ce companies are unwilling to fork out. The hand is also becoming more advanced with a system discussed in the January 1998 issue of Tech Directions. This system, know as Sabolich's Sense of Feel System, uses a cuff attached to the remaining portion of the limb. Over time a user is able to recognize exactly how much pressure they are using. This system differs form earlier ones in which judgement was based simply on sight, which is not very accurate. By using this system, amputees are able to hold their child’s hand or pick up an egg without the fear of crushing them. Both the Free-Hand system and Sabloich’s sense of feel system are helping amputees feel their way towards a better quality of life. Using these systems, they are moving away from the dreaded metal hook and into the technological world they live in. Although some feeling is addressed in the first point, we must next examine the advancement in sensory receptors which aide to the feelings experienced by amputees. The prosthetic limb has seen great advancement in feel and function but one of the greatest advancements is a system developed by John Sabolich, NovaCare's national prosthetic director. The myo-electric prosthesis with hot and cold sensory receptors described in the April 3, 1998 issue of Philadelphia Business Journal provides one of the unique advancements of the last decade. The system involves temperature sensors, placed in a prosthetic foot or hand that send signals to a computerized advanced circuitry system. Those signals are sent to electrodes on the skin in a person's residual limb. The natural skin receptors send information to the brain, where the sensation is registered. One patient said that he could again feel the warmth of his grandson’s hand and could feel the warmth of his wife’s face. In a recent article titled, “How computers help artificial limbs get smarter” found in the August 14th edition of the Wall St...
