Laser Therapy ApplicationsLaser Therapy Applications
• Pain Relief
• Expedited recovery from injury

Osteoarthritis Osteoarthritis
• degeneration of the connective cartilage in joints
• causes swelling, joint pain, decreased motion
• no pharmacology to treat

Methods and ResultsMethods and Results
• used three different laser therapies:– single-wave– two-wave doses: 12.4 j/point, 6.6 j/point
• Decreased swelling and pain • Increased range of motion• Two-wave 12.4 j/point
– pulsation promoted cell repair – steady beam decreased pain
[4]
Treating Raynaud’s PhenomenonTreating Raynaud’s Phenomenon
• circulatory abnormalities cause extremities to be extremely sensitive to cold and emotional stimuli
• treated with Multiwave Locked System LT • Promotes the production of VEGF to work with Ang-
2 promoting cell activation• Circulatory function and growth returns to normal • Decreased Attacks
– frequency (20-15 /week) – time (15.0-10.0 min)
[2]
Postmastectomy LymphedemaPostmastectomy Lymphedema
• swelling of lymph nodes and surrounding are
• single-wave therapy• stimulates
lymphatic pathways

ConclusionConclusion
• Phenomenal potential is treating chronic pain
• Attacks conditions typical pharmacology cannot address
• Easy and cost affective application
• Wide-variety of treatments using one device
