As well, the acute sensors and motorized controls enable greater dexterity, even allowing the manipulation and use of small items like keys or credit cards through functioning fingers.In addition to this extreme functionality, the myoelectric artificial limb needs not sacrifice any of its cosmetic appearance.Tags: Literature Review In A DissertationCurriculum Vitae Cover LetterCitations Within An EssaySoldiers Home Ernest Hemingway ThesisDo The Write Thing Essay 2009Thesis Printing Binding London
Since it uses a battery and electronic motors to function, the myoelectric artificial limb does not require any unwieldy straps or harnesses to function.
Instead, it is custom made to fit and attach to the remaining limb (whether above the elbow or below) with maximum suspension using suction technology.
The catch: patients have to undergo a nonessential amputation of the damaged hand to make room for the prosthesis.
Hoping to clarify the choices and considerations, surgeon Laura Hruby and her colleagues at the Medical University of Vienna in Austria published a protocol for selecting the first patients to undergo this intensive procedure and guiding them through it.
The Vienna team focused on people with damage to the brachial plexus, the cluster of nerves that controls muscles in the shoulders, arms and hands.

“Bionic hand reconstruction in patients with brachial plexus lesions, in whom classic primary and secondary reconstructions have failed, gives hope to patients who have lived without hand function for years or even decades,” Hruby says.
As well, though the user experiences direct control and feedback through its mechanical operation, the process can be fatiguing.
Externally-powered artificial limbs are an attempt to solve this physical exertion through using a battery and an electronic system to control movement.
