Objective:To observe the effect of subtle adjustment of the cervical spine combined with Shu Jing Ding Xuan (Neck-relaxing and Dizziness-alleviating) Decoction for cervical vertigo. 〈br〉 Methods:An open-label, randomized and parallel controlled clinical study was designed. Subtle adjustment of the cervical spine combined with Shu Jing Ding Xuan (Neck-relaxing and Dizziness-alleviating) Decoction was used for patients in the treatment group, whereas subtle adjustment alone was used for patients in the control group. The results in the two groups were statistically analyzed after two courses of treatment. 〈br〉 Results:The recovery rate and total effective rate in the treatment group were 20.6%and 88.2%respectively, versus 14.7%and 73.5%in the control group. The inter-group differences were statistically significant (both P&lt;0.01). 〈br〉 Conclusion: Subtle adjustment of the cervical spine combined with Shu Jing Ding Xuan (Neck-relaxing and Dizziness-alleviating) Decoction is better than subtle adjustment alone for cervical vertigo. 展开更多

OBJECTIVE:To evaluate the effectiveness of a combined Traditional Chinese Medicine(TCM) therapy versus conventional treatment on adolescent idiopathic scoliosis.METHODS:One hundred twenty outpatients with mild and moderate adolescent idiopathic scoliosis were randomly divided into a TCM group(TCMG)and a brace group(CG).TCMG patients underwent Daoyin,Tuina,and acupotomology therapies.CG patients were treated with a Milwaukee brace.Each patient's Cobb angle was measured after 12 and 24 months of treatment,and pulmonary function was determined after 12 months of treatment.Average electromyogram(AEMG) ratio of the surface electromyogram was measured after 6 and 12 months of treatment and followed-up after 18 and 24 months.RESULTS:The Cobb angle significantly decreased in both groups after 12 months of treatment compared with before treatment(P< 0.05).The percentages of original Cobb angle in TCMG and CG were51.4%and 47.8%(P > 0.05) after 12 months and62.5%and 34.7%(P < 0.05) after 24 months,respectively.Pulmonary function significantly improved after 12 months in TCMG(P < 0.05) but significantly decreased in CG(P < 0.05).The AEMG ratio was significantly lower(P < 0.01) and tended to remain at1 after stopping treatment in TCMG,but increased in CG(P<0.05).CONCLUSION:TCM combined therapy can prevent the progression of scoliosis.The AEMG ratio is a promising index that could replace radiography in the evaluation of treatment effect and progression in scoliosis. 展开更多
