Healthy blood circulation is important to overall health and well-being, as strong and steady local blood flow delivers fresh nutrients to the cells and prevents accumulation of waste materials within the cells necessary to maintain healthy cell function. Conversely, poor local blood circulation can cause numerous acute and chronic health problems, and can manifest itself in symptoms of pain, numbness, weakness and swelling, and can exacerbate these symptoms in co-existing acute and chronic conditions. Chronic conditions that may result from poor blood circulation that is untreated and persists over a long period of time include varicose veins, kidney damage, stroke and heart attack. Memory loss, frequent headaches, dizzy spells and slowed mental response can also result.
Therefore, improving local blood circulation has significant positive implications for both the overall health and well-being of an individual and for improving, relieving and preventing symptoms and long-term complications of poor blood circulation. Treatment to improve blood circulation include simple options such as changes in dietary and exercise habits, and alternative treatments such as acupuncture and herbal remedies. Medications may be prescribed to assist with contributory conditions such as high blood pressure or cholesterol. In more progressed cases, surgical options such as angioplasty or bypass may be performed to treat narrowed or blocked arteries.
However, less invasive options are usually minimally effective, medication has its own risks and side-effects and surgical procedures are invasive and carry significant procedural risks and potential complications. The purpose of this study is to evaluate the efficacy of low level laser therapy as a means of increasing local blood circulation as it is related to reducing chronic heel pain arising from plantar fasciitis that is simple, non-invasive and risk-free.
Low level laser therapy is believed to effect various physiological mechanisms of change that include improved blood flow and increased cell metabolism, advanced healing, anti-inflammatory actions and stimulation of the immune system. The laser directs light energy into the body's cells. The cells then convert this light energy into chemical energy to promote natural healing and pain relief. The laser also allows photons to enter the tissue and become absorbed in the cells mitochondria within which the photonic energy is converted to electromagnetic energy in the form of adenosine triphosphate (ATP). This additional ATP is energy the cell uses to trigger positive physiological responses from the body such as increased cell metabolism and development of muscle tissue and collagen, improvement of blood circulation, stimulation of tissue repair, wound healing and stimulation of the nervous and immune systems.
