An effective treatment program consists of:
management or reduction of pain associated with injury, return to full non-restricted ROM, maintenance/improvement of strength
How do you choose to use a therapeutic modality?
based on theoretical knowledge/research, practical experience, and patient preference
Modalities should only be used as an _____ to therapeutic exercise.
adjunct
Do modalities speed healing?
no, they create an environment for healing to occur and can remove obstacles that will slow healing
What is the First Law of Thermodynamics?
energy is neither created or destroyed but transformed and transferred from one form to another or one location to another
Transmitted via movement of photons, generated by high energy source
electromagnetic
Transferred by conduction
thermal
Sound vibrations passing through mediums
acoustic
Energy moves from an area of _____ concentration to an area of _____ concentration.
high; low
Heat loss or gain through the movement of air or water molecules across the skin, creating a temperature variation
convection
Heat loss or gain through direct contact
conduction
The process of emitting energy from some source in the form of waves, a method of heat transfer through which heat can be either gained or lost
radiation
Changing from one energy form to another.
conversion
Process by which electromagnetic energy travels from its source through space.
radiation
Energy carrier that composes all electromagnetic radiation.
photon
Distance between peak of one wave and peak of the next wave.
wavelength
Number of wave oscillations or vibrations per second.
frequency
What is the equation for the speed of a wave? What is the relationship between the two
speed = wavelength x frequency, innverse relationship
How fast does a wave travel?
at the speed of light, which stays constant
_____ of a photon is directly proportional to its _____. What is the equation for Plank’s Relation?
energy; frequency, E = h x v
