The cycloid curve has been long considered a special curve, both for its fascinating properties such as that promoted scientific disputes mainly along the seventeenth century. So much so that it is known in the literature as the Helena Helena geometry or curves. The nickname was bestowed in honor probably Helen of Troy, on well with the beauty of it, either with the disputes it caused in life. According to Greek mythology, Helen of Troy (wife of Menelaus, king of Sparta) was kidnapped by Paris (younger son of Priam, king of Troy), thus giving rise to the famous Trojan war, told in Homer's Iliad. A cycloid is the locus (or curve) generated by a fixed point of a circle that rolls evenly and without slipping on a straight line. Galileo became interested in the properties of the cycloid curve from the year 1599. By 1640, Galileo himself was interested in getting the relationship between the area enclosed by the cycloid with its string and the area enclosed by the circle which generates the curve. When inflamed, the tendons of the wrists and hands can lose their ability to slip clutches into the membrane that covers it. It is then necessary to stretch and slide the tendons to improve mobility within the membrane with the intention to reduce the possibility of scarring and enhance their ability to contract properly. 1) Technique: With the wrist in neutral position (not bent), hold blocked the movement of the first and second knuckle of each finger. Try to bend the top of the finger. Do this 10 times with each finger. Then hold each finger on the first knuckle and try to bend the rest of the finger. Do this 10 times with each finger. Then, using a hook grip position, the wrist is neutral, flexed fingers at the knuckle up and means (such as imitating a claw). Keep 10 to 15 seconds. Finally, the full fist. The wrist neutral, the first and second knuckle bent, stretched above the knuckle. Keep 10 a15segundos. 3) Technique: With the wrist extended, hold three of the four fingers extended with the other hand, leaving a free finger. Free finger flex toward the palm. Go slowly 10 times with each finger. .
