PBL S&F 4 (neuro exam (postural reactions (paw placement (putting paw…

- - - - tilt
    - - wide stance for balance
  - - - putting paw back correctly when upside down
    - - supporting leg so can't balance, pushing along to see if hop and stop from falling
    - - pick up HLs and make walk forward with front
    - - both L or R picked up and animal walks with just R or L
- - - - 10% have delayed return to ambulation over next 18 months
- - - - atrophies
      - e.g. patellar reflex non-functional
  - - - control LMN
    - - exaggerated response as UMNs have inhibitory effect on muscles
  - - - nerve damage
      - disease
- - - - welfare of breeding
      - stock selection
        
        develops late?
- - - - adapted Ca and P content
- - - - if cuts off at level of SC, lesion is 1-4 vetebrae more cranial as nerves travel along SC before synapsing
- - - - sensory neuron only goes to SC
- - - - reflex arcs, gait, posture
    - - not good for SC imaging
      - disc infection, bone tumours
  - - - SC injuries
    - - view body in "slices"
    - - injecting contract around SC to visualise on radiograph
      - combined with CT often
- - - - decompression surgery
    - - paraplegic and absent nociception risk for myelomalacia - progressive fatal serious condition
      - should be done ASAP <48 hrs after losing ability to feel HL
    - - part of bone of vertebrae removed
        
        removal of oozing nucleus pulposus and part of vertebrae
        
        relieves pressure here
- - - - broken down allowing soft core (nucleus pulposus) to ooze out and compress spinal cord
  - - - compresses SC
- - - - soft inner core of disc oozes out and compresses SC
        
        causes damage to UMN (hyperactive PR) - motor neuron controlling LMN in limb
