Meniscal stress biomechanics in Tai Chi's Brush knee and Twist Step for elderly.

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
Objective: This study investigates the biomechanical effects of long-term Tai Chi practice on the knee meniscus through biomechanical experimentation and finite element simulation, focusing on practitioners performing Knee Brushing and Twisting Step. The findings aim to establish scientific guidelines for optimizing exercise protocols in middle-aged and elderly populations. Methods: Twenty male middle-aged and elderly practitioners were recruited, divided into a Beginner Group (BG: n = 10), and an Experienced Group (EG: n = 10). Kinematic and kinetic data during Knee performance of Brushing and Twisting Step were collected using synchronized three-dimensional infrared motion capture and force platforms. A finite element model was developed and validated based on knee CT and MRI imaging data from a representative participant with average anthropometric measurements. The acquired kinematic and kinetic data were applied as boundary conditions and loading inputs in finite element analysis software to simulate the knee joint contact stress distribution during movement execution. Results: (1) The Experienced Group demonstrated significantly greater knee flexion angles compared to the Beginner Group across all movement phases ( Conclusion: Long-term practice of Tai Chi optimizes the distribution of stress across the knee joints, effectively reducing localized stress concentrations and the associated risks of meniscal injuries. For novice practitioners, it is crucial to emphasize precision in movement and adherence to technical standards to prevent knee injuries that may arise from improper biomechanical loading patterns.
