Week 1 Flashcards
Neuropraxia
CLASS 1: FOOT FALLS ASLEEP :REVERSABLE - nerve injury that causes temporary and localized loss of function (sensory or motor)
Axonotmesis
CLASS 2: AXON DAMAGE: RECOVERS 1 MM/DAY- localized damage to axon and myelin and varying degree of peripheral nerve connective tissue
Neurotmesis
: CLASS 3 COMPLEATE LASSERATION : SURGERY-severing of axon and myelin and all connective tissue structures
T or F axons that undergo regeneration remyelinate to pre-injury level
False they DO NOT remylinate to pre injury level
Collateral sprouting
Collateral sprouting can be defined as the growth of intact axons into neighboring denervated territory.
Mononeuropathy
peripheral nerve injury
one nerve injured
ex: carpal tunnel syndrome (median nerve)
Mononeuropathy multiplex
peripheral nerve injury to 2 or more nerves and areas
Radiculopathy
peripheral nerve injury
caused by nerve roots
Plexopathy
a disorder of the network of nerves in the brachial or lumbosacral plexus
Peripheral nerve disease risk factors and examples
risk factors: DM, renal failure, alcohol abuse, autoimmune, nutritional, hereditary infection, medication, toxins idiopathic / spontaneous
examples: Sjogren’s syndrome, lupus, rheumatoid arthritis, Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy and vasculitis.
Peripheral nerve disease symptoms and exam items
Symptoms: weakness, numbness, burning pain, distal to proximal symptoms
exam: treat and address early, neuroplacicity and axonal regeneration /collateral sprouting is possible
screen: autonomic dysfunction(: vasodilation, loss of vasomotor tone (dryness, warmth, edema, orthostatic hypotension ) balance and fall risk, end feel, sensoriomotor (hair loss and vascular changes )
Open vs closed packed
closed: max stability and joint surface area
do not mobilize
good for WB
open: minimal surface area in this position
perform mobilizations
great rom
Grades of mobilization with speed, amplitude an range
All slow
Grade 1: small beginning of range
Grade 2: big within range
Grade 3: big middle to end range
Grade 4L baby available range / tissue resistance
Grade 5: fast/ high velocity small amplitude
End feels
Soft : tissue /muscle
Hard : bone cartilage
Firm: ligament/ tendon, capsular
Empty : pain
Boggy: edema /swelling
Isometric vs isotonic vs isokinetic
Isometric: no change in muscle length
Isotonic: change in muscle length with force staying the same
Isokinetic: constant velocity of muscle action (requires special equipment)
Osteokinimatics vs arthrokinimatics
osteo = bone motion
arthro= joint motion
