Q

Etiology of Spina Bifida

A
  • Abnorm growth/dev. of SC or spinal column
  • MM cause unknown
  • Attributed to few factors:
    • genetics
    • teratogens→ alcohol/anticonvulsant exposure in utero
    • Nutrition deficiencies→ dec folic acid
      • daily supp 3mos prior to conception

Q

Incidence/Prevalence

A
  • .4-.9/1000 births
  • Better technology and prenatal screening==> prevents early death from birth trauma to neural sac
  • Perinatal mgmt:
    • option to terminate, better options thru c-section, repair in-utero of neural sac

Q

Spina Bifida: Overview

A
  • M + S loss varies
  • Any lesion== risk for loss of function over time
  • Paralysis may not be observed until later in life:
    • abnorm tissue growth (dysplasia) == pressure on nerves
    • progress. neuro impairment via tethering of SC
      • ==> growth spurts: SC does not lengthen @ same rate

Q

MSK Deformities

Hips and Knees

A
  • Hips
    • reduce bone loading=> deforms of femoral head and acetabulum=> inc risk sublux/disloc
      • U/L disloc→ fix, B/L disloc→ leave alone
  • Knees
    • flex/ext contractures
    • varus/valgus deforms.
32
Q

MSK Deformities:

Feet

A

    • Club foot, Pes cavus/planus, Claw toe, Ankle PF contractures
  • NOTE: Sx for ankle-feet when cannot be alleviated by orthotics and when child shows desire to stand ~puberty
33
Q

Osteoporosis

A
  • Dec bone mineral density 2* hypOtonia, DEC mm strength, DEC loading→ Fx’s
  • Tx: CAREFUL W/ STRETCHING!!!
    • Incd fx risk
    • Excess/aggressive ROM avoided*
34
Q

Sensory Deficits

A
  • HIGHLY VARIABLE→ sensory lvls do not correlate to motor lvls and skip lvls may be present*
  • Consider:
    • test all derms+multiple sites w/in one derm
    • *skin inspection + pressure relief= critical
    • caution w/ modal’s
    • use of vision to aide in acts requiring incd body aware/learning new skill
      • mirrors, skin inspect
35
Q

Common brain disorder/event w/ SB

A

hydrocephalus

36
Q

Hydrocephalus

*COMMON

A
  • Excess accumulation CSF in ventricles of brain
  • 25% born w/, 60% dev. later, persists t/o lifespan
  • Cerebellar hypoplasia w/ caudal displace of hindbrain thru foramen magnum (Arnold-Chiari II Malformation) assocd w/ hydroceph.
  • usually req’s shunts→ have comps:
    • infection, malfunction→ gradual, subtle sx’s***
37
Q

Hydrocephalus + Chiari Malformations

A

see pics

38
Q

Shunts:

2 Basic Types

  2. VA→ Ventricle in brain to R. atrium of heart
39
Q

Shunts:

Major precautions

AVOID!

A

AVOID any act. that places heart/stomach above head

  • upside down, wheelbarrow walking, gymnastics
  • 1 way valve mech. may malfunction
  • avoid direct pressure to skull where shunt is
40
Q

Shunt Malfunction Red Flags

*NOTE: PT may be first to ID shunt malf.

A
  • Recurring HA***
  • Irritability***
  • changes in speech, fever, dec school perform, inc strabismus, changes app/wt, worse scoliosis, incd spasticity, decd static grip, diff waking AM, visual changes, incd SZ, dec visuoperceptual coord, “off”
41
Q

Cog/Lang Delays w/ MM and hydrocephalus:

Diffs in discourse

A
  • High freq of irrelevant utterances***
    • “Cocktail personalities”*** talk about same thing (remember Dr. Conklin’s ex of little girl!!!)
  • Delayed ability to learn, diff w/ abstract thought
  • Considerations:
    • environ changes dec stimuli, allow inc processing time, keep cues simple/functional, repetition!!!
42
Q

Latex Allergy

A

18-40% children w/ MM ***

43
Q

Spasticity and MM

A

Highly variable!!

  • HypO, normal, HypERtonia (highly variable)
  • Considerations:
    • Tone scales, observe during functional mobility and Tardieu testing, may fluctuate* (hypO one day, hypER another)
44
Q

Progressive Neuro Dysf.

Typical progression of SB:

A
  • Deterioration of motor function
  • Pain
  • Progression of MSK deformity
  • Changes in B&B functoin
45
Q

SB displays progressive neuro dysf with a typical progression (other card)

Considerations:

A
  • Tethered cord rate is HIGHER for SB pop.
    • Monitor signs→ LBP, bladder incont., diff walking, weak/numb legs or feet
46
Q

Seizures in SB

Etiologies/Considerations

A
  • Etiologies→ hydrocephalus
    • shunt or brain malf.
    • brain infection
  • Considerations:
    • Be aware of sz presentation (ask parents!)
    • Be aware sz meds which may add to cog delays/dec alertness in PT
47
Q

Neurogenic Bowel/Bladder

A

Dysf of system preventing voluntary control of voiding

  • Considerations:
    • Pts not “potty trained” on time, part of team to assist w/ cath program, mbr of team for mobility aspect of B&B program, full bladder or missed BM may impact PT
48
Q

Skin Breakdown w/ SB

A
  • 85-95% all children w/ MM by adulthood
    • pressure, poor fit orthotics, friction/shear transfers or ADLs, poor hygiene/diaper sched.
  • Considerations:
    • orthotics full contact==reduce pressure sores, education press. relieving techs, skin inspection education w/ mirror
49
Q

Obesity

A

Common in children w/ MM!

  • Complicates mobility, ADLs, orthotic wear
  • Considerations:
    • Educate fitness/health lifestyle,
    • Community programs→ swimming, cycling, adapted yoga, refer out if needed (nutritionist)
50
Q

SB Additional Findings:

Upper Limb INcoordination

A
  • Assocd w/ MM+Hydrocephalus
    • poor visuoperceptual skills, fine motor tasks impaired
51
Q

Which three?

A

CN VI- Abducens

CN IX- Glossopharyngeal

CN X- Vagus

52
Q

SB Additional Findings

CN Palsies

A
  • VI-Abducens→ Lateral rectus weakness

53
Q

PT Examination: Infancy

Muscle Function

position of choice?

A
  • Side-Lying!!! → gravity-eliminated
54
Q

PT Examination: Infancy

Muscle Function

A
  • Reliable baseline of mm function before/after back closing
    • predicts future function and monitors status/progress
    • S/L== position of choice***
    • test when alert, hungry, crying
    • only observe, not handle
55
Q

PT Examination: Infancy

Sensation

A
  • Sharp test OK
  • Test in quiet state
  • Start @ Distal derms and work way up until noxious stim resp. observed, then stop.
    • Bc everything ABOVE should be intact→ remember like SCI***
56
Q

PT Exam: Infancy

Pain

A

FLACC scale

57
Q

PT Exam: Toddler/Preschool

A
  • ROM/strength thru observation of functional skills
  • Sensation→ Lt. touch typ via tickling→ Age 2***
  • Standardized gross motor assessments approp:
    • PEDI
    • PDMS-2
    • Functional Activities Assess.
    • Wee-FIM (inpatient)
58
Q

PT Examination:

Spina Bifida

*Progressive CNS dysf common @ this age…..

A

SCHOOL AGE!!!!

59
Q

PT Examination: School Age

A
  • Examine all prior→ sensation, coord, fine motor, gait, mobility, body aware, pain, endurance, functional skills→ all more objective @ this age***
  • ***Progressive CNS dysf common @ this age!!!
    • monitor rapid pds of growth 2* risk motor loss and tethered cord
60
Q

PT Exam: Adolescence/Transition to Adulthood

A
  • Balance/posture→ higher lvl ADLS as body composition changes/has impact
  • Teens means of mobility may change
    • progress. of neuro, alignment defs, post-op comps
  • Skin integrity primary concern→ 2* incd wt = sweat= skin breakdown
  • PT plays lg role in post-ortho sx (scoliosis, LEs)
61
Q

PT Tx:

A
  • Education across lifespan→ positioning, ROM, skin inspect, handling (newborns esp.)
  • Equipment→ DME, orthotics, adaptations for devices (ex. carseats)
    • *allow compensations to inc IND (long handled mirrors and reachers for skin inspect.)
  • Strengthening
  • Encourage independence
    • pre-k/early school age→ huge for asserting IND w/ basic self care/ADLs
  • Mobility training
62
Q

PT Tx Continued:

A
  • Post-ortho sx→ return to PLOF
    • home mods
  • Ongoing adjustments HEP
  • Advocate for pts!!!
    • adapting classes, address part. restrictions and enrollment in comm. activities and wellness programs→ combat obesity and decd social interaction
63
Q

Across the Life-Span

Focus on:

A
  • Monitor s/s shunt malf., changes/progression neuro impairs, jt align/muscle length,
  • Maint structural alignment→ specifically @ spine
  • improve/maint. strength, cog limits w/ respect to motor learning, encourage fitness/health,
  • Refer as needed and work closely w/ team!!!
