In western medicine, the diaphragm is the main inspiratory muscle. It is involved in the postural control of the trunk and contributes to balance performance. In traditional Chinese medicine (TCM), the diaphragm represents a gateway between the lower and upper parts of the body, and it regulates the descending and ascending functions of the whole organism. The aim of this study was to assess the effect of acupuncture on diaphragm function.
A proof-of-concept, prospective, controlled, pilot trial in healthy volunteers. Respiratory rate, inspired volume, diaphragm excursion, and thickening were measured during tidal and maximal breathing at baseline and after sham or real acupuncture. Acupuncture was performed on Yanglingquan (GB34), Tai Chong (LV3), Danzhong (CV17), Geshu (BL17), and Geguan (BL46).
Ten participants were enrolled (6 males, weight 71 ± 12 kg, height 173 ± 9 cm, BMI 21 ± 1.3 kg/m). During tidal breathing, tidal volume, diaphragm displacement, and end-expiratory diaphragm thickness did not change with sham or real acupuncture as compared to baseline; thickening ratio was 43.5 ± 16.6 vs. 31.3 ± 14.9 (sham) vs. 30.8 ± 15.3% (baseline), =0.1066. During breaths at vital capacity, the acupuncture group, as compared to both baseline and sham acupuncture, had a trend toward a larger tidal volume (3840 ± 690 vs. 3110 ± 880 vs. 3230 ± 750 ml, =0.1247) and showed a significantly higher thickening ratio (270.6 ± 136.4 vs. 172.4 ± 57.4 vs. 188.6 ± 41.7%, =0.0414).
Acupuncture significantly influenced diaphragm function in healthy volunteers, improving its inspiratory thickening fraction during breaths at vital capacity, as compared to no or sham acupuncture.
在西医中，膈肌是主要的吸气肌。它参与躯干的姿势控制并有助于平衡能力。在中医里，膈肌代表着身体上下部分之间的通道，调节着整个机体的升降功能。本研究的目的是评估针刺对膈肌功能的影响。
在健康志愿者中进行一项概念验证性、前瞻性、对照性的试验。在基线以及假针刺或真针刺后，于潮气呼吸和最大呼吸时测量呼吸频率、吸气量、膈肌移动度和增厚情况。针刺穴位为阳陵泉（GB34）、太冲（LV3）、膻中（CV17）、膈俞（BL17）和膈关（BL46）。
招募了10名参与者（6名男性，体重71±12千克，身高173±9厘米，BMI 21±1.3千克/平方米）。在潮气呼吸时，与基线相比，假针刺或真针刺后潮气量、膈肌位移和呼气末膈肌厚度均未改变；增厚率分别为43.5±16.6%、31.3±14.9%（假针刺）和30.8±15.3%（基线），P=0.1066。在肺活量呼吸时，与基线和假针刺组相比，针刺组潮气量有增大趋势（3840±690毫升、3110±880毫升和3230±750毫升，P=0.1247），且增厚率显著更高（270.6±136.4%、172.4±57.4%和188.6±41.7%，P=0.0414）。
与未针刺或假针刺相比，针刺显著影响健康志愿者的膈肌功能，在肺活量呼吸时改善了其吸气增厚分数。
