Real-Time Location System Assessment of Early Postoperative Recovery After Lumbar Decompression According to Surgical Approach.
Article in Neurospine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To evaluate early postoperative mobility after lumbar decompression using real-time location system (RTLS)-derived objective metrics and to explore differences in mobility patterns between biportal endoscopic decompression and open decompression. Methods: This retrospective cohort study included 323 patients who underwent lumbar decompression for degenerative lumbar spinal stenosis between March 2020 and May 2024. RTLS sensors embedded in wristbands continuously recorded patient mobility during postoperative days (PODs) 1-4. Primary RTLS-derived outcomes included total walking distance, mean walking speed, and active movement ratios (top 20% and top 50%). Between-group comparisons were performed using nonparametric tests. Propensity score matching and multivariable median quantile regression adjusting for age, American Society of Anesthesiologists physical status, and preoperative mobility were conducted. Results: RTLS identified differences in early postoperative activity patterns between surgical approaches. In adjusted analyses, activity-intensity-based metrics, particularly the top 20% activity ratio, remained significantly higher in the biportal endoscopic decompression group across multiple PODs. Subgroup analyses demonstrated minimal differences after single-level decompression, whereas activity-based differences were more frequently observed in multilevel procedures. Conclusion: RTLS-based continuous monitoring detected differences in early postoperative activity patterns following lumbar decompression. These findings support the role of RTLS as an objective tool for assessing early functional recovery in spine surgery.
