Chest Physiotherapy and Cystic Fibrosis: Conclusion

With a level of significance of 0.05 (type 1 error), a typical power of 0.85 (type 2 error), an inherent variability of 15 percent and a difference of 10 percent between treatments to be regarded as clinically significant—using paried t tests—the sample size required would be 23 subjects. Increasing the power to 0.95 in this…

Chest Physiotherapy and Cystic Fibrosis: Within-Subject Variability and Statistical Power

Subjects with CF vary not only from each other in terms of disease manifestations, but also they vary from day to day in their ability to reproduce pulmonary function tests. In CF subjects, the inherent variability in performing PFTs has been estimated to be as high as 15%; however, the individual’s variability has been shown…

Chest Physiotherapy and Cystic Fibrosis: Measurement Parameters

Physical therapy is only one part of CF management. Thus, it should not be viewed in isolation from the effects of nutrition, medication such as antibiotics, and overall care. Many studies seeking to quantify the effect of CPT on CF, measure the results in terms of changes in pulmonary function, arterial blood gas values, oxygen…

Chest Physiotherapy and Cystic Fibrosis: Exercise

Exercise tolerance is limited in CF patients by a number of factors including obstruction of the peripheral airways leading to increased residual volume and increased physiologic dead space, hypoxemia, intolerable dyspnea, and uncontrollable coughing. However, certain factors that limit resting expiratory flow rates in children with CF are alleviated during exercise. At rest, airway instability…

Chest Physiotherapy and Cystic Fibrosis: Compliance With Chest Physical Therapy

Compliance with daily CPT has been shown to slow pulmonary deterioration in patients with CF. A variety of studies indicate that while daily treatment might be advised, most patients do not comply. In general, CPT has the lowest compliance rate of any aspect of CF management, patient rate of compliance ranging from 26 to 47%….

Chest Physiotherapy and Cystic Fibrosis: Treatment

The appropriateness of CPT treatment and the selection of specific techniques provide yet another confounding variable. Studies resulting in poor performance for CPT often include conditions which would not clinically be treated. For example, the association between CPT and decreases in oxygenation has been noted by several authors. Connors et al (1980) studied the effects…

Chest Physiotherapy and Cystic Fibrosis: Definition of Techniques

The rationale for this support includes the inability of severely compromised patients to undertake exercise at the levels required, problems with compliance, acute exacerbation necessitating altered physical activity, and the concern that as the disease progresses, exercise may add another stress to an already stressed system. Given the beneficial effects of exercise on physiologic and…
