  • lack of sitting after 6 months being the most common initially recognized deficit
  • Poor head control may be recognized earlier in the more involved child
  • Delayed ambulation – after 16 – 18 months in a child that is mildly involved
  • Motor delay – poor prognostic indicator
  • Abnormal motor characteristics (quality of movement) – often mistaken as “early milestones”
  • “rolling” at 2 months by opisthotonic posturing,
  • “handedness” at less than 1 year in hemiplegics,
  • “walking” at 4 months by reflex steppage.
  • W-sitting and sacral sitting with posterior pelvic tilt due to hamstring spasticity
  • bunny hop crawling

Q
  • The clinical type of CP is important
  • All children with hemiplegia will walk as will most with true ataxia, while those with atonia usually will not.
  • if independent sitting occurs by 2 years, prognosis for ambulation is good
  • ability to crawl on hands and knees by 1.5 to 2.5 years was a good prognostic sign
  • Persistence of three or more primitive reflexes at 18 to 24 months is a poor prognostic sign
  • Combinations of independent ambulation and use of wheeled mobility for greater distances should be introduced.
  • Marginal ambulators during childhood may lose functional ambulation during or after adolescence due to:
    ;progressive orthopedic deformity
    ;insufficient muscle power and
    ;Insufficient apacity to accommodate increased height
    ;weight and social/emotional problems

  • Those with pure dyskinesia as a rule are the brightest, while those with atonia and quadriplegia are most involved.
  • Retardation is usually mild in those with diplegia and hemiplegia and may be confused with learning disabilities. Seizures
  • up to 35% to 40% of children with CP
  • most common in postnatal CP, and about 60% to 70% of those with hemiplegia and quadriplegia
  • CT SCAN, MRI and EEG
  • Anticonvulsant management
  • Abnormal vision is seen in 50% of children with CP.
  • Muscle imbalances cause esotropia, exotropia, or hyperopia and are most frequent in diplegia and quadriplegia
  • Homonymous hemianopsia can be seen in hemiplegia.
  • Paralysis of upward gaze is seen in pure dyskinesia.
  • Nystagmus is seen in ataxia.
  • Defective tracking can be seen in all types of CP
  • HEARING LOSS - may be conductive due to abnormal - Eustachian tube function
  • DENTAL PROBLEMS – malocclusions, enamel dysplasias secondary to palatal distortions and abnormal oromotor reflexes, dental caries
  • Increased risk of respiratory infections is due to both extrinsic (abnormally high tone and poor control over chest muscles leading to poor sigh and cough mechanisms) and intrinsic (bronchopulmonary dysplasia) reasons.
  • Malnutrition
  • Abnormal oral motor function – increase risk of aspiration
  • Disordered GI motility with reflux proximally and poor transit time distally is seen
  • A “neurogenic” bladder can occur in the face of normal sensation

A

INTRATHECAL- CP

20
Q
  • Botulinum Toxin-A acts by irreversibly blocking presynaptic release of acetylcholine (ACh) at neuromuscular junctions (NMJs)

  • Bony - consist of either joint fusions (ankle or spine), (de)-rotations (of the femur or tibia), or angulations (of the femur).
  • The current trend is for multilevel soft-tissue surgery (rectus transfer, hamstring lengthening, and tendoachilles lengthening, TAL) and bilateral bony surgery (bilateral femoral varus osteotomies) to avoid imbalances and asymmetries
  • Selective posterior (or dorsal) rhizotomy (SPR, SDR) involves sectioning a variable percentage of sensory nerve rootlets after L2-S1 laminectomy.

38
Q

o DIAGNOSIS

  • Elevated Serum Creatine Kinase
  • A “myopathic” EMG (BSAPPs, early recruitment) is seen.
  • EKG shows cardiomyopathy with tall R-waves in the right precordial leads and deep Q-waves in the limb and precordial leads.
  • Biopsy shows variation in fiber size, fiber splitting, central nuclei, fibrous/fatty replacement, and absence of type 2B fibers.
  • abnormal genetic locus is at the Xp21 site, resulting in deficient or abnormal muscle protein, Dystrophin
  • Therapeutically, ongoing drug trials continue. - Currently, both prednisone as well as androgenic steroids are used
  • ambulation typically lost by 8 to 12 years of age.
  • Ambulation can be prolonged by bracing and/or timely surgical intervention to release contractures

SURGICAL INTERVENTION - DMD

  • resection of the iliotibial band, TAL with or without posterior tibialis lengthening or release - can prolong ambulation an average of 2 years if done prior to initial entry into the wheelchair
  • Early remobilization is vital and only minimal orthotic support is needed.

  • The clinical course is protracted compared to Duchenne, with ambulation maintained into the 20s and survival to the 40s
A

BECKER MUSCULAR DYSTROPHY

40
Q
  • The mechanism of injury is traction to the brachial plexus.
  • Most frequent is a neuropraxic injury from which more than 90% will recover fully.
  • Axonal damage, rupture of the nerve, or nerve root avulsions result in variable residual damage.
o RISK FACTORS
- primiparous mothers
- prolonged labor
- birthweight more than 8.5 lbs
- shoulder dystocia (present in >50%), 
- traumatic delivery with mid to high forceps
breech presentation. 

CLASSIFICATION
- Erb’s palsy
= involving the upper plexus (C5-7) accounts for about 80% of injuries. - “waiter’s tip” posture of shoulder internal rotation and adduction, elbow extension and pronation, wrist flexion and thumb in palm (due to loss of extensor pollicis)
- Total plexus injuries accounting for 15%.

  • Klumpke’s palsy
    = involving the lower plexus (C7, C8, T1) exclusively is now felt to be quite rare – 5%
    shoulder external rotation (abduction usually not seen due to gravity), elbow flexion and supination, wrist extension, and the intrinsic minus hand deformity
  • IN ALL TYPES: Muscle stretch reflexes are often lost. - Sensory deficits, often present

DIAGNOSIS

  • MRI has shown pseudomeningoceles in both severe and mildly involved patients and may be unreliable.
  • Early electrodiagnostic testing may distinguish neuropraxic from axonal injury and hence may define severity- as early as three weeks

TREATMENT
- FIRST WEEK - Gentle range of motion as well as pinning the end of a long sleeve shirt to the diaper waist to avoid stretching of the shoulder capsule
more aggressive range of motion should include shoulder abduction with scapular stabilization to stretch scapulohumeral adhesions, elbow supination as well as extension, and thumb abduction.
- Prone propping and wheelbarrel walking strengthen the shoulder girdle, while eliciting righting reactions can strengthen deltoid, triceps, and wrist extensors

SURGERY
- optimum age for surgery is less than 9 months
since nerve growth factor is at a maximum before 1 year of age, and there is less nerve scarring and distal muscle atrophy at that age.
- Candidates for surgery have 0 to 1/5 strength in the biceps at 3 to 4 months or have plateaued at 2/5 for 4 months
-Procedures performed include surgical neurolysis of scars, endto-end anastomosis with microsurgical fascicular repair, and cable graft of nerve rupture.

PROGNOSIS

  • Complete recovery occurs in more than 65% of children, while mild and moderate deficits are seen in 10% each.
  • 15% will have severe residual deficits.
  • Poor grade elbow flexion with 0 to trace strength in wrist and finger extensors at 6 months old may be predictive of a poor outcome
