Forty normal subjects were assessed for local skin sensory changes of the knees after acupuncture needle insertion. Correct insertion sites were used on one knee and incorrect sites on the other knee. No significant change of sensation was found over the L3 and L5 dermatomes when incorrect sites were used. Pain sensation was markedly diminished on the side where correct sites were used; minimal transient diminished sensation of heat and vibration was noted.
对40名正常受试者进行了针刺入膝盖后局部皮肤感觉变化的评估。在一侧膝盖使用正确的针刺部位，另一侧膝盖使用错误的部位。当使用错误部位时，在L3和L5皮节上未发现感觉有明显变化。在使用正确部位的一侧，疼痛感觉明显减轻；观察到热觉和振动觉有轻微的短暂减退。
