Chapter 3 Module 2 🧠 Module Overview 🦽 Section 1: Physical Disabilities

  

What are physical disabilities?

 

Physical disabilities are conditions that can affect:

 

movement

strength

coordination

balance

physical functioning

stamina

mobility

activities of daily living

 

They may be:

 

Congenital — present from birth

Acquired — developing later because of illness, injury, or another condition

 

The effects vary greatly between individuals. Two people with the same diagnosis may have very different levels of mobility, independence, communication, and support needs.

 

C — Cerebral Palsy

 

Cerebral palsy (CP) is a group of neurological conditions affecting movement and posture. It results from disturbances in the developing brain and can affect movement, coordination, muscle tone, communication, vision, and other functions.

 

One of the most important points when discussing CP is:

 

Physical or speech difficulties should never be assumed to indicate intellectual disability.

 

A person with severe physical impairment, dysarthria, or little or no spoken communication may have intact cognitive abilities. Communication barriers can sometimes cause other people to underestimate the person's intelligence.

 

🧠 CP and Cognition

 

Cerebral palsy does not automatically cause cognitive impairment.

 

Cognitive abilities depend partly on the underlying brain injury or developmental difference. Some people with CP have average or above-average intellectual abilities, while others may have intellectual or specific cognitive difficulties.

 

Possible areas of difficulty can include:

 

visual-spatial processing

processing speed

attention

working memory

executive functioning

organisation

task switching

 

These difficulties should be assessed rather than assumed.

 

Co-occurring conditions such as epilepsy, visual impairment, or hearing loss can also affect learning and communication and therefore need to be considered when assessing someone's abilities.

 

Presuming Competence

 

A crucial principle is presuming competence.

 

Someone who cannot speak clearly, cannot write conventionally, or has significant physical limitations may still understand far more than they can physically communicate.

 

Augmentative and Alternative Communication (AAC) can provide alternative ways of expressing:

 

thoughts

choices

needs

feelings

knowledge

opinions

 

This is particularly important when assessing cognitive ability because the assessment should not confuse difficulty communicating a response with not knowing the answer.

 

Types of Cerebral Palsy by Movement Pattern

1. Spastic CP

 

Spastic CP is the most common type and involves increased muscle tone (spasticity).

 

Muscles can become stiff, and movements may appear awkward or restricted.

 

Possible effects include:

 

difficulty walking

tightness in the legs

toe walking

reduced range of movement

difficulties with fine motor control

dysarthria affecting speech

 

A scissoring gait can occur in some people when increased tone causes the legs to move inward and cross.

 

2. Dyskinetic CP

 

Dyskinetic CP involves involuntary movements and abnormal muscle tone.

 

Movement may include:

 

dystonia — sustained or intermittent muscle contractions causing twisting or unusual postures

choreoathetoid movements — involuntary, uncontrolled movements

 

These movements can make:

 

walking

sitting

reaching

eating

writing

speaking

 

more difficult.

 

Speech can be significantly affected because speech requires very precise control of many muscles.

 

However, difficulty producing speech does not necessarily mean difficulty understanding language. AAC can therefore be extremely valuable for some individuals.

 

3. Ataxic CP

 

Ataxic CP primarily affects coordination and balance.

 

Possible features include:

 

unsteady walking

a wide-based gait

difficulty judging distance

tremor

difficulties with precise movements

 

Speech may also be affected, producing ataxic dysarthria, in which speech can sound irregular in timing, rhythm, or emphasis.

 

4. Mixed CP

 

Some people have characteristics of more than one movement pattern.

 

For example, spastic-dyskinetic CP combines features of spasticity and dyskinetic movement.

 

🧍 Classification by Distribution of the Body

 

The distribution of motor impairment can also be described using terms such as:

 

Pattern     Main areas affected

Monoplegia     One limb

Hemiplegia     One side of the body

Diplegia    Both legs are affected more than the arms

Quadriplegia  All four limbs, trunk, and often other muscle groups are significantly affected

 

These terms describe motor distribution, not intelligence.

 

Walking ability varies considerably within each group. For example, many people with hemiplegia walk independently, while some people with diplegia may use mobility aids.

 

🚶 GMFCS

 

The Gross Motor Function Classification System (GMFCS) is used to classify gross motor function in children and young people with cerebral palsy.

 

It has five levels:

 

Level I: Walks without significant limitations but may have some difficulty with advanced motor activities.

Level II: Walks without a mobility device but has greater difficulty with uneven surfaces, inclines, crowds, or longer distances.

Level III: Usually walks with a hand-held mobility device and may use wheeled mobility for longer distances.

Level IV: Has significant limitations in self-mobility and commonly uses powered mobility or requires substantial assistance.

Level V: Has severe limitations in voluntary movement, head and trunk control, and requires extensive assistance and supportive equipment.

 

The GMFCS describes gross motor functioning. It does not measure intelligence, communication ability, or overall quality of life.

 

🦴 S — Spina Bifida

 

Spina bifida is a congenital neural tube defect that occurs when the neural tube does not close completely during early embryonic development.

 

The neural tube develops into the brain and spinal cord. Neural tube closure occurs very early in pregnancy, generally during the first four weeks after conception.

 

The effects of spina bifida vary considerably depending on the type and location of the defect.

 

Primary Types of Spina Bifida

Type   General description

Spina bifida occulta  The mildest form; there is a small defect in the vertebrae, often without an obvious opening or major neurological impairment.

Meningocele   The protective membranes around the spinal cord protrude through an opening in the spine. Neurological effects can vary.

Myelomeningocele     The most severe common form; the spinal cord and its surrounding membranes protrude through the spinal opening, often resulting in significant neurological impairment.

 

Possible effects of more significant spina bifida can include:

 

weakness or paralysis of the legs

reduced sensation

mobility difficulties

problems with bladder or bowel function

hydrocephalus

difficulties with coordination

orthopaedic complications

 

Again, the diagnosis alone does not tell us exactly what an individual can or cannot do. Support needs depend on the person's particular neurological and physical effects.

 

   Incomplete Tube Closure ──► Spina Bifida

Neural Tube Formation: In the first four weeks of gestation, a special layer of embryonic cells rolls into a tube shape to lay the foundation for the central nervous system.

 

Incomplete Closure: If the tube fails to seal shut along the spine, an opening remains. This can leave vulnerable spinal nerves unprotected or protruding outside the vertebral column, causing neurological damage.

 

Primary Types of Spina Bifida

Type   Severity   Description

Spina Bifida Occulta Mildest     Small gap in the spine, but covered by skin. Often symptomless ("hidden") and discovered incidentally.

Meningocele   Moderate The protective fluid-filled sacs (meninges) push through the spinal opening, but the spinal cord itself remains in place.

Myelomeningocele     Most Severe  The spinal cord and nerve roots protrude through the back opening, creating a high risk of nerve damage and severe complications.

Key Risk Factors

Nutritional Deficiencies: Inadequate maternal intake of folic acid (Vitamin B9) before and during early pregnancy is one of the strongest modifiable risk factors.

 

Genetics: A family history of neural tube defects increases the probability of recurrence in future pregnancies.

Spinal Cord Injury – paralysis or loss of function. The key principle is especially important

 

Never assume a person's cognitive ability from their physical appearance, movement, speech, or method of communication.

 

Someone may have severe motor impairment, dysarthria, or little/no spoken language while having strong intellectual abilities. Conversely, some people with physical disabilities may also have intellectual, cognitive, or learning difficulties.

 

Therefore, individual assessment and accessible communication are essential.

 

This principle applies particularly well to cerebral palsy and spina bifida, where physical and communication difficulties can sometimes obscure a person's actual cognitive abilities.

 

🧠 Physical and Psychological Disabilities

 

A good overall definition for your module is:

 

Physical disabilities primarily affect physical functioning, such as movement, strength, coordination, mobility, or stamina. Psychological disabilities primarily affect psychological functioning, such as emotions, thoughts, behaviour, or perception. However, the two can interact, and some conditions can affect both physical and psychological functioning.

 

Examples

Physical    Psychological

Cerebral palsy     Depression

Spina bifida   Anxiety disorders

Multiple sclerosis Bipolar disorder

Muscular dystrophy  PTSD

Spinal cord injury     Schizophrenia

 

The biopsychosocial model is useful here because a person's experience can involve biological, psychological, and social factors simultaneously.

 

For example:

 

Physical disability

↓

Pain, fatigue, mobility barriers, accessibility problems

↓

Possible social isolation or reduced participation

↓

Possible psychological effects such as frustration, anxiety, or low mood

 

But the relationship can work in the other direction too:

 

Psychological difficulties

↓

Problems with sleep, concentration, motivation, or activity

↓

Possible effects on physical functioning and daily routines

 

These are possible relationships, not inevitable outcomes.

 

🦽 Cerebral Palsy — Important Nuances

 

Your CP section is particularly useful because it reinforces the presuming competence principle.

 

What I would change

 

I would avoid saying:

 

“The specific brain region injured determines how tone and movement are disrupted.”

 

That's a little too definite. Cerebral palsy results from disturbances to the developing brain, and the relationship between the underlying neurological injury and the resulting movement pattern is more complicated than identifying one specific brain region.

 

Similarly, statements such as:

 

“Damage limited strictly to the motor cortex... may leave cognitive functions completely intact”

 

are possible, but they shouldn't imply that clinicians can reliably determine someone's cognition simply from the presumed location of the brain injury.

 

A safer formulation is:

 

The neurological injury associated with CP can vary considerably. Some people have primarily motor difficulties, while others may also experience differences in cognition, attention, visual processing, executive functioning, communication, or other areas.

 

Classification by Movement Pattern

 

Your four categories are useful:

 

Spastic CP

 

Characterised by increased muscle tone and stiffness.

 

Possible effects include:

 

stiff or restricted movement

difficulty walking

toe walking

scissoring gait

fine-motor difficulties

dysarthria in some individuals

Dyskinetic CP

 

Involves involuntary movements and abnormal or fluctuating muscle tone.

 

This can include:

 

dystonia

involuntary movements

unusual postures

difficulties controlling movement

speech difficulties

swallowing difficulties

 

Importantly:

 

Difficulty producing speech does not automatically mean difficulty understanding speech.

 

AAC can therefore be extremely important.

 

Ataxic CP

 

Primarily involves difficulties with:

 

balance

coordination

precision

depth and distance judgement

 

Speech can also be affected through ataxic dysarthria.

 

Mixed CP

 

Some individuals have characteristics of more than one movement type.

 

🚶 GMFCS

 

Your inclusion of the Gross Motor Function Classification System (GMFCS) is useful.

 

The major point to remember is:

 

GMFCS measures gross motor function; it does not measure intelligence.

 

The five levels range from:

 

Level I → walks without significant limitations

Level II → walks but has greater environmental/mobility difficulties

Level III → walks with a hand-held mobility device and commonly uses wheeled mobility for longer distances

Level IV → significantly limited self-mobility; powered mobility may be used

Level V → severe limitations in voluntary movement and head/trunk control, requiring extensive assistance

 

So a person could have GMFCS Level V and still have significant intellectual strengths.

 

That is exactly why the presuming competence principle matters.

 

🦴 Spina Bifida

 

Your explanation of spina bifida is broadly good.

 

The most important correction is:

 

Spina bifida is a neural tube defect, rather than simply a “spinal cord development condition.”

 

The neural tube forms the foundations of the brain and spinal cord. Failure of complete closure very early in embryonic development can result in a neural tube defect such as spina bifida.

 

Main forms

Type   General description

Spina bifida occulta  A small vertebral defect covered by skin; often has few or no symptoms

Meningocele   The meninges protrude through the spinal opening while the spinal cord remains in its usual position

Myelomeningocele     The spinal cord and meninges protrude through the opening and neurological impairment is usually more significant

 

The effects of myelomeningocele can include:

 

mobility difficulties

weakness or paralysis

sensory differences

bladder and bowel difficulties

orthopaedic problems

hydrocephalus

possible cognitive or learning differences

Cognitive and learning differences

 

This section of your notes is particularly valuable because it shows that physical disability and cognitive functioning cannot simply be predicted from one another.

 

Some people with spina bifida, particularly those with myelomeningocele and associated hydrocephalus, may experience difficulties with:

 

attention

processing speed

working memory

executive functioning

planning and organisation

visual-spatial processing

problem-solving

social information processing

 

At the same time, basic language and vocabulary can be relatively strong.

 

So someone may sound extremely articulate while still having difficulties with comprehension, organisation, attention, or applying information.

 

Again:

 

Fluent speech does not necessarily mean complete comprehension.

 

And:

 

Limited speech does not necessarily mean limited understanding.

 

🛠️ Assistive Technology vs Disability

 

I agree with separating these in your notes.

 

A wheelchair is not a disability.

 

It is assistive technology/equipment that can help a person with a mobility disability move around and participate more independently.

 

The same applies to:

 

walkers

crutches

orthoses

communication devices

AAC systems

adapted computer equipment

 

This is an important strengths-based perspective because assistive technology can increase independence rather than represent dependence.

 

🌟 The central message of Module 2

 

I think this is the strongest way to bring the whole section together:

 

A diagnosis does not tell us everything about a person's abilities.

 

Two people with cerebral palsy can have very different movement, communication, cognitive, emotional, and support needs. The same is true for people with spina bifida and many other disabilities.

 

Therefore, good care involves:

 

Understand the condition

↓

Assess the individual

↓

Identify strengths and barriers

↓

Provide accessible communication and appropriate support

↓

Make reasonable adjustments

↓

Promote independence, participation, dignity, and choice

 

That also creates a very natural link back to your previous strengths-based support section: we support the person, not simply the diagnosis.
