Neuromuscular Assessment 2 Flashcards
What is CP?
Permanent but changeable
Caused by non progressive defect or lesion in 1 or multiple locations
Utero/during or shortly after birth
Infectious meningitis and trauma are the most common causes of acquired CP
Produces motor and possible sensory deficits
Involves 1 or more limbs and usually the trunk
Voluntary motor function deficits
Produces multiple symptoms
Anatomic sites of involvement, degree of disability, associated dysfunction and causes are heterogeneous
What are some common problems seen in children who have Cerebral Palsy
Learning disabilities in 50-70 percent
Speech disorders in 25 percetn
Auditory in 25 percent
Seizure disorders in 25 -35
Disc dengeration and cervical spine instability
Visual disturbances in 40-50%
Strabismus, esotropia, nystagmus, homonymous hemianopsia
How is CP classified?
Area of the body exhibiting impairments
Movement abnormalities resulting from brain lesions
Degree of severity of CP
Area of Body impairment Classification system
Monoplegia- involvement of one limb
Diplegia (paraplegia)- involvement in both lower limbs
Hemiplegia- upper and lower limbs on one side
Quadriplegia- equal involvement in all limbs
Molnar (85), identifies several major groups of children with CP based upon clinical signs
(4) main clinical sgins
. 1. Spastic- motor cortex hemiparesis, diplegia, quadriplegia 2. Dyskinetic- basal ganglia athetosis,(slow writhing finger movements of the the lower extermity) dystonia, choreiform movements, ballismus, tremor 3. Ataxia- cerebellar lesion 4. Atonia, hypotonic
what does spastic mean?????
showing upper motor neuron involvement (hyperreflexia, abnormal movement patterns, weakness, loss of dexterity) -motor cortex
What is athetosis
Dystonia, Choreiform, Ballisums,
Athetosis- showing signs of extrapyramidal involvement with involuntary movements slow writhing movements of face and extremities
Dystonia -rhythmic, changing tone proximally leading to slow uncontrolled movements with a tendency towards fixed postures -basal ganglia
Choreiform movements- rapid jerky movements of face and extremities
Ballismus – coarse flinging movements of extremities with wide amplitude of motion
Tremor – fine shaking of head and extremities
Rarer types of CP what does Hypotonic come from
Ataxic-
Can you have mixed types of lesions yes or no
Hypotonic- showing severe depression of motor function and weakness
Ataxic- showing signs of cerebellar involvement with ataxia (rare) -cerebellar lesion
Mixed lesions combine characteristics of spastic, athetoid and ataxic groups
Describe some characteristics of hypotonic CP think decreased muscle tone.
\Flaccidity
Extreme floppiness
Inability to generate muscle force
Transient- reclassified spasticity or athetosis
Describe some characteristics of Spascity CP
Dystonia
Resistance to passive stretch
Hyperactive stretch reflexes (hyperreflexia)
Changes in muscle structure & function
Abnormal muscle activity elicited by changes in head or body positions
UE flexion/ LE extension
Athetoid CP
Without a fixed steady position and may involve choreiform or writhing movements
Maintain fixed dystonic posture
Involuntary movements at rest and during movements
Joints often hyper mobile and dislocations occur especially if spasms are present
Ataxic CP (just think lack inability to vounlantary control muscles)
Uncommon
Hydrocephalus, head injury, encephalitis, or cerebellar tumor
Difficulty controlling rate, range, direction and force of movements
So thinking back to neuro where might the Brain lesion be and what might result if its
Coritcal Basal Ganglia lesion- think athen lives in the BG.
Cerebral Cortex-
Cerebellar
Cortical Basal ganglia thalamic loop- dyskinesia or athetosis, intermittent muscular tension of extremities or trunk, involuntary movement patterns
Cerebellar lesion- ataxia, general instability of movement
Cerebral cortex & pyramidal tracts- spasticity
Hypotonic classification- diminished resting muscle tone and decreased ability to generate voluntary muscle force
Give some examples of Single System Problems ( like think muscular system ) what are some malalignments from that
Expressed in muscular and skeletal systems damage occurred in the CNS Insufficient force generation Spasticity (vel dependent) tone Abnormal extensibility Exaggerated or hyperactive reflexes Malalignments (femoral anteversion/ femoral & tibial torsion)
Multisystem Approach think like
Expressed in the Neuromuscular system
Poor selective control of muscles
Poor regulation of activity in muscle groups in anticipation of postural changes
Decreased ability to learn unique movements
