Effects of Single-Joint Type Hybrid Assistive Limb in Knee Rehabilitation on Reduction of Pre-motor Time and Increased Rate of Fast Muscle Activation for Anterior Cruciate Regiment (ACL) Reconstruction.

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
BACKGROUND/
objectivesChanges in muscle characteristics after post-anterior cruciate regiment (ACL) reconstruction are common. Knee robotic-assisted therapy using hybrid assistive limb (HAL) single-joint training for recovery from ACL injury has the potential to optimize muscle activity; however, its neurophysiological effects remain unclear. Thus, this study aimed to explore the electrophysiological parameters.
methodsThis prospective, nonrandomized, controlled trial was conducted between December 2021 and January 2024. The patients were divided into two groups: the HAL group and the control group, each including five patients who underwent arthroscopic ACL reconstruction. Knee HAL single-joint training was conducted once weekly for three sessions. Three electrophysiological measures were examined related to knee neuromuscular responses pre-motor time, peak amplitude time, and neuromuscular rate of electromyography rise (RER) using surface electromyography (EMG). The pre-motor time and peak amplitude time were assessed in both groups at each session pre- and post-intervention. Both groups were evaluated for RER at postoperative weeks 17 and 21.
resultsRegarding the interaction of pre-motor time within each group, the interaction of pre-motor time within each group, the effect size of vastus medialis (VM) was larger in the HAL group. The peak amplitude time of EMG, the overall estimated marginal means, and the HAL group exhibited a significant difference in the VM (p=0.019), while vastus lateralis (VL) showed no significant difference but a larger effect size (d=0.61). The RER revealed a significant difference in semitendinosus-RER30ms in the HAL group (p=0.044).
conclusionsThe knee HAL training for post-ACL reconstruction patients may influence neurophysiological outcomes.
