Abstract:

Objective To explore the imbalance of paravertebral muscle group for patients with unilateral lumbar disc herniation.

Methods From January, 2022 to January, 2023, 30 patients with unilateral lumbar disc herniation (observation group) and 30 healthy people matching in general data (control group) were measured the tension and stiffness of multifidus and erector spinae with MyotonPRO, while the observation group was assessed with Visual Analogue Scale (VAS) for pain and Japanese Orthopaedic Association (JOA) score, and the time of disease was also recorded.

Results The mean of bilateral tension and hardness of multifidus and erector spinae was more in the observation group than in the control group (|t| > 5.407, P < 0.001), and the tension and hardness of multifidus and erector spinae of the affected side were more than those of the unaffected side in the observation group (|t| > 11.219, P < 0.001). The tension and hardness of multifidus and erector spinae of the affected side were positively correlated with VAS score (r > 0.942, P < 0.001), and negatively correlated with JOA score (|r| > 0.886, P < 0.001).

Conclusion The tension and hardness of multifidus and erector spinae of the affected side increase after unilateral lumbar disc herniation, resulting in asymmetry.

Key words: lumbar disc herniation, multifidus, erector spinae, muscle tension, muscle hardness
