MOD 5: Motor Functioning Flashcards
What are the 3 different types of disabilities associated with motor functioning
- Congenital (present at or before birth):
Examples: Cerebral palsy, spina bifida, muscular dystrophy.
- Acquired (present after birth):
Examples: Spinal cord injury, multiple sclerosis, osteoarthritis, rheumatoid arthritis, fibromyalgia.
- Amputation: Loss of a limb or body part impacting motor function.
What are the key differences between individuals with congenital vs acquired motor functioning disabilities in terms of physical and psychological factors?
Physical Factors:
Acquired: Individuals may have higher muscle tone and prior physical activity experience, making it easier to regain strength.
Congenital: Likely have lower baseline physical activity levels, making it harder to develop physical skills and strength.
Psychological Factors:
Acquired: May struggle more with rejoining activities, feel loneliness, and compare current performance to pre-injury abilities.
Congenital: Likely more familiar with resources and support systems, as they’ve had access since birth, while those with acquired disabilities may be less aware of available resources.
Access to Resources:
Congenital: Often have long-term rehabilitation teams and access to resources from an early age.
Acquired: May face challenges accessing resources, especially if the disability is acquired in young adulthood (ages 18-21) when pediatric services are no longer available.
What is cerebral palsy (CP), and what causes it?
Cerebral palsy is a group of permanent disorders affecting movement and posture, causing activity limitations. It is caused by non-progressive disturbances in the developing fetal brain.
What are some common comorbidities associated with cerebral palsy beyond motor dysfunction?
Cerebral palsy is often accompanied by sensory, perceptual, cognitive, communication, and behavioral disturbances, as well as epilepsy and secondary musculoskeletal problems.
how does CP affect males vs females
equally
cause of CP
Cerebral palsy (CP) results from a series of causal pathways, meaning that there is not one single cause, but rather a combination of factors that lead to the brain disturbances responsible for the condition.
symptoms of CP
- Muscle tightness or spasticity
- Involuntary movement
Disturbance in gross motor skills - Difficulty with fine motor skills
- Difficulty in swallowing and problems with speech
- Abnormal perception and sensation
What are the 3 classifications of CP?
- Topographical
- Neuromotor
- Functional
what is the topographical classification of CP comprised of?
categorizes based on what limbs are affected, and how severely
Plegia=paralysis
Paresis= weakened
Quadriplegia: all 4 limbs paralyzed
Diplegia: all 4 limbs involved, both legs more severely affected than arms(legs paralyzed, arms weakened)
Hemiplegia: one side of body is affected, arm usually more impacted(paralyzed) than leg
Triplegia: 3 limbs involved,usually both arms and leg
Monoplegia: only one limb is affected, usually an arm
what is affected by a quadriplegic topographical classification ?
all 4 limbs are paralyzed
(plegia=paralysis)
what is affected by a diplegia topographical classification ?
all 4 limbs involved, both legs more severely affected than arms(legs paralyzed, arms weakened)
what is affected by hemiplegia topographical classification ?
one side of body is affected, arm usually more impacted(paralyzed) than leg
what is affected by triplegia topographical classification ?
3 limbs paralyzed,usually both arms and leg
what is affected by monoplegia topographical classification ?
only one limb is paralyzed , usually an arm
What is the neuromotor classification of CP?
Spastic
- increased muscle tone (hypertonia), causing stiff and jerky movements.
- Increased muscle tone
Stiff limbs
non spastic
- hypotonia
- decreased or fluctuating muscle tone, leading to more involuntary and uncontrolled movements.
- Decreased muscle tone
Loose, floppy limbs
What is Spastic (Pyramidal) Cerebral Palsy, and how common is it?
Spastic CP is the most common type, accounting for about 80% of cases.
- involves hypertonia, causing jerky movements and hyperactive stretch reflexes, primarily affecting the flexors and internal rotators.
What part of the brain is affected in Spastic (Pyramidal) Cerebral Palsy?
- motor cortex and the pyramidal tract
- leading to hypertonic muscle responses and motor control issues.
What are the common symptoms of Spastic (Pyramidal) Cerebral Palsy?
Hypertonic muscles
Jerky movements
Intellectual disability, seizures, and perceptual disorders
Mild to severe spasms
Contractures and bone deformities due to flexors and internal rotators being primarily affected.
what is spastic diplegia characterized by
hyper motor issues (jerky movements, spams) primarily in both legs
what is the prevalence of non spastic CP, and what are the subtypes
20% of all CP cases
Athetoid(Dyskinetic)(15%)
Ataxia ~ 5% of non-spastic CP cases
What areas of the brain are affected in Non-Spastic (Extrapyramidal) Cerebral Palsy?
- basal ganglia or cerebellum
-causing difficulties with movement coordination and control.
How does Non-Spastic CP affect muscle tone and movement?
Difficulties in controlling and coordinating movement
* Ability to speak impacted by physical (not intellectual) impairment
* Weakened and unstable muscle tone (hypotonic) + jerky movements
* Slow or fast, often repetitive, and rhythmic
* Involuntary movements (sleep ceases movements; anxiety/stress worsen movements)
* Skills involving coordinated movement affected (e.g., speech, reaching, grasping)
How do external factors like stress or anxiety affect individuals with Non-Spastic CP?
Involuntary movements worsen during anxiety or stress but tend to cease during sleep.
What kinds of skills are commonly affected in individuals with Non-Spastic CP?
Skills requiring coordinated movement, such as speech, reaching, and grasping, are significantly impacted due to difficulties with muscle control and coordination.
