What Is The Future Of Prosthetics?
The emergence of inventive new materials, engineering
breakthroughs, and advances in microtechnology has served as the
catalyst for innovation in modern prosthetics development. As a
result of these advances, modern prostheses are more
lightweight, more responsive, and more comfortable than models
developed even just a few years ago. Wearers of prostheses have
more options than ever before, allowing amputees to participate
in life activities never before thought possible.
A number of new technologies are just beginning to become a
reality for prosthetic wearers. Neuroelectronics is one of the
industry's newest fields. Scientists studying cognitive control
signals report that "eavesdropping" on neurons in the brain
allow them to predict how the body will respond. The signals can
be directed to a prosthetic brain, or electrical processing
center, which interprets the signals and moves the prosthetic
limb. For example, consider the individual who goes to reach for
a book. As he decides to reach, he sends an invisible electrical
signal to the brain that tells the body it needs to prepare to
move. The brain receives the signal and decodes it, sending a
signal to the right arm to extend and move towards the book.
Scientists propose using these same mechanics to develop smart
prosthetic devices. This entails tapping into neural signal
pathways and using them to direct prosthetic limbs just as the
brain directs natural limbs.
Sensor sockets are another new innovation in the field of
prosthetic development. Sensor sockets are monitoring devices
designed to serve as an interface between the limb and the
prosthesis. The socket is comprised of a net of sensors that can
detect information from the limb and transmit it directly to a
medical facility for evaluation. The hope is that the
information received from the socket sensor will allow
rehabilitation doctors to evaluate the individual's condition
and the performance of the limb. With time, doctors hope that
the use of sensor sockets will be used as a means to maximize
the effectiveness and comfort of the limb. The sensors could
potentially allow for real-time adjustments in the performance
of the prosthetic, thereby improving a patient's quality of life
and enhancing patient treatment.
In addition to these two exciting new emerging technologies,
progress continues to be made in the comfort and construction of
current prosthetic devices. Incremental improvements in the
flexibility, cushioning, and rotational ability of modern
artificial limbs increase a prosthetic's comfort and
functionality, allowing prosthetic wearers to come closer to
feeling like they are wearing a natural limb. And as the quality
of prosthetics increases, prosthetic wearers are more able to
resume activities previously made difficult by their lack of a
natural limb.
