Tuina Alleviates Anxiety-Like Behaviors Associated With Neuropathic Pain Through the Modulation of Synaptic Plasticity in the Anterior Cingulate Cortex.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundAs the disease progresses, neuropathic pain (NP) is often accompanied by anxiety-like behaviors, which are associated with plastic changes in the synaptic structure and function within the anterior cingulate cortex (ACC). Tuina is a traditional Chinese manual therapy. This study aims to investigate the effects of Tuina on pain behaviors and related anxiety-like behaviors in rats with the chronic constriction injury (CCI) model, as well as its impact on synaptic plasticity in the ACC.
methodsThe rats were randomly divided into three groups: Sham, CCI, and Tuina. An NP comorbid anxiety model was established by inducing CCI in the right sciatic nerve. The pain-related behaviors and anxiety-like behaviors in rats were assessed using the mechanical withdrawal threshold (MWT), thermal withdrawal latency (TWL), open field test (OFT), and elevated plus maze (EPM). Supplementary Material The changes in the synaptic ultrastructure within the ACC were examined using transmission electron microscopy (TEM). The changes in excitatory synaptic transmission (synaptic function) within the ACC were investigated using the whole-cell patch-clamp technique. The expression levels of the postsynaptic proteins PSD-95, GluN2B, GluR1, and CaMKII in the ACC were analyzed using Western blot.
resultsTuina significantly elevated the pain threshold in CCI rats and mitigated their anxiety-like behaviors. Tuina alleviated the abnormal remodeling of synaptic structures in the ACC and mitigated the CCI-mediated enhancement of excitatory synaptic transmission. Tuina may exert its analgesic and anxiolytic effects by modulating the expression of postsynaptic proteins PSD-95, glutamate receptor GluN2B, GluR1, and the downstream protein CaMKII in the ACC.
conclusionTuina effectively alleviates pain sensitivity and anxiety-like behaviors in CCI model rats while modulating abnormal synaptic remodeling in the ACC. This study provides fundamental experimental evidence supporting Tuina as a potential therapeutic option for NP associated with anxiety-like behaviors.
