Mid term Flashcards
Specific heat?
The amount of energy required to raise the temperature of a given weight of a material by a given number of degrees
Uses Of Cryotherapy(7)
Edema Control Pain Control Inflammation Control Modification of Spasticity MS Symptom Management Facilitation Cryostretch
Cryo contras?(4)
Hypersensitivity to Cold Cold Intolerance Raynaud’s Disease Circulatory Compromise/ PVD Edema caused by poor circulation (red, hot, etc)
Temps 1 Paraffin 2 Ice massage 3. Moist heat (MHP) 4. Cold (CP)
- 126-134

Effects of heat (thermo)(5)
Vasodilation Changes in Nerve Conduction Velocity Increased Pain Threshold Changes in Muscle Stregnth Increased Metabolic Rate
Precautions cryo?(6)
Over a superficial main branch of a nerve Over an open wound Hypertension Poor Sensation Poor Mentation Very Young/ Very Old patients
Precautions thermo?(10)
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
Contras heat?(6)
Recent or Potential Hemorrhage Thrombophlebitis Impaired Sensation Impaired Mentation Malignant Tumor Infrared Irradiation of the eyes
How is heat xfered in conduction?
Direct collision of the molecules of materials. Heat goes from the mat with the higher temp to the one with lower temp.
How is heat xfered in convection?
Occurrs as the result of direct contact between a
circulating medium and another material of a different temp
Neuro MM effects of Thermo?(3)
1.> nerve conduction,
< conduction latency. Can block conduction in demyelinated NNs
2.> Pain threshold(gate theory)
- < mm str
How is pain blocked according to the gate theory?
A-delta (small myelinated) nerve fibers and C fibers (small unmyelinated), activate and block A-beta nerves o block pain transmition.
