16
Q

what are the two types of hypertonia?

A
  1. spasticity
  2. Rigidity
17
Q

What is muscle spacticity?

A

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

18
Q

What is muscle rigidity?

A

Involuntary muscular resistance felt when moving a resting joint and persists as the joint is moved through its ENTIRE ROM

“gooseneck”

19
Q

What is hypotonia?

A

decreased muscle tone

20
Q

If a patient has decreased muscle tone where is the neurological damage?

A

LMN

at the level of the reflesx arc, cerebellar disease may cause diffuse hypotonia aswell

21
Q

All neurological signs can be devided into what two phenomena?

A
  1. Deficit
  2. Release
22
Q

What is the DEFICIT PHENOMENA?

A

Loss of normal neurological function

23
Q

What type of lesion only produce the deficit phenomena?

A

LMN

24
Q

What is the Release phenomena?

A

Exaggerations or perversions of normal neurological function.

25
Q

What types of lesions produce the release phenomena?

A

UMN

26
Q
