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.

Multicenter Study
Predictors of change in postoperative pulmonary function in adolescent idiopathic scoliosis: a prospective study of 254 patients.
A multicenter study of prospectively collected pulmonary function testing and radiographic measures in patients surgically treated for adolescent idiopathic scoliosis (AIS). ⋯ Aside from preoperative PFT values, open anterior approaches predict the largest percent of variance in 2-year PFT. Additionally, a clinically significant reduction in the predicted 2-year pulmonary function is more likely when performing a thoracoplasty. The magnitude of the effects for both these variables, however, is modest. This may facilitate the decision-making process as regards to operative intervention.

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.

A cross-sectional survey of households selected using multistage stratified sampling. ⋯ Chronic spinal pain is a common problem in the Nigerian community, and persons 60 years of age and older may be at particularly elevated risk. Chronic spinal pain is associated with increased probability of comorbid physical and mental disorders. These comorbid conditions partly but do not fully explain the disability associated with chronic spinal pain, which therefore constitutes a substantial health burden on the society.
