Upper Limb Prosthesis: A Functional Replacement For The Biological Limb?, Ari Schacter
Upper Limb Prosthesis: A Functional Replacement For The Biological Limb?, Ari Schacter
The Science Journal of the Lander College of Arts and Sciences
The 21st century continues to produce major advancements in prosthetic limb technology. Specifically, improvements to the myo-electric prosthesis have helped numerous upper limb amputees, especially transhumeral patients. Targeted muscle reinnervation surgery has allowed for more seamless control of the prosthetic device by creating new control centers for the unused nerves of the residual arm. Additionally, improvements in pattern recognition technology have enabled transhumeral amputees to gain more natural control of the prosthesis and consequently better imitate a biological limb. Another important development is in regards to the configuration and placement of electromyography electrodes on the amputee’s body. Using high-density electrodes …

The global shortage of donor organs is a cause for countless fatalities across the world. Although, diseases can be treated through organ transplantation it can come along with many complications. Not only is there a high demand for donor organs, there is also the risk of the body’s rejection of the newly implanted organ. Through the method of 3D printing organs, many lives could be saved as well as reducing the need for donor organs. Finding materials to create a suitable scaffold is the focus of many experiments. Materials that are used in organ printing are made from soft materials, …

The problem with prosthetics is a longstanding problem that researchers have been working on for many years. They are attempting to create a prosthetic that acts as if it is the original limb or body part. In recent years they have discovered a technology that has assisted many of those who are greatly in need of a prosthetic, such as an amputee or someone who is “locked in”. “Locked in” refers to a person who is technically confined in his own body and has no methods of communication with the world. Brain-computer interface (BCI) has opened up a whole new …

The Science Journal of the Lander College of Arts and Sciences
Organ printing is an emerging technology that can potentially replace the need for human organ transplants altogether. Organ printing uses bioprinting methods to create three-dimensional biological constructs. Although it has not yet been implemented successfully, with nearly two decades of research devoted to this area, much progress has been made. This article outlines the various aspects of the organ printing process, describes both the accomplishments and challenges of bioprinting, and discusses the feasibility of bioprinting as a viable method for organ replacement.

The following is an excerpt from the introduction of this paper: Imagine living a life where even the simplest of tasks such as eating a grape or holding an egg required intense concentration and months of training. Until recently, this was the harsh reality for people with upper limb prostheses. Currently, the most common upper limb prosthetic technology being used is body powered. These devices capture remaining shoulder movements with a harness and transfer this movement through a cable to operate the hand, wrist, or elbow. With this control method, only one joint can be operated at a time. When …
