[Clinical effect of lever positioning manipulation for lumbar disc herniation and its influence on Cobb angle]

Objective: To observe the clinical effect of lever positioning manipulation for the treatment of lumbar disc herniation and its effect on Cobb angle.

Methods: From December 2017 to November 2018, 67 patients with lumbar disc herniation were included in the study. The patients were randomly divided into treatment group and control group by digital table method. There were 34 cases in the treatment group, including 20 males and 14 females, with an average age of (36.09±8.26) years old and a course of (13.79±15.50) months. Treatment group was treated with lever positioning manipulation. There were 33 cases in the control group, including 18 males and 15 females, with an average age of(36.48±7.81) years old and a course of (12.82±15.68) months. Control group was treated with lumbar slanting manipulation. Two groups were treated 3 times a week, once every other day, 6 times for a course of treatment, after 2 courses of treatment, the changes of Cobb angle before and after treatment were compared between two groups by imaging. The symptoms and signs were scored with reference to clinical evaluation standard;overall efficacy was evaluated with reference to "Diagnostic Efficacy Criteria of Traditional Chinese Medicine Syndrome" issued by the State Administration of Traditional Chinese Medicine for lumbar disc herniation.

Results: One patient in each group dropped out. The symptom and sign scores of treatment group and control group before treatment were 18.56± 4.81, 18.61±3.72, while after treatment were 9.41±5.19, 13.55±3.68;treatment group was significantly lower than control group after treatment (P<0.05). The rate of overall efficacy of treatment group and control group were 97.06% and 75.76%, respectively, and treatment group was superiorto control group(P<0.05). Post treatment Cobb angle of both groups of patients became smaller(P<0.05). The Cobb angle of treatment group and control group were(17.95±4.45)°, (18.14±3.59)° before treatment, while after treatment were (18.14±3.59)°, (15.49±1.75)°, change of Cobb angle in treatment group was better than in controlgroup(P<0.05).

Conclusion: Both the lever positioning manipulation and the lumbar slanting manipulation methods are effective for the treatment of lumbar disc herniation, but clinical effect of lever positioning method on lumbar disc herniation is more significant, and the effect on Cobb angle is more obvious. It is worthy of promotion.
