8Definitions
- Orientation and mobility for young children are
- defined as follows
- Orientation can be defined as knowing oneself as
a separate being, where one is in space, where
one wants to move in space, and how to get to
that place (Anthony, 1993, p. 116). - Mobility refers to motor development, including
the normal integration of reflexes, acquisition
of motor milestones, refinement of
quality-of-movement skills, and purposeful,
self-initiated movement (Anthony et al., 2002,
p.328).
1G
9History of Orientation and Mobility
- OM emerged as a field and a profession in
the late 1940s as rehabilitation for veterans who
lost their vision during World War II. - The first university preparation program for
orientation and mobility specialists (OMSs) began
in 1960 at Boston College. - In 1962, the Vocational Rehabilitation
Administration awarded grants to 22 states to
fund OMSs. - Joffee Ehresman, 1997
- Weiner Sifferman, 1997
1H
10History of OM
- In the mid-1960s, the U.S. Office of Education
began to sponsor university programs that
prepared OMSs to work with children and youths
with visual impairment. - Young children did not receive OM until the
late 1980s, following the passage of PL 99-457
in 1986. - Wiener Sifferman, 1997
1I
11History of OM
- In 1997, special education laws were reorganized
under the Individuals with Disabilities Act
(IDEA). Part C of this act entitles infants and
toddlers with disabilities to access to early
intervention. - In 1997, IDEA was also amended to include OM as
an early intervention service under Part C. In
Part B, OM is clearly defined as a related
service for children with visual impairments ages
3 to 21 years.
1J
12History of OM
- Initially, OM techniques for adults and older
children were modified for younger children. - More recently, clinicians have identified early
areas of development, such as object concepts,
spatial relationships, body awareness,
attachment, etc., that impact the development
of OM skills. - This developmental perspective has helped to
shape the actual definitions and program
components of OM for infants and toddlers.
1K
13Developmental OM
- A developmental approach to OM is based on the
premise that the foundation for OM skills is
built during infancy and early childhood. - OM concepts and skills are developed in the
childs home environment and community. - OMSs need a solid understanding of early
childhood development. - Anthony et al., 2002
1L
14Family-Centered Practices
- In order for early intervention to be as
effective as possible, families must be involved.
- Families contribute unique information about
their childrens development, preferences, and
needs. - Developmentally appropriate and family-centered
practices embrace diversity, use a
transdisciplinary model of intervention, and
value natural learning opportunities. -
Hatton, McWilliam, Winton, 2003
1M
15Natural Learning Opportunities
- Orientation and mobility intervention for young
children should be embedded into the familys
daily routines and activities. - Family routines are valuable natural learning
opportunities that promote the attainment of
functional outcomes. - Functional outcomes (desired goals based on
family priorities) enhance childrens development
and improve the quality of life for children and
families. - Hatton et al., 2003
1N
16Transdisciplinary Support
- A primary early interventionist, collaborating
with other team members, provides direct support
to the family. As required by Part C of IDEA
(1997), the team should be comprised of
individuals from various disciplines. - Role release, a significant component of
transdisciplinary support, is the sharing of
expertise specific to the disciplines of other
team members, including family members, and the
undertaking of new roles while mastering specific
skills. - Hatton et al., 2003
1O
17Components of Early OM
- Developmental OM programs for infants and
- toddlers should include the following components
- sensory skill development,
- concept development, and
- motor development (including purposeful
- and self-initiated movement).
- Additional components for preschoolers include
- environment and community awareness and
- formal orientation and mobility skills.
- Anthony et al., 2002
-
Dodson-Burk Rosen, 2002 -
Hill, Rosen, Correa, Langley, 1984
1P
18Components of Early OM
- Anthony et al. (2002) recommend the following
- components
- Orientationto expand childrens body concepts,
daily settings, and locations within each
environment - Mobilityto encourage and refine independent
movement (including the use of mobility devices) - Purposeful Movementto reinforce childrens
reasons to move in different environments - Environmental analysis for safetyto assist the
family and transdisciplinary team in analyzing
natural environments, to ensure self-initiated
and purposeful movement
1Q
19Sensory Development Roles
- Collaborate with the family
- to ensure that proper medical
- evaluation of vision and
- hearing has occurred.
- Appropriately interpret eye care
- and audiological reports.
- Anthony, 1993
1R
20Sensory Development Roles
- Learn about all of the childs sensory
abilities. - Refine the childs ability over time to
respond to and use sensory information based on
mindful presentation of sensory information
in everyday environments and daily routines. - Anthony, 1993
1S
21Sensory Development Roles
- Assist the family and the early intervention team
in implementing appropriate adaptations to
optimize the childs sensory-based learning. - Identify the types of sensory-based motivators
that can be used to entice young children to
move and travel effectively and efficiently. -
Anthony, 1993
1T
22Cognitive Development Roles
- Understand and explain the significance
of cognitive development to the family and
the transdisciplinary team, with particular
attention to - -body concept -spatial
relationships - -positional concepts -object
concepts - -cause and effect -means-end
- -imitation
- as related to motor development, movement,
and orientation and mobility.
1U
23Cognitive Development Roles
- Understand and explain the impact of
blindness or visual impairment on early
cognitive development and motor and movement
development to the family and the team. - Collaborate with the family and the
transdisciplinary team to identify cognitive
skills that will facilitate motor and movement
development.
1V
24Cognitive Development Roles
- Identify and introduce, with the early
intervention team and family, strategies within
daily routines that will facilitate cognitive
development and lead to purposeful and
self-initiated movement in young children with
VI.
1W
25Motor Development Roles
- Collaborate with team members to develop
understanding of the impact of blindness and
visual impairments on motor development and
movement. - Suggest specific strategies to the team that will
promote security, safety, and self-initiated,
purposeful movement in young children.
1X
26Motor Development Roles
- Collaborate with physical and occupational
therapists to ensure optimal motor, sensory, and
movement development through functional
activities within the context of daily
routines and natural learning
opportunities.
1Y
27Roles in Assessment
- Involve the family and other members of the
early intervention team in assessment. In
accordance with Part C of IDEA, the assessment
should involve at least two separate disciplines
and include the familys priorities and concerns.
1Z
28Roles in Assessment
- Use a family-centered, routines- based, and
developmental approach for assessment and
intervention based on knowledge about early
childhood development and appropriate
interpretation and application of OM concepts
and skills for infants and toddlers.
1AA
29Attachment and Mobility
- Secure attachment is believed to be related to
the willingness of infants to venture out into
the environment to explore and experience it. - Infants early social-emotional responses elicit
and maintain proximity and interactions with
other people for protection and survival, and
facilitate development in all domains. - Warren Hatton, 2003
1BB
30Attachment and Mobility
- Social referencing provides children with
- the self-confidence to move and explore.
- Severe visual impairment may impede
- exploration and movement
- by making attachment more challenging,
- by possibly decreasing motivation to move out
into the world to explore it, and - by making it difficult or impossible to glance
back at the caregiver (social referencing) during
early exploration. -
- Warren Hatton, 2003
1CC
31Promoting Independence
- Without the ability to visually monitor the
environment, children with visual impairments may
exhibit wariness. - Families, caregivers, and interventionists of
infants who are blind must be extraordinarily
persistent in motivating their children to move
out into the world. - Often, families and caregivers also must overcome
their own fearfulness and tendency to be
overprotective. - Lowry Hatton, 2002
1DD
32Promoting Independence
- Independence requires active involvement in a
wide range of daily routines at home and in
childcare centers (clean-up, meal times,
dressing, etc.) - Participation does not need to be complexit can
be very simple and brief for young children.
1EE
33Promoting Independence
- Strategies to facilitate independence in
daily - routines include
- hands-on involvement with all materials
- allowing children to help
- encouraging reaching for nearby objects
- orienting children to small areas of the room
and - setting up play spaces with objects in
predictable - locations.
Lowry, 2004c
1FF
34Promoting Independence
- Strategies to facilitate independence in daily
routines include - arranging furniture, equipment, and toys
- in stable and predictable locations
- providing adult-mediated play with
- opportunities for self-initiation and choice
- making
- using short miniroutes to move into and
- out of motivating daily routines and
- receiving support from an OMS.
-
Lowry,
2004c
1GG
35Precautions
- Opportunities for unrestricted movement and play,
however crucial to development, present greater
challenges when children are not able to visually
monitor obstacles and other hazards. -
- Simple precautions should be taken, not only
to offer greater safety for children, but to
provide ease of movement and to reduce stress. -
Lowry, 2004d
1HH
36Facilitating Ease of Movement
- Provide appropriate supervision while
respecting childrens independence. - Keep furniture, equipment, and other
- landmarks in predictable locations.
- Keep travel paths clear.
- Use simple verbal cues to alert the
- child to the presence of an upcoming
- obstacle.
- Lowry, 2004d
1II
37Facilitating Ease of Movement
- Reposition or remove low-lying and
- head-high obstacles.
- Offer extra supervision outdoors.
- Add foam padding temporarily to sharp
- edges.
- When appropriate, use a modified guide
technique that involves having the child - hold onto the adult.
- Lowry, 2004d
1JJ
38OM Mobility Techniques
- Hand searching represents goal-directed reaching
at its best. In infancy, encouragement and
opportunities to reach for toys from all postures
help to prepare children
for more extensive searching
later on. Postural readiness and
cognitive skills will determine
when the infant
is able to search.
1KK
39OM Mobility Techniques
- Trailing involves lightly following
- walls or furniture to move from one
- point to another. It is important for
- verifying orientation through recognition of a
known landmark, - moving a short distance efficiently from one
point to another, and - locating a specific landmark, object, or access.
1LL
40OM Mobility Techniques
- Upper body protection is used to avoid injury
above the waist while walking.
It is especially helpful for use in
less familiar areas and with children who have
just started walking.
Anthony et al., 2002
1MM
41OM Mobility Techniques
- Guide technique is a method of physically
guiding the child when walking together, while
providing the child with a greater
sense of responsibility and control. -
Anthony et al., 2002
1NN
42Mobility Devices
- Pushcarts and other commercially
- available push toys may help to develop
- concepts that will transfer to long cane use
- later on, such as
- use of a tool to gather information about the
environment, - use of an intermediate object to protect, and
- how to plan motor correction around obstacles.
- Anthony et al., 2002 Clarke, 1988
- Lowry
Hatton, 2002 Skellenger Hill, 1991
1OO
43Mobility Devices
- Adaptive mobility devices (AMDs) are tools
- with special modifications designed to meet
the - needs of children who cannot easily use the
- traditional long cane.
- Some of these include prescriptive single and
double handles, wheels, and other auxiliary
roller devices to improve ease of movement. - The basic AMD is made of PVC pipe and is
rectangular in shape. -
Anthony et al., 2002 Farmer Smith,1997 -
Foy et al., 1991 Lowry Hatton, 2002
1PP
44Mobility Devices
- AMD advantages
- Designed to be used with two hands, offering
protection with minimal cooperation and effort - When well designed, is easy to use and therefore
can often be introduced to younger children - Many children seem to enjoy an immediate sense of
protection and freedom. - Offers a greater arc of protection than typical
preschool cane use - Lowry, 2004a
1QQ
45Mobility Devices
- AMD disadvantages
- Use of two hands not very compatible with
trailing - Awkward to use in crowded or narrow spaces
- Unsafe for use in ascending or descending steps
- Difficult to use over many outdoor surfaces
- Presents greater storage difficulty
-
Lowry, 2004a
1RR
46Mobility Devices
- Long cane advantages
- Frees up one hand to trail, locate
- objects, place hand on railing, and
- confirm orientation
- Provides early experience with the
- actual device that will be used later
- More easily used safely on steps
- Easy to store
- Lowry, 2004a
1SS
47Mobility Devices
- Long cane disadvantages
- Requires more mature attention and
- motor skills to keep the device in front
- With typical preschool use, tends to
- leave broad areas of body unprotected
- More likely to tempt use as a weapon
- More challenging to introduce to younger
- and orthopedically involved children
- Lowry, 2004a
1TT
48Readiness for Mobility Devices
- The OMS, the TVI, the family, and other
- team members should consider several
- factors in determining when to introduce
- a device.
- Does the child walk with good stability and hands
held at waist-level or lower? - Does the child show interest in the device?
-
Lowry,
2004b
1UU
49Readiness for Mobility Devices
- Is the family supportive and accepting of the
device? - Does the child understand cause and effect?
- Can the child maintain grasp of the device
without assistance for a significant period of
time?
-
Lowry, 2004b
1VV
50Readiness for Mobility Devices
- Does the childs inability to visually detect
obstacles and drop-offs indicate the need for a
mobility device? - Does the child spend time regularly in a setting
appropriate for use of a device, i.e., settings
other than the home, such as a childcare
center, mall, department store, supermarket,
church building, etc.? - Lowry, 2004b
1WW
51Introducing AMDs or Long Canes
- Give the child plenty of time to explore the
device. - Sit down with the child and tell her that you
brought a new device to help her when she
walks. - Tell her the name of the device (e.g.,
cane, AMD). - Sapp, 2004
1XX
52Introducing AMDs or Long Canes
- Tell her that she will get to walk with it in a
little while, but first you are going to look at
it while sitting down. - Remind the child that she cannot swing the AMD or
cane, because she might hit someone. - Hand the child the AMD or cane and give the child
plenty of time to explore it. - Sapp, 2004
1YY
53Introducing AMDs or Long Canes
- The child may choose to feel it, look at it,
smell it, or even taste it. As the child is
exploring the device, name the different
parts. - Some children may want to name their devices
just as they name stuffed animals. - Sapp, 2004
1ZZ
54AMDs First Lessons
- Most children will need several simple lessons to
begin using the AMD. - These lessons should involve a motivating goal to
reach and a short, clear path to the goal. - Some lessons may only last a few minutes due to
the childs short attention span. - Sapp, 2004
1AAA
55AMDs Advanced Lessons
- Once the child is able to use an AMD
- to travel a cleared path, you can begin
- teaching the child more advanced
- skills, such as
- obstacle detection,
- drop-off detection,
- and
- trailing.
- Sapp, 2004
1BBB
56Parent Involvement
- Encourage parents to become involved in their
childs AMD lessons. - Encourage parents to provide children with daily
opportunities to practice in appropriate
environments. - If parents are resistant to allowing the child to
use the AMD, ask them to identify one time each
week when the child can practice with the device.
- Sapp, 2004
1CCC
57Long Canes First Lesson
- Most children will need several lessons to
practice on short, clear paths with their cane. - Hard floor surfaces and mushroom or ball tips
will help the cane to slide more easily than
carpeting or pencil tips. - During this practice, stress two issues with the
child and the parent (1) keeping the cane in
front of the child, and (2) keeping the cane tip
on the ground. -
Sapp, 2004
1DDD
58Long Canes Advanced Lessons
- Many children can begin learning more
- advanced cane techniques at very early
- ages, including
- obstacle detection,
- drop-off detection, and
- trailing.
- They might not fully master these skills
- until preschool or elementary school age.
- Sapp, 2004
1EEE
59Parent Involvement
- Some children will be ready to use a cane with
their families as soon as it is introduced, while
other children will require several instructional
sessions with an OMS before they are ready to use
a cane with their parents. - If a child is allowed to use a cane improperly
even for a short time, it can be difficult to
relearn correct cane position. -
Sapp, 2004
1FFF
60Transitioning AMD to Long Cane
- Some children learn to use an AMD and a long
cane simultaneously with frequent opportunities
to choose which one to use. - Other children, especially those with additional
disabilities, use an AMD for months or even years
before beginning to use a cane. Some children
begin instruction with a long cane with no
experiences with an AMD. - Sapp, 2004
1GGG
61Transitioning AMD to Long Cane
- When a child is transitioning from using an AMD
to using a long cane, it is important not to
assume that the child will automatically
generalize skills from one device to another. - Begin by introducing the cane as described
earlier and then move through initial and
advanced lessons. - Sapp, 2004
