Synaptic plasticity in the spinal dorsal horn (SDH) is a key regulator of pain processing, wherein astrocytes play a central role. Regulation of N-myc downstream-regulated gene 2 (NDRG2) and glutamate transporter 1 (GLT-1) is particularly important in NP modulation. Accumulating evidence suggests that Tuina exerts analgesic effects by inhibiting aberrant synaptic plasticity. This study explored whether Tuina regulates synaptic plasticity through astrocytes to attenuate NP. Using an in vivo model, Tuina or the astrocytic inhibitor fluorocitrate was administered to a chronic constriction injury (CCI)-induced NP rat model for 14 days. Tuina significantly alleviated pain hypersensitivity in CCI rats, improved structural damage, suppressed astrocytic activation, reduced glutamate accumulation and restored the SDH's expression of proteins linked to synaptic plasticity. These effects were associated with inhibition of astrocytic NDRG2 and upregulation of GLT-1. Conversely, NDRG2 overexpression through AAV impaired Tuina's ability to promote glutamate transport, leading to glutamate accumulation, enhanced excitatory transmission and reduced analgesic efficacy. In conclusion, Tuina alleviates NP by modulating the astrocytic NDRG2/GLT-1 pathway, reducing synaptic glutamate levels and normalising synaptic plasticity. These findings provide new mechanistic insights into Tuina's analgesic action and have identified NDRG2/GLT-1 as a possible therapeutic target for NP treatment.  \n1 | Introduction  \nNeuropathic pain (NP), which usually presents as a chronic, recurrent and refractory illness, is characterised by spontaneous pain, hyperalgesia, and allodynia [1] . Epidemiological data suggest that NP affects 7%–10% of the population and constitutes 20%–25% of chronic pain cases. Its high prevalence, coupled with limited treatment efficacy, presents a major public health challenge [2] . First-line pharmacological options, such as gabapentin and tricyclic antidepressants, often provide only partial relief and are limited by adverse central nervous system  \neffects. This has spurred the need for safer and more effective alternatives. Among these, physical therapies such as thermotherapy for analgesia and relaxation, electromagnetic therapies for neuromodulation and photobiomodulation for tissue repair, alongside mechanical interventions such as traction, have been integrated into clinical practice with demonstrated benefits for some patients [3] . Nonetheless, their effectiveness varies substantially across individuals, which restricts broad applicability. Therefore, developing more comprehensive and multidimensional approaches to NP management remains crucial.  \nThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.  \n© 2026 The Author(s).
