大東流合気柔術
Many of hapkido's joint control techniques are said to be derived largely from Daitō-ryū Aiki-jūjutsu. They are taught similarly to Aikido and Ju Jutsu techniques, but in general the circles are smaller and the techniques are applied in a more linear fashion. Hapkido's joint manipulation techniques attack both large joints (such as the elbow, shoulder, neck, back, knee, and hip) and small joints (such as wrists, fingers, ankles, toes, and jaw).
