Objective:To observe the channel state in patients with acute sport injury of external malleolus joint from the cutaneous electrical conductance quantity(ECQ)of Jing(Well)-points

Yuan(Source)-points and Luo(Collateral)-points of the twelve regular channels.Methods:Forty-five patients with acute sport injury of external malleolus joint were chosen to be used as the observation group

and 30 healthy people as the control group.The ECQ of the cutaneous tissue of Jing-points

Yuan-points and Luo-points of the twelve regular channels was detected by using HB-DET Acupoint Diagnosis-Therapeutic Apparatus under room temperature.If the difference of ECQ values between the bilateral limbs exceeded 50%

it was considered to be imbalance.Results:In observation group

the imbalance state reflected from ECQ of Jing-points mainly involved Trienergizer Channel of Hand-Shaoyang and the Kidney Channel of Foot-Shaoyin

with the imbalance rate being 60.0%(27/45)and 55.6%(25/45)respectively which were significantly higher than those [0 and 3.3%(1/30)] of control group(P<0.05).The ECQ of the Yuan-points of the 12 regular channels indicated that the imbalance state mainly involved the Bladder Channel(32/45

71.1%)

Gallbladder Channel(30/45

66.7%)

Liver Channel(28/45

62.2%)

Kidney Channel(27/45

60.0%)

Stomach Channel(25/45

55.6%)and Pericardium Channel(21/45

46.7%)which were significantly higher than those [1/30(3.3%)

and 0] of control group in the number of imbalanced channels(P<0.05).The ECQ of the 12 Luo-points showed that the imbalanced channels were mainly Gallbladder Channel(29/45

64.4%)and Bladder Channel(29/45

64.4%)which were significantly higher than those [0

and 1/30(3.3%)] of control group in the number(P<0.05).Of the 540 Jing-points

540 Yuan-points and 540 Luo-points

93(17.2%)

181(33.5%)and 96(17.8%)appeared imbalance

and the imbalance rate of Yuan-points was apparently higher than those of Jing-points and Luo-points(P<0.05).Conclusion:Acute sport injury of external malleolus joint may lead to imbalance of channels passing through the injured areas

and also involves the channel(Pericardium Channel)dominated by the heart and the 12 Yuan-points.
