Core muscle strength can be reliably measured using a novel isokinetic device: An intra-observer study.
Article in Journal of back and musculoskeletal rehabilitation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundCore strength is an important aspect of physical fitness. A dynamometer was developed to measure isokinetic core muscle strength in multiple planes of motion. Establishing the reliability is needed before it can be used in practice.
objectiveExamine the intra-observer reliability of a trunk isokinetic dynamometer.
methods31 participants were recruited. Tests were performed twice with an interval of 5-9 days by the same observer. Testing included rotation, flexion/extension and lateral flexion at speeds of 90∘/s and 60∘/s. The main outcome measure was peak torque (PT). The secondary outcomes included peak torque angle (PTA), time to peak torque (TTPT) and compensatory torques (CompTQ). The intra-observer reliability was investigated using intraclass correlation coefficients (ICC).
resultsPeak torque reliability was good to excellent (ICC = 0.70-0.91), whereas the reliability of the PTA (ICC =-0.04-0.56) and TTPT (ICC = 0.01-0.68) were poor to moderate. CompTQ reliability was moderate to good (ICC = 0.20-0.88).
conclusionsThe intra-observer reliability of the isokinetic measurement of core strength peak torque was good. The secondary outcomes peak torque angle and time to peak torque were less reliable and the compensatory torques showed moderate to good reliability. This isokinetic dynamometer could have useful applications in the field of sports medicine and rehabilitation.
