Difference in Clinical Effect between Deep and Superficial Acupuncture Needle Insertion for Neck-shoulder Pain: a Randomized Controlled Clinical Trial Pilot Study / 日本温泉気候物理医学会雑誌

Objective: The purpose of this study was to compare the effects of superficial and deep insertion of acupuncture needles in the treatment of patients with neck-shoulder pain and to search for more effective acupuncture methods. Methods: The subjects were patients seen at the Meiji University of Integrative Medicine’s Department of Orthopedic Surgery Clinic. A randomized controlled clinical trial was conducted in which 20 patients with neck-shoulder pain were randomly allocated to either a superficial acupuncture group (n=10) or a deep acupuncture group (n=10). Treatment was applied to points where patients experienced the most pain. The maximum number of stimulation points for both groups was 10. In the superficial acupuncture group, the needle was only inserted to a depth of 5 millimeter. In the deep acupuncture group, the needle was inserted to a depth of 15 to 20 millimeter. Both groups were manually stimulated using a sparrow pecking method over 20 seconds, after which the needle was removed. Both groups were treated weekly for four weeks. The primary outcome measurement was intensity of pain evaluated using a Visual Analogue Scale (VAS). The secondary outcome measurement was the Neck Disability Index (NDI) for the purpose of evaluating the grade of disability in daily life due to neck-shoulder pain. Results: There were no significant differences in age, male-female ratio, disease duration, or the initial scores of VAS and NDI between the two groups. VAS and NDI scores indicated significant differences between the groups (VAS: <0.0001, NDI: p<0.0001) in change over time, with the deep acupuncture group having more favorable results than the superficial acupuncture group. The degree of change from the baseline at the time of each evaluation was calculated, and results for the two groups were compared. The deep acupuncture group showed significantly better improvement in the sustained effects after completion of treatment (VAS: p<0.05). There were no significant differences directly after the first treatment (VAS: p=0.72) or in cumulative effect after repeated treatment (VAS: p=0.24). Discussion and Conclusion: The results of this study suggested it would be more efficient to insert the needle to deep tissues when performing acupuncture treatment on subjective pain sites. The difference in the effects between the two acupuncture methods may be due to the difference in tissue stimulation received. The difference in effect is thought to be due to the differing influence of treatment on pain threshold, muscle blood flow, and muscle tones.

Difference between therapeutic effects of deep and superficial acupuncture needle insertion for low back pain: A randomized controlled clinical trial / 全日本鍼灸学会雑誌

[Objective]The purpose of this study was to compare the effects of superficial and deep insertion of acupuncture needles in the treatment of patients with low back pain and to search for more effective acupuncture methods.<BR>[Methods]A randomized controlled clinical trial was conducted in which 32 patients with low back pain for more than three months of duration were randomly allocated either to a superficial acupuncture group (n = 16) or a deep acupuncture group (n = 16). Treatment was done for the most painful points of the patients. In the superficial insertion group, the needle was only inserted to a depth of 5 mm, whereas in the deep insertion group, the needle was inserted to a depth of about 20 mm, and was manually stimulated (sparrow pecking method) for 20 seconds. Both groups were treated weekly for four weeks. The visual analog scale (VAS) of pain, Roland-Morris Disability Questionnaire (RDQ), and Pain Disability Assessment Scale (PDAS) were used for outcome measurement. <BR>[Result]VAS, RDQ and PDAS scores showed significant differences between groups (VAS:p < 0.05, RDQ:p <0.001, PDAS:p < 0.05) in change over time with the deep insertion group having more favorable results than the superficial insertion group. The degree of change from the baseline at the time of each evaluation was calculated and results for the two groups were compared. The deep insertion group was significantly better in tendency to improve directly after the first treatment (p < 0.01), in cumulative effect after repeated treatment (VAS:p = 0.13, RDQ:p < 0.05, PDAS:p < 0.01), and in sustained effect after completion of treatment (VAS:p < 0.05, RDQ:p < 0.01, PDAS:p <0.05).<BR>[Discussion and Conclusion]The study showed that deep stimulation is a more effective treatment than superficial stimulation. It is thought that the differences of the effects are due to different influences of the treatments on the pain threshold, muscle blood flow, and muscle tones.

Predicting the Depth of Insertion of Left-sided Double-Lumen Endotrachial Tubes in Koreans

BACKGROUND: Proper positioning of a double-lumen endobronchial tube is very important for lung isolation. This is best achieved by using a fiberoptic bronchoscope. Yet it is also important to predict the proper length when performing bronchoscopy is not possibe. In a previous report, the ideal depth of insertion of the left-sided double lumen endobronchial tube (DLT) was significantly correlated with the patient's height and the clavicular-to-carinal distance of the trachea. The aim of our study is to see whether that result can be applied to Koreans or not. METHODS: Forty eight patients who undergoing one lung ventilation (OLV) were intubated with a left-sided DLT. After proper positioning was achieved by bronchoscopy, we measured the depth of the tube at the upper incisor. Multiple linear regression analysis was done to determine the correlation of the depth of insertion with other factors. RESULTS: In Koreans, the depth of insertion was 9.216 + 0.104 x height + 1.797 x gender (male = 1, female = 0, R = 0.912, P = 0.003). CONCLUSIONS: In Koreans, the depth of insertion was only correlated with the gender and height of the patient, but not with the clavicle-to-carinal distance.
