Based on the principle of completeness, Qigong is described as a method uniting external and internal paths to insight, and this can be perceived while practicing it. The common principle which we approach in every Qigong exercise is named the Dao. In quantum physics, there are also phenomena showing an underlying unity: entanglement of atomic systems.  相似文献

Background

The German Acupuncture Trials (GERAC) have brought good results regarding the acupuncture treatment of lumbago and headache. However, for reasons of scientific practicability, patients included in these trials were restricted by certain criteria (among others, excluding patients after spinal surgery, past experiences with acupuncture, patients with ischialgia). Also, microsystems and other acupuncture-related techniques, such as moxibustion or cupping, were not included.

Objective

The objective of this treatment observation was the assessment of early as well as late results of acupuncture treatment series for lumbago and headache performed on the mixed patient collective of a general practitioner's practice.

Methods

The observation included all patients who received acupuncture for chronic back pain or headache. The treatment observation consists of data collected from 192 treatment series (10 acupuncture sessions each) for lumbago, and 86 treatment series (10 acupuncture sessions each) for headache. There were no restrictions regarding microsystems or acupuncture-related techniques. Acupuncture was administered according to the criteria of Traditional Chinese Medicine; there were no restrictions regarding the selection of the acupuncture points.

Results

The benefit of the treatment in the lumbago group was rated none or poor in 18 cases (9.4 %), moderate in 35 (18.2 %), and very good in 139 (72.4 %) cases. In the headache-group the benefit was rated none or poor in 2 cases (2.3 %), moderate in 28 (32.6 %), and very good in 56 (65.1 %) patients.

Conclusion

The results were encouraging: not only in the restricted setting of a large scientific study, but also within the mixed patient collective of a general practitioner's practice, acupuncture can lead to good results in the therapy of chronic back pain and headache.  相似文献

A patient suffering from sudden anuria, urgency, slight pain over the lumbar region, additional pain in the rectum and in the gluteal area was misdiagnosed with an urological disorder. An MRI performed after 14 days revealed a massive recrudescent lumbar disc herniation (L5/S1) she had experienced for the first time three years before. From the point of view of segmental anatomy the various symptoms may be explained as a reflex pattern of the sclerotome, viscerotome, myotome and dermatome within a specific segmental stratum.  相似文献

Objective

To reach a consensus in the use of acupuncture and related techniques as well as dietetics and Chinese herbal therapy for pediatric illnesses.

Methods

40 specialists in Chinese Medicine in paediatrics were asked to evaluate the effectiveness of the above-mentioned techniques for a given number of indications. Evaluation was classified in a threefold way: useful, less useful or not useful. Further questions referred to specific diagnostic and therapeutic modes as well as to studies in this field.

Results

Seven paediatricians returned the questionnaire. The list of indications was extended to 22, mainly for indications rated as „less useful.” The answers were fairly consistent for paediatric disturbances such as headache, abdominal pain and allergic diseases, and less consistent for only seven out of 22 indications. Most evaluations were based on personal experience, and less on the limited amount of controlled studies in the paediatric field.

Discussion

Differences in evaluation may be due to the different therapeutic focus in the applied techniques. Therapeutic procedures varied the most, when therapy was based on the complementary use of Chinese herbal therapy and Western medicine. A comparison between the techniques applied is hardly possible due to the the different stages of chronicity of the diseases in different clinics.

Conclusions

This study produced a rather homogenous consensus with regard to the effectiveness of acupuncture and related techniques as well as dietetics and traditional Chinese herbal therapy in paediatrics based on expert evaluation (EBM-level IV). Expert opinion is supported by studies (in part EBM-level I and II).  相似文献
