Lumbosacral orthosis can improve postural control in older adults with chronic low back pain.
Trial report in BMC musculoskeletal disorders, 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
backgroundOlder adults with chronic low back pain may report poor postural control and increased fall risks. Possible key mechanisms are altered lumbar spine proprioception, stiffness and mobility, which could be enhanced through lumbar stabilization approaches. The purpose of this study was thus to evaluate the immediate effects of two lumbar stabilization approaches on postural control measures, namely a lumbosacral orthosis and the abdominal drawing-in maneuver.
methods57 older adults (> 65 yrs): 22 with chronic low back pain and 35 healthy controls performed two trials (30 s) of a semi-tandem balance task on a force platform, while three experimental conditions were randomly assessed: (1) control (without lumbar stabilization), (2) lumbosacral orthosis, and (3) the abdominal drawing-in maneuver. Linear variables derived from the platform center of pressure were computed (mean amplitude, ellipse area, sway velocity, and frequency) as outcomes.
resultsNo group × condition interactions were significant. However, chronic low back pain individuals showed significantly (p ≤ 0.03) poorer postural control than healthy controls for 3/7 center of pressure parameters. Significant experimental condition effects (p<0.01) were also observed. The lumbosacral orthosis reduced center of pressure sway as compared to control (13%) and the abdominal drawing-in maneuver (15%) mainly for sway center of pressure velocity, while the abdominal drawing-in maneuver deteriorated postural control (23 to 39%) comparatively to the other two conditions.
conclusionLumbosacral orthosis improved postural control across some center of pressure parameters, while the abdominal drawing-in maneuver degraded performance. These results have implications for clinical decision-making to promote fall prevention and sustainable health for older adults with and without chronic low back pain.
