Neuro-Orthotics
MODALITIES: Orthotics in Neurorehab
| Question | Answer |
|---|---|
| What are joint considerations we need to consider for Neuro-Orthotics? | -Tension -Pressure -Impact of joint position on hand tissues |
| What is spasticity? | A motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes |
| Does spasticity or hypertonia show an exaggerated stretch reflex? | Spasticity |
| Does spasticity or hypertonia have an UMN injury? | Spasticity |
| Does wearing a splint reduce spasticity? | No |
| What is hypertonia? | Increased muscle tone or rigidity |
| Hypertonia is increase resistance to passive movement caused by what? | Muscle contracture |
| How can hypertonia lease to loss of ROM? | Increased time spent with shortened muscles |
| When does soft tissue shortening begin? | 2 to 4 weeks |
| In order for a splint to be effective it must be worn for at least how many hours? | 6 to 12 |
| What is the degrees for a functional position splint? | -Wrist extension 30 degrees -Fingers neutral -Thumb in palmar abduction |
| A functional position splint has the FDP and thenar muscles at what length? | Shortened |
| What is a maximal length splint? | Emphasizes extension of wrist, finger, and thumb |
| What is the degrees used in a maximal length splint? | Wrist extension 35 degrees |
| How are the MCPs positions in a maximal length splint? | Open-packed but will spend 16 hrs a day in a flexed position if pt stays on schedule |
| With muscles placed at maximal length tissue elongation and increased sarcomere production will occur where? | Flexor muscles |
| What is the ideal time frame for a low-load prolonged stretch? | 6 to 8 hours |
| Does soft tissue grow or stretch? | Grow |
| What is the Seabo Stretch? | Splint that has a dynamic hand piece that allows the fingers to move through flexion caused by postural changes, associated reactions and tone. It will gradually move the fingers into extension |
| Orthoses fabrication is an adjunct to the POC and needs to be coordination with what? | Neurotoxins, NMES, HEP, stretching and strengthening |
| Is there evidence to support splinting? | -No significant difference in ROM -Mainly measured spasticity which isn't an indicator of function -Decrease in pain |
| What happens if a rigid splint is worn during activity? | Hypertonicity will increase and fingers will move into flexion |
| Where do straps need to be in order to secure fingers? | Below the PIP joints |
| Do you need a separate strap for the small finger? | Yes |
