Superficial Cold and Heat Flashcards
1
Q
Purpose of Crytotherapy
A
- is used to control inflammation, pain and edema; to reduce spasticity; to control symptoms of MS; and to facilitate movement
2
Q
Effects of Cold
A
- Initial Vasoconstriction
- Later Vasodilation
3
Q
Neuomuscular Effects of Cryotherapy
A
- decrease nerve conduction velocity
- elevating the pain threshold
- altering muscle force generation
- decreasing spasticity
- facilitating muscle contraction
4
Q
Contraindications for Cryotherapy
A
- Cold hypersensitivity
- Cold intolerance
- Cryoglobulinemia
- Paroxysmal cold hemoglobinuria
- Raynaud’s disease or phenomenon
- Over-regenerating peripheral nerves
- Over an area with circulatory compromise or peripheral vascular disease
5
Q
Precautions for Cryotherapy
A
- Over the superficial main branch of a nerve
- Over an open wound
- Hypertension
- Poor sensation or mentation
- Very young and very old pt’s
6
Q
What temp should the freezer be kept at and how often should you check it?
A
- 23 Degrees
- Once a day
7
Q
Thermotherapy
A
- is used primarily in PT to control pain, increase soft tissue extensibility and circulation, and accelerate healing
8
Q
Effects of Heat
A
- Vasodilation
- Increase Blood Flow
9
Q
Neuromuscular Effects of Heat
A
- Increases nerve conduction velocity and decreases the conduction latency of sensory and motor nerves
- Increase pain threshold
- Initially decrease muscular strength
- Increased Metabolic Rate
- Increased collagen extensibiltiy
10
Q
Contraindications for Thermotherapy
A
- Recent or potential hemorrhage
- Thrombophlebitis
- Impaired sensation and mentation
- Malignant tumor
- IR irradiation of the eyes
11
Q
Precautions for Thermotherapy
A
- Acute injury or inflammation
- Pregnancy
- Impaired Circulation
- Poor thermal regulation
- Edema
- Cardiac Insufficiency
- Metal in the area
- Over an open wound
- Over areas where topical counterirritants have recently been applied
- Demyelinated Nerves
12
