A: From what our clients tell us, our prosthetic devices change their lives in a dramatic way. Essentially they are "life changing" - something so many of our clients say. However function for one person is not always the same for another person. Each person is carefully evaluated to determine their individual needs. Then the prosthesis is engineered to perform these needed functions.
One example of how Dermatos® prosthetic fingers and hands are functional is explained this way: A semi-soft silicone is formed around the remaining portion of the finger/hand, filling the missing area. This formed silicone cradles the residual finger/hand allowing vibration from the tip of the prosthesis to transfer to the nerves at the end of the residual finger/hand. This vibration transfer allows wearers to feel like the prosthesis is an extension of them- rather than a foreign attachment. This feeling is called proprioception.
Proprioception enables partial finger amputees the ability to type on a keyboard, write with pen or pencil, or perform other tasks that were once very difficult, if not impossible.
The primary categories of prosthetic function in hand prosthetics are:
Active Prehension Function: Only a hook, myoelectric or body powered prosthesis will perform successfully. Dermatos® prosthetic devices can be merged with a myoelectric or body-powered prosthesis to also help fulfill the category of psychological and vocational function. Covering a myoelectric or body-powered prosthesis with Dermatos® also aids in prehension by allowing the hand to grasp objects better. This is accomplished through the inherent high friction qualities of the Dermatos® skin.
Proprioception Function: Dermatos® prosthetic devices provide proprioception function for prosthetic fingers and hands by allowing for the transfer of vibration to the residual limb. Since Dermatos® prosthetic devices are custom made to each patient, vibration from the fingers or distal end of the prosthetic devices are successfully transferred to the nerve endings in the wearer's residual limb. This type of function is especially helpful when someone loses part of a finger and needs to type on a computer.
Psychological/Emotional Function: The legitimacy of psychological damage in amputees stemming from their amputation (either traumatic or congenital) has been grossly underestimated. Many amputees avoid public places, hide their residual limb or even avoid employment opportunities due to their disfigurement. A prosthesis which looks extremely life-like, such Dermatos®, is the only type of prosthesis that will fulfill this need. The desire for a very lifelike prosthesis has been unfairly lumped in the same category as unnecessary cosmetic surgery and even cosmetics (make up). The true value of a highly realistic prosthesis is often not recognized until someone becomes a victim of disfigurement themselves. More information on this type of prosthetic function can be found in the company brochure and company philosophy section of our website.
Passive-Active Function: As achieved by hand prostheses can be defined as allowing, or helping a user to perform tasks that do not require active prehension yet are active due to the wearer's movement of their hand/prosthesis. Dermatos® prostheses can provide passive-active function in many different ways. For example: adjusting the fingers of a hand prosthesis to hold a glass or pencil, or use the prosthesis to hold a shopping bag, move a steering wheel, hold groceries, move papers on a desk, hold down an object while using the sound hand, etc. In these cases a hand prostheses that actively grasps is not needed. Another benefit of Dermatos® for this need is its amazing "grabbing" capability (due to its high friction surface.)
Vocational Function: Many people come to Alatheia to get a Dermatos® prosthesis because they need it for their career. For example, many actors cannot get jobs if they have a disfigurement. Many medical doctors also find Dermatos® helpful in providing the necessary ease that their patients lack when they are aware of their prosthesis or disfigurement (visit the arm section to see such a case). The number of careers that Dermatos® prostheses benefit are countless, even fast food workers and bank tellers benefit due to the pubic job they have. However, even if an amputee does not have a job that involves serving the public, since Dermatos® fills the Psychological/Emotional Function it allows wears better career opportunities due to their feeling of security - as well as not being a distraction to others.
Other responses to this question:
Dermatos® prostheses are extremely functional because our patients continue to wear and use them. Many of our patients will not even think about leaving their house without their prosthesis! Our clients have become functional in their jobs and daily lives in ways they could not with a hook or other type of visually obvious prosthesis. The true to life qualities of our prostheses enable our clients to be secure in themselves. Instead be distracted by other peoples' reaction to their prosthesis or amputation their security and peace of mind enables our clients to live happy and productive lives. |
