RESUMEN
Chronic low back pain (CLBP) is a highly prevalent condition worldwide and a major cause of disability. The majority of patients with CLBP are diagnosed with chronic non-specific low back pain (CNLBP) due to an unknown pathological cause. Manual therapy (MT) is an integral aspect of traditional Chinese medicine and is recognized as Tuina in China. It involves techniques like bone-setting and muscle relaxation manipulation. Despite its clinical efficacy in treating CNLBP, the underlying mechanisms of MT remain unclear. In animal experiments aimed at investigating these mechanisms, one of the main challenges is achieving normative MT on CNLBP model rats. Improving the stability of finger strength is a key issue in MT. To address this technical limitation, a standardized procedure for MT on CNLBP model rats is presented in this study. This procedure significantly enhances the stability of MT with the hands and alleviates common problems associated with immobilizing rats during MT. The findings of this study are of reference value for future experimental investigations of MT.
