We implemented a sciatic nerve injury (SNI) model. At dthe mid-thigh level, sciatic nerves were exposed and crushed for 5\u202fs using non-serrated forceps at points spaced approximately 2\u202fmm apart. Postoperatively, Tuina therapy (Chinese therapeutic massage, Tuina) was administered to evaluate its neuromodulatory effects. SNI models were established in the SNI and TUI cohorts. TUI cohorts applied with \u201cThree-Manipulation and Three-Acupoint\u201d technique, which included pressing, plucking, and kneading on the acupoints Yinmen (BL37), Chengshan (BL57), and Yanglingquan (GB34). The control cohort underwent no intervention. The sham surgery and model cohorts underwent restraining interventions. Motor function was assessed using Basso, Beattie, and Bresnahan (BBB) scores and CatWalk gait analysis. Spinal cord (SC) histology was evaluated using hematoxylin and eosin and Nissl staining. NeuN-positive cells were quantified via immunofluorescence. Tumor necrosis factor-<jats:italic>\u03b1<\/jats:italic> (TNF-\u03b1), interleukin-6 (IL-6), and aquaporin-4 levels were determined through enzyme-linked immunosorbent assay. RhoA, ROCK2, Bax, Bcl-2, and cPLA2 mRNA levels were analyzed using real-time quantitative polymerase chain reaction. RhoA, ROCK2, Bax, Bcl-2, cPLA2, and p-cPLA2 protein expressions were analyzed using western blotting to investigate the impact of Tuina therapy on nerve regeneration and apoptosis regulation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The TUI cohort showed better BBB scores and CatWalk results than the SNI cohort (all <jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001). Histological analysis revealed diminished inflammatory cell infiltration and increased neuronal survival. NeuN immunofluorescence indicated decreased motor neuron apoptosis in the anterior horn of the SC.
