1 Walks without Restrictions: limitations are present in more advanced motor skills

2 Walks without Assistive Devices: limitations are present in walking outdoors and in the community

3 Walks with Assistive Mobility Devices: limitations are present in walking outdoors and in the community

4 Self Mobility With Limitations: children are transported or use power mobility outdoors and in the community (are usually joystick drivers)

5 Self Mobility is Severely Limited: even with use of assistive technology (may be joystick or alternate access drivers)Palisano,R. et al. Developmental Medicine and Child Neurology 1997; 39: 214-223

Importance of independent mobility

Self-produced locomotion plays a crucial role in cognitive and psychosocial development

Limited mobility has a negative impact on development

Able bodied children in orphanages deprived of normal opportunities to move (Dennis, 1973)

Tatlow (1980) found children with disabilities who could not move independently were passive and had vague body awareness

Independent mobility makes kids smarter

Campos and Bertenthal (1987) believe that independent locomotion facilitates psychological change

Locomotor experience is linked to self-awareness, emotional attachment, spatial orientation, fear of heights and visual/vestibular integration (Kermoian, 1997)

Butler C., Okamoto G.A., & McKay T.M. (1983). Powered mobility for very young disabled children. Developmental Medicine and Child Neurology. 25, 472-474.

9 motor disabled children aged 20 – 39 months

Motorized chair at home over a 7 week period

8 children were able to drive safely and independently

Stimulated social emotional and intellectual behaviour

Butler C., Okamoto G.A. & McKay T.M. (1984). Motorized wheelchair driving by disabled children. Archives of Physical Medicine and Rehabilitation. 65, 95-97.

13 children with physical disabilities aged 20 to 37 months.

12 children learned to drive the chair competently in an average of 16 days.

Able to drive without bumping doorways or corridors and stop without hitting obstacles in less than five days

Conclusion: Children as young as 24 months can learn

to drive a power chair

Butler C. (1986). Effects of powered mobility on self-initiated behaviors of very young children with locomotor disability. Developmental Medicine and Child Neurology, 28, 325-332.

Multiple baseline design 6 children with physical disabilities aged

23-38 months Used chair for less than three weeks Conclusion:

Most increased frequency of interaction with objects

Increased spatial exploration Affected communication with caregiver

12 physically disabled preschoolers aged 2.5 – 5 years

Electrical go-kart for 1 year

Caregivers and Therapists reported positive effects on emotional, intellectual and motor development

And yet… Ontario study (Palisano et al, 2003) of 636

children with CP only 24% of children at GMFCS level IV and 3%

of children in Level V used powered mobility UK report (Staincliffe, 2003)

10% of services exclude under 5’s 46% of services are never referred under 5’s 46% more services offered indoor/outdoor

chairs to over 5’s than under 5’s

Opportunities for mobility

Children with disabilities should be provided with the same opportunities as other children (and at the same age) to move independently and to explore their environment

Options: Supportive walkers/gait trainers Adapted tricycles Powered mobility

Myths

Using a power chair will prevent a child from walkingA child who has any potential to propel a manual chair or to walk should be encouraged to do so as much as possible


Motor skills did not decline in either the experimental or control group

Bottos M. and Gericke C. (2003). Ambulatory capacity in cerebral palsy: prognostic criteria and consequences for intervention. Developmental Medicine & Child Neurology. 45, 786-790.

1. Children who cannot sit independently and crawl or bunny hop by age 3 are unlikely to walk

2. Those who have achieved these milestones by age 3 will likely walk by age 7 but many will lose the ability to walk in the future

3. Those who walk by age 3 will maintain walking longest, but may still lose ability to walk due to physiological burnout

How do you decide whether a child is ready for powered mobility?

1. Cognitive readiness tests

2. Formal driving tests3. Provide practise

opportunities and evaluate in natural setting

4. Practise with switches and joystick on computer

Myth

Children need certain cognitive and prerequisite skills before being ready to try powered mobility

Furumasu J., Guerette P. and Tefft D. (2004). Relevance of the pediatric powered wheelchair screening test for children with Cerebral Palsy. Developmental Medicine & Child Neurology. 46, 468-474.

26 children with CP (aged 2-6 years) Assessments:

Pediatric Powered Wheelchair Screening Test (PPWST)

Symbolic Representational Scale (SRS) Coping Inventory

6 wheelchair training sessions – final session assessed using Power Mobility Program (wheelchair driving test)

Results PPWST predictive for children with CP

who were able to use joysticks SRS marginally increased predictive

power for this group only. Children should be beyond the object

level in order to drive functionally PPWST was not predictive for children

with CP who used switch controls

Bottos M et al. (2001). Powered wheelchairs and independence in young children with tetraplegia. Developmental Medicine and Child Neurology. 43, 469-477.

Would you use powered mobility with a child who doesn’t have established cause & effect?

1. Yes2. No

Myth

Children need to demonstrate understanding of cause-effect with toys and computers before being introduced to powered mobility

Nilsson L. and Nyberg P.J. (1999). Single-switch control versus powered wheelchair for training cause-effect relationships: case studies. Technology and Disability. 11, 35-38.

Case study - 1yr old girl

Drove with intent at 2 ½ years and understood use of switch toys.

Drove functionally at 3 ½ years but

did not understand use of computer mouse until age 4 ½.

Nilsson and Nyberg (1999) cont.

40 individuals aged 1-50 functioning at an early developmental level

9 could drive a powered chair but only 2 could use a computer mouse.

14 enjoyed switch toys but only 5 could wait for response from toy before hitting switch again.

Nilsson and Nyberg (1999) cont.

17 infants (typically developing) followed from 3-12 months

At 3-4 months infants understood cause-effect with joystick.

At 7-8 months they understood direction in chair and used switch toys.

At 12 months they still had no interest in computer mouse.

Nilsson’s suggested Developmental Progression

Early cause-effect in powered chair Beginning directional control and

cause-effect with separate switch and toy

Functional Driving Computer mouse use

Myths

Children with multiple and complex disabilities are not able to use power wheelchairs

Children with sensory disabilities can’t use power mobility

Qualitative study 13 children with a wide spectrum of

physical, cognitive and sensory issues. 3 educational settings. Smart Wheelchair for one school year Progress was measured using IEP goals Computer analysis of interaction

Smart Wheelchair

Results Safe learning environment Promoted broad developmental

changes e.g. cause-effect, motivation, initiation, assertiveness and persistence

Some children transitioned to standard powered chair

What do you think are the greatest barriers for families when beginning to talk about powered mobility?

1. Emotions (i.e. giving up on walking or fear of losing strength)

2. Attitudes (i.e. viewing the child as looking more disabled)

3. Barriers with environment or transportation

4. Funding

Qualitative study - interviewed 5 mothers of children who were using power mobility

Negative feelings towards first wheelchair Power mobility seen as a last resort Positive feelings as child experiences

increased independence and control Environmental barriers Enables meaningful engagement Positive effect on others attitudes

What is your approach to powered mobility training?

1. Informal – let child use chair in daily life

2. Formal training - following directions, obstacle courses etc

3. Safe environment – play based learning

Durkin J (2005). Developing powered mobility with children who have multiple and complex disabilities: Moving forward. Doctoral dissertation. University of Brighton.

Qualitative study – grounded theory Aim – to identify components and

development of how children learn to use powered mobility

Observation of 11 typical children – 6 months -5 years

Observation of 11 children with disabilities Focus group with 7 children who used

powered mobility Focus groups with 22 peer professionals

Recommendations

Safe learning environment Child-led approach Adult as a ‘responsive partner’ Beginning learners are distracted

by and cannot attend to adult verbal instruction


Children with complex difficulties take longer to learn to use the power chair

More intense training may be helpful in a structured controlled environment for initial skill acquisition.

Blocked trials are better for initial learning but random practise is better for skill retention

Odor P. and Watson M. (1994). Learning through Smart Wheelchairs: A Formative Evaluation of the effective use of the CALL Centre’s Smart Wheelchairs as past of children’s emerging mobility, communication, education and personal development. http://callcentre.education.ed.ac.uk

Most successful when child had opportunity for structured and unstructured use throughout the day

Less successful outcomes related more to lack of opportunity due to poor environmental support and integration than a difference in the child’s abilities

Nilsson LM and Eklund M (2006). Driving to learn: Powered wheelchair training for those with cognitive disabilities. International Journal of Therapy and Rehabilitation. 13, 517-527.

45 people with profound multiple and cognitive disabilities

Age 12 months – 52 years Video recordings Aim – to identify indicators of

factors that facilitated or hindered learning joystick use in the powered chair

Recommendations Chair needs to have immediate

response when the joystick is moved Midline joystick position Chair needs to have low speed, low

power and respond the same way in all directions

Use of safety stop switches, bumpers and line followers can interfere with learning

Expectations

Exploratory drivers

Supervised drivers

Independent drivers

Implications for practice

Use of a powered mobility device can enhance psychosocial development and independence in young children with CP


Using powered mobility at a young age will not impede development of independent ambulation or other motor skills

Implications for practice Children with CP who

have a poor prognosis for independent ambulation (GMFCS Levels IV and V) require assisted mobility opportunities at the same age as their typical peers in order to promote overall development.


IQ and cognitive readiness tests do not predict which children with CP will become functional power chair users

Implications for practice Children with CP

may need more time and training than other children learning to use powered mobility. Potential cannot be determined based on a short term trial

Implications for practice Young children

may learn to use switches and joysticks in a powered mobility device more easily than with toys and computers.


Initial training for powered mobility in therapy sessions is helpful before the child is ready to use a power chair in daily life

Children need time to play and explore on their own and may be distracted by adult direction

Mixture of structured and unstructured training


Time and environmental support are very important
