PTA Neuro 10.20.09
Children w/Spina Bifida
| Question | Answer |
|---|---|
| what is the best defense against spina bifida? | women who are sexually active should take 40 mg (400 mcg) of folic acid/daily |
| myleodysplasia is? | interrupts the signal to the nerves |
| why can you see some stg in a muscle but limited at the level of dmg? | redundant nervous system - many nerves join others |
| musculoskeletal deformities | postural, scoliosis, joint deformities/contractures, crouched gait, vertical tali, hip dislocation |
| neurology impairments | motor paralysis, sensory dysfunction, (these 2 are like SCI), hydorcephalus, cognitive dysfunction, language dysfunction, seizures (10-30%), neurogenic bowel, neurogenic bladder (these are unique to SB) |
| How to tx hydrocephalus? | shunt to drain |
| in what way and what level is cognitive dysfunction | L5, typically low end of normal, often lack executive functioning skills (plan, execute), "cocktail party" syndrome, have good knowledge on a very limited amt of information |
| if L1 - L2 involvement affects..... | have no LE |
| S1 - S2, neurology impairment | neurogenic bowel & neurogenic bladder, sphincter doesn't close all the way, causes skin breakdown b/c they cannot feel when they are wet |
| what is a determining factor in ambulation & independence? | CNS INVOLVEMENT, primary determining factor, not just physical level. |
| what is a way to deal with cognitive dys? | use note cards with ICONS to help them through a process, like how to go transfer to a chair from a wheel chair. |
| when does the dmg occur causing SB? | in utero |
| primary focus of PT for SB? | focus on independence |
| PT care for SB | joint contractures & deformities, pressure sores, brace/wheelchair assessment, independent mobility/self-care |
| what causes a static joint contracture? | contracts at rest |
| dynamic joint contracture is caused by? | antagonistweak apposing muscle such as the anterior and posterior tibia, |
| what if they are L4 involvement but no CNS involvement? | functioning 100% |
| Habitualization is | teaching something new |
| rehabilitation | teaching something they once knew |
| if they are L4, what would you expect to see and why? | no paraneal, opposing muscle, 45 deg DF & inversion or forefoot abd |
| hip flexor contracture due to? | unapposing gluts |
| knee flexion contracture due to? | unapposing quads |
| PF contracture due to? | unapposing Tib anterior |
| Tx for contractures | low load/long duration (strap on brace to pull into position), ROM, positioning |
| with a 20 degree hip flexion contracture, w/AFO & crutches, what affect on gait? | diminish gait velocity to 44% of normal |
| 10 degree hip flexion does what to gain? | reduces gait velocity to 20% of normal |
| what type of surgery would help dynamic joint contracture/deformity? | split posterior tib & put half the tendon higher up on leg to even pull |
| what causes pressure sores | usually due to lack of sensation of buttock, joint deformities & dec activity level are inc factors |
| what can help prevent pressure sores? | catheter thru belly button, pressure mapping, hourly wt shifts |
| why do SB develop severe pes planus | don't have dynamic stabilizers, spring lig & tibialis anterior & anterior |
| what level SB would require AFO? | L4, L5 |
| what kind of AFO for S1? | orthotic |
| what level requires a KAFO? | L3, don't have control of hips, quads, locking jt for knee |
| what is GRAFO? | ground reaction AFO. gives advantage of longer lever arm |
| HKAFO is what level? is it functional? | includes a hip joint, L1, L2. not function, w/c is easier |
| THKAFO | not too functional b/c so difficult to get on & off |
| RGO's | reciprocating gait orthotic, walk with a circumduct, cost $5K, not functional. easier to get along w/wheel chair |
| Parapodium, how does it work and at what age? | helps develop the acetabulum w/WBing. Also helps with head (must have head control) and rotational control. Start around 9 mo. should use 20-30 min, 4-5 x day, not a passive device, add some tilting if possible |
| standing/ambulation benefits | improved bowel/bladder, prevention of bone loss, improved heart endurance, prevention of pressure sores & joint deformities, improved upper extremity stg & coordination, endurance |
| L1, L2 what ambulation trend? | Therapeutic or household walking in childhood or adulthood |
| T2-T12 ambulation | most use wheel chair in adulthood |
| Thoracic 2 to Thoracic 12 ambulation | therapeutic walking in childhood |
| L3 - L4 ambulation | household or community ambulation in childhood/adulthood, KAFO, loftstands maybe but wheel chair more efficient |
| functional trend of L3 | most use wheelchairs as primary mode |
| how many L3 will achieve independence? how many working? | 60% Ind, 20% actively in full time employment |
| L4, percentage ambulate as adults? independence? community ambulation? | 20%, 60% Ind, 20% comm |
| L5 to S1 ambulation trend | community in childhood & adult |
| muscles affected at L5-S1 | all gluts, hamstrings, gastroc (not soleus, will at L1) |
| L5 ambulation - what AD? | crutches are suggested in adults to dec energy expenditure & maintain alignment |
| L5, what % independent? full time work? part time work? | 80% ind, 30% FT, 20% PT, (50% empl as adults) |
| S1 functional | excellent long term, some studies suggest high risk for heel ulcers, infection & amputation, use of heel cups may limit (no sensation) |
| how are independent skills assessed? | PT -new survey in SDC to evaluate function level ( 9 categories) |
| do they have to walk to be independent? | NO |
| how is independence defined for SB? | toilet transfers, bowel/bladder maintenance, dressing/self-care, indoor/outdoor mobility, level surface transfer, car transfer, bed mobility, tub/shower transfer |
| what is the primary reason for not obtaining independence? | limited cognitive skills |
