Ultrasound

Ultrasound functions to speed up tissue healing, decrease swelling, decrease pain, and increase tissue extensibility.  It does this through mechanical and thermal (heating) mechanisms.

Mechanical: these benefits arise due to two separate phenomenon 

Cavitiation:
occurs due to pressure changes, gas bubbles oscillate (compress with peak of wave & expand with valley)

Acoustic (Micro) Streaming:
one directional motion of fluid caused by sound wave 

Mechanical Benefits include:
  • improves cell membrane permeability (opens protein channels for exit and calcium channels to enter                     ­ 
  • increases macrophage activity
  • causes stronger more elastic connective tissue              ­ 
  • increases cytokines                               ­ 
  • increases blood flow                              ­ 
  • increases fibroblast activity                  
  • reduces edema formation        
  • can also help drive topical medicine into the tissues                     

Thermal: (same as superficial heating but deeper)
  • increases nerve conduction velocity   
  • increases extensibility of collagen based structures 
  • increases blood flow
  • enhanced adhesion of leukocytes                      ­ 
  • increased bradykinin                           ­ 
  • increased metabolic activity       
  • reduces spasm
  • increases venous & lymphatic return 
  • increases oxygen dissociation off hemoglobin
  • improves strength & function of collagen tissue
  • reduces pain: decreases mechanical pressure, reduces spasm (decreased firing of gamma & alpha motor neurons), decreased ischemia
