Abstract
Objective: To explore the clinical efficacy of core stability training of the lumbodorsal muscles combined with dynamic joint mobilization in patients with sacroiliac joint dysfunction. Methods: From October 2023 to December 2025, 38 patients with sacroiliac joint dysfunction were randomly divided into a training group (n = 13), a treatment group (n = 12), and a combined intervention group (n = 13). The training group received core stability training of the lumbodorsal muscles, the treatment group received Mulligan’s technique, and the combined intervention group first received core stability training of the lumbodorsal muscles followed by Mulligan’s technique. Before treatment and after six weeks of treatment, evaluations were conducted using the Numeric Pain Rating Scale (NPRS), the Oswestry Disability Index (ODI score), lumbar range of motion (ROM), and pressure pain threshold (PPT). Results: After six weeks of treatment, both the treatment group and the combined intervention group showed a decrease in NPRS scores compared to before intervention (P < 0.05). All three groups showed a decrease in ODI scores compared to before intervention (P < 0.05), with the combined intervention group having lower NPRS scores than the training group (P < 0.05) and lower lumbar extension ROM than the treatment group (P < 0.05). Conclusion: Core stability training of the lumbodorsal muscles combined with dynamic joint mobilization can effectively alleviate pain and improve dysfunction in patients with sacroiliac joint dysfunction, demonstrating good clinical application value.
