in this ppt we will se how the bioengineers play major role in the field of rehabilitation.

BIOENGINEERING IN
REHABILITATION

2. Definition
◦ Biomedical engineering, or bioengineering, is the application
of engineering principles to the fields of biology and health
care.
◦ Rehabilitation bioengineering is the application of science
and technology to ameliorate the disabilities of individuals.
◦ Bioengineers work with doctors, therapists and researchers
to increase, maintain and improve functional capabilities of
individuals with disabilities.
◦ They also develop system, equipment and devices in order to
solve clinical problems.

3. Principles used by the
bioengineer
◦ Develop technological solutions and devices to assist
individuals with disabilities.
◦ Aid the recovery of physical and cognitive functions lost
because of disease or injury.
◦ Design and build devices and systems to meet a wide range
of needs that can assist individuals with mobility,
communication, hearing, vision and cognition.

4. ◦ These tools help people with day-to-day activities related to
employment, independent living and education.
◦ To regain functions lost due to disease or injury, such as limb
(arm and or leg) mobility following a stroke or a joint
replacement.

5. Role Of Bioengineer In Rehabilitation
◦ Rehabilitation robotics:-
To use robots as therapy aids instead of solely as
assistive devices. Smart rehabilitation robotics aid mobility
training in individuals suffering from impaired movement, such
as following a stroke.
◦ Virtual rehabilitation:-
which uses virtual reality simulation exercises for
physical and cognitive rehabilitation.

6. ◦ Physical prosthetics:-
Such as smarter artificial legs with powered ankles,
exoskeletons, dextrous upper limbs and hands. This is an
area where researchers continue to make advances in design
and function to better mimic natural limb movement and user
intent.
◦ Advanced kinematics:-
To analyze human motion, muscle
electrophysiology and brain activity to more accurately monitor
human functions and prevent secondary injuries.

7. ◦ Brain computer interfaces:-
These technologies use the brain’s electrical
impulses to allow individuals to move a computer cursor or a
robotic arm that can reach and grab items, or send text
messages.
◦ Sensory prosthetics:-
Such as retinal and cochlear implants to restore
some lost function to provide navigation and communication,
increasing independence and integration into the community.

8. ◦ Secondary disorder treatment:-
Such as pain management.
◦ Neurostimulation:-
In individuals with Spinal Cord Injury (SCI) for
recovery of voluntary control of standing and movement and
involuntary control of blood pressure, bladder etc.
◦ Artificial Hands:-
Capable of Complex Movements and Sensation.

9. Some other major role
◦ Prosthetics, such as dentures and artificial limb
replacements.
◦ Surgical devices and systems, such as robotic and laser
surgery.
◦ Systems to monitor vital signs and blood chemistry.
◦ Implanted devices, such as insulin pumps, pacemakers and
artificial organs.

10. ◦ Imaging methods, such as ultrasound, X-rays, particle beams
and magnetic resonance.
◦ Therapeutic equipment and devices, such as kidney dialysis
and transcutaneous electrical nerve stimulation (TENS).
◦ Radiation therapy using particle beams and X-rays.
◦ Physical therapy devices, such as exercise equipment.

11. Bioengineers and their contributions
◦ Forrest Bird (mechanical ventilator).
◦ John Charnley (artificial hip replacement).
◦ Graeme Clarke (cochlear implant).
◦ Willem Einthoven (electrocardiograph).
◦ Wilson Greatbatch (internal cardiac pacemaker).
◦ Charles Hufnagel (artificial heart valve).
◦ Robert Jarvik (artificial heart).
◦ Willem Johan Kolff (kidney dialysis).
◦ Rene Laënnec (stethoscope).
◦ Michel Mirowski (implantable cardioverter defibrillator).
◦ Wilhelm Roentgen (X-rays).

12. Conclusion
◦ Rehabilitation bioengineering plays a major role in providing
solutions for individuals affected by sensory loss, motor
impairments or communication difficulties.
◦ It also opens new frontiers in our understanding of medical
disorders and their long-term effects and impact on the
quality of life.

13. ◦ Past and current advances in musculoskeletal biomechanics,
robotics, computational modeling, tissue mechanics,
communication, human–machine interfaces and more,
enable patients undergoing rehabilitation to independently
return to their daily life activities.
◦ Rehabilitation bioengineering can be viewed as an interface
for a wide variety of technical, physiological and other
concerns.
