Laser Therapy (LLLT) or Phototherapy
Effects
- Immunological chain reaction triggered involving procollagen synthesis in fibroblasts, increase number of mast cells, activation of macrophages
- Increase number of endothelial cells and keratinocytes
Acceleration of the Inflammatory Process
The following reactions have been shown to occur in sequence at points of high laser light intensity:
- Changes permeability of cell membranes to Ca+, Na+ and K+ ions
- Influences proton gradient over mitochondria membranes
- Serotonin level in blood
Pain Influence
The following reactions have been shown to occur in sequence in areas of high difference in light intensity levels:
- Local differences create temperature and pressure gradients across cell membranes
- Changes permeability of cell membranes to Ca, Na and K
- Influences proton gradient over mitochondria membranes
- Decrease Bradykinin
- Decrease C fibre activity
- Increase of synthesis of endorphin
- Increase nerve cell action potential
