Frequency-specific neuromuscular adaptations: comparative effects of high- and low-frequency neuromuscular electrical stimulation on muscle function and quality.

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
This study investigated the frequency-specific effects of high- and low-frequency neuromuscular electrical stimulation (NMES) on neuromuscular function and muscle quality. Sixteen healthy young males were randomly assigned to either a high-frequency stimulation group (HFES, 100 Hz; n=8) or a low-frequency stimulation group (LFES, 50 Hz; n=8) for 6 weeks of NMES intervention. Neuromuscular function was assessed using maximum voluntary isometric contraction (MVIC), while muscle quality of the rectus femoris (RF) and vastus lateralis (VL) was evaluated via ultrasound echo intensity (EI). Assessments were taken at baseline, midintervention (week 3), and postintervention (weeks 6, 8 and 10). HFES significantly increased MVIC during the intervention, indicating an immediate neuromuscular improvement. In contrast, LFES showed delayed effects, with significant EI improvements in RF and VL emerging only after the intervention ended. Statistical analysis revealed a significant interaction effect between time and intervention for MVIC and EI, highlighting the frequency-dependent nature of NMES adaptations. These results suggest that NMES induces neuromuscular adaptations in healthy adult males, with HFES promoting immediate gains and LFES leading to delayed benefits. Thus, frequency selection is critical in designing effective NMES protocols.
