Animal amputees helping human amputees
Unfortunately, they have to keep being replaced due to professor kettleburn's habit of visiting dragon preserves. In the 100 fic "Twisted steel", after clarke loses her arms in a traumatic accident up on the ark, her father and raven develop a pair of artificial arms for clarke's use. Various flash-forwards show thor continuing to use various prosthetics thousands of years into the future. Former captain america sidekick bucky barnes has a cybernetic left arm to replace the one he lost at the end of world war ii.
Most people are born and raised with all of their body parts functioning perfectly. Our hands can perform complex things, like playing the piano or lifting heavy objects, while our legs enable us to walk, run, and jump. The computer technology in these types of prosthetics has helped thousands of amputees return to daily activities that they never dreamed possible again. Physically challenged patients are now able to return to most all activities – gardening, running, golfing, fishing … whatever they wish to do. This also fairly simple solution comprises a plaster socket with a bamboo or pvc pipe at the bottom, optionally attached to a prosthetic foot. This solution prevents contractures because the knee is moved through its full rom.
The human brain contains multiple hand-selective areas, in both the sensorimotor and visual systems. Could our brain repurpose neural resources, originally developed for supporting hand function, to represent and control artificial limbs? We studied individuals with congenital or acquired hand-loss (hereafter one-handers) using functional mri. We show that the more one-handers use an artificial limb in their everyday life, the stronger visual hand-selective areas in the lateral occipitotemporal cortex respond to prosthesis images. This was found even when one-handers were presented with images of active prostheses that share the functionality of the hand but not necessarily its visual features (e.G. A ‘hook’ prosthesis).
The third type of prosthetic, which is a myoelectric externally powered prosthesis, picks up the electrical action potential in the residual muscles in the amputated limb. Upon receiving the action potentials, the prosthetic amplifies the signal using a rechargeable battery and uses the electric signals to power the motors operating the respective part of the arm. This allows for more freedom and doesn’t require a patient to perform frequent, strenuous muscle contractions.
Ultra-tech features artificial replacements or improvements for everything. One issue of pyramid, zauberpunk listed all sorts of crazy magical replacement arms including one with no physical substance. The "Fudge 10th anniversary edition" book for fudge contains rules for all sorts of implants, and by default there is no reason other than money not to have them. That said it also notes that just having arms and legs won't let you have super-strength because the human body can't support it, right before presenting a body frame that does let you do this. Having steam- or cyber-ware installed still lowers a character's spirit attribute. Though that's probably justified in this case given that the limbs run on ghost rock, a fuel source made of damned souls.
You only live twice - dikko henderson, bond's contact in tokyo, has an artificial leg from a war injury. Has a guy setting off a metal detector, and removing first one of his hands, then one of his legs. Izuku has long since lost his arm to the moon prescence in the bloodstained hero. His replacement, isshin, is made of porcelain, siderite, and hunter's bones. After losing all four limbs to a serial killer with a heated cleaver, nanami shirotaka of halkegenia online zero hour designed a set of robotic prosthetics.
Looking to the future, bensmaia is hopeful that more sophisticated prosthetic devices are on the way, especially with greater private sector involvement, as seen with elon musk’s brain-computer interface firm neuralink and deka’s impressive luke arm. The progress on sensory feedback is encouraging but limited, and there are a host of questions for bensmaia and other researchers to answer before the true technological revolution can begin. In terms of the nerve, bensmaia says the challenge is a purely technological bottleneck. System uses tiny magnetic beads to rapidly measure the position of muscles and relay that information to a bionic prosthesis. In 80 percent of the cases due to dysvascular problems (poor circulation caused by various diseases such as diabetes, cardiovascular disease, etc.), the individual would wind up losing their other leg within five years of the first amputation.
