-
A retrospective case-control study. ⋯ Both CMCT and PCT are often prolonged in compressive lesions of the epiconus and conus medullaris, and MEP latency and CMCT are useful in the diagnosis.
-
Retrospective cohort study. ⋯ Level III.

Observational Study
Temporal Trends in the Epidemiology of Lower Back Pain in the United States.
This was an observational study. ⋯ Although there has been progress in reducing the impact of LBP in the United States, the Midwest region has greater rates for all measures compared with other US regions. Further, females and those aged 25 to 49 in the Midwest were more likely to be affected by LBP compared with counterparts in other regions. Future studies should identify specific factors contributing to elevated LBP rates in the Midwest in order to guide targeted interventions to reduce the incidence and burden of LBP there.

Randomized Controlled Trial
Immediate Correction of Idiopathic Scoliosis with Nighttime Braces Created by A fully-automated Generative Design Algorithm: A Randomized Controlled Crossover Trial.
Single-center, double-blinded, prospective crossover randomized controlled trial. ⋯ Level 2.
-
Retrospective review of a single institution cohort. ⋯ ADI and SVI quartile assignment were predictors of MCID achievement. While ADI and SVI may both identify patients at risk for adverse outcomes following lumbar fusion, SVI offers greater granularity in terms of isolating themes of disadvantage impacting MCID achievement.
