Effect of repetitive transcranial magnetic stimulation on quadriceps function in participants in the early postoperative period after anterior cruciate ligament reconstruction: a randomized controlled trial.
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
backgroundInsufficient quadriceps activation is likely to occur in the early postoperative period after anterior cruciate ligament reconstruction (ACLR). Transcranial magnetic stimulation (TMS) has a positive effect on the activation and contractility of the quadriceps femoris. To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on quadriceps femoris function in participants during the early postoperative period following anterior cruciate ligament reconstruction (ACLR).
methodsFifty six participants received rehabilitation education and a recommended routine training and knee flexion and extension exercise plan. In addition to this, the REAL group received 2 weeks of transcranial magnetic stimulation treatment. The resting motor threshold (RMT), root mean square (RMS) value, difference in knee extension angle between the healthy and affected sides, visual analog scale (VAS) score, and difference in the circumference of the vastus medialis oblique between the healthy and affected sides were assessed at baseline and 2 weeks after treatment.
resultsCompared with those in the SHAM group, the improvements in the RMT and RMS value of the vastus medialis oblique, the difference in the knee extension angle between the healthy and affected sides, and the VAS score in the REAL group were more significant (p < 0.001). There was no significant between-group difference in the difference in the circumference of the vastus medialis oblique between the healthy and affected sides (p > 0.05).
conclusionThe use of rTMS, the goal of which is to increase the excitability of the corticospinal pathway, can promote the activation of the quadriceps femoris, prevent muscle atrophy, and accelerate the recovery of muscle strength in participants in the early postoperative period after ACLR.
