Objects: To explain the mechanism of PNAP characteristic changes for each Korean Medicine Sasang typology.

Methods: By ways of question form and expert’s deliberation, 1000 healthy volunteers are distinguished into corresponding Sasang types, then detect median, ulnar, peroneal, tibial nerves’ CMAP and F-Wave, to analyze nerve conduction ‘s characteristic changes between groups or within a group.

Results: Within group, TaiYin: Median nerve’s right side MCV is declined than left side; Ulnar and Peroneal and tibial nerve’s left side MCV is declined than right side. ShaoYang: Ulnar and tibial nerve’s left side MCV is declined than right side. (P<0.05). Between groups, TaiYin and ShaoYang: About median and tibial nerve’s Distal Amlitude (DA), MCV, TaiYin is declined than that of ShaoYang; TaiYin and ShaoYin: About tibial nerve’s DA, MCV, The shortest latency of F-wave (FL), TaiYin is declined or extended than that of ShaoYin; ShaoYang and ShaoYin: For median nerve’s MCV, FL, ShaoYin is declined or extended than that of ShaoYang (P<0.05). Nerve amount rate of FL ≥ 2SD (ShaoYang as standard), for peroneal and tibial nerves, TaiYin is greater than ShaoYang and ShaoYin (P<0.01).  Nerve amount rate which conduction is under-activity, for tibial nerve, TaiYin is greater than ShaoYin (right) and ShaoYang (left) (P<0.01). AMP/DUR rate of median nerve: ShaoYin>ShaoYang>TaiYin (P<0.05).

Conclusion: Median nerve’s left side has an advantage than right side, however the ulnar and tibial nerve’s right side is well than left side, this characteristic is much more obvious in TaiYin; PNAP of ShaoYang is well than TaiYin and ShaoYin; AMP/DUR. Rate of median nerve shows sensitively about constitutional differences.

Significance: Provide foundation of clinical diagnosis and treatment on a constitutional basis.
