Laser therapy uses the concentrated use of energy in the form of photons that will trigger regeneration and healing in dysfunctional tissue at the cellular level. Of the laser therapies available, Class IV allows for the deepest penetration necessary that will provide the desired therapeutic result. Damaged tissue tends to be poorly oxygenated and often presents with swelling and inflammation. Laser therapy reduces inflammation and swelling and provides marked pain relief and accelerated recovery in both chronic and acute conditions. Patients experience improved function and mobility.
