To determine whether there is an association between preoperative 10-Item Patient Activation Measure (PAM-10) scores and clinical outcomes following MIS LD. ⋯ Lower preoperative PAM scores were associated with worse improvement in clinical outcomes following MIS LD. Patients with lower PAM scores had diminished improvement in long-term patient-reported outcomes including ODI, SF-12, and VAS back and leg pain. Our investigation suggests that preoperative PAM assessments may be an effective tool to predict postoperative outcomes following MIS LD.

To identify age-related changes and the relationship between upper and lower cervical sagittal alignment and the range of motion (ROM). ⋯ The O-C2 angle gradually decreased and the C2-7 angle increased with age. The ROM of the O-C2 angle did not change, but the ROM of the C2-7 angle decreased with age. The upper and lower cervical spine showed different age-related changes.

The purpose of this study is to evaluate the performance of a novel deep learning (DL) tool for fully automated measurements of the sagittal spinopelvic balance from X-ray images of the spine in comparison with manual measurements. ⋯ The differences between measurements are in the range of the observer variability of manual measurements, indicating that the DL tool can provide clinically equivalent measurements in terms of accuracy but superior measurements in terms of cost-effectiveness, reliability and reproducibility.

A nonrandomized, prospective, concurrent control cohort study. ⋯ ADS patients have larger CoE dimensions and increased sway when compared to non-scoliotic controls. ADS patients rely on a hip balance control "strategy" and lower extremity RoM to maintain balance, which differed from control subjects. Unlike prior attempts to define compensatory mechanisms in ADS patients, the described technique utilizes dynamic, three-dimensional measurements to define what is occurring within the CoE. By expanding on prior CoE measurements, we were able to define a unique dynamic balance control strategy for each patient.
