Comparison between transcutaneous nerve stimulation analgesic effect and electroacupuncture analgesic effect in rabbits.

Zhou GZ, Xi GF.

To compare Transcutaneous Nerve Stimulation Analgesia (TNSA) with Electroacupuncture Analgesia (AA), we observed their effect and mechanism parallelly. The results are as follows: 1. Both TNSA and AA can produce significant current-dependent analgesia. The latency of AA is shorter than that of TNSA. 2. Under the present condition (lower-frequency, lower-intensity) naloxone can antagonize partly AA but not TNSA. 3. TNSA effect could be blocked partly by deep or intradermal injection of procaine into points. However, AA effect could be almost blocked completely by deep injection and not by intradermal injection of procaine.
