Nerve Pathology
Nerve Impingement
Systemic Nerve Disease
Congenital/Developmental
Injury
Radiculopathy
Tumors
disc pathology leading to a decrease in disc height
Brachial Plexus C5-T1 including MC, median, radial, ulnar, axillary, and other branching nerves
amyotrophic lateral sclerosis
Lumbosacral Plexus L2-S2 including Femoral, sciatic, and other branching nerves
SC injuries
double crush syndrome
Thoracic Outlet Syndrome: compression of neurovascular structures (brachial plexus, subclavian artery and vein)
Neurotension
Spinal Stenosis
whiplash
scoliosis
congenital Degenerative disc disease
congenital degenerative joint disease - strongly linked to family history

True Signs
False Signs
specific myotome weakness
specific dermatome sensory changes
radiating pain in dermatomal pattern
increased myoelectric hamstring activity
Decreased SLR
mild nerve injury can lead too
adherance
shortening
loss of elasticity
general irratation
carpal tunnel a common example
typically a nerve root and peripheral nerve
possible sources
meninges
axon connective tissues
adhered denticulate ligaments
can lead to physical and psychological changes
quick stress to the neck with high force, ex. car accident
vulnerable locations
Tunnels
Branching points
fixed points
close to unyielding structures
psychological changes such as PTSD and fear of movement
physical: loss of motion, loss of balance, decreased strength, altered recruitment patterns

reduction in
axoplasmic flow: the movement of nutrient dense cytoplasm from the cell body to the rest of the nerve fiber
blood supply to nerves
can lead to loss of motor function and sensation
from traumatic accidents such as car accidents or falls
congenital
Acquired usually through age-related narrowing
pain worse in extension
Remember the horses!
The main symptom is progressive muscle weakness leading to large impacts on physical function
a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord
Neuron and glial cells may develop tumors thus decreasing space in the nerve canal
Osteochondroma: most common benign tumor found on bone, may impinge nerve canals

Multiple sclerosis
symptoms can include: vision loss, pain, fatigue, impaired coordination, cramping, muscle weakness
auto-immune condition that attacks the myelin sheath of the nerves of the CNS
Guillain Barre syndrome
leads to muscle weakness and wasting
auto-immune condition that attacks the peripheral nerves
