Kay L. Clarke, Ph.D. – COMS

Slide 2, Where Does our Field Stand on Devices?

Shift in thinking over past 3 decades

Not “IF” but “what”, “when”, and “how”

Cane vs. Alternative Mobility Devices

Anecdotal evidence

Questions remain

Slide 3, Devices in Perspective

Figure 3 Image for disability with four boxes showing wheel chair, sign lanuage, travler with long cane, and cognitive

Devices are not a panacea

o ”No amount of equipment can encourage growth for which inner readiness is not mature” (Breckenridge & Murphy, 1963)

o Emphasis on devices alone does not facilitate purposeful travel

Devices are a single element in a highly complex network of skill areas which enable a child to master the environment


Slide 4, Traditional O&M Components

Slide 20, A Mobility Device as a Tool

Functional device use is a complex form of tool use

Necessitates effectively manipulating the device while navigating through an ever-changing environment

With limited or no visual feedback

Figure 29 Image of a stick figure walking with a white cane


Slide 21, Clues to Making Decisions

Figure 30 Cartoon image of an inspector holding an oversized magnifying glass to his eye

Slide 22

What are early experiences and skills that may prepare a very young child for effective device use?

Figure 31 Cartoon figure scratching its head with a question mark thought above its head


Slide 23, Tool Use Progression

(Schwartz & Reilly, 1981)

Hands - Hands-on exploration

Figure 32 Infant feeding himself with his hand; his face and hand both covered with food

Short, light tools “Transition tool”

Figure 33 Toddler using a child-sized toothbrush

Longer, heavier tools Mobility device

Figure 34 Very young girl walking with a supportive walking toy


Slide 24, Ability to Use Tools

Hands

Figure 35 Child’s hand using a tool to spread paint on paper

Thinking

Figure 36 Graphic of a human head with interlocking gears inside

Spatial Understanding

Figure 37 Child’s hand placing a cube into a shape sorting toy

Experience

Figure 38 Family with two young children sitting down having a meal together


Slide 25, Learning to Use Tools: Hands

Figure 39 Small child’s hand

Hands as first “tools” (Schwartz & Reilly, 1981)

Simple grasp and release

Bang hand-held objects (Kahrs, Jung, & Lockman, 2012)

“Hands-on” exploration of objects

Modify grasp necessary for manipulating various tools (Connolly & Elliot, 1972)

Self-directed use [moving to] external goal (McCarty, Clifton, & Collard, 2001)

Coordinate manual skills & other behaviors occurring simultaneously (e.g., objects carried while walking -- not dropped) (Cratty, 1986)


Slide 26, Learning to Use Tools: Thinking

Figure 40 Cartoon silhouette of child’s head that is filled with bubbles of numbers, letters, music, art, science, etc.

Means-ends relationships (Castle, 1985)

Combining objects in play (Bruner, 1972)

Problem-solving (Claxton, McCarty, & Keen, 2009)

Symbolic thinking (Bates, 1979)

Think about 2 things at once in relation to each other (Newson & Newson, 1979)

Understand tool function - “I cannot identify the thing as a tool if I do not know what it is for…” (Polyanyi, 1958)

Manipulate tool [moving to] Know what tool has contacted (Polyanyi, 1958)


Slide 27, Learning to Use Tools: Space

Figure 41 Young child having a bath in the kitchen sink places its hand on the window sill to balance as it peers into the world outside.

“Space is a puzzlement for young children. Even an older toddler, who has just seen his ball roll under a table, is likely to chase after the ball, retrieve it by ducking under that table and then, forgetting that the space above his head is bounded by the table surface, stand up suddenly and hit his head.” (Honig, 1981 – p. 8)

“Controlling an object may not be as much of a problem as spatial accuracy.” (Keogh & Sugden, 1985)

Localize limbs in space for reaching/grasping

Accuracy by ~ 12 months for sighted children (Keogh & Sugden, 1985)

Readjust perception of location in space when hand is holding a tool

More difficult when limb is moved while holding an object (Keogh & Sugden, 1985)

Implications of limited visual input


Slide 28, Learning to Use Tools: Experience

Many and varied experiences with objects (explore, play with, use) (Vandenberg, 1978)

Integrate knowledge of objects w/ knowledge of body (Schwartz & Reilly, 1981)

Pressure-free “trying out” period in a variety of contexts (Bruner, 1972)

Master sub-skills before using tool functionally (Strelow & Warren, 1985)

Opportunities and expectations (Keogh & Sugden, 1985)

Role of observing others (Deak, et al, 2014)

Familiarity and practice

Focus on tool [moving to] Focus on task (Vandenberg, 1978)

Figure 42 Mother and Baby sitting on floor together playing with kitchen tools


Slide 29, Components for Using a Tool (Schwartz & Reilly, 1981)

Grasp tool with 1 or 2 hands

Localize working edge in space where it will have effect

Manipulate working edge to carry out task

Release tool to end activity

Figure 43 Baby sitting up and playing xylophone with wood mallet

Slide 30, Tool Skill Development

Grasp & Release

“Calibration” – hand in space

“Recalibration” – hand + tool in space

Focus on tool in hand [moving to] Focus on working edge

Skilled manipulation of tool’s working edge

Slide 31

What factors can we use to determine the optimal time to introduce a mobility device for travel purposes?


Slide 32, Introducing Device

Individual differences (Warren, 1994)

Hand, thinking, & spatial skills

Short, light tool use experiences (Schwartz & Reilly, 1981)

“Walking age” and stability

Amount of direct physical exploration

Complexity of travel environment(s)

Experience, understanding, & familiarity with device

Family comfort level & support

Figure 46 Series of children in a progressing from sitting to forward crawl, to quick crawl, to squat, and on to early walking


Slide 33

Can there be costs as well as benefits to early introduction of a device?


Slide 34, Potential “Costs”

Task demand overload Barrier between child and environment: Implications for orientation

Safety concerns

Impact on motor development

Inhibition of child’s travel

“Looks” good…but effective?

Figure 48 Photograph of a woman walking with a young child; the child is holding onto the woman’s hand with one hand and holding a long white cane in the other

Slide 35

Additional Thoughts…

Figure 49 Cartoon lightbulb indicating an idea


Slide 36, Movement or Navigation?

(Pasthas, 1976)

Movement = mechanics of locomotion with no endpoint (“wandering”)

Navigation = goal-directed locomotion

QUESTION: Is this young child simply moving, or moving with purpose, when traveling with and/or without a device?


Slide 37, Moving Through or Interacting With the Environment?


Moving Through = getting from place to place

Interacting With = physically interacting with and learning about the environment along the way

QUESTION: How can we be sure that this young device user has sufficient opportunities for direct interaction with the environment as he travels from place to place?


Slide 38, Device as Intermediary or Barrier?


Intermediary = acts as a mediator / link between child and environment

Barrier = serves as a barricade that separates child from her physical and/or social environment

QUESTION: How can we minimize the barrier effects of this child’s device and maximize the intermediary aspects?

Slide 39, Device Manipulation or Functional Use?


Manipulation = mechanics of physically moving a device

Use = implies that device is serving its intended functions

(developmental support; bumper; probe)

QUESTIONS: Is the device fulfilling its intended functions for this child? If not, are there other device options or ways to continue to improve the use of the current device so it is more functional?


Slide 40

What are important considerations when selecting the best device option for a very young child?


Slide 41, Selecting a Device

Child’s overall development (not age)

Child’s strengths

“Try out” period (options)

Pros and cons of device thoroughly assessed for child

Suited to child’s environment(s) / travel needs

Safety and effectiveness of use (keep records)

Family support / adult monitoring

Figure 55 Cartoon image of a checklist being checked off


Slide 42

What are effective practices for teaching a very young child to use a device?


Slide 43, Principles for Instruction

Determine a good child-device match

“Getting to know my device” period

Safety rules (emphasis on what TO do)

Experimentation phase (free flowing)

Guidance in effective use - strategies for young children

Opportunities to contact obstacles / environmental features

Parent/staff input & involvement
