Children learn about their
environment as they move through itabout people and objects, sizes,
shapes, and distances. For typically developing children the senses of sight
and hearing provide the greatest motivation for exploration. These children
will use their vision and hearing to gather information about their
surroundings while growing in understanding of their own bodies and their own
capabilities of movement. The sight of toys or people and the sounds of voices
or objects encourage them to move and discover. As they do so, they gather,
recognize, and interpret an amazing array of sensory information.
A child who is deafblind must learn to understand his or her
environment with minimal or distorted visual and auditory information. Limited
sight and/or hearing may inhibit natural curiosity and the motivation to move
about. As a group, learners who are deaf-blind are quite diverse and may
include children with physical, cognitive, or health problems in addition to
combined hearing and vision losses. Some may feel insecure or frightened when
moving about in an environment they can neither see nor hear clearly. Others
may run on the track team or use motorized wheelchairs. Some communicate with
speech or sign language, while others may not have had enough experiences in
the environment to understand even basic concepts about that environment or
about objects found in it. It is essential that children who are deaf-blind
receive learning opportunities and instruction that facilitate purposeful
movement.
Orientation and Mobility (O&M) instruction provides students
who are deafblind with a set of foundational skills to use residual visual,
auditory and other sensory information to understand his or her environment.
For the child who is deaf-blind, movement is an opportunity to gather sensory
information, to communicate, and to make choices. O&M instruction provides
opportunities and skills that can broaden the students awareness of the
environment, resulting in increased motivation, independence and
safety.
Consider the following example: Alex, a sighted and
hearing child, is playing with Jason, his brother who is deaf-blind, in their
bedroom. When Alex hears the front door opening, he assumes his mother has come
home from work. This interpretation is reinforced when he hears the family dog
barking excitedly. Wishing to greet his mother at the door, he quickly walks
from his bedroom, safely avoiding the many toys scattered on the floor,
continues traveling down the hall, moving through the kitchen and around the
dining table. While running to greet his mother, he sees that she is carrying a
large square cardboard box. Immediately recognizing the logo from his favorite
pizza restaurant, he knows she has brought home his favorite dinner, a
pepperoni pizza. Excitedly, he offers to carry the box back to the kitchen and
completes this task successfully and proudly.
In this rather routine event, spanning only a few minutes, Alex
has gathered and interpreted much visual and auditory information. Not only
does he understand that his mother is home, but also that he can greet her at
the front door if he hurries, and that they are about to eat his favorite meal.
In moments, the sensory information he gathered and processed provided him easy
access to his environment, allowing him safe movement through the house. Seeing
the pizza box also provided him with clues about immediate future activity.
For Jason, however, the scenario is a bit different. He knows
someone has entered the house because he was playing with the dog when the
animal suddenly became excited, began to bark, and then ran out of the room.
Jason may sense or hear some of this activity by partially seeing or feeling
the dog alerting him. As the result of his O&M instruction, he now travels
down the hall using a protective technique to move safely around the toys. He
moves through the kitchen and around the dining table. By now, he can smell the
pizza and becomes excited because pizza is one of his favorite foods. His
O&M training has taught him how to move safely through his environment,
determining where his mother might be. His mother greets him, allows him to
feel the warm box, and communicates that she has brought home pizza. The mother
and son use guided travel to walk to the kitchen.
From O&M instruction, Jason has learned to interpret and
utilize available sensory information.
He knows how to move safely through the environment and he is
rewarded with success in finding out what he wanted to know.
What is O&M for the Child Who Is
Deaf-Blind?
Orientation skills allow us to know where we are, where
we are going, and how to think about and plan strategies for getting to a
destination. Mobility involves the actual movement from place to place.
Along with communication skills and daily living skills, O&M skills are
essential for all children who are deaf-blind. The ability to understand the
environment and to move safely within it is an important component of future
development, success, and independence.
O&M instruction for individuals who are deaf-blind is
designed to teach them to move as independently and as purposefully as they are
able. For some children who are deaf-blind, it is reasonable and desirable to
expect that they will move about independently in both indoor and outdoor
environments. This independence may mean using a long white cane to cross
streets successfully and learning to use city transportation systems. For
others, O&M instruction will provide the skills necessary to allow
independent movement within the classroom or within the home. At a more basic
level, and for children with limited motoric capabilities, increased
independence will mean that they have better developed residual senses and can
more fully understand and interpret information from their environments. They
may come to understand where an object is located and where the object is in
relation to their own bodies. They will have the ability to move with purpose,
perhaps to extend an arm or roll to obtain that object.
While outcomes and expectations may be different for the student
who is deaf-blind, the instruction is similar to that for a child with only
visual impairment or blindness. The most important adaptations are those
related to communication. The O&M instructor will need to ensure
that instructions are given to the student in his or her primary language. This
may require the use of an interpreter and the development of touch cues or
object cues. Certain accommodations that enable the student to interact with
the public also need to be developed. For some children, the lack of auditory
and visual input may have severely limited opportunities to learn about his/her
environment and to develop the language to talk about it. O&M instruction
must often be augmented by hands-on learning to make up for the childs
lack of prior experience. Language instruction is an integral part of any
O&M training experience.
A Team Approach
Originally designed to assist veterans blinded in war, O&M
techniques and instruction have broadened over the past few decades to include
children who are blind or visually impaired and, more recently, children who
are deafblind, children with multiple disabilities, and infants and toddlers
who are visually impaired. The 1997 reauthorization of the Individuals with
Disabilities Education Act (IDEA), Public Law 105-17, identifies orientation
and mobility as a related service that teams may consider in the development of
the IEP. Early focus on O&M instruction is essential for the child who is
deaf-blind to develop the skills needed to travel and move independently about
the environment.
A team approach is vital in the development and implementation
of O&M instruction. A team may be composed of a parent, regular and special
education teachers, other related services personnel, a representative of the
local education agency, other individuals who may have special knowledge
regarding the child and, where appropriate, the child. Each team member brings
a unique perspective to the development of an appropriate educational program.
The O&M specialist will participate in team-based assessments of the child
and works collaboratively with all team members, including the parents, to
address the unique O&M needs of the child. The O&M specialist also
provides the team with activities that reinforce movement skills and promote
understanding of the environment. He or she assists in analyzing the home and
school environments and makes recommendations for strategies that may improve a
childs ability to travel within, and better understand, these
environments. The O&M specialist may be involved in directly teaching the
child specific skills he or she needs to travel safely and will share these
with other team members so each can reinforce them with the child. The O&M
specialist may also work with other team members to ensure that each
understands and shares in the responsibility of supporting an appropriate,
individually developed O&M instruction program that reinforces movement,
promotes orientation, and encourages independent travel and purposeful
movement.
Instructional Strategies
It is best to view O&M instruction, as identified in the
students IEP or IFSP, as a process that begins with assessment. The
process is cyclical and ongoing.
Once a program is developed and implemented, the evaluation is
ongoing, with data used to inform decisions about changes that may be necessary
for instruction. All instructional components of each childs program must
be continuously evaluated for effectiveness, with modifications made as
necessary.
Assessment
Initial assessment of O&M skills provide the foundation for
future program planning. The O&M specialist will work closely with other
team members to identify and implement appropriate assessment techniques.
Assessment may include the following:
- Informal student observation, conducted in natural
environments in which the student interacts (home, school, etc.).
- Assessment of communication skills and necessary
adaptations.
- Parent/caretaker interviews.
- Formal assessment of orientation and mobility skills.
- Assessment of learning modalities.
- Developmental assessment of:
- Sensory skills.
- Cognition.
- Motor skills (gross and fine).
- Environmental analysis. Environment analysis is a key
component of the assessment process. The various environments in which the
student is involved should be assessed for safety. The need for any
modifications that may enhance a childs ability to travel in and
understand the environment should also be assessed.
Program Development and Implementation
Communication. Developing ways to communicate presents
the most significant challenge for children who are deaf-blind. Communication
issues must be addressed in every aspect of instruction. For example, planning
for instruction in areas such as concept development must take into account
that although the child may be able to perceive the shape or configuration of a
hallway intersection, he or she may need to be taught the specific language
(triangle or corner) for that perception.
Children who are deaf-blind use a variety of communication
methods including tactile sign language or American Sign Language (ASL),
speech, gestures, fingerspelling, augmentative devices, pictures, objects, body
movements, behavior, and facial expressions. Instruction strategies must
incorporate the childs primary communication methods.
Motor development includes both gross and fine motor
skills and focuses on developing and/or enhancing a students motor
abilities. These skills involve large muscle movements such as walking or
running, as well as the finer skills associated with hand and wrist
movements.
Concept development is closely linked to general
cognitive development. It involves the understanding of sizes, shapes, and
functions of objects, as well as spatial and positional relationships. It
includes the awareness and knowledge of ones own and anothers body,
an understanding of the body parts, of their movement capabilities, and of body
part relationships.
Concept development also incorporates an understanding of and
knowledge about the environment. For example, a child who is deaf-blind may not
understand the concept of a multistory building without specific
instruction. He may know that hes walked up a flight of stairs, but does
he understand that he is above the hallway he just was in? Does he
know that there may be several stories still above him?
Sensory development optimizes a students ability to
utilize the senses of residual sight and hearing, as well as the tactile,
olfactory, and kinesthetic senses. Most students who are deaf-blind have
residual hearing and/or sight, and instruction can be provided to help them
learn to use this sensory information to understand and interpret information
they are gathering through their senses. It is important to teach the child to
interpret sensory information, assisting him or her to use this information for
purposeful movement.
Orientation skills enable the student to use sensory
information to move purposefully in the environment. Orientation skills
instruction is designed to teach the student to use environmental cues (e.g.,
sounds, smells, and visual or tactile stimuli) to provide information about the
present location and information about this location relative to other locales.
For example, a child may learn to recognize that she is in the kitchen from the
smell of coffee brewing or the living room because of the sensation of the
carpet beneath her feet. This information enhances her understanding about the
environment and how to move within it.
Mobility skills incorporate those O&M techniques that
promote movement through the environment with safety and ease. These skills
include walking with another person (guided travel), self-protection skills,
and cane travel. For some, these also include the use of dog guides and
electronic travel aids. For young children, these mobility skills will include
early purposeful movements such as crawling and walking.
Evaluation
All goals and objectives in the IEP should have stated criteria
so team members can evaluate the childs progress and the effectiveness of
the instructional strategies. It is essential that team members understand IEP
goals and objectives and the criteria established for each. All strategies
implemented into a childs educational program must be evaluated for
effectiveness and changed as necessary.
The Basics of Mobility Skills
Numerous curricula discuss mobility skills and techniques that
are appropriate for students who are deaf-blind (see resource list). These
skills and techniques provide methods of movement through the environment that
make the child feel safe and able to participate. Basic information is
presented in order to provide an overview of the different types of mobility
skills and a better understanding of the purpose of each skill. For additional
information, it is necessary to consult with an O&M specialist who can help
to refine and individualize specific mobility skills appropriate for a
particular child, develop individualized instructional programs, and recommend
additional resource information.
Guided Travel
Many refer to the mobility technique involved in walking with
another person as Sighted Guide Travel." However, it is not necessary to
be sighted to be an effective guide, and, therefore, the terms Guided
Travel and Human Guide are also used. Using this technique,
the deaf-blind child maintains a constant grip on the guides arm (figure
1) while following the guide around obstacles as they travel through the
environment. To maintain a grip that allows active participation in travel, the
child must grasp the guides arm so the thumb is placed on the outside,
with the remaining fingers gripping the inside of the arm (figure 2). The child
is half a step behind and to the side of the guide, allowing the guide to give
cues about the environment through arm movements, such as cues to
indicate they are approaching stairs, doors, or narrow spaces. The guide can
move the guiding arm behind his or her back to indicate that they are
approaching a narrow space and must walk single file. Other cues can be given
to indicate stairs and doors.
Figure 1 Figure 2
Cues need to fit each childs communication and learning
styles. For example, children who are blind will learn that the cue for
stairs involves a pause from the guide when they have arrived at
the base of the stairs. Children who are deaf-blind may find it helpful to
enhance this cue by having the guide sign stairs and pause as they
approach the stair case. Some children find it helpful to locate the stair
railing before ascending or descending. A common adaptation for smaller
students to the basic guided travel technique is to have the
student grasp the guides extended fingers, wrist, or forearm rather than
maintaining a grip above the elbow (figure 3). Effective guided travel involves
a partnership between guide and child with both participants actively
involved.
Figure 3
Protective Techniques
Protective techniques allow students to travel independently,
yet safely, in familiar places, enabling them to locate objects while
protecting their bodies. Protection skills are primarily used in familiar
indoor environments and are designed to provide information about the
environment during travel. Upper hand and forearm protection skills (figure 4)
in which the arm is bent and held across the body at shoulder height, parallel
to the floor, with the palm facing outward and the fingertips extending beyond
the opposite shoulder, will provide protection from objects the student may
contact at head and chest level.
Figure 4
Lower body protection (figure 5) with the arm extended down and
held diagonally across the body, provides protection from obstacles at waist to
upper leg level. These two techniques are sometimes used together, but they can
be fatiguing. Typically, neither technique is used continually, but rather is
employed as needed. For example, an individual may use trailing skills (see
trailing below) while walking down a familiar hallway and use the
forearm protection technique only near the end of the hall because he knows
that there is a door that is often left open and he wants to locate it without
injury.
Figure 5
Trailing
While trailing, a student will extend the arm at about 45
degrees, holding the arm to the side and slightly in front of the body while
maintaining contact with a surface, such as a wall. This technique (figure 6)
can provide a student with a method of maintaining alignment. It also provides
some protection during travel, as well as some information about the
environment. This skill can be used in a variety of situations. Examples
include traveling down hallways while looking for a specific object such as a
door, or when a student wants to achieve a straighter line of travel to
maintain orientation, or while traveling along the outside of a building while
locating a way in. Trailing is also sometimes used along with a mobility
device, or in conjunction with upper hand and forearm protection (figure
7).
Figure 6 Figure 7
Mobility Devices
There are many mobility devices that can, when properly used,
provide a student with the means for independent, safe, efficient travel. The
most commonly recognized mobility device is the long white cane. Many other
mobility devices are also available, including adapted cane devices. Mobility
devices serve as an extension of the users arm(s), hand(s),
and fingers, and provide protection from obstacles while allowing access to
needed information about the environment. There are many theories about the
selection of mobility devices, on the best times to begin instruction, and the
skills necessary to warrant instruction with a particular device. It is vital
that the students team work closely with an O&M specialist in making
decisions regarding the use of mobility devices.
Dog Guides
Some individuals who are deaf-blind prefer to use dog guides
rather than canes. Dog guide use is taught at special dog guide schools. Most
of the schools work primarily with adults who are blind or visually impaired,
but there are several that offer their services to individuals who are
deaf-blind as well. Most training programs provided at the schools involve four
or more weeks of instruction, with many providing follow-up instruction in the
students home environment. It is important to remember that an individual
who chooses to use a dog guide still maintains responsibility for his or her
own travel. The dog does not assume responsibility for orientation, nor does it
make decisions about safety. Most dog guide schools require that their students
be skilled travelers before being accepted into the training program.
Individuals who are considering a dog guide must also understand that there are
additional responsibilities in caring for their dog, including the daily
feeding, grooming, and toileting issues. Most dog guide schools prefer to admit
only students who are past high school age, although some do work with younger
students.
Electronic Travel Aids
Electronic Travel Aids (ETAs) are portable devices that emit
sonar or laser signals that are reflected back to the user during travel, and
are converted to auditory and/or tactile signals. The devices are hand held, or
chest, head, wheelchair, or cane mounted, and usually serve to provide
supplementary information during travel. Individuals using ETAs can learn to
interpret information they receive from the device about obstacles that may be
in their direct path, about openings in hallways, and about
drop-offs or inclines in the travel surface. They may also be used to enhance
trailing abilities.
Wheelchair Mobility
Any O&M program for students using wheelchairs must be
highly individualized and must take into account the students residual
senses, his or her ability to operate a chair with one hand, and the potential
use of a motorized wheelchair. In addition to the O&M specialist, the
students physical therapist and occupational therapist must be actively
involved in all decisions regarding mobility for wheelchair users. Some general
considerations for O&M instruction for students who are wheelchair users
are presented here:
- Students who are able to operate the chair with one hand can
be taught modified guided travel techniques. These techniques will allow them
to gather additional information during travel.
- Some wheelchairs can be adapted by adding an extended
bumper that will serve as an extension of the wheelchair, and act
as a mobility device.
- Adding foam to the front of the chair can serve as
additional padding to lessen the impact when detecting obstacles with the
chair.
- Trailing skills can be utilized while traveling in a
wheelchair. Students who operate their chairs with one hand can trail using the
other. For students not able to operate the chair with one hand, curb
feelers can be mounted on the side of the wheelchair. The student can be
taught to trail using the curb feelers. Even when someone is pushing the chair,
trailing can be used so that the student can gain information about the
environment, thereby enhancing his or her ability to maintain orientation.
- The students physical therapist and occupational
therapist can help teach the student to open and close doors.
- Some students are able to use a long cane while using a
wheelchair. This is true for students who are able to operate the chair using
one hand, and for those who use motorized wheelchairs. Most often, the cane
chosen for use with a wheelchair is longer than a typical cane.
- Instruction in interpreting information about the travel
surface is important. The student can learn to discern the way different
surfaces feel while traveling over a variety of surfaces such as,
the gravel, grass, or sidewalks. This skill provides general environmental
orientation.
- Using the students communication mode or system, the
person who is pushing the chair (in effect, guiding the student)
should use strategies that encourage active student participation during
travel. The student has a right to know where he or she is, where he or she is
going, and what the environment is like. This information will encourage the
student to actively learn from the environment rather than simply
sit during travel.

For some students an interpreter is critical for teaching
orientation and mobility (O&M) for numerous reasons, including the
following:
- Clear and convenient communication is essential for
establishing rapport. In turn, building rapport is basic to establishing a
sense of trust and confidence for the student who is learning O&M
skills.
- The aim of O&M instruction is safe and independent
movement, and maintaining safety depends on the accurate communication of
information.
- Students who are receiving O&M instruction may have a
variety of questions and concerns. It is difficult to address their concerns or
to be confidential when communication is impaired.
How do teachers, O&M instructors, and others work with
interpreters during O&M instruction?
- They all work as a team.
- The O&M instructor needs to prepare the interpreter by
teaching him or her O&M concepts and techniques, including sighted guide
and basic cane techniques.
- The O&M instructor retains his or her teaching role; the
interpreter works to make things clear; and the two consult with each other
frequently. The O&M instructor checks the interpreters sighted guide
techniques and interpretation and provides the student who is deaf-blind with
tactile experiences as often as possible.
- Goals and methods need to be modified during instruction as
all members of the team refine their methods of communication and see how the
student is progressing.
- Because working with an interpreter may be a slow process,
patience is essential.
- Success depends largely on the student and the rapport and
quality of communication between the student and the professionals with whom
the student is working.

Practical Strategies For Families and Team
Members
- Provide opportunities for your child or student to explore
all areas of his or her environment, particularly the home. Help the child
locate stationary landmarks that provide reference points. For example, a child
may know that he is in his bedroom after locating his dresser with the
special handles. Be sure to allow him to find this dresser so he
will know when he is in the bedroom.
- Let your child or student experience a variety of surfaces
such as carpet, tiled floors, vinyl flooring, grass, sidewalks, sand, uneven
pavement, etc.
- · Allow your child or student to participate fully in
daily activities and family routines. For example, if he wants to play with
toys, help him go to the place where the toys are located and select the toy
that interests him. Travel back to the play area together. This process allows
him to understand his environment more completely, as compared to having the
toys simply brought to him.
- Make full use of reference points, those clues
that help us know where we are. We have all experienced being lost in an
unfamiliar city, only to become reoriented once we locate a
familiar landmark. Similarly, children who are deaf-blind need to learn to use
reference points to help them stay oriented in their environment. Reference
points can be auditory, tactile, olfactory, or visual.
- Encourage your child or student to travel as independently as
possible. If he can walk independently, allow him to do so. If he is learning
to walk with a guide, dont hold his hand and pull him along with you. If
he is capable of reaching out to locate a desired toy, dont allow it to
magically appear by bringing it to him.
- Be sure lighting is adequate for children who have residual
vision. The use of high contrasts can also assist some students. For example,
using a light rug on a dark carpet may help the child recognize a transition to
a different room.
- Make use of physical boundaries so the child can better
understand his surroundings. It is much easier to comprehend a play area
bounded by wall dividers or bookshelves than an arbitrary space in the middle
of a large room.
- Provide opportunities for the child or student to solve
problems on his or her own. Refrain from rescuing him or her prematurely.
- Provide numerous opportunities for making choices.
- Help a child or student associate familiar toys and objects
with the environments in which they may be used. For example, show him the
washcloth before walking to the bathroom for a bath, or the ball before
traveling to the school gymnasium.
