Effects of gait speed on paraspinal muscle activation: an sEMG analysis of the multifidus and erector spinae.
Article in PeerJ, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: The paraspinal muscles, such as the multifidus muscles and erector spinae muscles, play an important role in trunk stabilization and pelvic mobility during gait. Understanding how they are activated according to the speed of locomotion can facilitate the diagnosis and treatment of patients with these conditions. This study aimed to comprehensively analyze the activity of postural muscles (multifidus and erector spinae) using surface electromyography (sEMG) across a range of gait speeds. Methods: The study group consisted of 31 students of physiotherapy at the Pomeranian University in Słupsk, including 20 women (64.51%) and 11 men (35.48%). The research process included an interview and participation in the sEMG survey. The sEMG examination of the musculus erector spinae (MES) and musculus multifidus (MM) was carried out in the supine, standing position, while walking on a treadmill, maintaining speeds: 1 km/h, 3 km/h, 5 km/h and 6 km/h, for 60 s at each stage and at maximum voluntary isometric contraction (MVIC). The percentage value of the amplitude of the sEMG recording in relation to maximum voluntary isometric contraction (%MVIC) was determined. The average rate of change in muscle activity was also assessed in relation to the respective changes in locomotion speed for MES and MM. Results: The results show significant differences in the %MVIC parameter between sides (left Conclusions: In the sEMG examination during rest, standing and walking, the activity of the right and left MES and MM muscles examined is not always equal. The activity of the muscles studied (MES and MM) increases with increasing gait speed. The rate of change in muscle activity decreases as gait speed increases.
