Intro, Inflammation, Tissue, Pain Flashcards
How are physical agents generally described?
As category of energy (thermal, mechanical, electromagnetic) or types (US, water, heat, e-stim, etc)
What are some functions of physical agents?
To help modify tissue inflammation and healing, relieve pain, alter collagen extensibility, modify muscle tone-contracting ability
What are the phases of healing?
Inflammatory, Proliferative, Maturation
Describe and state the usual time frame of the inflammation phase.
Prepares wound for healing, 1-6 days
Describe and state the usual time frame of the proliferation phase.
rebuilds damaged structures and strengthens the wound, 3-20 days
Describe and state the usual time frame of the maturation phase.
Modifies scar tissue into its mature form - day 9 onward
What types of factors can affect the healing process?
Local, external, systemic
State some external forces that affect healing process.
Utilizing modalities, proper nutrition, environment
State some systemic forces that can affect the healing process.
Conditions that can increase edema and decrease circulation (vascular diseases, diabetes, tissue disorders, etc.), proper nutrition
Why does cartilage have limited ability to heal?
Lack of lymphatics, BVs, and nerves
What are some factors can affect the ability of a tendon or ligament to heal?
type and extent of damage, vascular supply, and control of movement
If a tendon does heal what will happen?
will possess a unique scar maturation phase that can achieve an advances state of repair
How can healing occur to skeletal muscle?
In some cases through stem cells
What can develop after a severe contusion to a muscle?
Calcified hematoma
What are the four stages of bone healing?
inflammation, soft callus, hard callus, bone remodelling
What happens in the inflammation phase and when does it occur?
Creates hematoma, disrupts blood supply, lowers pH. shortly after impact
What happens in the soft callus phase and when does it occur?
stabilizes fx, decreases pain, and reduced chance of fat embolism. begin after swelling subsides
What happens in the hard callus phase and when does it occur?
clinical healing period. 3 weeks-4 months
What happens in the bone remodeling phase and when does it occur?
healed fibrous bone converted to lamellar bone and medullary canal becomes patent again. months to years
What is the most common symptom prompting patients to seek care?
pain
What is the definition of pain?
An unpleasant sensory and emotional experience associated with actual or potential tissue damage
What is pain a warning of?
actual or potential tissue damage
Describe some methods for assessing pain.
Visual analog and numeric scales, comparison with a predefined stimulus, daily activity/pain logs, body diagrams, interviews, physical exam and testing
What neurons respond to intense mechanical stimulation and heat or cold?
A delta
