CAMK2G and Spasticity: <h4>Background</h4>This study investigated whether manual therapy applied to tendon organs ameliorated neuromuscular dysfunction in rats with spasticity induced by upper motor neuron injury associated with spastic cerebral palsy, and analyzed the potential involvement of the C-fiber-mediated CaMKII signaling pathway.<h4>Methods</h4>Male rats were used to establish palsy models and divided into groups: Control, Model, Manual Therapy (MT), Capsaicin Treatment, Sham, CaMKII Inhibitor, and DMSO Solvent groups.
