L1 MAIN ASPECTS TO RE :L1 MAIN ASPECTS TO RE By Dr.Eng WALID TARAWNEH Rehabilitation Engineering


Rehabilitation Engineering :Rehabilitation Engineering Definition : Rehabilitation : is the (re)integration of an individual with a disability into society Rehabilitation Engineering : A total approach to rehabilitation that combines medicine, engineering, and related sciences to improve the quality of life of persons with disabilities. James Reswick (1982), a pioneer in this field : Rehabilitation engineering is the application of science and technology to improve the handicaps of individuals with disabilities. RENSA (Rehabilitation Engineering and Assistive Technology Society of North America) The application of science and technology to improving the quality of life of people with disabilities. 13/2/2009 8 Dr.Eng. Walid Tarawneh


RE -Concepts :RE -Concepts WHY RE ? We need for People with Disability to live healthier, more productive, and longer lives. RE--? Functionality--?Quantification Stroke Spinal cord injury Burns Cognitive impairments ????? ???????? Rehabilitation engineering requires a multidisciplinary effort Rehabilitation Engineers ( RE,s) generally work in a team setting, in collaboration with physical and occupational therapists, orthopedic surgeons, physical medicine specialists and/or neurologists. 13/2/2009 9 Dr.Eng. Walid Tarawneh


Slide 10:RE,s work with: Clients and their families, teachers, employers Health care providers Region of interest of RE : Activities of daily living (ADL) : (eating, toileting, combing hair, brushing teeth, reading, etc) Mobility and the limitations to mobility : personal Mobility (within a home or office) or public (automobile, public transportation, accessibility questions in buildings). Mobility also includes the ability to move functionally through the environment The question of mobility is not limited to that of getting from place to place, but also includes such questions as whether one can reach an object in a particular setting or whether a paralyzed urinary bladder can be made functional again Barriers that limit mobility are also studied sensory disabilities (sight or hearing, or with communications disorders) 13/2/2009 10 Dr.Eng. Walid Tarawneh


Slide 11:Development of RE technological products : required the contributions of mechanical, material, and engineers, orthopedic surgeons, prosthetists and orthotists, allied health professionals, and computer professionals Example, the use of voice in many assistive devices, as both inputs and outputs, depends on digital signal processing chips, memory chips, and sophisticated software developed by electrical and computer engineers 13/2/2009 11 Dr.Eng. Walid Tarawneh


Technological Fields of RE :Technological Fields of RE Rehabilitation /Assistive Technology Prosthetics and Orthotics, Artificial Organs sensory substitution ??????? systems Electrophysiology Human Biomechanics Ergonomic (human factors) Rehabilitation robotics Mobile / transportation modulates Physiotherapy devices ( electro , thermo ,light ,wave, inhalation ….etc ) 13/2/2009 12 Dr.Eng. Walid Tarawneh


Assistive Technology AT :Assistive Technology AT It is a product of rehabilitation engineering activities. AT Definition: ACCORDING TO RESNA- ( REHABILITATION ENGINEERING AND ASSISTIVE TECHNOLOGY SOCIETY OF NORTH AMERICA ) “It is products, devices or equipment … that are used to maintain, increase or improve the functional capabilities of individuals with disabilities” (1998 Tech Act) Devices for AT can range from low-technology devices that are inexpensive and simple to make to high-technology devices that are complex and expensive to fabricate. Examples of low-tech devices: include dual-handled tools and mouth sticks for reaching. Examples of High-tech : include computer-based communication devices, reading machines with artificial intelligence, and externally powered artificial arms 13/2/2009 13 Dr.Eng. Walid Tarawneh


Prosthetics / Orthotics :Prosthetics / Orthotics Orthotics : are appliances that aids an existing function. Example : An ankle brace????? ?????? is an orthosis, So are eyeglasses. Prosthetics : are devices that replace a body part both structurally and functionally. Example: artificial limb is a prosthesis , So are wheel chair orthoses Prosthesis 13/2/2009 14 Dr.Eng. Walid Tarawneh

Ergonomic (human factor) :Ergonomic (human factor) Definition : Applying information about human behavior, abilities, limitations, and other characteristics to the design of tools, adaptations, electronic devices, tasks, and interfaces is especially important when designing assistive technology because persons with disabilities generally will be less able to accommodate poorly designed or ill-fitted assistive devices 13/2/2009 19 Dr.Eng. Walid Tarawneh

Walid Tarawneh


Rehabilitation Engineers as Clinician :Rehabilitation Engineers as Clinician RE,s have more clinical work than other engineering fields RE,s serve in clinical roles where ever PWD use technology : Assess safety and efficacy of technology for patient Design unique devices or work with manufacturers on custom devices Design environmental modification make modifications to commercial products Specify , assemble and train clinicians / consumers in the use of complex technologies Assist in explanation / translation the impact of use and environment on assistive technology Record and document results of technology uses RE,s must learn how to work with people with disabilities 13/2/2009 24 Dr.Eng. Walid Tarawneh


Rehabilitation Engineers as Translator :Rehabilitation Engineers as Translator Consumers with disabilities often require consultation from several professionals RE,s use their knowledge of engineering to describe the limits of the technology and the impact of the pattern of use and the environment RE,s test and verifies safety and effective operation of devices and systems RE,s convert clients / therapist description into specifications RE,s track the maintenance and repair of devices 13/2/2009 25 Dr.Eng.
