Since we started to see the advances of technology in the most simple things around the
world, we human beings have wanted to find the way of adapting technology for making our
lives more comfortable and easier, for example all appliances we find in our kitchen,our
computers,cell phones,etc, all these items serve its purpose on making our life easier, we
know preparing the breakfast just takes minutes nowadays.
We have seen Robots becoming a "natural/normal/familiar thing" into our lives, for
example in movies we see them as helpers (just see Bicentennial man- a movie based on a book
written by Isaac Asimov ),and for the medicine field,there have been great advance
with the implantation of chips for helping disabled people to control their sphincters and
body movements,or even for being able to recover sensitivity in our bodies, also we have
witnessed the implantation of robotic arms and legs for many disabled people or war
victims...technology might never have an end which is amazing and fabulous, especially if it
is well used, used especially for helping people who suffer and it's a great hope for many
of us disabled people...
We never know, maybe tomorrow,in a few years more, many of us can walk again,first with a
robot helping us and then maybe we can have some of our damaged body parts replaced by

Robot-Assisted Exercise May Help Disabled Stroke Patients Regain Arm Movement
An experimental robotic device that provides a "power assist" to weakened muscles shows
promising results in improving arm motion in partially paralyzed stroke survivors, according
to preliminary research in the April issue of the American Journal of Physical Medicine &
Rehabilitation. The principal investigator was Dr. Joel Stein of Harvard Medical School and
Chief Medical Officer of Spaulding Rehabilitation Hospital.
After a stroke, many patients are left with severe weakness or paralysis on one side of
the body. Although current rehabilitation programs can improve functioning to some extent,
most individuals with severe arm weakness do not recover satisfactory function. Exercise can
stimulate the injured brain's capacity to repair itself, but individuals with severe
weakness of the affected muscles may have difficulty in performing the needed exercises.
"This pilot study demonstrates the feasibility of using an EMG-controlled powered
exoskeletal orthosis for exercise training in stroke survivors," the researchers write. The
results also suggest that the AJB may one day be used to help to improve upper-limb motor
function in disabled patients with stroke, brain injury, and other nervous system
The researchers envision two possible therapeutic uses for the AJB. As in the pilot
study, it could be used as an aid to exercise training, either to improve muscle control or
to build strength. It might also be used as a powered brace to provide assistance with
everyday tasks in patients with chronic weakness or paralysis, such as that caused by spinal
cord injuries. More study will be needed to address these issues, along with further
development to make the AJB more portable, user-friendly, and comfortable.
About the American Journal of Physical Medicine &
Rehabilitation American Journal of Physical Medicine & Rehabilitation focuses
on the practice, research and educational aspects of physical medicine and rehabilitation.
Monthly issues keep physiatrists up-to-date on the optimal functional restoration of
patients with disabilities, physical treatment of neuromuscular impairments, the development
of new rehabilitative technologies, and the use of electrodiagnostic studies. This
well-established journal is the official scholarly publication of the Association of
Academic Physiatrists (AAP).
