Evaluation of the biomechanics of lower limbs in normal, overweight, and obese people using the SMART F-IMU system.
Article in Scientific reports, 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
This study provided a pilot evaluation and proof of concept for the proposed SMART F-IMU system, designed to investigate gait characteristics in normal-weight (NW) and overweight/obese (OW/OB) participants. This system combined modified inertial measurement units (IMUs) and flexible force sensors to provide estimates of ground reaction force (GRF), joint angles, and spatiotemporal gait parameters. The SMART F-IMU appeared to address the limitations of traditional gait analysis methods, enabling convenient and affordable assessments in real-world settings. The OW/OB group exhibited significantly longer stride, stance, swing, double support, and cycle times, alongside decreased cadence and swing phase percentages, all demonstrating large effect sizes (> 1.0). Statistical significance (p < 0.01) and large effect sizes (> 0.8) were observed in the hip angle at initial contact, knee maximum extension angle in the stance phase, knee angle at toe-off, knee maximum flexion angle in the swing phase, ankle maximum plantarflexion angle in the pre-swing phase, hip adduction angle in the terminal stance, knee maximum adduction angle in the stance phase, and knee maximum adduction angle in the swing phase. This study's results demonstrated the feasibility of the SMART F-IMU for detecting weight-induced gait alterations in non-laboratory settings, highlighting its potential for longitudinal monitoring of joint biomechanics during daily activities.
