Summary of the SCI lesson given by prof. K. Bruyninckx of the physiotherapeutic theory course. It is a summary of the powerpoint slides and additional items noted during the lesson. The slides were in English and my own notes are always in Dutch as much as possible. It is therefore a mix of the 2 l...

Physioth. Theory: spinal cord injury
introducTION
 A Spinal Cord Injury (SCI) is damage or trauma to the spinal cord that results in a loss or impaired function
causing reduced mobility or feeling
 Paraplegia: impaired function in trunk and lower limbs
 Tetraplegia: impaired function in upper limbs, trunk and lower limbs
- = quadriplegia

ETIOLOGY
 Incidence: 1- 000 a year
- = ± 200 in Belgium
 Tetra/paraplegia: 50/50
 Complete/Incomplete: 50/50
 Tendency towards more tetra, more incomplete




LOSS OF FUNCTION
MOTOR FUNCTION
 Usually the upper limb were you will see the clear cut
 Welke spieren aangedaan op welk level




SENSIBILITY
 Touch
 Pressure
 Temperature
 Pain
 Proprioception
 Vibration



AUTONOMIC

 Cranial nerves are usually in tact

SPINAL CORD ANATOMY
 Complete transection = complete
loss of function
- Maar 30% complete leasie
 Incomplete transection
- Amount of damage
- Neuro-anatomy


 Posterior or anterior cord syndrome
- Posterior
 Proprio + vibration + touch
- Anterior
 Motor + pain + crude touch
- Vascularisation: specific symptoms as it is vascularised by its specific arteries

 Sustained pressure: central cord
- Nerve roots that are about to exit the …
- C4-C6 lesion: arms are affected
- C5 is ernstig aangedaan
 Aangedaanheid mindert naarmate verder naar distaal
o C6 minder
o C7 nog minder,…
 Kan dus armen niet gbruiken of deze zijn het meeste aangedaan
 C5 is in midden RM
o Door inhibiting bloedflow àhoe dieper deze moet gaan hoe moeilijker te bevoeien

 Cauda equina (L2-S5)
- = lower motor neuron lesion
- Lage leasie
- Lijkt meer op perfire zenuwaandoening maar is wel aandoening van RM
- Geen spasticiteit à refexboog niet aangedaan



CONSEQUENCES

FUNCTIONALITY
 Everything is going to happen in a different way!

RESPIRATORY
 Inspiratory = innervated high
 Expiratory = innervated lower
- most problems in SCI
- Meeste aangedaan
- Hoesten ook bemoeilijjkt
 Central cord
- inspiratory functions > expiratoir
 Higher risk of:
- Insufficiency
- mucus production
- obstructive sleep apnea (OSA)
- atelectasis
- pneumonia / bronchitis (lange termijjn)
 second most common cause of death
SPASTICITY


Nala Melis Pagina 2

, Physioth. Theory: spinal cord injury
 Definition: “spasticity is a motor disorder characterized by a velocity dependent increase in tonic stretch reflexes
(muscle tone) with exaggerated tendon jerks, resulting from hyper-excitability of the stretch reflexes, as one
component of the upper motor neuron syndrome.”
 70% of patients:
- Loss of inhibiting nerve tracts
- Acute: spinal shock
 First 2-3 weeks everything will be hypotonia
- Big differences between patients and compared to patients with other upper motor pathologies
- Hoe vroeger de spasticiteit komt, hoe hoger deze gaat evolueren
Negative effects Positive effects
- Functional - Trophicity
- Pain - Blood perfusion
- Contractures - Functional àin balans krijgen om functioneel te gebruiken
- Decubitus àdoor willekeurige bewegingen Extension spasticity can be handy to stand up
- Relaxation/sleep muscles working so they ask for blood perfusion
 Not the goal to get rid of spasticity, but to find the balance between negative and positive effects

1. TREATMENT
 Oral (Lioresal, …)
- Small effects, long way to get to muscle
- Veel effectiviteit verloren door lange weg af te leggen
- Veel bijwerkingen
 Intrathecal baclofen
- Less side effects, higher dose at the level it is needed
- It is an invasive treatment! It needs to be filled (4-5m) and pump needs to be replaced (8-10y)
- It is all or nothing, so it is good for P with not so much functionality
- Best for P that are not walking, and it works best for trunk and LL because the catheter is not able to be
places really high
- Rechtstreeks in RM
- Hogere dosis geven zonder de bijwerkingen
- Geen specifieke spieren behandelen
- Meer werking op benen dan armen & handen

 Botox
- Works for 6 months
- Zeer spier specifiek
- Maar beperkte hoeveelheid geven want wordt indine te hoog toxisch

 Mobilization?
- It does work, it lower spasticity for a short term of time
- Kan helpen voor verlagen
- Stijgt terug na een paar uur
- Doen als voorbereiding op oefentherapie

 Functional electrostimulation (FES)?
- Short term, for few hours it works, but no long term effect

 Shockwave ?
- It works a bit longer (days – weeks) but not sure what the LT effects are
- Main benefit = choose what muscle you want to have an effect on (~botox)
- nu experimeneren
- LT-effecten nog onderzoeken
- Doet wa hetzelfde als botox



 Neurotomy / rhizotomy
