Biophysical Agents Unit 1 Flashcards
What do therapeutic modalities represent?
A diverse group of interventions that add to and complement other therapies in a comprehensive rehabilitation plan.
Name two types of heat therapy modalities.
- Hydrocollator pack
- Paraffin
What is the purpose of diathermy?
Provides heating of deep tissues and may precede stretching or other range of motion activities.
What is the role of electrical stimulation in therapy?
Facilitates functional activities.
List two mechanical modalities.
- Traction
- Compression
What is the primary goal of modulation of pain?
To alter the perception of pain through various therapeutic techniques.
A-delta nerve fibers respond to what types of stimuli? What 3 stimulus are associated with A-delta Nerve Fibers?
- Mechanical and thermal stimuli
- Becomes Sensitized by sharp, stabbing, pricking stimulus (its short-lasting)
What type of pain is characterized by lasting less than 3 months?
Acute pain.
True or False: Chronic pain is associated with structural and functional changes in the CNS.
True.
What is referred pain?
Pain at a site remote from the source due to convergence of various nociceptors on spinal nerve root.
Fill in the blank: The control of acute inflammation involves ____ nerve conduction velocity.
Decrease
What are NMES and FES used for?
To increase strength, endurance, and functional use of skeletal muscle.
What is the goal during the inflammatory phase of healing?
Reduce blood flow and decrease cellular metabolism to lessen the formation of edema.
What happens during the proliferative phase of healing?
Enhancement of blood flow and cellular activity.
What is a key benefit of heating collagen in tissue therapy?
Facilitates elongation and deformation of collagen fibers, resulting in sustained gains in flexibility.
