ice/heat Flashcards
conduction
transfer from a one object to another by direct physical contact
convection
transfer by movement of air or fluid moving past a body part
Radiation
transfer from one object to another object by transmission of electromagnetic energy (microwave
goals for and heat (4)
↓ pain and stiffness
Alleviate muscle spasms
↑ ROM and tissue extensibility
Improve tissue healing by ↑ blood flow
Do you apply heat to edema
no, because increase edema
how many degree C increase to tissue temp equals 2-3x increase in cellular oxidating rate
10 degrees
mechanism elasticity of nonelastic tissue
increase extensibility of collagen tissue
mechanism of improve joint stiffness
Increased tissue extensibility and decreased viscosity
mechanism of muscle spasm
Decreased firing of muscle spindles and increased firing of GTO fibers reduces alpha motor neuron activity
contraindication of heat (6)
Acute inflammatory conditions
Absent sensation
DVT
Impaired cognitive function
Malignant tumor in area of application
Tendency toward hemorrhage
precaustion heat (7)
Cardiac insufficiency
Edema
Decreased sensation
Decreased mentation
Impaired circulation
Metal in treatment area
Demyelinated nerves
moist hot pack method
conduction
how many layers to cover
Must be wrapped in 6-8 layers (hydrocollator covers = 2 layers)
medthod parafin bath
conduction
ratio of paraffin wax with oil
6:1 or 7:1 ratio
