초록
The loss of an upper limb significantly limits the functional activities of daily living. A huge emphasis is placed on the manipulation, shape, weight, and comfort of a prosthesis, to enable its use as an inherent body part. Even with technological advances, customized upper-extremity myoelectric prosthesis remain heavy and expensive. The high cost of upper-extremity prosthesis is an especially steep economic barrier for patients. Three-dimensional (3D) printing is a promising avenue for reducing the cost of prosthesis. We applied 3D-printed pressure-sensored prosthetics to a traumatic transradial amputee, and compared the hand functions with a customized myoelectric prosthesis. The 3D-printed pressure-sensored prosthetics showed low grip strength and decreased dexterity compared to the conventional myoelectric prosthesis. Although there were a few limitations, the fabrication of prosthesis with 3D printing technology can overcome previous problems such as high production cost, long fabrication period and heavy weight.
