What muscles and muscle actions are innervated by the Radial nerve?
Brachioradialis
wrist extension
triceps
finger extension
What muscles and muscle actions are innervated by the
- suprascapular
- Axillary
- Median/ulnar
- Ulnar
- supraspinatus
- Deltoid
- Wrist flexion, finger flexion
- finger abduction and adduction
If muscle tone is increased what type of lesion is MC associated with it?
UMN
If muscle tone is decreased what lesion is MC associated with it?
LMN
What is hypertonia?
increased muscle tone
what are the two types of hypertonia?
- spasticity
- Rigidity
What is muscle spacticity?
Increased muscular resistance felt by examiner with quick joint movement. termed “clasped Knife”
Tension at first but then followed by decreased tension as the joint is opened
What is muscle rigidity?
Involuntary muscular resistance felt when moving a resting joint and persists as the joint is moved through its ENTIRE ROM
“gooseneck”
What is hypotonia?
decreased muscle tone
If a patient has decreased muscle tone where is the neurological damage?
LMN
at the level of the reflesx arc, cerebellar disease may cause diffuse hypotonia aswell
All neurological signs can be devided into what two phenomena?
- Deficit
- Release
What is the DEFICIT PHENOMENA?
Loss of normal neurological function
What type of lesion only produce the deficit phenomena?
LMN
What is the Release phenomena?
Exaggerations or perversions of normal neurological function.
What types of lesions produce the release phenomena?
UMN
What is the segmental innervation of the Biceps reflex?
C 5-6
What is the segmental innervation of the Brachioradialis reflex?
C 5=6
What is the segmental innervation of the Triceps reflex?
