Acupuncture has been used as a therapy for various gastrointestinal disorders, including irritable bowel syndrome (IBS). However, there is scant information on the effect of acupuncture on gut physiology. The purpose of this study was to evaluate the effect of transcutaneous electrical acustimulation (TEAS) on rectal tone, compliance and perception in IBS patients.
Seven patients with diarrhea-predominant IBS were studied during control, sham stimulation and acupoints (ST36 and P6) stimulation periods. Rectal tone, compliance and perception to rectal balloon distension were assessed with a barostat apparatus.
Acustimulation at ST36 and P6, but not sham stimulation, significantly increased the threshold of rectal sensation of gas, desire to defecate and pain, as compared to control period. However, rectal tone and compliance were not significantly affected during TEAS.
TEAS, at the above acupoints, can reduce rectal sensitivity in IBS patients. The effect is not modulated by changes in rectal biomechanics.
针灸已被用作治疗包括肠易激综合征（IBS）在内的各种胃肠道疾病的一种疗法。然而，关于针灸对肠道生理功能影响的信息却很少。本研究的目的是评估经皮电刺激穴位（TEAS）对IBS患者直肠张力、顺应性和感觉的影响。
对7例腹泻型IBS患者在对照期、假刺激期和穴位（足三里（ST36）和内关（P6））刺激期进行研究。使用压力传感器装置评估直肠张力、顺应性以及对直肠气囊扩张的感觉。
与对照期相比，针刺足三里（ST36）和内关（P6），而非假刺激，显著提高了直肠对气体、便意和疼痛感觉的阈值。然而，在TEAS期间，直肠张力和顺应性并未受到显著影响。
在上述穴位进行TEAS可降低IBS患者的直肠敏感性。这种效果不受直肠生物力学变化的调节。
