A

increase in tensile strnegth and decrease in fibroblasts is a sign for maturation and remodeling phase

  • separation of tissue
  • muscle spasm
  • atrophy (degeneration of cells)
  • corticosteriods
  • keloids and hypertrophic scars
  • infection
  • humidity/climate
  • age, health, nutrition
18
Q

What is better controlled mobilizatoin or immobilization?

A

controlled mobilization
- decreases scar formation
- increases revascularization
- facilitates muscle regeneration
- reorientation of muscle and ligament fibers

19
Q

P.R.I.C.E.

A

protection
- protect from additional injury using splints

rest
- allow the inflammatory phase to do what is suppode to do

ice
- decreases metabolism to control secondary hypoxic injury
- analgesia
- vasocontrition
- ice bags, cryocuff

compression
- reduces space for swelling
- elastic wrap and compression dressing
- intermittent compression, cryocuff, elastic wraps

elevation
- reduces pooling of blood in the extremities
- facilitates venous and lymphatic drainage

20
Q

modulating pain

A
  • low-power laser
  • cold
  • e-stem
21
Q

facilitating healing

A
  • low intensity ultrasound (can be used immediately following injury)
22
Q

modalities for inflammatory response phase

A
  • cryotherapy shoudl still be used to reduce likelihood of swelling
  • intermittent compression can decrease swelling (encourages resorption of by products by lymphatic system)
  • estem currents and low power laser can be used to help reduce pain
  • incorapate active and passive ROM exercise
23
Q

modalities for fibroblastic repair phase

A
  • may change from cold to heat
  • thermotherapy (encourages circulation to the injured area)
  • heat can produce some analgesia
  • intermittent compression can facilitate removal of injury by products
  • estem currents assist process by eliciting a muscle construction
  • continue to stress importance of ROM and strenghtening exercises and progress them appropriately
24
Q

modalties for maturation-remodeling phase

A
  • heat modalties
  • deep heating modalties (ultrasound, shortave, and microwave diathermy)
  • superificial heating are less effective
  • estem can be sued to stimulate muscle contractions for increasing ROM
  • low power laser used to modulate pain
  • role of controlled mobility
25
Q

the 3 categories of heat

A
  • chemical action associated with metabolism
  • electrical or magnetic currents as those found in diathermy
  • mechanical action as found with ultrasound
26
Q

A

the application of heat modalties

27
Q

- transfers through conduction, but superficial heating is limited to depth of less htan 2 cm

28
Q

increase cell metabolism and accelerate amount of hypoxic injury

29

  • vasodilation
  • increase cell metabolism
  • increase capillary permeability
  • increase delivery of leukocytes

33
Q

cellular response to heat

A
  • for each increase of 18 degrees farenheit in skin, cells metabolic rate increases by a factor of 2 or 3
