LASER AND HUMAN MEDICINE
Again…what are the effects of the laser light?
- Improvement of healing processes
- Pain reduction/analgesic effects
- Anti-inflammatory effects
- Anti-Oedema effects
- Fibrinolytic activities
- Improved blood flow
- Relaxation and break-up of myogelosis, improved mobility, better motor functions and relexation of blockades

Laser for pain relief:
Any cell has more negative charge than its environment, thus a potential difference arises. In a state of rest it is 90 mV and is called equilibrium rest potential – it is caused by the unequal distribution of potassium= and sodium+ ions in the cell membrane. The unequal distribution is caused by a Na+ - K+ pump that pumps Na ions out of the cell. More than 40% of the energy available in a cell is used up by this pumping activity.
Stimulating a nerve cell aggravates the flow of ions through the cell membrane – the membrane becomes permeable. Potassium ions leave the cell and sodium ions penetrate into the cell, a depolarisation is developing. This changes the sign of the
potential differenceto the static condition.
The cell interior has a positive load to the extra-cellular liquid. The potential difference is +/- 30mV. This process proceeds along the nerve fibres. To re-polarize the cell membrane and restore a static potential of +/- 90 mV it is necessary to activate the Na+ pump, which needs a lot of energy. The ATP hydrolysis provides this energy. The laser blocks the penetration of Na+ ions into the cell and increases the ATP production.
Furthermore it is well known that the photon load of the laser appeals to the lipids of the neuron membrane. Lipids are oblong molecules that react like liquid crystals, arranger in a double layer vertically to the cell membrane. Laser light mobilizes and empowers them to block the ion penetration channels and aggrevate a depolarization.
Laser for wound healing:
The process of wound healing is also a very energy intensive process for
- activating the phagocytosis and dissolve bacteria- and cell detrius (immediately after receiving an injury)
- a high glycol=protein distribution (approx. 5 days later during the exudative phase
- a high rate of collagen synthesis (proliferate phase after 10 days)
- rearrangement and hardening of the new-built tissue.
Further biological effects are:
- stimulation of formation of anabolic substances like serotonin and bradykinin
- positive influence of enzymatic reactions in the cell
- increase of cell energy in pathological cells which have a huge energy deficit
- expedited conversion inflammation stimulating to inflammation obstructing prostaglandins and prostacyclins
- increase of fibrinolytic activities
Patients bio-feedback:
Normally the patient does not feel the laser treatment. In some cases the patient experiences
- a slight prickle
- warmth in the treated area (metabolism and blood flow are simulated
- slight pain on open wounds
- a little pulsation in the treated area
