The field of rehabilitation robotics develops roboticsystems that assist persons who
have a disabilitywith necessary activities, or that provide therapyfor persons seeking
to improve physical or cognitivefunction. This chapter will discuss both ofthese
domains and provide descriptions of the majorachievements of the field over its short
history.Specifically, after providing background informationon world demographics
(Sect. 53.1.2) and thehistory (Sect. 53.1.3) of the field, Sect.53.2 describesphysical
therapy and training robots, andSect. 53.3 describes robotic aids for people
withdisabilities. Section 53.4 then briefly discusses recentadvances in smart
prostheses and orthosesthat are related to rehabilitation robotics. Finally,Sect. 53.5
provides an overview of recent work indiagnosis and monitoring for rehabilitation as
wellas other health-care issues. At the conclusion ofthis chapter, the reader will be
familiar with thehistory of rehabilitation robotics and its primaryaccomplishments,
and will understand the challengesthe field faces in the future as it seeks toimprove
health care and the well-being of personswith disabilities. In this chapter, we will
describean application of robotics that may in the futuretouch many of us in an
acutely personal way.
When we become unable to interact physically withour immediate environment as we
desire in order toachieve our personal goals through injury or disease, orwhen one of
our family members, friends or neighborsis in this situation, we seek
technology-based solutionsto assist us in relearning how to complete our activi-ties of
daily living (ADLs), or to assist us in actuallydoing them if we are unable to relearn.
While humantherapists and attendants can indeed provide thetypes of assistance
required, the projected short-termdemographics of China, Japan, and the
Scandinaviancountries show a growing shortage of working-ageadults. Age-related
63
disabilities will soon dominate theservice sector job market, put many older and
disabledpeople at risk, and increase the need for institutionalizationwhen there is no
viable home-based solution.National programs to develop personal robots,
robotictherapy, smart prostheses, smart beds, smart homes,and tele-rehabilitation
services have accelerated in thepast ten years and will need to continue apace with
theever-increasing ability of health care to allow people tolive longer through the
repression of disease and improvementsin surgical and medication
interventions.Rehabilitation robotics, although only a 40-year-old discipline[53.1–3],
is projected to grow quickly in thecoming decades.
The field of rehabilitation robotics is generally dividedinto the categories of therapy
and assistance robots. Inaddition, rehabilitation robotics includes aspects of
artificiallimb (prosthetics) development, functional neuralstimulation, (FNS) and
technology for the diagnosis andmonitoring of people during ADLs.Therapy robots
generally have at least two mainusers simultaneously, the person with a disability
whois receiving the therapy and the therapist who sets upand monitors the interaction
with the robot. Types oftherapy that have benefited from robotic assistance areupper-
and lower-extremity movement therapy, enablingcommunication for children with
autism, and enablingexploration (education) for children with cerebral palsyCP) or
other developmental disabilities.A robot may bea good alternative to a physical or
occupational therapistfor the actual hands-on intervention for several reasons:(1) once
properly set up, an automated exercise machinecan consistently apply therapy over
long periods of timewithout tiring; (2) the robot’s sensors can measure thework
performed by the patient and quantify, to an extentperhaps not yet measurable by
clinical scales, any recoveryof function that may have occurred, which maybe highly
motivating for a person to continue with thetherapy; and (3) the robot may be able to
engage thepatient in types of therapy exercises that a therapist cannotdo, such as
magnifying movement errors to provokeadaptation [53.4, 5].
Assistive robots are generally grouped accordingto whether they focus on
64
manipulation, mobility,or cognition. Manipulation aids are further classifiedinto
fixed-platform, portable-platform, and mobileautonomous types. Fixed-platform
robots perform functionsin the kitchen, on the desktop, or by the bed.Portable types
are manipulator arms attached to an electricwheelchair to hold and move objects and
to interact with other devices and equipment, as in opening a door.Mobile autonomous
robots can be controlled by voice or other means to carry out manipulation and other
errands in the home or workplace. Mobility aids are divided into electric
wheelchairs with navigation systems and mobile robots that act as smart, motorized
walkers, allowing people with mobility impairments to lean on them to prevent falls
and provide stability. The thirdmain type, cognitive aids, assist people who have
dementia autism or other disorders that affect communication and physical
well-being.The fields of prosthetics and FNS are closely alliedwith rehabilitation
robotics. Prostheses are artificial hands, arms, legs, and feet that are worn by the user
to replace amputated limbs. Prostheses are increasingly incorporating robotic features.
FNS systems seek to reanimate the limb movements of weak or paralyzed people by
electrically stimulating nerve and muscle. FNS control systems are analogous to
robotic control ystems, except that the actuators being controlled are human muscles.
Another related field is technology for monitoring and diagnosing health care issues
as a person performs ADLs. The chapter is organized according to this taxonomy.
After providing background information on world demographics (Sect. 53.1.2) and
the history (Sect. 53.1.3) of the field, Sect. 53.2 describes physical therapy and
training robots, and Sect. 53.3 describes robotic aids for people with disabilities.
Section 53.4 then review recent advances in smart prostheses and orthoses tha are
related to rehabilitation robotics. Finally, Sect. 53.5 provides an overview of recent
work in diagnosis an monitoring for rehabilitation as well as other health car ssues.
The various areas of rehabilitation robotics focus on different user populations, but a
common characteristic of these populations is that they have a disability. Disability is
defined in the Americans with Disabilities Act as “a physical or mental impairment
65
that substantially limits one or more of the major life activities.”
In the industrialized countries (e.g., Japan, US, Canada,and Europe), the incidence of
disability varies between8% and 20%, with differences likely due primarily tovarying
definitions of disability and reporting conventions(Table 53.1). Age is a risk factor for
disability, andlower birth rates and life-extending health care are thedominant factors
contributing to the aging of the populationand a concomitant rise in disability. In
China,the population control policies of the 1970s have createda lack ofworking-age
adults to support the economy. Thedisproportionate incidence of disability in the
elderlypopulation makes it clear that developers of rehabilitationrobotics will also be
faced with users who, asa demographic group, generally have lower levels ofsensory
and motor capability, and may have impairecognition as well. The urgency of making
advances inthis field is increasing in line with these demographic changes.The history
of rehabilitation robotics is almost as old asthat of robotics itself, although emanating
from very differentsources. Several books, chapters, and papers havebeen written on
the history of rehabilitation robotics inmore detail than this section [53.1, 7, 8], and
numerouspapers in the proceedings of the Institute of Electrical and Electronics
Engineers (IEEE) International Conference on Rehabilitation Robotics also provide
more grounding for historical perspective. The chronology below pays particular
attention to early work and to projectswith notable clinical and/or commercial impact.
Early robotics, starting in the late 1950s, focused on large manipulators to replace
workers in factories for dirty, dangerous, and undesirable tasks. The earliest
rehabilitation robots came from the field of prosthetics and orthotics (P&O). The Case
Western University arm (1960s) and the Rancho Los Amigos Golden Arm(early 1970s)
(reviewed in [53.7]) were both adaptations of replacement mechanical arms meant as
powered orthoses [53.1]. The user drove the Golden Arm with a set of
tongue-operated switches, joint-by-joint, an arduous means of endpoint control. In the
mid 1970s, the Department of Veterans Affairs began funding a group at the Applied
Physics Lab under the guidance of Seamone and Schmeisser to computerize an
66
orthosis mounted on a workstation to do activities of daily living (ADL) tasks such as
feeding a person and turning pages [53.9]. For the first time, a rehabilitation robot had
a command-type interface, not just a joint-by-joint motion controller. The 1970s
also saw the French Spartacus system being developed, guided by the vision of Jean
Vertut, for use by people with high-level spinal cord injury as well as children with
cerebral palsy [53.10]. This system did not emerge from the P&O field but was
developed by the French Atomic Energy Commission (CEA), which used large
telemanipulators for nuclear fuel rod handling. One of these was adapted so that
people with movement impairment could control it using a joystick for pick-and-place
tasks. A decade later, one of the researchers on the Spartacus project,Hok Kwee,
began the MANUS project, a dedicated effort to develop the first wheelchair-mounted
manipulator designed expressly as rehabilitation robot, not adapted from a design
from another field. However, in between, several other major programs were begun.
In 1978, at Stanford University, and then with decades-long funding from the US
Department of Veterans Affairs, Larry Leifer started the vocational assistant robot
program, culminating in several clinically tested versions of the desktop vocational
assistant robot (DeVAR) [53.3,11,12], amobile version, themobile vocational assistant
robot (MoVAR) [53.13], and finally the professional vocational assistant robot
(ProVAR), which had the advanced ability for the user to program tasks in an
easy-to-use browser-type environment [53.14]. This step was made since, although
DeVAR made it briefly onto the market in the early 1990s, multisite user testing
revealed it was still too costly for the functionality it had: ProVAR development
ensued, then continued by Machiel Van der Loos. All these versions were based on the
Puma-260 industrial manipulator to achieve robust, safe operation. Research shifted in
2006 to the VeteransAffairs (VA) in Syracuse, NY, to integrate sensing and
autonomous features and explore new, more cost-effective manipulator options.
In the mid 1980s, from observations on the unsuitability of existing industrial,
educational, and orthosis-derived manipulators for rehabilitation applications, Tim
67
Jones at Universal Machine Intelligence (later Oxford Intelligent Machines, OxIM) in
the UK began an intensive effort to provide the rehabilitation robotics community
with its first workhorse system specially designed from the ground up for human
service tasks. Over ten years, a series of systems, starting with theRTXmodel, were
used in numerous research labs and clinics around the world. The most extensive
effort to use the OxIM arm was in France, and a suite of research projects, funded by
the French government and the European Research Commission, starting as the robot
for assisting the integration of the disabled (RAID), then as MASTER [53.15],
developed and clinically tested workstation-based assistive systems based on the RTX
and subsequent OxIM arms. When OxIM ceased building its arms, the French
companyAfma Robotics [53.16]took over efforts to commercialize
theMASTERsystem, which it continues to do today
