Detailed Description
PURPOSE:
To determine the effectiveness of low level laser therapy on insulin resistance and inflammatory biomarkers in obese postmenopausal breast cancer risk women
BACKGROUND:
The American Obesity Association (2002, 2003) defines obesity as 'a complex, multifactorial chronic disease involving environmental (social and cultural), genetic, physiologic, metabolic, behavioral, and psychological components'. However, the most commonly used definitions of obesity are based on BMI, which is defined as weight in kilograms divided by height in meters squared. In adults, obesity is generally defined as a BMI of 30.0 or greater. Obesity has become a major contributor to the global burden of chronic disease and disability. It is a complex condition with serious social and psychological dimensions, affecting virtually all ages and socioeconomic group Obesity is associated with an increased risk of developing insulin resistance and type 2 diabetes. In obese individuals, adipose tissue releases increased amounts of non-esterified fatty acids, glycerol, hormones, proinflammatory cytokines and other factors that are involved in the development of insulin resistance. In overweight and obesity, there exists low-grade chronic inflammation characterized by the increase of cytokines and serum concentrations such as fibrinogen and C-reactive protein (CRP) The areas of low - intensity laser use have expanded in several conditions by different mechanisms and ways. LLLT has been used as an important tool for the control of the inflammatory process. Its anti-inflammatory effect has been studied and its ability to induce analgesia under different conditions has also been reported. Because laser acupuncture appears to be safe, it could be considered as a complementary form of palliative care for prevention of cancer risk, especially for clinical problems for which conventional care options are limited. Investigations suggest the benefits of low-level laser therapy (LLLT) to improve noninvasive body contouring treatments, inflammation, insulin resistance and to reduce body fat.
HYPOTHESES:
Low level laser therapy in form of laser watch has no effect on insulin resistance inflammatory biomarkers in obese postmenopausal breast cancer risk women

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: low level laser in addition to diet recommendations
The laser consists of a semiconductor and operates at a wavelength of 650 nanometre.
The laser installed in the watch comprises 10 individual laser beams for the wrist and an additional adapter for nasal stimulation.
The output power is 5 megawatt, but it can also be adjusted.
The device operates at an ambient temperature of -20 to +40 ° C and a relative humidity of ≤ 85%.
The laser watch can be used for a variable irradiation period of 10-60 min.
the device will be applied on specific acupuncture points (N acupuncture point, Radial artery acupuncture points, and ulnar artery acupuncture points) combined with nasal laser irradiation at the same time, once per day, 3 times per week for three months
