Physical therapist management of a patient with acute low back pain and elevated fear-avoidance beliefs.
Elevated fear-avoidance beliefs are believed to be a precursor of chronic disability, yet effective intervention options have not been described in the literature. The purpose of this case report is to describe physical therapist management of a patient with acute low back pain and elevated fear-avoidance beliefs. ⋯ Disability and fear-avoidance beliefs improved following a fear-avoidance-based physical therapy intervention. Research is warranted to investigate the effectiveness of this approach.

Individuals with cystic fibrosis (CF) have large amounts of infected mucus in their lungs, which causes irreversible lung tissue damage. Although patient-administered positive expiratory pressure (PEP) breathing has been promoted as an effective therapeutic modality for removing mucus and improving ventilation distribution in these patients, the effects of PEP on ventilation distribution and gas mixing have not been documented. Therefore, this preliminary investigation described responses in distribution of ventilation and gas mixing to PEP breathing for patients with moderate to severe CF lung disease. ⋯ This study demonstrated the physiologic basis for the efficacy of PEP therapy. The results confirm that low PEP and high PEP improve gas mixing in individuals with CF, and these improvements were associated with increased lung function, sputum expectoration, and SpO(2). The authors propose that improvements in gas mixing may lead to increases in oxygenation and thus functional exercise capacity.
