Continuing with our introduction into techniques and the applied anatomy at work…
Nikyo is the second teaching of Aikido (ni-two, kyo-teaching). It is a joint-lock technique that results in extreme pain. Nikyo allows one to control an opponent by effectively destroying his will to continue fighting.
Nikyo is accomplished by flexing and adducting an opponent’s wrist producing an instantaneous sharp pain that causes him to fall to his knees involuntarily to alleviate the pressure. The exact etiology of the pain elicited by this technique has been obscure to many practitioners. Explanation of the anatomy and mechanics of Nikyo have been published in medical literature. What is clear, from actual studies of cadavers (yes, that’s dead people), is that Nikyo forcibly compresses the pisiform bone against the ulna (two bones that do not normally articulate) overstimulating the periosteal nerves.
Why cadavers? Because it really hurts! That and it’s probably unethical to repeatedly subject one to Nikyo for science. On the mat however, you will practice Nikyo at least one thousand times.
Sankyo is the third technique in Aikido (san –three, kyo –teaching). It is a common wristlock (easily recognized by anyone who has practiced judo or ju jiustu) which involves forced supination or pronation of the wrist. Sankyo is typically applied by holding and twisting the hand. For added suggestion, one can grab the small or pinky finger with the lower hand.
Sankyo is effective for the reason that the wrist joint does not mechanically allow for a full degree of circular rotation -things like bones and tendons tend to get in the way. Accordingly, force is transferred to the forearm causing radioulnar rotation, eventually resulting in a joint lock on the radioulnar joint. Once the radius and ulna have been brought to their extreme positions, further twisting motion will put severe torque on the wrist.
Sankyo is often accompanied by an opponent instinctively throwing him or herself to escape or alleviate the surprisingly painful lock. Sankyo is typically applied for control and should not cause long-term damage. As in the case of Shihonage, the advanced Aikidoka will refine Sankyo to generating torque through your hips and not your arms.
