gastroesophageal reflux episodes and fewer respiratory complications in the long term. The 20º head-down postural drainage position was not found to be significantly different from the 20º head-up tilt modified position. Nevertheless, the fact that the majority of reflux episodes reached the upper oesophagus should make physiotherapists carefully consider their treatment strategy.

Abstract
Background Gastro esophageal reflux (GER) is common in cystic fibrosis (CF) and may contribute to lung disease. Approximately 50% of patients with cystic fibrosis are being treated with proton pump inhibitors (PPIs). Methods In a randomized controlled study in adults, we compared treatment with esomeprazole 40 mg twice daily versus placebo in patients with CF and frequent respiratory exacerbations over a thirty-six week treatment period to determine effect on time to first exacerbation and other health related outcomes. Results 17 patients without symptoms of GER were randomized and 15 completed the study. 13 subjects underwent 24 hour ambulatory pH probe monitoring; 62% had pH probe evidence of GER. Forty one percent of subjects had a pulmonary exacerbation during the study. There was no significant difference in time to first pulmonary exacerbation (log rank test p = 0.3169). Five of nine subjects in the esomeprazole group compared with 2 of eight subjects in the placebo group experienced exacerbations (esomeprazole vs. placebo: odds ratio = 3.455, 95% CI = (0.337, 54.294), Fisher’s exact test: p = 0.334). There was no change in Forced Expiratory Volume in one second, Gastroesophageal Symptom Assessment Score or CF Quality of Life score between the two treatment groups. Conclusions There was a trend to earlier exacerbation and more frequent exacerbations in subjects randomized to esomeprazole compared with placebo. The effect of proton pump inhibitors on pulmonary exacerbations in CF warrants further investigation. Clinical trials registration Clinicaltrials.gov, NCT01983774

Abstract
Optimisation of physiotherapy techniques to improve outcomes is an area of cystic fibrosis (CF) care, which has developed considerably over the last two decades. With the introduction of newborn screening and an increase in median life expectancy, the management of individuals with CF has needed to adapt to a more dynamic and individualised approach. It is essential that CF physiotherapy management reflects the needs of a changing cohort of paediatric CF patients and it is no longer justifiable to adopt a 'blanket' prescriptive approach to care. The areas of physiotherapy management which are reviewed and discussed in this paper include inhalation therapy, airway clearance techniques, the management of newborn screened infants, physical activity and exercise.

Abstract
In cystic fibrosis (CF), a defect in ion transport results in thick and dehydrated airway mucus, which is difficult to clear, making such patients prone to chronic inflammation and bacterial infections. Physiotherapy using a variety of airway clearance techniques (ACTs) represents a key treatment regime by helping clear the airways of thickened, adhered, mucus and, thus, reducing the impact of lung infections and improving lung function. This article aims to bridge the gap between our understanding of the physiological effects of mechanical stresses elicited by ACTs on airway epithelia and the reported effectiveness of ACTs in CF patients. In the first part of this review, the effects of mechanical stress on airway epithelia are discussed in relation to changes in ion transport and stimulation in airway surface layer hydration. The second half is devoted to detailing the most commonly used ACTs to stimulate the removal of mucus from the airways of patients with CF.

Abstract
Lung disease in patients with cystic fibrosis is characterised by inflammation and recurrent and chronic infections leading to progressive loss in pulmonary function and respiratory failure. Early management of disease results in substantially improved pulmonary function at first testing (at roughly 6 years of age), but the annual decline in pulmonary function tests in older patients has remained unchanged showing how important the early years are in the disease process. Treatment regimens for patients with cystic fibrosis have changed from predominantly symptomatic treatment to preventive or causal (ie, treatments that address the underlying mechanisms of disease) therapeutic interventions. The infant and preschool age (2-5 years) could represent a unique period of opportunity to postpone or even prevent the onset of cystic fibrosis lung disease. We summarise the current knowledge and the methods used to characterise and quantify early lung disease. We discuss treatment strategies including new drugs that are being developed and their potential role in the treatment of early lung disease in patients with cystic fibrosis.

Abstract
Progression of lung disease is a major event in children with cystic fibrosis (CF), but regional differences in its evolution are unclear. We hypothesized that regional differences occur beginning in early childhood. We examined this issue by evaluating 132 patients followed in the Wisconsin Neonatal Screening Project between 1985 and 2010. We scored chest X-rays obtained every 1-2 years with the Wisconsin chest X-ray system, in which we divided the lungs into quadrants, and gave special attention to ratings for bronchiectasis (BX) and nodular/branching opacities. We compared the upper and lower quadrant scores, and upper right and left quadrant scores, as patients aged using a multivariable generalized estimation equation (GEE) model. We did a confirmatory analysis for a subset of 81 patients with chest computerized tomography (CT) images obtained in 2000 and scored using the Brody scoring system. The chest X-ray analysis shows that the upper quadrants have higher BX (P<0.001) and nodular/branching opacities (P<0.001) scores than the lower quadrants. CT analysis likewise reveals that the upper quadrants have more BX (P=0.02). Patients positive for mucoid PA showed significantly higher BX scores than patients with non-mucoid PA (P=0.001). Chest X-ray scoring also revealed that the upper right quadrant has more BX (P<0.001) than the upper left quadrant, and CT analysis was again confirmatory (P<0.001). We conclude that pediatric patients with CF develop more severe lung disease in the upper lobes than the lower lobes in association with mucoid PA infections and also have more severe lung disease on the right side than on the left side in the upper quadrants. A variety of potential explanations such as aspiration episodes may be clinically relevant and provide insights regarding therapies.

Abstract
BACKGROUND Gastro-esophageal reflux (GOR) may contribute to lung disease in children with cystic fibrosis (CF). There is conflicting evidence regarding the effect of chest physiotherapy (CPT) in the head-down position on GOR. Furthermore, there is currently no evidence on the impact of physiotherapy on GOR as assessed by pH-multichannel intraluminal impedance (pH-MII). AIMS (1) To characterize GOR in young children with CF. (2) To determine whether the head-down position during physiotherapy exacerbates GOR. METHODS Children were studied using pH-MII monitoring over 24-hr, during which they received two 20-min sessions of CPT. One session was performed in "modified" drainage positions with no head-down tilt and the alternate session in "gravity-assisted" drainage positions, which included 20° head-down tilt. RESULTS Twenty children with CF (8 males), median age 12 months (range 8-34) were recruited. A total of 1,374 reflux episodes were detected in all children, of which 869 (63%) were acid and 505 (37%) were non-acid. Seventy-two percent of the episodes migrated proximally. During CPT, there was no significant difference between total number of reflux episodes in the modified or gravity-assisted positions, median [inter-quartile range (IQR)] 1 (0-2.5) compared to 1 (0.75-3) episode, respectively, P = 0.63. There was also no significant difference between the number of reflux episodes which migrated proximally, median (IQR) 1 (0-2) compared to 0 (0-2) episodes, respectively, P = 0.75. CONCLUSION In young children with CF, GOR is primarily acidic and proximal migration is common. Physiotherapy in the head-down position does not appear to exacerbate GOR. The impact of GOR on lung disease remains to be elucidated.

Abstract
Newborn screening for cystic fibrosis (CF) offers the opportunity for early medical and nutritional intervention that can lead to improved outcomes. Management of the asymptomatic infant diagnosed with CF through newborn screening, prenatal diagnosis, or sibling screening is different from treatment of the symptomatically diagnosed individual. The focus of management is on maintaining health by preventing nutritional and respiratory complications. The CF Foundation convened a committee to develop recommendations based on a systematic review of the evidence and expert opinion. These guidelines encompass monitoring and treatment recommendations for infants diagnosed with CF and are intended to help guide families, primary care providers, and specialty care centers in the care of infants with CF.

Abstract
OBJECTIVE To inform the development of Cystic Fibrosis (CF) Foundation guidelines on the care of infants with CF, we systematically reviewed the evidence for diagnosis and assessment of pancreatic and pulmonary disorders; management of pancreatic and pulmonary function; management of nutrition and nutritional disorders; and prevention and control of infections. STUDY DESIGN In May-June 2008, we searched The Cochrane Library for existing reviews; and MEDLINE, the National Guideline Clearinghouse, the CF Foundation Clinical Practice Guidelines and Consensus Statements, and the UK CF Trust for existing guidelines. MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and the Excerpta Medica Database (EMBASE) were searched for primary studies in January 2008. Bibliographies of eligible articles were searched and expert input was sought. We selected English-language articles of any study design that provided original data on any of our questions on infants up to 2 years of age. RESULTS We identified 14 relevant guidelines and 3 Cochrane reviews. Fifty-nine articles (55 primary studies) were included. Only four of these were randomized controlled trials. Sample sizes of infants ranged from 2 to 768 study participants; the median sample size was 24. Of our 21 review topics, 5 topics had only one study while for 5 we identified no relevant studies. We identified one or no primary studies for 20 of 32 review questions. CONCLUSIONS There is a paucity of evidence on the care of infants diagnosed with CF. For several of the review questions no guidelines or primary studies were identified, but for other questions, studies limited by weak design and small sample sizes were the only studies identified. With increasing numbers of infants with CF being diagnosed by newborn screening there is an opportunity to study the management of infants diagnosed with CF.

Abstract
Cystic fibrosis is the most common lethal genetic disease in white populations. The outlook for patients with the disease has improved steadily over many years, largely as a result of earlier diagnosis, more aggressive therapy, and provision of care in specialised centres. Researchers now have a more complete understanding of the molecular-biological defect that underlies cystic fibrosis, which is leading to new approaches to treatment. One of these treatments, hypertonic saline, is already in use, whereas others are in advanced stages of development. We review clinical care for cystic fibrosis and discuss recent advances in the understanding of its pathogenesis, implementation of screening of neonates, and development of therapies aimed at treating the basic defect.

Abstract
The major morbidity and mortality associated with cerebral palsy (CP) relates to respiratory compromise. This manifests through repeated pulmonary aspiration, airway colonization with pathogenic bacteria, the evolution of bronchiectasis and sleep disordered breathing. An accurate assessment involving a multidisciplinary approach and relatively simple interventions for these conditions can lead to significant improvements in the quality of life of children with CP as well as their parents and carers. This review highlights the more common problems and potential therapies with regard to suppurative lung disease and sleep disordered breathing in children with CP.

Abstract
Despite the wide implementation of newborn screening for cystic fibrosis there have been few clinical trials aimed at reducing the burden of lung disease in screened infants. Emerging tools such as infant lung function and low-dose computed tomography (CT) provide early indicators of lung disease and could be effective outcome measures in randomized controlled trials (RCTs) of interventions that aim to delay or prevent the onset of bronchiectasis. The most recent data suggest that strategies to reduce neutrophilic inflammation and prevent infection are good candidates for RCTs. However, cooperation between centres is needed if they are to be large enough to detect differences due to the intervention that otherwise may be masked by subtle differences in management practices between centres, and to detect rare but significant adverse effects.

Abstract
BACKGROUND Babies with cystic fibrosis diagnosed by neonatal screening often display no overt signs of respiratory disease. The role of traditional routine daily chest physiotherapy in this particular group of babies is unclear and has generated considerable international debate. There is currently no evidence addressing this issue and present circumstances preclude a rigorous trial in the UK. This study aimed to provide expert consensus regarding the physiotherapy management of asymptomatic infants with CF. METHOD A Delphi consensus method was used to gather and refine expert opinions of senior paediatric physiotherapists in the UK. Agreement was sought on 16 statements reflecting aspects of physiotherapy management in 'asymptomatic' babies with cystic fibrosis. RESULTS Twenty-five senior paediatric physiotherapists from Specialist CF Centres throughout the UK participated in the study. Consensus was high amongst the respondents for 15 of the 16 statements. One statement failed to reach consensus. This related to the question of not routinely initiating a daily chest physiotherapy regimen in apparently healthy babies. Due to the lack of consensus an amendment to this statement was made, to allow a more flexible approach, where physiotherapists would not be obliged to initiate routine daily treatment in asymptomatic babies with CF, if they felt other another approach was justified. CONCLUSION There was high consensus of opinion amongst senior physiotherapists in the UK on most aspects of the physiotherapy management of babies with CF. Consensus could not be achieved on whether routine daily chest physiotherapy is necessary in 'asymptomatic' babies. An agreed amendment to the original statement allows professionals to modify or change traditional practice with the sanction of their senior colleagues. The results of this process will be used by the Association of Chartered Physiotherapists in Cystic Fibrosis to form the basis of national clinical guidelines.

Abstract
Chest physiotherapy in the form of airway clearance techniques and exercise has played an important role in the treatment of cystic fibrosis. Until the 1990s the primary airway clearance technique used was postural drainage combined with percussion and vibration (PD&P). It was introduced into the treatment of CF with little evidence to support its efficacy and once established, it has been difficult ethically to perform a study comparing PD&P to no treatment. A common question, yet unanswered is when should it be commenced, especially for the newly diagnosed asymptomatic CF patient? Recently, the technique of PD&P has been modified to include only non-dependant head-down positioning due to the detrimental effects of placing a person in a Trendelenburg position. In the 1990s other airway clearance techniques gained popularity, in that they could be performed independently, in a sitting position and avoided many of the detrimental effects of PD&P. These techniques include the Active cycle of breathing technique, formally called the Forced expiration technique and Autogenic drainage. Both these breathing techniques aim at using expiratory airflow to mobilize secretions up the airways and incorporate breathing strategies to assist in the homogeneity of ventilation. Studies suggest that both these techniques are as effective if not more effective than as PD&P and offer many advantages over PD&P. It has been suggested that exercise can be used as an airway clearance technique; however the literature does not support this. Rather, when exercise is used in addition to an airway clearance technique there is enhanced secretion removal and an overall benefit to the patient. Further research needs to be directed at assessing the effects of an airway clearance technique on the individual patient using appropriate outcome measures.

Abstract
BACKGROUND Cystic fibrosis is an inherited life-limiting disorder, characterised by pulmonary infections and thick airway secretions. Chest physiotherapy has been integral to clinical management in facilitating removal of airway secretions. Conventional chest physiotherapy techniques (CCPT) have depended upon assistance during treatments, while more contemporary airway clearance techniques are self-administered, facilitating independence and flexibility. OBJECTIVES To compare CCPT with other airway clearance techniques in terms of their effects on respiratory function, individual preference, adherence, quality of life and other outcomes. SEARCH STRATEGY We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group trials register which comprises references identified from comprehensive electronic database searches and handsearching of relevant journals and abstract books of conference proceedings. We also searched CINAHL from 1982 to 2002 and AMED from 1985 to 2002. Date of most recent search: January 2004. SELECTION CRITERIA Randomised or quasi-randomised clinical trials including those with a cross-over design where CCPT was compared with other airway clearance techniques. Studies of less than seven days duration were excluded. DATA COLLECTION AND ANALYSIS Two reviewers allocated quality scores to relevant studies and independently extracted data. If we were unable to extract data, we invited authors to submit their data. We excluded studies from meta-analysis when data were lost or study design precluded comparison. For some continuous outcomes, we used the generic inverse variance method for meta-analysis of data from cross-over trials and data from parallel-designed trials were incorporated for comparison. We also examined efficacy of specific techniques and effects of treatment duration. MAIN RESULTS Seventy-eight publications were identified by the searches. Twenty-nine of these were included, representing 15 data sets with 475 participants. There was no difference between CCPT and other airway clearance techniques in terms of respiratory function measured by standard lung function tests. Studies undertaken during acute exacerbations demonstrated relatively large gains in respiratory function irrespective of airway clearance technique. Longer-term studies demonstrated smaller improvements or deterioration over time. Ten studies reported individual preferences for technique, with participants tending to favour self-administered techniques. Heterogeneity in the measurement of preference precluded these data from meta-analysis. AUTHORS' CONCLUSIONS This review demonstrated no advantage of CCPT over other airway clearance techniques in terms of respiratory function. There was a trend for participants to prefer self-administered airway clearance techniques. Limitations of this review included a paucity of well-designed, adequately-powered, long-term trials.

Abstract
BACKGROUND Postural drainage chest physiotherapy in infants with cystic fibrosis (CF) exacerbates gastro-oesophageal reflux (GOR) and may contribute to a more rapid deterioration in lung function. AIMS To compare standard postural drainage chest physiotherapy (SPT) and a modified physiotherapy regimen (MPT) without head-down tilt, with regard to GOR, arousal state, and cardiorespiratory function. METHODS Twenty infants with CF underwent 30 hour oesophageal pH monitoring, during which four chest physiotherapy sessions were administered (day 1: MPT-SPT; day 2: SPT-MPT). Arousal state, heart rate, and oxygen saturation were documented for each of the physiotherapy positions (supine, prone, right lateral, and left lateral with (SPT) or without (MPT) 30 degrees head-down tilt). RESULTS Significantly more reflux episodes occurred during SPT than during MPT, but there were no significant differences in median episode duration or fractional reflux time. During SPT, left lateral positioning was associated with fewer reflux episodes compared to other positions. During supine and prone positioning, more reflux episodes occurred during SPT than during MPT. Infants were significantly more likely to be awake or cry during SPT. There was a significant association between crying and reflux episodes for SPT. Non-nutritive sucking was associated with a significant reduction in reflux episodes during SPT. Oxygen saturation during SPT was significantly lower during crying and other waking, and non-nutritive sucking during SPT was associated with a significant increase in oxygen saturation. CONCLUSIONS SPT is associated with GOR, distressed behaviour, and lower oxygen saturation.

Abstract
BACKGROUND Chest physiotherapy is widely used in patients with cystic fibrosis in order to clear mucus from the airways. OBJECTIVES To determine the effectiveness and acceptability of chest physiotherapy compared to no treatment or spontaneous cough alone to improve mucus clearance in cystic fibrosis. SEARCH STRATEGY Relevant trials are identified in the Cochrane Cystic Fibrosis and Genetic Disorders Group Specialised Register of Controlled Trials. This register was compiled by conducting computerised searches of Medline from 1966 to present and from Embase from 1974 to 1995. The register of randomised controlled trials is updated every three months. Unpublished work has been identified by searching through the abstract books of the three major cystic fibrosis conferences; the International Cystic Fibrosis Conference: the European Cystic Fibrosis Conference and the North American Cystic Fibrosis Conference. Date of the most recent search of the Group's specialised register: November 1999. SELECTION CRITERIA Randomised or quasi-randomised clinical trials in which a form of chest physiotherapy (airway clearance technique) were taken for consideration in patients with cystic fibrosis compared with either no physiotherapy treatment or spontaneous cough alone. DATA COLLECTION AND ANALYSIS There were no randomised controlled trials or cross over trials eligible for inclusion in the review. MAIN RESULTS There were no randomised controlled trials or cross over trials eligible for inclusion in the review. REVIEWER'S CONCLUSIONS Short-term crossover trials, which had to be excluded from this review, suggest that airway clearance regimens could have beneficial effects in patients with cystic fibrosis. However based on this review there is currently no robust scientific evidence to support the hypothesis that chest physiotherapy for the purpose of clearing airway secretions has a beneficial effect in patients with cystic fibrosis.
