Recruitment of discrete regions of the psoas major and quadratus lumborum muscles is changed in specific sitting postures in individuals with recurrent low back pain.
Cross-sectional controlled laboratory study. ⋯ The findings suggest a redistribution of activity between muscles that have a potential extensor moment in individuals with LBP. The modification of EMG of discrete fascicles of the PM and QL was related to changes in ES EMG signal amplitude recorded in sitting.

Randomized Controlled Trial Multicenter StudyThe working mechanism of manual therapy in participants with chronic tension-type headache.
Prospective longitudinal study. ⋯ Increased neck flexor endurance appears to be a working mechanism of manual therapy. This finding supports isometric training of neck flexors in participants with CTTH. Trial registered with Netherlands Trial Register (TR 1074).

Association between plantar fascia vascularity and morphology and foot dysfunction in individuals with chronic plantar fasciitis.
Single-cohort laboratory-based study. ⋯ Individuals with unilateral chronic plantar fasciitis demonstrated significantly greater vascularity and thickened fascia on the affected side compared to the unaffected side and also to healthy controls. Fascia vascularity was associated independently with self-perceived pain, and both fascia vascularity and thickness were associated with foot dysfunction in patients with chronic plantar fasciitis. Public trials registry: Current Controlled Trials, ISRCTN49594569.

Clinical, physical, and neurophysiological impairments associated with decreased function in women with carpal tunnel syndrome.
Cross-sectional study. ⋯ There were significant positive correlations between the functional status subscale score and pain intensity (r = 0.36, P<.001), depression (r = 0.32, P<.001), and duration of symptoms (r = 0.23, P = .005). Significant negative correlations were also observed between the functional status subscale score and pinch grip force of the index finger (r = -0.25, P = .002) and little finger (r = -0.28, P<.001), ROM in cervical flexion (r = -0.22, P = .003) and lateral flexion away from the side of CTS (r = -0.24, P = .002) and toward the side of CTS (r = -0.16, P = .045), and pressure pain threshold over C5-6 (r = -0.34, P<.001), the carpal tunnel (r = -0.35, P<.001), and the tibialis anterior muscle (r = -0.26, P<.001). Stepwise regression analyses revealed that pain intensity, thumb and little finger pinch grip force, severity of depression, and cervical ROM in lateral flexion away from the side of CTS explained 38.2% of the variance in functional status (R2 = 0.411, adjusted R2 = 0.382, F = 15.42, P<.001). CONCLUSION This study found that a number of modifiable factors are associated with self-reported function in women with CTS. Future longitudinal studies will help to determine the clinical implications of these findings.
