What are physical agents? correct answers Energy and materials applied to patients to assist in
rehabilitation
may include heat, cold, water, pressure, sound, electromagnetic radiation, and electrical currents
Hot pack correct answers produces the greatest temperature increase in superficial tissues with
high thermal conductivity in the area directly below it
Types of Thermal Agents:
Ultrasound correct answers produces heat in deeper tissues and produces the most heat in tissues
with high collagen content and thus high ultrasound absorption coefficients, such as tendon and
bone
Types of Thermal Agents:
Diathermy correct answers involves applying shortwave or microwave electromagnetic energy,
heats deep tissues having high electrical conductivity
Thermotherapy vs Cryotherapy Effects correct answers Thermotherapy (heat): *increase*
circulation, metabolic rate, soft tissue extensibility, or to decrease pain
Cryotherapy (cold): *decrease* circulation, metabolic rate, and pain
Types of Thermal Agents:
, What is ultrasound? correct answers is a physical agent that has both thermal and non thermal
effects
defined as sound with a frequency greater than 20,000 hertz
mechanical form of energy composed of alternating compression and rarefaction waves
Types of Ultrasound: correct answers Continuous ultrasound: is used to heat deep tissue to
increase circulation, metabolic rate, soft tissue extensibility, and decrease pain (thermal effects,
deep and superficial)
Pulsed ultrasound: is used to facilitate tissue healing or to promote transdermal drug penetration
by non-thermal mechanisms (non-thermal effects)
Types of Electromagnetic Agents:
What are electromagnetic agents? correct answers apply energy in the form of an electrical
current or electromagnetic radiation
agents include infrared (IR) radiation, light (via photobiomodulation), UV radiation, and
diathermy
Additional Info correct answers depolarize nerves -> control pain, increase muscle strength and
control
repel charged particles and alter cell membrane permeability -> control the formation of edema,
promote tissue healing, and facilitate transdermal drug delivery
Lasers correct answers produces heat in superficial and deep tissues
Types of Electromagnetic Agents:
Pulsed shortwave diathermy (PSWD) or non thermal shortwave therapy (SWT) correct answers
provides a low average intensity of energy
