Treatment with High-intensity laser for pain relief:
A high-Intensity Laser is a device that produces light of one or more specific wavelengths. A laser beam transmits energy that spreads through the tissue and can be used to treat inflamed, torn, damaged, or infected tissue. High-intensity laser therapy can help with pain, mobility, swelling, and circulation, and healing, often associated with neuropathy, Arthritis, and injuries.
High-intensity laser non-invasively penetrates the skin and spreads further into the muscle, tendon, subcutaneous fat, and bone tissue. Depending on the location of the treated area, the process through which laser heals the damaged tissue is called photo biostimulation.
Upon application of laser therapy on human tissue, there are four different effects that occur: Reflection- the light doesn’t penetrate the tissue. Scattering- dispersion of light randomly in the tissue. Absorption- the tissue absorbs the light. Additionally, carrying the laser further into the tissue structures during transmission, before absorption of light into the tissue.
Effect of laser therapy:
There are three key effects of therapeutic high-intensity laser Photo-acoustic (photo-acoustic waves are created when the area is irradiated by using very short pulses with a high repetition rate), biostimulation (it means stimulating the organism on the cellular level), and thermic.
The high-intensity laser produces a photo-acoustic effect to stimulate the free nerve ending in the tissue and cause nearly rapid pain relief in the area.
The high-intensity laser produces Bio-stimulation to enhance healing and recovery. High-intensity laser therapy can cause a faster exchange of oxygen and metabolites to mitochondria and mitochondria further stimulate to the synthesis of ATP, ATP allows for the faster synthesis of RNA and DNA and leads to quicker recovery, healing, and edema reduction in the treated area.
The thermic effect of high-intensity laser therapy is by the absorption of the laser beam in the superficial structures which consequently causes a temperature increase in the tissue. The thermic effect also causes vasodilation as a consequence blood profusion increases, delivering larger amounts of oxygen to the tissue and more metabolites are resorbed.
Indication of high-intensity laser:
- Sports Injury
- Trigger point
- Herniated Disc
- Cervical pain
- Lower back pain
- Degenerative Arthritis
- Muscle strain
- Medical effects of high-intensity laser are:
- Analgesic effect
- Microcirculation stimulation
- Anti-inflammatory effect
- Muscle relaxation
Benefits of laser therapy over other treatments.
- It is non-invasive.
- Deep tissue penetration.
- Immediate pain relief.
- effective, non-addictive method of treating pain.
- Useful in treating muscle or joint injury.
