Randomized Controlled Trial
Pharmacological management of chronic low back pain in older patients: a randomized controlled trial of the effect of pregabalin and opioid administration.
Pregabalin and opioids are used to treat chronic low back pain (LBP). No previous investigations have compared the efficacy of pregabalin and that of opioids for chronic LBP. ⋯ Aside from screening tests, consideration of neuropathic pain and lower extremity symptoms may be an integral component in the selection of the appropriate medication for chronic LBP. Moreover, the therapeutic objectives, including pain relief and/or improvement of ADL, should be specified.

Inconsistent reporting of outcomes in clinical trials of patients with non-specific low back pain (NSLBP) hinders comparison of findings and the reliability of systematic reviews. A core outcome set (COS) can address this issue as it defines a minimum set of outcomes that should be reported in all clinical trials. In 1998, Deyo et al. recommended a standardized set of outcomes for LBP clinical research. The aim of this study was to update these recommendations by determining which outcome domains should be included in a COS for clinical trials in NSLBP. ⋯ The following outcome domains were included in this updated COS: 'physical functioning', 'pain intensity', 'health-related quality of life' and 'number of deaths'. The next step for the development of this COS will be to determine which measurement instruments best measure these domains.

PT and PI-LL sometimes offer limited utility in daily practice when evaluating QOL, especially in outpatient clinics with limited time and equipment facility. This study proposes a novel spino-pelvic parameter, lumbo-femoral angle (LFA). The purpose of this study is to analyze the correlation between LFA and HRQOL in adult scoliosis patients. ⋯ LFA could be considered a novel, user-friendly sagittal parameter, correlated with previously established sagittal spino-pelvic parameters and HRQOL measurements. LFA showed high inter- and intra-observer reliability, faster measurement times and could be easily identified and read. Mean LFA in asymptomatic adult patients was nearly 0° with 95 % CI value of -7° to 7°, and significantly increased in adult scoliosis patients.

Little information is available on the relationship between cervical sagittal alignment and health-related quality of life (HRQOL) in ankylosing spondylitis (AS) patients. The aim of this study was to identify relationships between cervical sagittal alignment and HRQOL in AS. ⋯ Cervical sagittal parameters were found to be significantly different in AS patients and normal controls. Correlation analysis revealed significant relationships between radiographic parameters and QOL. In particular, C2-C7 SVA was found to be a significant predictor of QOL in AS patient.

Comparative Study
Comparison of radiographic sagittal spinopelvic alignment between skeletally immature and skeletally mature individuals with Scheuermann's disease.
The aim of this study was to compare radiographic sagittal spinopelvic parameters between skeletally immature and skeletally mature patients with Scheuermann's disease (SD). ⋯ There is no significant difference in sagittal spinopelvic parameters between skeletally immature and mature subjects with SD. Pelvic incidence in both groups of SD patients was significantly lower than PI in normal children, adolescents, and adults. This challenges the role of PI in predicting desired LL in patients with SD.
