1. An apparatus for assisting a finger motion, the apparatus comprising:
a palm support installable to surround a part of a hand-back and a wrist;
an extension assist unit securable at a first side thereof to a middle phalanx region of a finger and connected at a second side thereof to the palm support to assist extension of the finger through an elastic force between both ends; and
a flexion assist unit comprising a distal phalange support mountable on an end of the finger, and a first flexion wire and a second flexion wire mountable on a part of the finger and assisting flexion of the finger on the basis of a tensile force provided to the flexion wires;
wherein the extension assist unit further comprises a first extension elastic member connected at a first end thereof to an outside part of the distal phalange support and connected at a second end thereof to a part of the palm support coming into contact with the hand-back; and
wherein the second flexion wire is formed such that a first end thereof is secured to a part of the first extension elastic member passing through an outside of the middle phalanx region of the finger, and a second end thereof is configured to surround a circumference of the proximal phalange region of the finger obliquely inwards and then passes through a part of the palm support coming into contact with the palm.
