Reliability study. ⋯ Our study has demonstrated that the intrarater reliability for the instrument to assess MCC and MSCC in the setting of traumatic SCI was high. The interrater ICCs at a moderate level of reliability combined with our results using analysis of variance with post hoc tests indicate that the measurements of MCC and MSCC are reproducible, which supports the use of these radiologic parameters in the clinical and research settings.

Randomized Controlled Trial Multicenter Study
Fear avoidance beliefs do not influence disability and quality of life in Spanish elderly subjects with low back pain.
Correlation between previously validated questionnaires. ⋯ In Spanish institutionalized elderly subjects, FABs only have a minor influence on physical quality of life, and none on disability or mental quality of life. In elderly subjects with LBP, differences in FABs are not associated with differences in disability or quality of life. Further studies should explore the potential value of FABs in the elderly in other settings.

Randomized Controlled Trial Multicenter Study
Are back supports plus education more effective than education alone in promoting recovery from low back pain?: Results from a randomized clinical trial.
Randomized clinical trial. ⋯ Although there was no overall effect on self-reported recovery or administrative measures or lost work time between the study groups, a back support plus health education may have some value in preventing recurrent WR-LBD in industrial workers who work in psychosocial environments and perform manual material handling tasks similar to those found in parts distribution centers.

Multicenter Study Comparative Study
A pedicle screw construct gives an enhanced posterior correction of adolescent idiopathic scoliosis when compared with other constructs: myth or reality.
Tricenter retrospective cohort study of 72 patients who underwent posterior correction of Lenke 1 adolescent idiopathic scoliosis (AIS). Each center represented a single surgeon using only one type of construct. ⋯ The Group 3 (pedicle screw only) construct did not give an enhanced correction of Lenke 1 AIS, when the preoperative flexibility of the curve was considered. Also, contrary to popular belief, the pedicle screw construct has a lordosing effect on the thoracic spine. Therefore, we think that there is no significant advantage in using a relatively expensive pedicle screw construct in the correction of Lenke 1 AIS.

Multicenter Study Comparative Study
Construct validity of the physical function scale of the Swiss Spinal Stenosis Questionnaire for the measurement of walking capacity.
Measurement (validity) study using data from a prospective longitudinal study of lumbar spinal stenosis. ⋯ Results support construct validity of the Physical Function Scale for the measurement of walking in an lumbar spinal stenosis population. However, it cannot be ascertained from the current study that the construct being measured is, indeed, walking capacity. Further research is warranted to investigate criterion validity evidence for the use of the Physical Function Scale in the measurement of walking capacity in lumbar spinal stenosis, by examining the relationships between self-report and observational measures of walking.
