目的观察针刺推拿中药综合治疗颈性眩晕的疗效。方法设综合组80例、电针组42例、推拿组68例和中药组36例,进行疗效比较分析。结果综合组有效率为93.8%,电针组有效率为73.8%,推拿组有效率为86.8%,中药组有效率为69.4%,综合组有效率与其他几组比较差异均有统计学意义(P〈0.05)。结论采用电针、推拿、中药相结合的综合疗法治疗颈性眩晕集诸单一疗法之精华,避免单一疗法的局限性,可提高有效率。 相似文献

不同眩晕证型两侧脑血流速度差变化与症状的关系研究 总被引:1,自引:0,他引:1
目的:为了观察不同眩晕证型中的脑血流速度差大于正常与临床症状之间的关系。方法:应用经颅多普勒超声检查方法,观察颅底各个相对应大血管血流速度两侧差值的变化。结果:各种不同眩晕证型之间的差值有非常显著性的差异,各个指标之间均存在着不同的差异,这些差异性的变化多数与临床表现的头痛有着密切的关系。结论:使用此方法可以更早期地评价不同眩晕证型脑血管功能状态的水平,以便为临床提供可靠的诊断依据。另一方面也充分地说明了经颅多普勒超声对脑血管功能的观察是一项十分敏感的观察指标。 相似文献

Objective: This international postmarketing observational study of flunarizine was designed to evaluate, in routine clinical practice,
the risk/benefit ratio of flunarizine in its approved indications, namely prophylaxis of migraine and treatment of vertigo.
Comparator drugs were propranolol in migraine and betahistine in vertigo. The study was carried out by 498 general practitioners
in Belgium, The Netherlands and Germany, whose participation had been requested by mail. In total 3186 patients were entered:
1601 in the two migraine cohorts and 1585 in the two vertigo cohorts.
Results:
In the migraine study, treatment results with propranolol tended to be somewhat better than those with flunarizine, but a
selection bias cannot be excluded. There was no clear difference regarding efficacy between flunarizine and betahistine in
the vertigo study. The safety evaluation focused on extrapyramidal symptoms (EPS) and depression. Overall, EPS were noted
in only four patients, two in the vertigo-betahistine and two in the migraine-flunarizine cohort. A total of 70 patients developed
depressive symptoms (34 in the flunarizine and 24 in the propranolol migraine cohorts, but only 7 in the flunarizine and 5
in the betahistine vertigo cohorts). Patients with migraine were clearly more prone to depression than patients with vertigo,
regardless of their treatment. Additional risk factors for depression were a history of depression, and, in the migraine flunarizine
cohort, a high number of previous migraine treatments.

"Fatigue on Rest", headache, vertigo and the feeling of loss of balance, blurred vision, nausea, tension and irritability, were found to be prevalent amongst patients who had locally asymptomatic, unerupted impacted teeth. A comparative pressure sign was developed, which, when positive, confirmed the relationship between the impacted teeth and the medical symptoms. Removal of the impactions resulted in the alleviation of the symptoms. Stress and psychogenic factors are considered as trigger mechanisms, rather than as basic causes of the symptoms. 相似文献
