Prosthetics

Effectiveness

Artificial legs are usually more effective than artificial arms or hands in duplicating the motions of the natural limb. The broad and straight movements of the legs are easier to duplicate than the more intricate and quicker actions of the arms and hands. To compensate for these difficulties, artificial hands and arms with advanced designs that include electronic circuitry allow for a wider range of motion and use. Nerve impulses reaching the stump are transformed to appropriate movements of the prosthesis. Individuals using specialized hand and arm prostheses may have several different ones for different occasions. One could be a glove for social use while another for work might be shaped like a claw or have several different power attachments.
