I go to a karate school since last April (now an orange belt, 9th Kyu) that teaches Ryukyu Kempo. In our training manual "Kenpo" is described differntly as Chinese/American with kicks, striking techniques. Kempo also uses kicks and striking, but also teaches weapons (but not very much during the first two belts). The main focus of the art is self-defense. Everything we learn is a defense against a particular attack. The leader of the school (shihan) is trained in pressure points and is also a medical doctor licensed in acupuncture. He and the other instructors teach bunkai (striking combinations) out of kata that incorporate any of the 361 regular pressure points. Ryukyu Kempo is based upon the teachings of George Dillman, who learned it from Taika Oyata. Oyata, who first used the term Ryukyu Kempo as the name for his art, formed the Ryukyu Kempo Association in Okinawa in 1968 (Dillman didn't join him until the 1980's). Dillman Karate International began calling their system Ryukyu Kempo out of respect to Oyata. It is a classical form of MA from Okinawa, and influenced by Chinese knowledge of anatomy and pressure points. The pressure points are used to cause pain, immobilize the opponent, or render the opponent unconscious. We learn that the true value of kata lies in the self-defense techniques contained in them. The school I go to also incorporates Small Circle Jujitsu, Modern Arnis (Filipino stick-fighting), and Tang-Soo-Do. The first kata we learn, for the Orange belt testis Taikyoku Shodan. We learn the nexxt two Taikyoku kata (Nidan & Sandan) for Yellow belt, as well as kata Seisan, which more than a few upper belts wonder why such a difficult kata is learned so early.
