Therapeutic Modalities Study Guide QuestionsWith Complete Solutions
_______________ is often used to generate deep tissue heating
and thermal effects Correct Answer Acoustic/sound energy
-Also able to produce non-thermal effects capable of enhancing
healing at the cellular level
___________________ requires a great deal of O2 Correct
Answer Collagenization
_________________________generate currents capable of
producing physiological changes Correct Answer
Electrotherapeutic devices
Stimulate tissue and cause membrane depolarization of tissue
___________________allow for pain perception Correct
Answer Projections - brain pathways
Permit integration of past experiences that form our response to
pain
Most analgesic physical agents are believed to slow or block
impulses ascending along A and C afferent neuron pathways
___________________bleeding from open, damaged blood
vessels Correct Answer Hemorrhaging:
__________________afferent fibers are categorized as wide
dynamic range or nociceptive specific Correct Answer Second
order
,_________________begin making "new" collagen Correct
Answer FibroBlastsExtrudes haphazardly into the wound space
Within 4-6 days post-injury, vascularization is maximal &
collagenization is operating at its peak (Maximum RATE)
Most collagen is laid down within 15-20 days post-injury
(Maximum AMOUNT)
_________________is a measure of how many (how often)
pulses are given to the tissue Correct Answer Frequency
Think "amount of information" and "time between information"
2 pps vs. 120 pps
________________afferent fibers carry sensory messages up the
spinal cord to the brain Correct Answer Second order
________________consists of pressure waves due to
mechanical vibrations of particles Correct Answer
Acoustic/Sound Energy
Relies on molecular collision for transmission
Cannot travel through a vaccum
Acoustical waves travel at speed of sound
________________moves the lymph through the body Correct
Answer External forces: muscle contraction, compression, and
message.
Depends on external force to promote fluid movement
,Muscle compression forces contents towards the junction with
vascular system
Massage, Intermittent compression
________________regenerative activity leading to a period of
scar formation (fibroplasia) and repair of injured tissue Correct
Answer Proliferative ,
Reconstitution: Perfect or Imperfect
Replacement: Scar tissue - primary or secondary union
"FIXING THE INJURY"
"PUTTING THINGS BACK TOGETHER"
"RECONNECTING TISSUE"
______________accumulation of fluid portion of blood in the
tissues Correct Answer Edema
__________increase in tissue volume because of extra fluid and
cellular material Correct Answer Swelling:
__________or _______________afferents transmit impulses
from the sensory receptor to the dorsal horn of the spinal cord
Correct Answer First order/primary
"Hunting Response" Correct Answer Periods of vasodilation
and constriction following prolonged cold application to limit
possible tissue injury due to cold use
, (T/F) Heat is always better at reducing muscle spasms. Correct
Answer F: Local cooling may result in a significant reduction of
muscle spasm greater than with use of heat.
May be related to decrease in pain perception
Cold effective in modifying stretch-reflex mechanism
(T/F) Heat relaxes muscles simultaneously lessening stimulus
threshold of muscle spindles and by decreasing gamma efferent
firing rate Correct Answer T: Thus, muscle spindles are more
easily excited
(T/F) Muscles may be electromyographically silent while at rest
during application of heat. Correct Answer T: but the slightest
amount of voluntary or passive movement may cause the
efferents to fire
Local applications of cold decrease local neural activity
(T/F) Nerve conduction velocity reduction also occurs with cold
application Correct Answer T and it decreases afferent
discharge from cutaneous receptors
(T/F) With compression, cooling rate increases Correct Answer
T
In general, crushed ice packs are applied directly to the skin.
A towel or wrap b/w the ice & skin insulates from the full effect
of the cold.
If used for <60 mins, will not cause frostbite (gel packs are an
exception)
Living tissue freezes <25°F. Crushed ice is 32°F.
No reference to frostbite in <60 min ice app.
