12. Gall Bladder Meridian Point 31 (GB-13)

On the lateral aspect of the thigh, it is located 7″ above the transverse popliteal crease. The point is located between the two sinews on the outer side above the knee. An easy way to determine the point is at the end of the middle finger when the hand is placed on the thigh in a standing position.

Most schoolboys have experienced this dead leg (temporary paralysis) from a knee strike, but a punch or kick can also cause it. In Western medicine the strike is impacting the lateral femoral cutaneous nerve, which is a muscular branch of the femoral nerve.

13. Liver Meridian Point 9 (LIV-9. or LV-9)

Four inches above the medial epicondyle of the femur, between the vastus medialis muscle and the sartorius muscle.

In Dim Mak, this is defined as a knockout point. I have seen it indicated in many textbook karate applications where a kick to the inner thigh is used, but usually to collapse the leg at the knee.

14. Bladder Meridian Point 56 (BL 56)

It is located in the centre of the gastrocnemius muscle in the leg’s calf.

The results of a strike are instant cramping of the muscle, which, depending on the condition of the muscle, can include damage ranging from minor to massive tearing of the tissue and possible separation of the muscles from the Achilles tendon. A hard strike or kick compresses the muscle against the tibia, causing a severe muscle cramp that slows movement significantly. It is used heavily in Muay Thai.

15. Spleen Meridian Point 6 (SP6)

Three inches directly above the tip of the medial malleolus, on the posterior border of the tibia.

In the protuberance beneath the bone, three inches above the tip of the ankle. As shown in the illustration, you can use your hand as a guide marker.

In Dim Mak, this area is known as the ‘3 Yin Crossing’, where the kidney and liver meridians cross with the spleen meridian at the SP-6 point, supposedly giving enhanced effects. In Western medicine, this point lies on the posterior tibial nerve.

According to many sources, this area is one of the best points to hit with a fast low kick for self-protection. It is claimed to inflict severe pain and nausea.

This point needs to be a bit more accurate than the others mentioned above.
