Phases of Healing: 1. Inflammatory Response Phase

A
  • Chemical messengers elicit local and systemic effects, cells remove debris, and cells create groundwork for repair/regeneration
  • Lasts 3-4 days
  • Purpose: protect, localize and prepare for healing

- Move sound head in slow manner to prevent hot spots (4cm per sec)

79
Q

  2. Pad (bladder)
  3. Water immersion method
80
Q

US thermal Effects

  • Vigorous heating = 4 degree C results in improved viscoelastic properties of collagen
81
Q

Non-Thermal US effects

A
  • Pulsed US

- Due to Cavitation and Acoustic Microstreaming

82
Q

Cavitation (2 kinds)

A

=Formation of gas filled bubbles that expand and compress, causing pressure changes in tissue fluids

  1. Stable cavitation = rhythmic contraction and expansion of gas bubbles; facilitates fluid movement and membrane transport (GOOD)
  2. Unstable cavitation = formation of bubbles at the low pressure part of the US cycle; results in bubble collapse and tissue damage (BAD)
83
Q

Acoustical Microstreaming

A
  • Unidirectional movement of fluids along the boundaries of cell membranes
  • US causes interstitial fluids to flow and strike cell membranes
