Effects of M-Cube Wave Versus Low-Frequency Neuromuscular Electrical Stimulation on the Strength and Thickness of the Quadriceps Muscles: A Within-Subject Comparison in Healthy Young Adults.

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 and objectives This study compared the effects of M-cube wave and conventional low-frequency neuromuscular electrical stimulation (NMES) on the strength and thickness of quadriceps muscles in healthy young men using a within-subject design. Materials and methods This study included 15 untrained, healthy young adults. Each participant received two NMES protocols: an M-cube wave protocol on the quadriceps and low-frequency stimulation on the contralateral side. Sessions were performed twice per week for six weeks. Muscle strength was assessed using isometric or concentric maximal voluntary contraction (MVC-ISO and MVC-CON) torque. Muscle thickness of the rectus femoris, vastus lateralis, and vastus intermedius, and subcutaneous fat thickness were measured using ultrasonography. Results Both protocols significantly increased the strength (MVC-ISO: 18.9% vs. 23.3%; MVC-CON: 35.1% vs. 44.8%) and thickness of the quadriceps muscles across all examined muscles. No significant differences were observed between the two NMES waveform protocols. Both groups showed reduced thickness of the subcutaneous fat in the lateral thigh. Conclusion M-cube wave and conventional low-frequency NMES protocols effectively improved the strength and muscle morphology of the quadriceps muscles in healthy young men. These findings support the use of waveforms in clinical and rehabilitative settings, with waveform selection tailored to individual needs and comfort.
