Randomized Controlled Trial
Examining what factors mediate treatment effect in chronic low back pain: a mediation analysis of a Cognitive Functional Therapy clinical trial.
Cognitive Functional Therapy (CFT) is a physiotherapist-led individualized intervention for people with people with non-specific chronic low back pain (CLBP), involving biopsychosocial pain education, graded movement exposure and lifestyle coaching. ⋯ An exploration of seven potential mediators was undertaken to determine the effect of Cognitive Functional Therapy (CFT) on disability and pain intensity in individuals with chronic low back pain compared to a group exercise and education intervention. CFT improved pain self-efficacy, which was associated with disability and pain outcomes. CFT did not improve the other six potential mediators (stress, fear of physical activity, coping, depression, anxiety and sleep) and these were not associated with disability or pain. The proportion of missing data in this study is substantial and these findings should be considered hypothesis-generating only.

Randomized Controlled Trial
Reduced pain and analgesic use after acoustic binaural beats therapy in chronic pain - a double blind randomized control cross-over trial.
Binaural Beats (BB) consist of two artificial acoustic stimuli with different frequency, presented simultaneously but independently to each ear. The human brain perceives and synchronizes to this frequency difference (entrainment). Aim of this study was to test the hypothesis that brain entrainment to a lower function rhythm, with BB application, can decrease pain perception and analgesic medication use, in chronic pain patients. ⋯ This study provides evidence that theta rhythm binaural beats can alleviate pain intensity, both after a brief 30 minute and a longer one week on-demand intervention. The subsequent significant reduction in analgesic medication consumption in chronic pain patients' daily living could offer a valuable tool, augmenting the effect of existing pain therapies.
