Cognitive functional therapy compared with core exercise and manual therapy in patients with chronic low back pain: randomised controlled trial.

Cognitive functional therapy (CFT) is a physiotherapy-led intervention that has evolved from an integration of foundational behavioral psychology and neuroscience within the physiotherapist practice directed at the multidimensional nature of chronic low back pain (CLBP). The current evidence about the comparative effectiveness of CFT for CLBP is still scarce. We aimed to investigate whether CFT is more effective than core training exercise and manual therapy (CORE-MT) in pain and disability in patients with CLBP.

Proposal intensity adequacy of expiratory effort and heart rate behavior during the valsalva maneuver in preadolescents.

Background: When performing the Valsalva maneuver (VM), adults and preadolescents produce the same expiratory resistance values.

Objective: To analyze heart rate (HR) in preadolescents performing VM, and propose a new method for selecting expiratory resistance.

Method: The maximal expiratory pressure (MEP) was measured in 45 sedentary children aged 9-12 years who subsequently performed VM for 20 s using an expiratory pressure of 60%, 70%, or 80% of MEP.
