dcterms.abstractAIM: To explore the effectiveness of acupuncture transcutaneous electrical nerve stimulation (Acu-TENS), a non-invasive modality in reduction of rectal discomfort during barostat-induced rectal distension.-
dcterms.abstractMETHODS: Forty healthy subjects were randomized to receive 45 min of either Acu-TENS or placebo-TENS (no electrical output) over acupuncture points Hegu (large-intestine 4), Neiguan (pericardium 6) and Zusanli (stomach 36). A balloon catheter attached to a dual-drive barostat machine was then inserted into the subjects' rectum. A step-wise (4 mmHg) increase in balloon pressure was induced until maximal tolerable or 48 mmHg. Visual analogue scale and a 5-point subjective discomfort scale (no perception, first perception of distension, urge to defecate, discomfort/pain and extreme pain) were used to assess rectal discomfort at each distension pressure. Blood beta-endorphin levels were measured before, immediately after intervention, at 24 mmHg and at maximal tolerable distension pressure.-
dcterms.abstractRESULTS: There was no difference in the demographic data and baseline plasma beta-endorphin levels between the two groups. Perception threshold levels were higher in the Acu-TENS group when compared to the placebo group, but the difference reached statistical significance only at the sensations urge to defecate and pain. The distension pressures recorded at the urge to defecate sensation for the Acu-TENS and placebo-TENS groups were 28.0 +/- 4.5 mmHg and 24.6 +/- 5.7 mmHg, respectively (P = 0.043); and the pressures recorded for the pain sensation for these two groups were 36.0 +/- 4.2 mmHg and 30.5 +/- 4.3 mmHg respectively (P = 0.002). Compared to the placebo group, a higher number of participants in the Acu-TENS group tolerated higher distension pressures (> 40 mmHg) (65% in Acu-TENS vs 25% in placebo, P = 0.02). The plasma beta-endorphin levels of the Acu-TENS group were significantly higher than that of the placebo group at barostat inflation pressure of 24 mmHg (1.31 +/- 0.40 ng/mL vs 1.04 +/- 0.43 ng/mL, P = 0.044) and at maximal inflation pressure (1.46 +/- 0.53 ng/ mL vs 0.95 +/- 0.38 ng/mL, P = 0.003).-
dcterms.abstractCONCLUSION: Acu-TENS reduced rectal discomfort during barostat-induced rectal distension and concurrently associated with a rise in beta-endorphin level.-
