1 · What the graph read from it

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.

2 · The registry

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

Knee osteoarthritis (KOA) is a common degenerative joint disease that significantly reduces mobility and quality of life in elderly populations. Tai Chi, a low-impact mind-body exercise, has been suggested as a potential non-pharmacological intervention for managing KOA, but its biomechanical effects remain unclear. This study aimed to evaluate the effects of a 14-week Tai Chi program on clinical symptoms, lower limb biomechanics, and muscle activation patterns in elderly patients with KOA. A single-blinded randomized controlled trial was conducted, enrolling 24 participants aged 55-70 years with unilateral KOA. Participants were randomly assigned to a Tai Chi intervention group or a control group receiving health education only. Primary outcomes included joint range of motion, joint moments, and muscle activation, measured using a motion capture system and surface electromyography. Secondary outcomes, such as pain, stiffness, function (WOMAC), balance (BBS), and quality of life (SF-12), were also assessed pre- and post-intervention. The Tai Chi group demonstrated significant improvements in WOMAC pain (-1.58 ± 1.44 vs. 0.11 ± 0.78, p = 0.01), stiffness (-0.33 ± 0.78 vs. 0.56 ± 0.88, p = 0.02), and function scores (-2.58 ± 3.53 vs. 1.00 ± 2.78, p = 0.02) compared to the control group. Balance (BBS: 1.42 ± 1.88 vs. -0.89 ± 1.27, p = 0.01) and physical health (SF-12 PCS: 5.45 ± 6.76 vs. -1.05 ± 2.17, p = 0.01) were also enhanced. Biomechanically, Tai Chi reduced horizontal plane knee ROM (-3.03 ± 1.00°, p = 0.01) and maximum knee extension moments (affected side: -0.09 ± 0.04 N/kg, p = 0.04, Non-affected side: -0.11 ± 0.05 N/kg, p = 0.03). Tibialis anterior muscle activation increased significantly (5.66 ± 1.05%MVIC, p = 0.02), while other muscles showed non-significant trends. Tai Chi demonstrated significant clinical and biomechanical benefits for elderly KOA patients, suggesting its potential as a safe, accessible, and effective therapeutic intervention.
